Feeding 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.
Domestication significantly altered equine diets. This 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. Their workload dramatically decreased compared to past times. Even so, some horses are still fed too many energy-dense feedstuffs (concentrates) and insufficient preserved forage or fresh pasture. The availability of quality forage 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.
- Introduce small amounts of chaff into the diet. Introduce especially 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.

Lighting & Nutrition for Breeding Late Winter/Early Spring: Mares that are not pregnant at the end of the year should be getting careful attention in December and January to make certain that they are ready for the start of the breeding season.
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.
Forage makes up between 50 and 90 percent or more of a horse’s diet. Much of the forage part of the diet comes in the form of hay. Because it’s such a big part of the ration, a good quality hay can help keep a horse healthy, while a poor quality hay can be detrimental. This is why, as nutritionists and horse owners, we put a big emphasis on the quality of hay we feed.
Fat is important for performance horses. The use of fat in the equine diet has a long history. A very old book, Horse Secrets by A.S. Alexander, published in 1913, points out that horse traders knew back then that adding fat to the diet was beneficial for gaining weight and improving hair coat. They may not have known why it worked, but they knew that it worked!
