Basics of feeding a horse

• Learn the 10 important things to know in feeding your horse.

Horses show a preference for oat color

• There's a belief in the oat market that horses and their owners prefer white-hulled oats.
• Horse owners didn't show a preference for either color oats.
• Horses preferred yellow-hulled oats.
• Owner and horse preference for white-hulled oats weren't validated. 

Providing carbohydrates and fats in your horse’s diet

• The type and amount of carbohydrates horses receive can affect their health.
• Fat is dense in calories and provides a good source of energy for the horse. 

Encouraging your horse to drink

• Always make sure your horse has free access to fresh, clean water. 
• Horses that refuse to drink are at risk of poor performance, poor organ function and colic. 

Hay in horse diets

• Good quality hay provides ample nutrients to meet the needs of most horses. 
• Regardless of the class of horse, forages should make up at least 50% of the daily ration.
• Optimizing forages in your horse's diet will result in a healthier horse and can help reduce costs.

How to take a hay sample

Understanding your hay analysis

• A hay analysis helps you better understand what you’re feeding your horse. 
• Always request a horse analysis when sending in hay samples. 

Harvest moisture level and bale wrapping affects hay quality for horses

• Moisture and bale wrapping affects mold and forage quality.
• Orchardgrass bales are prone to significant mold and poor forage quality at moistures slightly over 15 percent.

Feeding clover to your horse

• Clover is a good feed source for horses.
• There are clover-causing health problems that horse owners should be aware of.
• Learn how to identify different clovers.

Don’t feed your horse moldy hay

• Moldy hay presents risks to horse health.
• Mold spores can produce respiratory disease in horses.

Steaming horse hay to reduce the effects of mold and dust

• Steaming shouldn’t replace the main goal of feeding hay with low mold and dust content.
• In the absence of such hay, steaming is a good practice for reducing mold and dust content in moderately moldy hay.

Determining the value of rained-on hay

• Rainfall on cut hay laying in the field causes yield and quality losses.
• Rained-on hay can be a suitable forage, especially for horses prone to laminitis.
• The best way to check the quality of rained on hay is to have it tested.

Evaluating amino acid levels in forages and horses

• Forage plays a key role in the horse’s diet.
• Cool-season grass and alfalfa are higher in amino acids than teff. Amino acids are the building blocks of protein.
• While alfalfa and cool-season grasses were higher in protein and lower in fiber, horses grazing teff had a similar blood amino acid response.

Evaluating glucose and insulin levels in grazing horses

• Teff has lower nonstructural carbohydrates (NSC) and higher fiber values compared to cool-season grass and alfalfa.
• Blood insulin levels were lower for horses grazing teff compared to cool-season grasses in the fall and late fall.
• The lower NSC and higher fiber values of teff could help decrease the insulin response of horses grazing in the fall and late fall.

Blister beetles in alfalfa hay

• Blister beetle-infested hay can cause health problems and death in horses and other livestock.
• When buying hay from outside of Minnesota, find out where and when hay was harvested.
• If you see black, elongated beetles in hay bales, do not feed to animals and throw it away carefully.

Selecting and storing horse hay

• Horse-quality hay should be baled between 10 and 15 percent moisture.
• Store and protect hay from moisture to best prevent spoilage.

Ten ways to stretch your horse's hay supply
Strategies to optimize and stretch your hay supplies.

Certified hay requirements

The certified noxious weed seed-free forage program assures that certified forage meets the minimum standards to limit the spread of noxious weeds.

• In Minnesota, it is voluntary to use certified hay when trail riding and camping in Minnesota public parks.
• If you plan a trail ride or camping trip with your horse on public lands in the western U.S., you must use certified hay.
• Contact the Minnesota Crop Improvement Association for a list of producers of certified noxious weed seed-free forage in Minnesota: 800-510-6242.

Feeding hay with a round bale feeder

• Round-bale feeders can reduce hay waste.
• Feeder design doesn’t affect the amount horses eat.
• All feeders reduce hay waste compared to not using a feeder, but hay waste differs based on the feeder design.

Using slow-feed hay nets

• Horses would naturally graze for about 14.5 hours a day.
• But many horses spend a lot of time in stalls or dry lots with limited time to forage.
• Horse owners try to mimic a more natural feeding pattern by providing free access to hay, but this can cause horses to eat too much and become overweight.
• Hay nets can help slow a horse’s eating in these situations.

Horse weight loss: hay nets and limit-fed diets

• Slow-feed hay nets and limit-feed diets can reduce weight in overweight adult horses.
• Using these feeding methods together can moderate blood and hormone patterns in overweight adult horses.

Selecting a small square-bale feeder

• We tested small square-bale feeders to evaluate hay waste, cost, hay intakes and herd bodyweight.

Using grazing muzzles to reduce forage intakes in horses

• Grazing muzzles are muzzles that restrict a horse's intake.
• They are effective in reducing a horse's pasture intake by about 30 percent.
• They help in body weight loss for overweight or obese horses.

Feeding your horse a ration balancer

• Ration balancer is a commercial horse feed designed to provide the trace minerals and vitamins your horse needs.
• Ration balancers do not add energy to the diet.

Caring for the overweight horse | Cuidado del caballo con sobrepeso

• Overweight horses are prone to disease, overheating and poor performance.
• Learn how to determine if your horse is overweight.
• Restricting diets and easing into regular exercise can help horse’s reach a healthy body weight.

Caring for the underweight horse | Cuidado del caballo con peso bajo

• Determine why the horse is thin by working with an equine veterinarian and nutritionist.
• Learn how to determine if your horse is underweight.

Soaking your horse’s hay

• Soaking hay can benefit horses with certain health issues by reducing water soluble carbohydrates, potassium and dust.
• Health issues soaking can help with include laminitis, polysaccharide storage myopathy (PSSM), hyperkalemic periodic paralysis (HYPP), chronic obstructive pulmonary disease (COPD).
• Rely on forage tests before and after soaking to decide which type of hay is best for your horse.

Grazing horses prone to laminitis and metabolic disease

• Laminitis, also known and founder, is inflammation of tissues inside the hoof.
• High amounts of sugars or fructans in grasses can bring about disease in susceptible horses.
• Many factors affect the amount of sugar in forages.
• Susceptible horses should have limited grazing or no grazing.

Managing forage carbohydrate content

• Horses require carbohydrates in their diet.
• Some horses are sensitive to the carbohydrate content of hay and pasture forages. This could lead to health problems.

Alternative feedstuffs for horses

• You may consider alternative feedstuffs due to high hay costs or poor hay availability.
• When selecting an alternative feed, evaluate the pros and cons, and always work with your veterinarian or nutritionist.
