Management of Drought-Stressed Hay Fields

Wednesday, July 30th, 2025

Lots of Bales of Hay for Management of Drought-Stressed Hay FieldsWith drought conditions beginning to ease in many parts of the country, hay growers may have questions about whether to do a late fall mowing or just leave their fields alone until spring. An article in the newsletter published by the College of Agriculture at the University of Kentucky offered some tips.

Unless sufficient rain has fallen, mowing mixed-grass hay fields in mid-fall won’t do much to stimulate regrowth. In fact, mowing dry fields will leave the soil exposed to the sun. As a result, further decreasing soil moisture and increasing stress on root systems. If weed growth is extreme, it might help to mow with the blades set high to clip seed heads before the seeds mature.

Some growth will occur in established hay fields after rain replenishes soil moisture. If enough growth occurs to make another hay harvest possible, schedule a late mowing toward the end of October. Mowing at this time will give plants a chance to accumulate post-mowing energy reserves. This is necessary for winter survival and vigorous growth in the spring.

In some circumstances where plant growth has been minimal because of the dry summer, a late fall mowing is not a good idea. One is in areas where soils are prone to frost heave. Another is when fields are covered with seedlings from a spring planting. In these cases, mowing may lead to more damage than leaving the fields with as much cover as possible.

Soil moisture, forage cover, and degree of drought stress will vary across hay-growing regions, so it is suggested that land owners get specific recommendations from local agricultural extension agents before making plans for fall management of hay fields. J & J Hay can help to answer these questions.

Horse Heat Stress Management: Tips For Keeping Your Horse Cool In Summer

Saturday, July 5th, 2025

Horse Heat Stress Management: Tips For Keeping Your Horse Cool In Summer!

Summer is finally here. Winter blankets have been packed away with care. Bundling up for barn chores and breaking the ice in your horses’ water buckets are now distant memories. As you bring your fly sheets out of storage and hang up fans, it’s time to make a plan for how to help your horse beat the heat this summer.

Understanding Your Horse’s Basic Needs for Horse Heat Stress Management

Not only do the summer months bring warmer temperatures and longer days. They also bring more opportunities to ride and compete with your horse. As temperatures rise, so do the risks of your horse experiencing a heat related stress. This includes dehydration and heat stroke. Keep an eye on your horse and modify your training and horse care program to make the most of your summer riding opportunities.

Water

The average 1000 pound horse at rest drinks 8 to 10 gallons of water a day. When temperatures rise above 70° F, horses in work can drink twice as much. Make sure they have access to clean, fresh and cool water at all times, whether your horse is turned out or in his stall. By drinking cool water, they will be able to lower their body temperature on their own. If your horse isn’t a big drinker, you can encourage water consumption by providing free choice salt blocks in your pastures and stalls.

Shade

Providing shade to your horse throughout the day is almost as important as making sure your horse has access to water. Whether you board in a barn or in a field, shade is needed. Obviously a horse in a stall is provided shade from being indoors, however they will need shade when they are turned out. Make sure your pastures offer several shade options.

If there aren’t shade-bearing trees in your field, offer an escape from the sun with a run in shed. With run-ins, the higher the roof the more air circulation and cooler the shed will be. As shade and water go together in importance, place your water troughs in shady areas.

Do you have a field that doesn’t have much shade? Alter your turnout schedule. Either turnout your horses at night, or if you have a horse that doesn’t require a lot of turnout put him in the field early in the morning. Both of these options will let your horse beat the heat and powerful rays of the sun.

Conditioning

Before the temps rise too much, learn how-to assess the body condition of your horse.

If your horse has been in regular work since the winter weather subsided, he will be more likely to be able to handle the rising temperatures. Horses that are out of shape, overweight and even thin under-muscled horses have a hard time dealing with the extra stress associated with heat.

If your horse hasn’t been in a regular exercise program, slowly build up their fitness and stamina as the heat and humidity rises. This slow and steady approach will help ensure your horse stays healthy and not overstressed this summer.

The Importance Of Equine Electrolytes

You know summer is here when your local Southern States and tack shops start expanding their section devoted to electrolytes.

So what are electrolytes and how do they help your horse in the summer? According to Dr. Marty Adams, Equine Nutritionist for Southern States, “Electrolytes are minerals in the horse’s body fluids and tissues that are involved in muscle contraction, thirst regulation, nerve function and maintenance of blood pH.”

Electrolytes can be found in your hay, pasture and Southern States horse feed. However, horses in work, (especially those who travel to compete) need additional electrolytes to maintain good health and perform at their highest level.

Like humans, horses use sweating as a way to cool off during periods of warm weather and while exercising. When a horse sweats, not only is water lost, but important electrolytes like sodium, chloride and potassium are lost. If too many electrolytes are lost serious problems like fatigue, muscle cramps and horse colic can occur.

Dr. Adams says, “When looking for an electrolyte for your horse, sodium chloride should be listed first on the ingredient list. Second, followed by potassium chloride.” There are two types of electrolytes, salt based and sugar based. While sugar based electrolytes are highly palatable, you won’t meet your horse’s daily salt requirements without feeding a lot of the sugar-based electrolyte.

Electrolytes can be given to your horse in a variety of ways. You can add water and administer via dosing syringe, add the electrolytes to your horse’s feed or add the electrolytes to their water. Each way works equally as well, just figure out what your horse prefers to ensure they are consuming the added electrolytes.

Horse Sweat Is A Good Thing

Often times you hear the phrase “no sweat” when people are referring to something that isn’t a problem. When it comes to horses, no sweat is a big problem. During a hot, muggy day it isn’t uncommon to see horses drenching in sweat when doing nothing more strenuous than simply grazing in the field. Although they may look uncomfortable, these sweaty horses are far more comfortable than their non sweating counterparts. Sweating helps regulate body temperature.

Anhydrosis in horses is the partial or total inability to sweat—and is a problem that can be potentially life threatening. When a horse is unable to sweat, he is unable to keep his internal organs and brain from overheating. Unfortunately no one knows what causes this condition and it can affect any breed, though it is most commonly seen in the Gulf Coast states including Florida and Louisiana.

Signs Of Equine Anhydrosis

  • panting
  • poor tolerance to exercise
  • dry hair coat
  • hair loss (especially around the face and a reduction of sweat)

Immediately contact your equine veterinarian if you think your horse may be experiencing anhydrosis. While there is no cure, you can manage a non sweater in a variety of ways. You can relocate your horse during the summer months, limit physical activity, install barn fans and misters or manage through supplementation. Studies have shown that non-sweaters can benefit from additional Vitamin Eand Selenium supplements. It is thought that these levels are low in horses with anhydrosis.

Adjust Your Horse Care Schedule

When we hit the beach this summer, we are often reminded to avoid the hottest part of the day. Typically is is between 11 am to 3 pm. We are told to apply ample sunscreen. This same rule should apply when trying to determine when to exercise your horse during the summer to try and avoid the heat of the day. When possible try to ride either in the morning or late evening, depending on what works best for your schedule.

In addition to changing the hours at which you ride, change the duration of your ride. A short workout in hot, humid conditions is the same as a longer workout in more pleasant weather, in terms of stress placed on the horse. Take plenty of rest breaks, to help your horse cool down during your exercise session.

After you finish exercising your horse, don’t just drop him off in his stall like a hot potato. Take your time and properly cool him off. Take him for an extended walk, hose him off and brush the water off scraping the water off to speed up the cooling process or put him in front of a fan.

Trailering Your Horse In The Heat

When competing this summer, not only do you need to think about how you will perform your best when you arrive at the show. you need to come up with a plan for how you will safely get your horse to the competition. The heat and humidity of the summer can create oven-like conditions in your trailer. So what can you do?

Tips
  • If you don’t currently own a trailer, consider buying a “cool” trailer to ship your horse(s) in. Studies show that dark exterior colored trailers can be 20-30° hotter inside than trailers that are white or silver in color.
  • Look for trailers that have large windows for maximum airflow and ceiling roof vents to draw air into the trailer. If possible, take a test ride in the trailer yourself to see what the airflow and temperature conditions are like when temperatures rise.
  • Even when the weather is cool and humidity is low, traveling is work for a horse. Riding in a trailer can fatigue a horse. They constantly have to work to balance themselves in the moving trailer. Add in warm temperatures and you can easily have a horse that arrives to its destination dehydrated and fatigued.
  • To minimize fatigue, alter your travel schedule. Transport your horse either in the evening or early in the morning, whatever is the coolest part of the day. Before putting your horse on the trailer make sure you have opened all the windows and air vents. Get cool air circulating prior to loading. If you have fans on you trailer, turn them on as well.
  • To minimize the impact of heat coming up from the road, place rubber mats on your trailer floor or bed the trailer down with shavings. Heat comes from the sun beating down on the trailer. It also comes up from the black asphalt the trailer is riding on.
  • Hose your horse off prior to loading, in an attempt to keep them cool. Use a fan spray hose head like the Gilmour Fan Watering Wand to make your horse happier.
    By modifying your trailering routine you will be able to ensure your horse travels as comfortable as possible regardless of the weather.

Barn Fan Safety

Each summer horse owners everywhere put fans up in their barns . This helps to cool their horses off as the temperatures rise. However, not all fans are appropriate for barn use. Most horse owners run out to their nearest hardware or discount store to stock up on box fans for their barn.

Before you follow suit, make sure you are buying a fan that is designed for agricultural use. Do not use a box fan designed to be used indoors in a residential situation. Fans (like the Ventamatic 24″ Direct Drive Yellow Tilt & Stand Fan) designed for agricultural use have motors sealed up to prevent dust and dirt from interfering with the motor and starting a fire. In addition to having unsealed motors, inexpensive box fans also have light weight cords which can eventually expose their wiring over time. Take a look at our other barn & horse fans online.

Barn Fires

Barn fires are caused every year from faulty fans and improper installation of fans. To prevent the potential for fires, in addition to only using agricultural fans in the barn, only run fans when there are people in the barn. Turn fans off at night! Most of the time barns are reasonably comfortable at night. Especially if you can open up windows and doors in the barn. Vacuum or blow off dust. Make sure it does not accumulates around the fans that are placed on or in your stalls.

When installing fans, make sure you keep the cords out of the horses’ reach. One bite to a cord can cause a short circuit and potential fire. Remember horses aren’t the only ones to potentially bite the cords, raccoons and mice can also interfere with your cords. Always unplug the fans when not in use!

Another option when it comes to cooling down your barn is to get two large agricultural use approved floor fans. Put them at either end of your barn aisle. These large high power fans do a great job of circulating air throughout the barn during the day.

Enjoy Your Summer

Summer doesn’t have to bring your equestrian activities to a halt. By changing both you and your horse’s riding routine you can both enjoy your summer while staying healthy and competitive. When in doubt whether to ride or go to the pool when temperatures are scorching, play it safe and go for a dip.

Gastric Ulcers in Horses: Facts and Fallacies

Monday, June 30th, 2025

Gastric Ulcers in Horses: Facts and FallaciesGastric Ulcers in Horses: Facts and Fallacies. A recent web-based survey queried horse owners on their knowledge and familiarity with equine gastric ulcer syndrome (EGUS). Based on over 1,100 responses from individuals with and without direct experience with EGUS, here is a summary of what horse owners know, and perhaps more importantly, don’t know about gastric ulcers in horses.

Fact or Fallacy?

Survey respondents indicated that EGUS most commonly occurs in racehorses followed by sport horses. Leisure horses are only rarely affected.

Fact or fallacy? Both, actually. All horses are at risk of developing EGUS, but some horses may have an increased risk based on diet, water intake, lifestyle (use, training level), breed, concomitant diseases, and more.

Horse owners who have prior experience with ulcers were more aware that multiple types of ulcers exist.

Fact. EGUS is an umbrella term that collectively refers to ulcers (erosions in the lining of the stomach wall) that occur in either (1) the squamous or nonglandular region of the stomach, where ulcer presence is called equine squamous gastric disease (ESGD) or (2) the glandular region, where ulcer formation is considered equine glandular gastric disease (EGGD). Some horses can even suffer from EGGD and ESGD simultaneously.

Common Factors:

Low forage intake and infection are the most common factors associated with EGUS by survey respondents.

Fact and fallacy. This is based on a recently published consensus statement on EGUS. Apparently, a high-starch diet is more reliably a predictor of EGUS than low forage intake.

** Those experts wrote that “free access to fibrous feed or frequent forage feeding is widely considered to reduce the risk of gastric ulceration, although strong evidence supporting this belief is also lacking.” That said, to be on the safe side, all horses should get 1.5 to 2% of their body weight in forage daily for overall digestive health and motility. If free-choice access to forage is not suitable for certain horses or is not possible in some management scenarios, horses should go no longer than four or five hours between forage meals.

No specific mention of infection as a risk factor for EGUS was discussed in the consensus statement. Infection causing decreased feed intake, delayed gastric emptying, or stress could potentially contribute to the development of gastric ulcers. Helicobacter pylori infection does not cause ulcers in horses, as it does in humans. The latest consensus statement on EGUS clearly states that antibiotic administration is not justified.

Identifying Ulcers:

Reliable signs of gastric ulceration identified by horse owners included change in behavior when fed, aggression, anemia, low white blood cell counts, and changes in behavior when ridden. Interestingly, respondents with prior experience felt that clinical signs could effectively diagnose EGUS, whereas individuals with no direct experience felt clinical signs were only moderately effective at diagnosing the condition.

Fact. As described by the EGUS expert panel, “Gastric ulcers have been loosely associated with a range of clinical signs in adult horses, despite a paucity of strong epidemiological evidence to support these associations.”

Such clinical signs include decreased appetite, poor body condition, weight loss, chronic diarrhea, poor coat condition, grinding teeth, behavioral changes, acute or recurrent colic, and poor performance.

The best method of diagnosing EGUS by a veterinarian is gastroscopy.

Fact. The expert panel wrote that, because EGUS is poorly associated with clinical signs, “the committee therefore does not support the practice of diagnosing EGUS based on ‘characteristic’ clinical signs and recommends that EGUS be confirmed by performing gastroscopy.”

Effective Treatment?

Both groups of respondents recognized omeprazole as an effective treatment.

Fact. Omeprazole blocks the production of gastric acid (hydrogen chloride) and increases the pH of the fluid in the stomach. This is in line with human ulcer treatments where the adage “no acid, no ulcer” is widely embraced. For examole, the horse should undergo follow-up gastroscopy prior to discontinuing treatment to ensure full healing. This is particularly true for EGGD because resolution takes longer than ESGD.

Sucralfate was recognized as another effective treatment by individuals with prior experience with EGUS but was unknown by those without experience.

Fact. According to experts, sucralfate should be used in conjunction with omeprazole to treat EGUS. The recommended dose is 12 mg/kg orally twice daily for 8 weeks. Overall, the proposed mechanisms of action of sucralfate include: adhering to ulcerated mucosa to protect damaged, healing tissues; stimulating mucous secretion and prostaglandin E synthesis, both of which protect the lining of the stomach); and enhancing blood flow. In Australia, horse owners should look for the sucralfate supplement Sucralox.

In Conclusion:

“A great deal of information regarding EGUS has been uncovered in the past 20 years. Failing to quickly identify EGUS in horses or inappropriately managing horses with EGUS and without the support of their veterinarian will delay appropriate treatment and potentially culminate in adverse outcomes,” said Catherine Whitehouse, M.S., a Kentucky Equine Research nutrition advisor. “Once a veterinarian has diagnosed EGUS, omeprazole treatment should be implemented.”

Summer Pasture-Associated Heaves

Sunday, June 15th, 2025

Summer Pasture-Associated HeavesSummer Pasture-Associated Heaves: Most horse owners have heard of heaves. It’s an asthma-like condition caused by irritation of the respiratory system when dust and mold spores are inhaled. Heaves is most often found in horses that spend a lot of time in stalls. They come in contact with fine particles contained in hay.

Combined with irritating ammonia fumes from wet bedding, these particles cause tissues in the respiratory passages to swell, making it more difficult for horses to breathe. The name “heaves” comes from the audible wheeze and contraction of the horse’s flank as it struggles to move air out of its lungs.

Horses with heaves usually have a normal body temperature and may show a thin, clear nasal discharge. Some heavey horses exhibit worse signs in winter when they are confined to the barn, improving when they are turned out in milder weather.

Summer pasture-associated heaves:

Summer pasture-associated heaves, on the other hand, affects turned-out horses that are sensitive to pollens and molds found in pastures. Signs of illness are the same between the two conditions, but the triggering factor is different. These horses may be more comfortable if they are kept indoors during the warmer seasons.

A nutritional supplement that has gained widespread attention in the fight against heaves is omega-3 fatty acids. They have well-known anti-inflammatory properties. Fish oils are direct sources of DHA and EPA. They are the most useful omega-3 fatty acids in terms of conferring health benefits. Other oils may contain ALA, which must then be converted to DHA and EPA, a complicated and inefficient process. For optimal omega-3 supplementation, use a marine-derived source such as EO-3.

Owners should contact a veterinarian for a diagnosis and treatment program if their horses have trouble breathing or become exercise intolerant during any season of the year.

The Most Profitable Summer Hay Crops in Georgia

Tuesday, June 3rd, 2025

The Most Profitable Summer Hay Crops in GeorgiaThe Most Profitable Summer Hay Crops in Georgia: Our warm summers and fertile soil make it an ideal location to grow a variety of hay crops. For farmers and agricultural enthusiasts, choosing the right forage during the summer can mean the difference between a good growing season and a truly profitable one. J & J Hay Farms is available for all your hay knowledge and needs!

But when it comes to hay, it’s not just about yields—it’s about safety, nutrition, and market appeal, particularly for horse owners and livestock farmers. This blog explores the top warm-season grasses that thrive in Georgia, focusing on those that are both horse-safe and highly profitable. Whether you’re already in the hay business or looking to diversify, here’s what you need to know.

Why Choose Summer Hay in Georgia

When summer arrives, warm-season grasses take center stage. These grasses are adapted to Georgia’s high-temperature conditions and offer hearty yields during the hottest months of the year. Unlike cool-season grasses that may struggle in peak summer, these varieties grow rapidly, making them a staple for farmers looking to maximize productivity through efficient crop cycles.

Additionally, with Georgia’s growing equestrian industry and a high demand for livestock feed, summer hay crops can generate significant profit when managed properly. However, not all grasses are created equal—choosing the right species matters when appealing to the horse feed market or for general livestock nutrition.

5 Types of Warm-Season Grasses Perfect for Georgia

1. Bermudagrass

The Gold Standard of Southern Hay

Bermudagrass is hands down one of the most popular and productive hay crops in Georgia. This warm-season perennial thrives in temperatures typical of the state’s summer months and is known for its durability and high yield. Types such as Coastal, Tifton 85, and Russell Bermudagrass have excellent forage quality.

Why It’s Profitable

  • High Yields: Bermudagrass can produce up to 5-7 tons of hay per acre with proper fertilization.
  • Market Demand: Highly sought after for horse owners and cattle farmers due to its digestibility and nutrient profile.
  • Regrowth Capabilities: Once harvested, it can regrow quickly, allowing for multiple cuts within a single summer.

Considerations for Success

To get the most profit from Bermudagrass, regular soil testing and proper fertilization are essential. Overgrazing can also reduce yields, so rotational cropping practices are recommended.

2. Bahiagrass

Low Maintenance, High Return

If you’re looking for a hardy option that requires less babysitting, Bahiagrass might be your best bet. While not as nutrient-dense as Bermudagrass, it makes up for this with its exceptional drought tolerance, particularly in southern parts of Georgia where water availability varies.

Why It’s Profitable

  • Low Input Costs: Bahiagrass grows well with minimal fertilization, saving money.
  • Hardy Nature: It can withstand heavier grazing or less-than-ideal conditions.
  • Resilient Storage: Once baled, this hay retains quality when stored for long periods, making it a safe investment for fluctuating market conditions.

For farmers targeting livestock rather than horses, Bahiagrass can generate steady income without the steep costs of high-input crops.

3. Alfalfa (Warm-Season Growth Management)

The Premium Crop

Although Alfalfa is traditionally a cool-season crop, modern agricultural practices and hybrid cultivars allow it to thrive during Georgia’s summer months. Alfalfa is revered for its protein-packed leaves, making it a favorite among horse owners who desire high-quality feed.

Why It’s Profitable

  • Premium Pricing: Alfalfa hay markets command higher prices compared to Bermudagrass or Bahiagrass.
  • Versatility: Ideal for horses, sheep, and goats, offering a wide customer base.
  • Improved Soil Fertility: Alfalfa fixes nitrogen back into the soil, reducing future fertilizer needs for rotations.

Keep in mind that Alfalfa requires careful irrigation and pest management. But the high-value returns make the intensive care well worth it.

4. Teff Grass

The Newcomer Making Waves

Over the last few years, Teff Grass has rapidly gained popularity among Georgia farmers. This warm-season annual is fast-growing, drought-resistant, and ideal as horse-safe forage. Its fine stems and soft texture make it particularly attractive to picky eaters like horses.

Why It’s Profitable

  • Fast Turnaround: Teff can be harvested just 45-50 days after planting.
  • Flexible Harvesting: Ideal for farmers looking to supplement their hay inventory or diversify market offerings during peak seasons.
  • Low Inputs/High Output: It thrives with minimal fertilization in well-drained soils.

Teff Grass also appeals to organic and sustainability-minded customers, adding further value to your operation’s overall branding.

5. Pearl Millet

High Tonnage Powerhouse

Pearl Millet is another warm-season annual that packs a punch in terms of both yield and resilience. Its adaptability to sandy or less fertile soils makes it particularly suited for areas across Georgia where traditional crops might underperform.

Why It’s Profitable

  • Impressive Yields: Pearl Millet can generate up to 5 tons of hay per acre.
  • Safe for Horses: Unlike some other crops, it does not produce prussic acid, which can be toxic to horses.
  • Great for Multi-Cutting: Once harvested, it regrows quickly, offering multiple cuts in one season.

Be mindful of over-fertilization, which can lead to nitrate accumulation. Control this with soil testing.

Best Practices for Profitable Hay Production in Georgia

Regardless of the hay type you choose, following these general guidelines will ensure maximum yield and profitability.

  1. Conduct Soil Testing: Understand your soil’s specific nutrient needs to avoid wasteful or excessive fertilization.
  2. Invest in Proper Irrigation: While many warm-season grasses are drought-tolerant, well-timed irrigation can boost yields significantly.
  3. Optimize Cutting Timing: For the highest nutritional value, time your hay cutting right before grasses flower.
  4. Store Hay Properly: Use well-ventilated, waterproof storage spaces to preserve bales from mold and spoilage.

Cater to the Horse Market

Given that horses are particularly common among Georgia’s agricultural customers, focusing your hay production on horse-safe crops like Bermudagrass, Teff Grass, or Alfalfa can be a strategic decision. Consider marketing directly to local horse owners or equestrian centers in your area to secure steady, high-margin sales.

Your Next Steps

By selecting the right warm-season grasses and implementing best practices, you can set yourself up for a profitable summer and beyond. Diversifying crops with the The Most Profitable Summer Hay Crops in Georgia and catering to niche but growing markets—like equestrian enthusiasts—could further increase your success.

Selecting Forages for Horses Diagnosed with Equine Asthma

Friday, May 30th, 2025

Selecting Forages for Horses Diagnosed with Equine AsthmaSelecting Forages for Horses Diagnosed with Equine Asthma: Environmental management is one of the most important aspects of treating and managing horses diagnosed with equine asthma. Asthma is a chronic condition that requires lifelong management changes to maintain respiratory function and overall health. Reducing exposure to respirable antigens, which are the inhaled molds, endotoxins, and other foreign matter that trigger immune response, can help alleviate the clinical symptoms of asthma. The most common respirable antigens in a horse’s environment come from hay, bedding, and potentially pasture.

For horses diagnosed with barn-associated asthma, full-time pasture access is generally recommended. However, this is not an option for many horse owners, and hay is often the primary source of forage. Hay is a major concern for horses with asthma, as hay will always contain some respirable antigens. To reduce the amount of potential inhalation of dust and mold spores, several options are available to the horse owner.

Harm Reduction:

  1. Always ensure the hay is as clean as possible. Only use high-quality hay, as free as possible from dust and mold.

    RDC:

  2. Research has shown that immersing, soaking, or steaming hay before feeding can significantly reduce the number of particles inhaled by the horse. Simply sprinkling the hay with water is inadequate. The hay must be completely immersed and wet throughout to reduce the respirable dust concentration (RDC). One research study found that immersing and thoroughly wetting hay more than halved the mean and maximum RDC in a horse’s breathing zone (the two-foot sphere around the horse’s nose). Other studies have evaluated soaked hay for asthmatic horses. They determined that 30-45 minutes of soaking is adequate to reduce RDC. Longer soaking provides no additional advantages. Horse owners must keep in mind that soaking hay reduces nutrient content. Steaming hay is effective at reducing respirable antigens with less potential for loss of nutrients. However, it is not a viable option for many horse owners. The choice of whether to immerse, soak, or steam hay may best be addressed by the options available to the owner and the horse’s symptoms. If immersing the hay is adequate to eliminate symptoms (usually coughing is the initial and recurring symptom), then that would be the simplest solution. Some research data indicate that feeding soaked hay or hay pellets helps improve lung function. The same study has not been performed using immersed hay.
  3. Remove any uneaten immersed, soaked, or steamed hay from the horse’s reach before it has a chance to generate mold.

    Different Types of Asthma:

  4. For horses with severe asthma, entirely replace long-stemmed hay with pelleted hay or forage replacement, or a complete feed designed to provide adequate fiber to replace dietary forage. Particularly if clinical symptoms persist. Wetting pelleted hay will further reduce respirable particles and may allow the respiratory tract inflammation to subside. However, horses will consume pelleted forages more rapidly and with less chewing than long-stemmed forage. So the best practice would be to feed smaller quantities more often throughout the day.
  5. For horses diagnosed with pasture-associated asthma, the primary causes of respiratory inflammation are certain molds and pollens. They can be present in pastures during growing seasons, particularly during periods of high heat and humidity. Management in such situations includes removing affected horses from pasture during high-risk periods. Such horses usually do best when only allowed pasture access during the winter. During the periods that these horses are kept off pasture, some do require the same forage management as horses diagnosed with barn-associated asthma.

For all horses diagnosed with asthma, decreasing dust in the horse’s environment through ventilation, low-dust bedding, and careful attention to periods of high environmental dust (sweeping barn aisles, high wind, etc.), is recommended.

One additional suggestion for managing horses with equine asthma includes dietary supplementation to help control chronic inflammation. Marine-derived sources of omega-3 fatty acids have been shown to support immune response in horses, including mediation of inflammation.

Steamed Hay for Horses: Protein Content Examined

Friday, May 16th, 2025

Horses eating haySteamed Hay for Horses: Protein Content Examined. 

Steamed hay benefits horses with airway disease by reducing respirable particles. High-temperature steaming, however, damages protein in hay and reduces its digestibility.

“While advantageous for respiratory health, steamed hay may not have ideal protein and amino acid content for some horses. Particularly for broodmares, growing horses, and performance horses,” said Catherine Whitehouse, M.S., a nutrition advisor for Kentucky Equine Research.

Steaming hay, particularly low-quality forage, reliably reduces the microorganisms (e.g., bacteria), dust, mold spores, and other respirable particles that contribute to inflammatory airway disease/equine asthma. Approximately 60% of horses are affected with mild/moderate asthma, and an additional 10-15% suffer severe asthma, giving this disease welfare and economic importance.

Previous studies support using steamed hay for reducing respirable particles but noted that various nutrients and minerals are leached from the hay during the process. A group of German researchers conducted a study to further evaluate the effect of high-temperature steaming on protein and amino acid levels.*

The Science:

Samples of hay were collected and processed using a commercial steamer according to the manufacturer’s instructions. Average temperature during the steaming process was about 206° F (97° C). Nutrients were quantified using standard laboratory techniques, including prececal digestibility of crude protein and amino acids.

“Prececal digestibility is a measure of nutrients digested enzymatically in the small intestine. Proteins that are digested prececally are readily available to the horse and are considered high-quality protein sources,” explained Whitehouse.

Compounds called “Maillard reaction products,” indicators of heat damage to proteins, were also measured.

This study found that while crude protein levels (i.e., a measure of total nitrogen) remained stable in steamed hay, insoluble crude protein did not, resulting in increased protein that is not available prececally.

“These changes were presumed to be due to heat damage to the proteins in the hay,” Whitehouse said. Maillard reaction products were also increased, confirming heat damage.

Finally, the soluble fractions of crude protein declined, decreasing prececal protein digestibility and prececal digestibility of specific amino acids, including lysine, a limiting amino acid, and sulfur-containing amino acids.

“Amino acids are the building blocks of muscle, skin, and hooves. When diets fall short of these essential amino acids, changes in hair coat, topline, immunity, and overall health may be noticed,” Whitehouse said.

In sum, despite decreased availability of protein and amino acids, steaming remains a recommended practice because of the reduction in respirable particles.

How to Address Shortfalls:

How do horse owners address this shortfall?

“We simply need to take into consideration these losses and supplement the diet appropriately to ensure it is balanced and supplying adequate levels of amino acids. High-quality protein sources, such as soybean meal, alfalfa, and peas, can be added to boost protein levels and amino acids. These plant-based proteins are used in well-formulated horse feeds and ration balancers,” Whitehouse said.

Benefits of Integrating Warm-Season Grasses into Pastures

Thursday, May 8th, 2025

Benefits of Integrating Warm-Season Grasses into PasturesBenefits of Integrating Warm-Season Grasses into Pastures: Warm-season grasses help minimize the “summer slump” in pastures dominated by cool-season grasses such as tall fescue, orchardgrass, and Kentucky bluegrass. Specifically, warm-season grasses like Bermuda grass and crabgrass improve pasture yield in hot, dry months. Research by Rutgers University identified two additional benefits of warm-season grasses. (1) creation of desirable forage composition for certain horses, and (2) beneficial shifts in the equine intestinal microbiome.*

For the study, researchers followed eight metabolically normal mares (i.e., no evidence of insulin dysregulation or equine metabolic syndrome) during a single grazing season. They grazed cool-season pasture in the spring and fall. Then, warm-season pasture in the summer. Fecal samples were collected throughout the grazing season after adapting to each diet.

First Benefit:

As to the first benefit, warm-season grasses are lower in nonstructural carbohydrates (NSC) and water-soluble carbohydrates (WSC). The NSCs are composed of starch and WSCs, which are simple sugars such as glucose and fructose, among others.

Forage analysis of both warm- and cool-season grasses used in this study were similar to previous reports in that warm-season grasses had markedly lower NSCs and WSCs than cool-season grasses.

“Pastures naturally lower in nonstructural carbohydrates are particularly important for horses with insulin dysregulation because higher levels of NSCs can challenge a horse’s metabolism,” said Kathleen Crandell, Ph.D., a Kentucky Equine Research nutritionist.

According to Crandell, when excess sugars and starches are consumed, they increase blood glucose (sugar) levels, triggering the release of insulin from the pancreas. Insulin prompts the body’s tissues to take up the glucose for metabolic purposes.

“With insulin dysregulation, the glucose is not responsive to insulin’s drive to push it into the cells. This causes more insulin to be released. The horse ends up with prolonged high insulin levels in the blood. These high levels of both glucose and insulin in circulation can have detrimental effects on various metabolic functions in the body. They can potentially result in hyperinsulinemia-associated laminitis,” she explained.

Minimize Glucose Levels:

To help minimize the persistently elevated levels of circulating glucose after a meal, diets low in NSCs are recommended for horses diagnosed with insulin dysregulation or equine metabolic syndrome. With a lower NSC content, this makes the warm-season grasses desirable.

The cool-season grasses were higher in NSCs than the warm-season grasses. However, none of the horses participating in this study had abnormal results from an oral sugar test administered periodically throughout the study. The oral sugar test measures a horse’s insulin response to a sugar challenge. It is a key test used to diagnose insulin dysregulation. The researchers stated, however, the study may not have been long enough in duration to pick up on subtle changes in insulin sensitivity between horses fed warm- and cool-season grasses.

Second Benefit:

The second advantage includes microbiome shifts in response to feeding warm-season grasses.

According to the researchers, “Distinct shifts in equine fecal microbial community structure and composition occur as horses adapt to different forages within an integrated warm- and cool-season grass rotational pasture system.”

While several alterations in the intestinal microbiome were observed, one notable change was enrichment with Clostridium butyricum when consuming warm-season grasses. This bacterium is a well-known producer of butyrate, a short-chain fatty acid (volatile fatty acid).

“Butyrate promotes anti-inflammatory responses. It improves the gastrointestinal barrier to mitigate ‘leaky gut syndrome.’ It also plays a role in improving metabolic health,” Crandell explained.

“In summary, this study shows distinct benefits of feeding warm-season grasses in the summer months. For example, improved pasture yield; lower nonstructural carbohydrate levels; and enrichment in beneficial bacteria in the intestinal microbiome, specifically C. butyricum,” said Crandell.

Even with integration of warm-season grasses, all horses still benefit from a salt supplement. In addition, a high-quality vitamin and mineral supplementation to balance out the nutrients that may be low or missing in the forage.\

Managing Feed for Weanling and Yearling Horses

Friday, April 25th, 2025

Managing Feed for Weanling and Yearling Horses : Photo of a young horse standing in a green pastureManaging Feed for Weanling and Yearling Horses: Young horses need good-quality feeds to meet their nutrient requirements for growth. In addition, free-choice exercise in large paddocks. Weanlings and yearlings have high requirements for energy, protein, amino acids and minerals in order to grow optimally. If you are using a commercial mixed feed, make sure it is formulated for the growing horse.

Energy

Oats are often the cheapest source of energy for young horses. They are best fed crushed to weanlings because their teeth are not fully developed and they will have trouble breaking open whole grains. Steam flaked maize (corn), barley and lupins are other grains that are good sources of energy for the growing horse. Lupins also have high protein levels. Adding fat is a safe way to rapidly condition your young horse. You can use oil, sunflower seeds, stabilised rice bran or a higher fat prepared feed. A general rule of thumb is to provide 1 kg of fortified grain per 100 kg of body weight, up to a maximum of 3 kg/day per weanling. Good doers such as warmbloods, quarter horses and ponies may get fat on these concentrate feed intakes! They do better on a low intake feed balancer pellet or a more concentrated breeding feed.

Protein

Weanlings need approximately 15% crude protein and yearlings need 13% crude protein in the diet along with adequate intakes of essential amino acids such as lysine to maintain optimum growth. Young green grass or clover pasture contains 15–20% crude protein. However this amount falls rapidly as the plants begin flowering and start to seed. Dry summer or winter pasture often contains very little protein, so yearlings will need supplementation. Young horses need high-quality protein that contains all the essential amino acids, especially lysine. Animal-derived proteins such as milk powder are of very high quality but are expensive, and soybean meal is the best-quality vegetable protein. Canola meal is also a good quality protein source. Legumes such as lucerne and clover also have a high level of good quality protein. Linseed meal is relatively low in lysine and is not a good source of protein for growing horses, although its high oil content will produce a bloom on the coat.

Vitamins and Minerals

Calcium and phosphorus are the most important minerals for growing horses. Grains are low in calcium, whereas lucerne, clover hays and high-quality pasture contain more calcium. However winter and spring pastures may unexpectedly contain ration inversions of calcium to phosphorus. Bran contains a lot of phosphorus and should not be fed in significant quantities to growing horses. Urinalysis can be used to assess the calcium status of young horses. The calcium to phosphorus balance of the ration can be analysed by an equine nutritionist.

Young horses running in a paddock can lose 30 g of salt per day in their sweat and urine, especially during hot weather, so provide a salt block or supply a salt supplement.

Trace minerals such as copper, zinc, manganese, and selenium are important components in the diet for most growing horses. They need to be supplied in the right quantities and ratios in commercial feeds formulated for young horses.

Roughage

To meet the commercial growth requirements of young horses, you may have to feed them less roughage than desired for optimal digestive function. Therefore, you must use good-quality chaff or hay to maximize the utilization of the fibrous feed in meeting the energy requirements. Also decrease the amount of starch the weanling has to be fed. High-quality, early-cut hay will also minimize the pot-belly appearance caused by fibre and water in the gut, a situation often associated with mature hay with high lignin content. Lucerne or clover hay will also supply higher intakes of protein and calcium as well as fibre. They are often preferred for growing horses. As the horse gets older it eats more, so you can switch from a legume hay to a grass or oaten based hay. This is true particularly during spring when they have access to green grass.

Choice of Feed

If you have great quality pasture or are feeding breeds with a good metabolism, such as warmbloods, quarter horses, draught breeds or ponies, a feed balancer pellet or a concentrate  is often the best approach.

Remember to monitor growth, legs and body condition carefully. Adjust feed intake or choice of feed in order to maintain optimum growth for each individual weanling and yearling.

Use of Cover Crops in Horse Pastures

Tuesday, April 15th, 2025


Cover CropsUse of Cover Crops in Horse Pastures:

Though it is still only late spring, consider cover crops ahead of time. Many farms plant them in the late summer or early fall. They provide protective ground cover during the winter. The crops are then grazed, harvested, or tilled into the soil in the spring. In addition to erosion control and protection of water quality, cover crops have favorable effects on soil structure, weed suppression, and biodiversity. The use of cover crops on horse operations has not been studied until recently. Researchers in the Midwestern United States evaluated several cover crop forages in pastures specifically intended for horses.*

Depending on the plant species, cover crops offer various, and oftentimes specific, benefits. Annual ryegrass and winter have many uses. For example, their high germination rates, ease of establishment, and efficiency in covering barren soil, all of which foster weed suppression and forage output. The nitrogen fixation properties of legumes, like berseem clover, boost soil fertility. Taproot species, such as purple top turnip and daikon radish, loosen shallow layers of compacted soil. In addition, they scavenge residual nitrogen. Leaching may have taken it. The channels created by the growing taproot, a process called “biodrilling,” allow other pasture plants to more easily access soil nutrients and moisture.

Horse Owner Perks:

In addition to soil and environmental advantages, cover crops offer a particular perk to horse owners. They can prolong the grazing season and reduce the reliance on preserved forages, particularly hay, in the late fall. In years when hay is expensive or in short supply, this may prove advantageous.

The objectives of this study were to evaluate forage mass, forage nutrient composition, and preference of annual ryegrass, winter rye, berseem clover, purple top turnip, and daikon radish by horses. Forage mass is the total dry weight of forage per unit of land.

Four mature mares grazed seeded-singularly-or-as-mixtures-cover-crops for two consecutive fall seasons. Prior to grazing, forages were sampled to determine forage mass, root mass, and nutrient composition. To estimate preference after grazing, forages were visually assessed by researchers for the percentage of removal on a scale of 0 (no grazing activity) to 100% (all available forage grazed).

Berseem clover was the lowest producing forage. Minimal differences existed among the other cover crops. Horses preferred the berseem clover. The preferred turnip and radish least. Winter rye and annual ryegrass in monoculture and when seeded with berseem clover were moderately preferred (20%–68% removal). These species also met the digestible energy and crude protein needs of sedentary mature horses. However, the calcium-to-phosphorus ratio was inverted.

In Conclusion:

According to the researchers, “placing a priority on preference, berseem clover, annual ryegrass, and winter rye appear to be suitable cover crops to extend the grazing season in horse pastures.”

“While grazing pastures may seem the most natural of feeding systems for horses, health concerns can make grazing specific plants dangerous for certain horses,” noted Catherine Whitehouse, M.S., a nutritionist for Kentucky Equine Research. “When planning any upgrade to a grazing area, consider the horses that will eventually graze it. Select proper forages for horses predisposed to laminitis or other metabolic challenges. Consider their needs and long-term well-being.” Limit grazing to certain times of the day.
