Kentucky Equine Research responds: Feeding corn to the horse is not an issue, as it is often an ingredient in high-quality, well-formulated feeds. The concern involves where the corn was stored and for what duration it was there.

Corncribs are relics on most farms these days. Usually fashioned from wood, they were once commonplace on farms. The walls of the corncribs were typically not entire, purposely left open to allow air to circulate throughout. While ventilating the corncribs was essential for keeping the corn dry, the openness often allowed rodents and other vermin to gain access.

If ear corn becomes wet during storage in a corncrib, there is a chance that mold will develop. Unlike cattle, horses are extremely sensitive to mold. This is evident in the difference in hay that can be fed to the two species; generally cattle can tolerate more dust and mold than horses can.

If a horse consumes corn contaminated with toxins produced by Fusarium spp., it might be at risk for moldy corn poisoning, also known as equine leukoencephalomalacia. This disease progresses quickly in most animals with death occurring within a few days. Clinical signs of the disease include anorexia, lethargy, and a roster of neurological deficits: staggering, circling, head-pressing, and inability to swallow.

Though this is not a common disease, it is a deadly one and there have been numerous outbreaks recorded throughout the United States. Cases seem to pop up in late fall through early spring and are especially prevalent when a dry growing season is followed by a rainy fall.

While contaminated kernels might be off-colored, there is no definitive way to tell if corn is infected with the disease-causing fungus by visual inspection. Corn screenings, a by-product of corn handling and processing that contain, among other things, whole and partial kernels of corn, are another likely source of contamination.

The best way to prevent a case of moldy corn poisoning is to provide horses with a professionally formulated and manufactured concentrate that is appropriate for age and lifestyle. When fed by itself as a concentrate, corn does not supply adequate nutrients for optimal health.

The temptation to give horses treats is a great one, but I'd stick with more traditional ones: apples, carrots, or an occasional alfalfa cube.

Kentucky Equine Research responds:  Both sweet potatoes and carrots can be offered to your horses as treats. Carrots contain about 88 percent water, while sweet potatoes have about 77 percent, making sweet potatoes slightly more nutrient-dense. Both are relatively poor sources of protein because of the high water content (carrot, 0.9 percent; sweet potato, 1.6 percent; as fed).

The primary nutrient difference lies in the carbohydrate content of the two root vegetables. Although the fiber content (carrot, 2.8 percent; sweet potato, 3 percent; as fed) and the simple sugar content (carrot, 4.7 percent; sweet potato, 4.2 percent; as fed) are similar, sweet potatoes are much higher than carrots in starch (12.9 percent and 2.1 percent; as fed, respectively). Looking more closely at the type of starch in the sweet potatoes, 80 percent is rapidly digestible (enzymatic digestion), while only 11 percent is resistant starch only fermentable by microbes). Sweet potatoes provide over twice the calories that carrots do (86 and 41 calories, respectively, per 100 g), mostly because of the difference in starch content. In this context, “as fed” refers to raw vegetables and “dry matter” to dehydrated vegetables.

While dehydrated sweet potatoes have less sugar than dehydrated carrots (18 percent and 40 percent, respectively), they have similar levels when fed raw (4.2 percent and 4.7 percent, respectively), as noted previously.

Both are rich sources of beta-carotene, which is the precursor to vitamin A.

Despite their names, sweet potatoes and Irish potatoes are not closely related from a botanical standpoint. Sweet potatoes and yams are vines in the morning glory family, whereas Irish potatoes are in the nightshade family. Sweet potatoes do not contain the nutritional anti-factors that make raw Irish potatoes unsafe for horses to consume.

Sweet potatoes can be a tasty treat for horses either raw or cooked. Due to their relatively high starch and sugar content, they should be fed in only small amounts. Feeding large amounts carries some risk, especially when given to starch-sensitive horses. In addition to beta-carotene, sweet potatoes are a good source of vitamin C and potassium.

Some horse owners feed up to 10 gallons (or more) of carrots to their horses with no ill effects, reporting that the carrots add weight and are a good water substitute. Kentucky Equine Research notes if the horse doesn't have metabolic issues, there is most likely no harm in feeding that quantity of carrots, but there is concern as to if the horse is obtaining all the dry matter and nutrients needed for a healthy diet. 

Carrots are primarily water (85 to 90 percent), so they do assist in keeping a horse hydrated. Assuming one five-gallon bucket of carrots is a meal, the horse would be consuming just 1.5 pounds of dry matter, of which 25 percent is water-soluble carbohydrates. As the horse takes a while to eat through the bucket of carrots, the nearly six ounces of sugar and three ounces of soluble fiber from the carrots slowly enters his bloodstream. 

The high amount of water could make the horse's manure loose and provides him with a lot of calories, so he may pack on the pounds. Additionally, the horse's coat may develop an orange tint as some of the beta-carotenes are absorbed as carotenes by body tissues. Carrots do not contain significant amounts of other nutrients.

Hallway director of sales and marketing Anthony Koch said the boxes are a fun way for horse owners to show their horses they care, and a good introduction to Hallway's brand. It's also a timely reminder of the economic impact of the upcoming breeding season on the state, where 228 stallions will meet 17,241 mares this year.

Lacroix recommended vets talk with their insurance provider and the licensing board in their state before ever chatting with clients about CBD. She reported some shocking statistics: in six states, a veterinarian can lose their license if they even discuss CBD with a client; in two state the conversation must be initiated by the client or the vet can lose his or her license. In 18 states, the vet can discuss CBD products, but cannot prescribe or dispense them.

Why is there such an uproar about hemp, which is legal for human use in multiple states? Lacroix says there are a few reasons:

• The U.S. Food and Drug Administration doesn't approve the use of hemp in any form for animals
• CBD is still illegal at the federal level
• A “nutritional supplement” must contain one or more ingredients that occur naturally in a horse's body; CBD is not naturally found in animals, so it cannot be a nutritional supplement
• Nutritional supplements cannot claim to treat, mitigate or prevent a disease or a condition; if that claim was made, the supplement would be a drug that would require USDA approval
• Limited research has been done on CBD use in horses; much of the data comes from small animal research

It is not illegal for a horse owner to give CBD to his or her horse, since they are not a licensed veterinarian. It is also not illegal for companies to make products that contain CBD as long as they do not claim the product helps with a condition or disease.
