Feeding Horses Hay Before Grain Meals

Thursday, March 17th, 2022

Feeding Horses HayFeeding Horses Hay Before Grain Meals: Concentrates perfectly complement a forage-based ration when they are fed according to the manufacturer’s recommendations. When horses rapidly consume large amounts of concentrates, beyond the meal size recommended by the manufacturer, negative effects on overall health can occur.

“Ingestion of high levels of nonstructural carbohydrates (NSC) decreases the acidity of the hindgut. Subsequently, due to rapid fermentation of the NSC. In addition, the pro-inflammatory mediator interleukin-1β increases in a horse’s bloodstream within an hour of a starchy, sugary meal,” explained Kathleen Crandell, Ph.D., a Kentucky Equine Research nutritionist.

Higher than normal circulating interleukin (IL)-1β levels are believed to have negative effects on overall health. For example, contributing to the development of laminitis.

In the last two decades, nutritionists have brought forth feeding strategies that fulfill energy requirements and keep the gastrointestinal tract functioning glitch-free. For instance, some concentrates feature multiple energy sources. In addition to starch, these energy sources include “super fibers” such as beet pulp and soy hulls, and fat from oil or stabilized rice bran. Horses with high energy requirements typically do well on these feeds.

Offer nutritional supplements also. They’re designed to maintain a stable pH in the hindgut.

According to Experts:

Recently, one veterinary research team found that offering a small amount of hay immediately before feeding a meal containing a moderate amount of starch or sugar can reduce the negative effects of rapid starch and sugar fermentation in the equine digestive tract.*

Crandell added, “According to those experts, as little as 2 lb (0.9 kg) of hay—a small flake—can decrease IL-1β levels in the bloodstream. This happens for up to 8 hours after offering concentrate. In other words, the inflammatory response to dietary concentrates can be blunted by hay.”

Offer concentrates in several small meals throughout the day. However, usually no more than 5 lb (2.3 kg) in a single feeding.

Feeding Low-Carbohydrate Hay or Straw to Obese Horses

Thursday, March 10th, 2022

Feeding Low-Carbohydrate Hay or Straw to Obese Horses: The excess weight carried by obese horses may be an indication of an “easy keeper” metabolism. As a result, the heavy load can eventually take a toll on weight-bearing joints. In other cases, the bulging fat pads and cresty neck could be signs of metabolic diseases that put the obese horse at increased risk for laminitis. Either way, owners of overweight horses are often advised to work toward weight loss in their equines. This usually involves increasing the horse’s exercise level, eliminating grain, restricting grazing time, and feeding a low-carbohydrate source of fiber.

In managing an obese horse, the owner faces a dilemma. If the horse is lame or out of shape, it’s hard to add enough exercise to make a difference. Cutting grain from the diet is fairly simple, and a drylot or grazing muzzle can help with restricting pasture intake. However, horses that spend hours with an empty stomach are prime candidates for gastric ulcers. As a result, they need to have something to nibble on a fairly constant basis. Finding a low-carbohydrate hay may not be easy.

Straw:

Some horse owners wonder if straw—the slippery, shiny stems of wheat, oats, and other cereal plants—might be the answer. After all, straw is usually used for bedding so it can’t be worth much in the way of nutrition, right?

Unfortunately, some straw, particularly if it contains many of the grain seed heads, can be as high in nonstructural carbohydrates as good-quality grass hay or even alfalfa hay. Though it contains a lot of lignin, the indigestible fiber that causes its shiny appearance, straw may also contain an appreciable amount of digestible starch and carbohydrates. The only way to know these levels is to have the straw analyzed for nutritional value. Above all, as any type of hay should be tested before feeding it to obese horses. It’s not enough to get a base level from one shipment of hay or straw, either. The next truckload you order will probably be from a different cutting or region. Therefore, it will have different nutritional values.

Impaction:

Even if it’s possible to find a low-carbohydrate straw, there’s another potential problem with feeding this form of roughage. Because of its high proportion of indigestible fiber, straw is more likely than hay to cause impaction, a condition in which ingested material stops moving through the digestive tract and forms a blockage. This is particularly common in winter. Horses may not drink enough water to keep the intestinal tissues lubricated and elastic. Impaction colic is more of a risk for horses on a diet of straw or any other type of tough, stemmy forage. Chopping the straw into short pieces before feeding it may help to avoid this problem. Especially for horses whose teeth are not in perfect condition for chewing.

Because it may provide a significant level of calories while presenting a hazard for choke or impaction, straw isn’t a great forage choice for most horses. It’s probably safer to find and feed a low-carbohydrate hay, soaking it before feeding to remove some water-soluble carbohydrates. Testing hay is relatively inexpensive and can support health in horses and peace of mind in their owners.

Watch Out For Toxic Plants in Hays, Pastures

Thursday, February 24th, 2022

Watch Out For Toxic Plants in Hays, PasturesWatch Out For Toxic Plants in Hays, Pastures: Aren’t horses smart enough to know what they can and cannot eat?

Generally speaking, it is true that horses will usually avoid ingesting harmful plants or other toxins when offered high-quality forage options. But as highlighted in an article* by veterinarians from the Department of Veterinary Clinical Sciences at Oklahoma State University, horses can—and often do—consume plants they shouldn’t.

As reviewed in this article, horses were offered Bermuda grass hay that was later found to contain large quantities of mature caley pea (Lathyrus hirsutus). In that case, 22 out of 25 young horses developed signs of intoxication. Signs included incoordination, lethargy, and changes in gait.

“There are a great many toxins that can sneak into bales of legumes and grasses, which highlights the importance of routinely inspecting your horse’s hay for more than just dust and mold,” relays Bryan M. Waldridge, D.V.M., head veterinarian for Kentucky Equine Research.

In addition to classic examples of endophyte-infested tall fescue and blister beetles in alfalfa, owners should familiarize themselves with other toxins in their area. Pastures and paddocks also need to be monitored for toxic plants. For example, trees (e.g., maple, black walnut) and ornamentals (e.g., oleander, foxglove, tulips, daylilies, hydrangea, morning glory, iris, daffodil, etc.).

For information on toxic plants in your area, seek the assistance of an equine extension specialist or plant pathologist. Plant descriptions and photos are available online.

Determining Hay Quality for Horses

Thursday, February 17th, 2022

Determining Hay Quality for HorsesDetermining Hay Quality for Horses:  Hay quality is assessed primarily through on smell, feel, and visual appearance. Generally, hay should be fine-stemmed, green, and leafy. It should have a sweet smell and be free of any mold. Excessively bleached or discolored hay should be avoided. In addition, any that smells musty, dusty, or fermented. Avoid hay with high amounts of weeds, dirt, trash, or debris. In addition, hay with signs of insect infestation.

The presence of seed heads, stem coarseness, and a low leaf-to-stem ratio determine hay maturity. An abundance of leaves generally indicates higher nutrient levels in the hay. However, it is also important that leaves remain intact and do not fall from the stems too easily.

Palatability and the performance of horses being fed the hay somewhat judge quality. However, the ultimate test of quality is laboratory analysis. Kentucky Equine Research (KER) uses the forage laboratory at Dairy One Laboratories in New York for hay testing. International locations accept samples for analysis.

Hay to Feed:

As to what is the best type of hay to feed, there is no simple answer as it depends on what type of horse you have and what nutrients need to be supplied by forage. What is best for a foal or racehorse won’t suit a roly-poly pony, for example. Select hay according to the needs of the particular class of horses such as foals, pregnant mares, competition horses, horses recovering from illness, and so on.

Legume Hays:

Hays like lucerne (alfalfa) and clover have higher levels of energy, protein, and calcium than plain grass hays. Horses with higher requirements for protein and calcium such as growing or breeding horses would benefit from lucerne in their diets, as well as some hard-working performance horses. Endurance horses need diets without excessive protein or calcium, so high energy grass hay such as Teff are ideal. Obese horses usually need low-energy hay, so mature grass hays are best. Any horses with metabolic problems or digestive issues would also benefit from hays that contain lower levels of sugars, and grass hays are ideal for these situations.

Baled Hay:

Hay baled at a high moisture level or hay that has gotten wet in storage may be moldy. Moldy hay will smell musty. It will look damp and dull in color. It may even have patches of white or brown mold that makes the hay clump together. Generally, moldy hay is less palatable for horses. Therefore, reduced intake is the first issue. Mold contains mycotoxins that can cause a number of illnesses including colic in horses. Moldy hay is also dustier than normal hay. This dust contains fungal spores. Horses can inhale. This can irritate the respiratory tract. The irritation can lead to diseases such as heaves or recurrent airway obstruction because the dust causes inflammation in the lungs, increasing respiratory effort and reducing exercise tolerance.

Feeding Preserved Forage to Horses

Thursday, February 10th, 2022

Feeding Preserved Forage to HorsesFeeding Preserved Forage to Horses: If you had the chance to feed your horse better for optimal health, behavior, and performance, what would you do? A recent article addresses the fact that many horses are fed based on historical trends rather than modern conditions.

Equine diets were significantly altered with domestication, according to the authors of the article*. Horses were once recruited as beasts of burden. They were far too busy to graze fresh pasture for the majority of the day. Instead, owners fed oats, barley, beans, and root vegetables to provide sufficient energy for work. Offering preserved forage such as hay was more difficult in those days due to the challenges associated with the distribution and transport of bulky forages in addition to concerns regarding the quality of forage.

Now, many horses continue to receive preserved forages—including hay, haylage, and silage—rather than having access to fresh pasture. Even with the dramatically reduced workload compared to past times, some horses are still fed too many energy-dense feedstuffs (concentrates) and insufficient preserved forage or fresh pasture, despite the availability of quality forage that can often negate the need for excess concentrates.

Recommendations were made in reference to feeding preserved forage based on a comprehensive review of the literature and information garnered during conferences and nutrition workshops.

Recommendations:

  • Perform nutrient analysis to appreciate the value of the forage and estimate the energy content. This is especially true for thin, overweight, and laminitic horses, or those with metabolic conditions.
  • Routinely inspect the hay to ensure no hygiene issues exist (e.g., growth of molds that can negatively impact horse health). Dispose of poor-quality forage.
  • Any substantial changes in forage quality in terms of energy, protein, and water-soluble carbohydrate content requires a two- to three-week acclimation period.
  • Offer fresh or preserved forage with stem length greater than one inch (2.5 cm) ad libitum throughout the day.
  • Horses should be consuming feed (hay or concentrate) for a minimum of 8-10 hours/day, with a maximum of 4-5 hours without food.
  • If a horse requires more energy, use less mature forages.
  • Consider introducing small amounts of chaff into the diet, if less energy is required (maximum of 30% of the dry matter ration).

“Note that these recommendations apply to healthy horses with an ideal body weight and no underlying medical condition. Although these suggestions are useful generalizations, every horse is unique and must be fed individually. Tailor your horse’s diet to meet his needs. For example, consider consulting with one of the nutrition advisors at Kentucky Equine Research,” advised Kathleen Crandell, Ph.D., a nutritionist for KER.

Offer a well-formulated vitamin and mineral supplement. Especially for horses on diets composed entirely of forage.

The Importance of Weighing Feed

Thursday, January 27th, 2022

Feed Horse Hay by Weight, Not by FlakeThe Importance of Weighing Feed: How many times have you had to describe your horse’s ration and found yourself saying, “He gets a scoop of this and a scoop of that”? Most horse owners describe diets this way. However, there are many disadvantages to measuring your horse’s feed amounts in “scoops” rather than weight.

Why Weigh?

To determine dietary requirements, horse characteristics are first considered. These include age, breed, workload, metabolism, and weight. For example, for optimum digestive health each horse requires at least 1% of its body weight in forage every day. That would be at least 5 kg (11 lb) for a 500-kg (1,100-lb) horse. Do you have a horse that is restricted from pasture or has access to very little pasture? It is important to know how much hay he is receiving. Establish if he is receiving adequate forage. This is especially true if you are looking to substitute hay as a forage source

Experienced nutritionists have formulated these in accordance with characteristics of certain classes of horses, including their weight. When looking at fortified feeds. They then recommend a minimum amount of the feed that each type of horse requires to meet its specific nutrient requirements. Based on the formulations.

Therefore, by weighing feeds you know exactly how much your horse is getting daily. In addition, if your horse is receiving a balanced diet and meeting requirements for forage and the nutrients that are important for achieving optimum health, development, and performance.

Weighing feed leads to peace of mind that your horse is meeting its nutrient requirements. Feed costs can be cut often. Determine how much of each feed is required. The need for expensive vitamin and mineral supplements is decreased when a fortified feed is fed at the correct amount daily.

Weight vs. Volume

In any given feed room, you are likely to come across a wide variety of measuring utensils. Open scoops, dippers, ice cream containers, tins, jars, and bowls are commonly used to convey feed to the trough. Each may hold a different volume of feed.

Equine nutrition consultants often hear from horse owners that they use a 1-kg (2.2-lb) scoop. Due to different feeds having different densities, this is hardly accurate. A scoop of chaff has the same volume as the same scoop of pellets or muesli (textured feed). However, the varying densities of these feeds means that they weigh very different amounts. A 2-litre (1/2-gallon) scoop of a pelleted feed may weigh up to 1.5 kg (3 lb), whereas that same 2-litre scoop of lucerne (alfalfa) chaff will weigh much less.

Method of Weighing

Accurately and conveniently feeds may be weighed. Use common types of scales. A hook scale, like those used for weighing fish or luggage, is easily used to weigh hay or haylage. By hanging the haynet or hay bag off the scale. If you’re not using a net or bag, then a bundle of hay may be tied up with twine then hung from the scale.

Feeds may be weighed in a similar manner. Do so by using an empty pail or bag as a receptacle to hang from the scale. Simply fill your scoop with feed or grain and then empty it into the bag before hanging the bag on the scale. In this manner, you can determine the weight of all feedstuffs in each of the scoops you normally use. Be sure to take into account the weight of the bag or net. This is achieved by weighing that first and subtracting this amount from the final reading.

If a flat platform scale is your available weighing device, then weighing feeds and cereals may be accomplished by using the scoop or a pail as a receptacle. First, weigh your scoop or pail and note the weight of the container or press “tare” on the scales if they are electronic. Then, fill the scoop with feed. Weigh again or empty into the pail already on the scale to weigh the contents. The weight displayed should be the weight of only the feed contained within the scoop or pail. For electronic scales with a tare function.

Other Scales:

For other scales, you may have to manually subtract the weight of the container from the total amount of feed and container combined. In order to weigh hay on a platform scale, you may need a larger platform. A piece of rigid cardboard or wood may work well for this. Be sure to zero the scale or note the weight of the platform before placing the hay atop it. Then, simply balance the portion of hay or haylage you wish to measure on the platform and note the weight displayed. Again, this depends on whether or not the scale is electronic. The amount displayed will be the weight of the forage or the forage and platform combined.

Hay and feed shouldn’t require weighing each time you feed your horse. You can simply estimate how many sections of hay your horse requires daily by determining the average weight of a section of each batch of hay you get. Feed amounts can be determined by knowing approximately how much a scoop of each foodstuff in your horse’s diet weighs.

Use of Round Bales for Horses

Thursday, January 20th, 2022

Round Bale Advantages

“Using round bales as part of a feeding system has advantages. They are economical compared to traditional square bales. This is important as hay is commonly the most expensive component in the diets of mature horses,” said Kathleen Crandell, Ph.D., a nutritionist for Kentucky Equine Research. “In addition, round bales are convenient to use. This is especially true when forage must be transported through snowy and ice-covered paddocks in the dead of winter.”

However, round bales should be used appropriately to offset potential drawbacks. This includes loss of nutrients, mold growth, negative effects on the respiratory system, and waste.

“Freeze-thaw cycles may have an effect on certain nutrients, particularly organic nutrients like proteins and fat-soluble vitamins,” explained Crandell. “Other nutrients, like minerals, appear to be fairly stable even if the hay is frozen, just as long as the hay stays dry.”

Once the hay gets wet, forage quality degrades rapidly. Further, when wet hay freezes and thaws, even more damage can occur to the protein found in the hay, particularly if it is a slow thaw.

If hay gets soaked through, there will be some leaching of nutrients and nonstructural carbohydrates, just like when hay is soaked for horses with certain metabolic conditions. Fat-soluble vitamins decline as hay ages, but soaking may intensify losses.

Because of the structure of the round bale, rain does not penetrate into the inner layers. This is especially true if the bale has been tightly bound and laid on its side.

“Mold growth is another factor to consider when hay gets wet and does not dry. Mold not only affects nutrient loss but can also be toxic to the horse,” Crandell advised.

Consumption Advice

Because of the inevitable losses of nutrients, round bales exposed to the elements should be consumed in four to seven days. Depending a bit on the size of the bale (they can vary greatly in weight), four horses can usually consume a bale in this time frame. Be cognizant of each horse’s body condition score when feeding herds, and remember that if there are too many horses trying to eat from one bale there may be a problem with competition.

“When using round bales, feeding a concentrate may be necessary if the hay doesn’t provide sufficient calories for maintenance of body condition. For horses that can maintain weight with hay alone, use a research-formulated vitamin and mineral supplement or ration balancer,” advised Crandell.

Waste from large round bales can be reduced through the use of feeders. Various models are marketed to the horse industry, and dimensions of the feeders vary. Some have roofs to protect hay from precipitation. In one study that compared nine models of round-bale feeders, hay waste ranged from 5% to 33%, while waste when fed with no feeder was measured at 57%.*

Alfalfa and a Healthy Gastric Environment in Horses

Thursday, January 13th, 2022

Alfalfa and a Healthy Gastric Environment in HorsesAlfalfa and a Healthy Gastric Environment in Horses: Experts suggest that feeding alfalfa (lucerne) reduces the incidence and severity of gastric ulcers in the upper region of the stomach, known also as equine squamous gastric disease. Alfalfa hay has a well documented buffering capacity. However, new research shows that horses in heavy work need more than alfalfa to maintain a healthy gastric environment.

About Gastric Health:

In certain circumstances, the pH of the stomach can dip as low as 1 or 2, on the pH scale of 0 to 14. This is more acidic than grapefruit or tomato juice. The lower or glandular region of the stomach produces mucus to protect the lining. The upper or squamous region, however, is far more sensitive to sloshing acid, making it prone to ulceration. All horses are at risk of developing gastric ulcers. For horses involved in training and competition, this condition is particularly prevalent.

Recognizing the widespread welfare and economic effects of equine gastric ulcer syndrome (EGUS), Kentucky Equine Research developed several products to support stomach health. “Some of these products contain ingredients that neutralize excessive gastric acid, protecting the stomach lining by reducing acidity and providing a physical barrier due to coating properties,” said Catherine Whitehouse, M.S., a nutritionist for Kentucky Equine Research.

Altering the diet may also minimize EGUS. Nutritionists suggest:

  • Feeding diets high in fiber (at least 1.5% body weight in forage);
  • Offering stabilized rice bran or vegetable oil rather than high-starch feedstuffs for supplemental energy;
  • Feeding several meals per day when possible; and
  • Using small-hole haynets and slow feeders to make forage last through the night until breakfast.
  • Nutritionists sometimes recommend feeding alfalfa hay to help ward off EGUS. High levels of certain nutrients, including protein and calcium, reportedly help neutralize acid in the stomach.

According to Whitehouse, “The amount of calcium in alfalfa hay is often greater than 1% with a calcium-to-phosphorus ratio ranging from 3:1-6:1, whereas calcium in grass hay hovers around half that with a much tighter calcium-to-phosphorus ratio.”

Horses with high nutritional needs normally receive pure alfalfa hay. It would oversupply energy, protein, and minerals for many horses. “We typically recommend including only a portion of alfalfa in the diet and combining it with a high-quality grass hay,” advised Whitehouse.

According to a recent study:

Alfalfa pellets do not appear to buffer the stomach in heavily exercised horses as effectively as alfalfa hay might. France performed the study. It included 80 trotters from four training centers randomly divided into two groups. Horses in the control group were fed their usual diet of free-choice grass hay and pelleted concentrate. This provided 4.5 ± 1.5 g of starch per kilogram body weight per day. In the alfalfa group, the diet was the same. However, dehydrated alfalfa pellets replaced half of the pelleted concentrate. Thus providing only 2.3 ± 0.7 g of starch per kilogram body weight per day.

All horses were examined via gastroscopy. In order to to directly visualize the lining of the stomach. Ulcer scores were assigned on days 0, 21, and 42 based on a scale of 0 to 4, with 4 denoting severe ulceration. Throughout the study period no other changes in management or training were made.

At baseline (day 0), 49 of the 80 (61%) horses had either no lesions or mild ulcerations, equivalent to an EGUS score of 0, 1, or 2. The remaining 31 horses (39%) had severe EGUS with scores of 3 and 4. No significant effect of the diet on either healing or prevention of EGUS was detected at days 21 and 42.

In Conclusion:

Researchers theorized that alfalfa pellets did not provide a protective layer on top of the gastric contents as alfalfa hay or chaff does. Chaff is believed to prevent splashing of acidic gastric contents on the sensitive squamous lining of the stomach. Giving some alfalfa hay or chaff before exercise will help buffer the acid and prevent damaging acid splash in the squamous part of the stomach. Additional protection may be provided. For example, by adding a research-proven gastric buffer, such as Triacton, to a small meal 30 minutes before work.

Feeding Horses: Don’t Miss the Forage for the Feed

Thursday, January 6th, 2022

Feeding Horses: Don’t Miss the Forage for the FeedFeeding Horses: Don’t Miss the Forage for the Feed. Conscientious horse owners know the importance of forage. That is why many hours are spent selecting hay and caring for paddocks, pastures, and other grazing areas. In addition to forage, most horses require the nutrients found in a concentrate for optimal well-being. As a result, that concentrate is often chosen based on the forage available.

When available, how much fresh forage will a horse or pony consume?

Before we can answer this question, a horse’s total recommended feed consumption (forage and concentrate) must be known. Most healthy mature horses in moderate body weight should consume about 1.5-2% of their body weight daily. Some horses with higher energy requirements may consume as much as 2.5% of their body weight daily.

If a mature Arabian mare weighs 1,000 lb (450 kg), for example, 1.5-2% of her body weight equates to 15-20 lb (7-9 kg) of forage and concentrate combined a day. Firslty, how much of the total is forage? Secondly, how much is concentrate depends on the individual horse (age, metabolism, workload, etc.)? For most horses, the forage fraction of the diet will contribute at least 50% of daily intake but usually far more.

Forage requirements can be met through pasture, hay, and hay products, such as cubes and pellets. The contribution of pasture to a horse or pony’s nutritional requirements should not be underestimated. When given 24-hour access to pasture, mature horses may consume 2-3% of their body weight per day; adult ponies may consume 3-4% of their body weight per day but sometimes more. Mature horses and ponies can therefore satisfy their total feed requirement. Vitamin and mineral supplementation, from full-day turnout on good-quality pasture, is the exception.

What if horses are turned out for only a few hours a day? Horses are likely to consume 0.4% of their body weight for every three hours of turnout with 1-2% of body weight for full-daytime turnout. Double these values for ponies.

Many horses are offered a mixture of pasture and hay each day. With this in mind, how much hay do you offer a horse that also consumes pasture? That depends how long the horse grazes. While every horse is an individual, here’s a starting point:

  • Is your horse allowed four to eight hours of turnout on pasture? He will fulfill 25-50% of his forage requirement and will need 50-75% of his required forage when stabled.
  • Is your horse allowed eight to twelve hours of turnout on pasture? He will fulfill 50-75% of his forage requirement and will need 25-50% of his required forage when stabled.

Other factors may influence the amount of forage fed, notably caloric requirements as determined by body condition. For easy keepers, it might be necessary to use a grazing muzzle during turnout and provide a clean, mature grass hay to satisfy the majority of his forage requirement. To draw out the time it takes to consume the hay, a slow-feed haynet or similar device can be used. For the hard keeper or intensely worked athlete, free-choice access to pasture and a legume or legume-grass mix might be necessary to maintain moderate body condition.

Here’s a real-world example:

Feeding HorsesThis is Griffith, a four-year-old appendix-bred Quarter Horse gelding. He stands 16.2 (168 cm) and currently weighs 1,260 lb (574 kg).

Before arriving at his new farm, he was turned out 24/7 on average pasture with no concentrate, and he maintained his current body condition. The new boarding stable has high-quality pasture but does not offer all-day turnout. Instead, Griffith will graze four hours and will spend the remainder of his day in a stall.

He will be ridden five days a week, lightly to moderately, in preparation to become a show hunter. With hay in short supply, the barn owners want to ensure he has enough forage to fuel his work without overfeeding. Plus, excessive body condition may cause him to gain weight and place unnecessary stress on immature joints as he learns to jump. Where do you begin?

When considering forage requirements for Griffith, two things come to mind immediately: (1) he is fairly young and potentially has more growing to do, even if only a bit; and (2) he is in light to moderate work.

To fuel these two physiological endeavors and meet maintenance requirements, let’s estimate that he will consume 2% of his body weight per day in forage and concentrate combined. As stated above, if he is allowed to graze four hours on high-quality pasture, we can assume that 25-50% of his forage requirement, or 0.5-1% of body weight, will be satisfied through grazing. That leaves a balance of 1-1.5% of body weight that must be provided in hay. At his current weight, that equates to 13-19 lb (6-9 kg) of hay. Offset any nutrient deficiencies in the hay. For example, feed a balancer pellet. Do so at the rate recommended by the manufacturer.

If Griffith is unable to maintain weight on this diet, additional hay can be fed or a concentrate intended for performance horses can be introduced. A concentrate must be fed at the minimum recommended amount to fulfill protein, vitamin, and mineral requirements. If the minimum amount provides too many calories, a mix of the concentrate and balancer pellet can be fed. Fine-tuning any diet often requires a fair measure of give and take to find just the right balance for the individual.

Omega-3 Fatty Acids Benefit Foaling Mares Before Rebreeding

Thursday, December 30th, 2021

Omega-3 Fatty Acids Benefit Foaling Mares Before Rebreeding: When compared to cows, ewes, and sows, mares experience a short interval between birth and their next heat cycle. After foaling, the uterus undergoes involution. Involution is a process that reduces uterine size, repairs uterine tissues, and restores the uterine environment to a nonpregnant state. Supporting uterine involution is critical. The 11-month gestation of the mare often makes it difficult to maintain every-year foaling. Commercial breeders prefer every-year foaling. In a recent study, researchers set out to determine the effects of feeding docosahexaenoic acid (DHA), an omega-3 fatty acid, on uterine involution in the weeks after foaling.

The Study:

The study used eighteen pregnant mares. The mares were assigned to one of two groups. Firstly, a treatment group in which a microalgae rich in DHA was fed daily at 0.6 g/kg body weight. In addition, a control group. The treatment was fed from 90 days prior to the expected foaling date until seven days after first postpartum ovulation. Otherwise, the mares were fed similarly to maintain moderate to moderately fleshy body condition, including access to Bermudagrass pasture and a commercial concentrate at a rate of 1 kg/day (2.2 lb/day) before foaling and 2 kg/day (4.4 lb/day) after foaling.

Research ascertained reproductive health parameters. For example, through rectal palpation and ultrasonographic examination, including uterine and endometrium diameters, intrauterine fluid, uterine tone, and uterine echogenicity. Echogenicity measures the ability of a tissue to reflect an ultrasound wave.

Mares fed the DHA-rich supplement had smaller uterine horn diameters after foaling compared to control mares. Interestingly, DHA-fed mares had greater uterine echogenicity scores. Low echogenicity is generally related to increased estradiol. Estradiol induces edema and estrus behavior, so researchers expected lower scores as mares readied for rebreeding.

No treatment effects were observed for the other parameters evaluated.

Conclusion:

Researchers concluded that “supplementation with DHA during peripartum may benefit uterine involution process and odds of early conception.”

“This research adds to the emerging volume of work that indicates omega-3 fatty acids, particularly DHA, is a useful nutritional supplement for broodmares,” explained Catherine Whitehouse, M.S., a nutritionist with Kentucky Equine Research. Studies in other species show omega-3s have beneficial effects on reproduction. For example, by modifying prostaglandin synthesis and metabolism, and by regulating genes integral to uterine function.

“The source of omega-3 fatty acids is important. Choose a high-quality supplement that delivers DHA directly, such as marine-derived EO-3,” Whitehouse advised.
