Storage A Concern When Feeding Corn On The Cob

Question: A fellow boarder was feeding her horse ears of field corn one evening. The kernels were hard and a deep golden color. I asked her if this was from this year's planting, and she said it was from an old corncrib that was on a relative's farm. Is this a safe practice?

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.

Study: Thailand’s African Horse Sickness Outbreak Likely Started From Just One Animal

Scientists have found that the 2020 outbreak of African Horse Sickness in Thailand most likely came from just one affected animal entering the country. Hundreds of horses were killed in the country's first outbreak of the disease, which is spread by biting midges.

Dr. Napawan Bunpapong and a research team from Chulalongkorn University in Bangkok used molecular-based testing to help determine the disease's origin. They discovered that every blood and tissue sample taken from affected horses in Thailand contained the virus, and more specifically, contained unique amino acids, indicating a single, common origin. The researchers suggest that the virus may have come from an asymptomatic animal like a zebra.

The government of Thailand restricted movement and enforced quarantine, disinfection and vector control to try to staunch the spread of the disease. Mass vaccination was also completed in Thailand and neighboring countries.

Affected horses had a fever and swelling near their eyes; they became depressed and short of breath before dying suddenly within 48 hours.

Kentucky Position On EHV Quarantine At Saratoga Race Course

E.S. “Rusty” Ford, equine operations consultant for the Kentucky Office of the State Veterinarian, released the following update regarding a diagnosis of EHV-1 at Saratoga Race Course.

On Thursday evening (7/15) we received notification that Barn 86 at Saratoga Race Course had been placed under quarantine by NYRA Veterinary Officials and New York's Gaming Commission following a diagnosis of EHV1 in a horse that had been stabled on the grounds. Since that time, we have maintained open lines of communication with both NYRA and the NY Department Agriculture's State Veterinarians Office and have been working with the KY Horse Racing Commission and KY racetrack's management teams.

A description of the disease event can be viewed on the Equine Disease Communication Center's website.

Additionally, we did reaffirm earlier this morning that the status is unchanged and there have been no new EHV cases reported.

Dr. Flynn and I would like to take this opportunity to remind you that mitigating risk of disease introduction and transmission is a shared responsibility with success dependent on multiple parties all working together to achieve the common goal of maintaining safe and healthy environments for our horses. Since Thursday, we have worked closely with our tracks and training facilities to establish procedures and protocols that continues to allow movement of horses originating from Saratoga Race Course onto Kentucky tracks. With that in mind, we want to ensure that other equine facilities receiving horses understand the importance of having strong biosecurity protocols in place and practiced daily when processing and managing new arrivals onto your facility. Your veterinarian is a valuable resource to review and give recommendations based on your individual premises and we, too, will be happy to review your plan and share our thoughts on best practices.

Kentucky's Position at This Point in Time: With horses in the affected barn remaining under quarantine, segregated from the general population, and being closely monitored for evidence of illness, we are satisfied horses residing in other barns at Saratoga can qualify and be permitted entry onto our Kentucky tracks and training facilities by fully meeting our established entry requirements. These requirements include a Certificate of Veterinary Inspection (CVI) certifying examination and issuance of the certificate was made during the 72-hour period preceding the horses arrival at the Kentucky track/facility and includes certification of the horse meeting our established EHV1 vaccination requirement as well as EIA testing.

Additionally, I am encouraging tracks to have the shipping of horses from Saratoga onto the grounds be scheduled with the stable manager and that the arrival and stabling information be shared with the track's Equine Medical Director or his designee.

We appreciate the opportunity to provide factual information resulting from the open lines of communication with NYRA and NY Department of Agriculture veterinary officials. We will continue to monitor this developing event and provide updates as new information is learned or a change in the status occurs.

Runny Nose: Nuisance Or Something More Serious?

With the rise in cases of both equine herpes virus and strangles in horses in the United States, horse owners and caretakers have every right to be on high alert to any changes in a horse's health or demeanor. Though some symptoms are always a red flag — like a horse who's unsteady on his feet — some symptoms can be caused by something far less sinister than an equine illness.

A horse with a runny nose is always something to note, but a bit more work may be required to determine its cause.

Look closely at discharge color, odor, quantity and consistency, as well as if there is anything in the discharge like dirt, debris or feed. Notice if the discharge is coming from one nostril or two, as well as the horse's demeanor. A check of his vital signs is in order.

If the horse's nasal discharge is clear and thin, and he's bright and acting normally, he most likely inhaled some dust or hay and has irritated his nasal passages, but is otherwise fine. A small trickle of bright red blood that stops bleeding in minutes is also most likely nothing to be concerned about—the horse probably got poked with a piece of stemmy hay.

The following require a call to the vet as they may indicate serious issues:

Discharge that includes saliva or chewed food, which could mean the horse is choking.
Bright red blood that is flowing freely for more than 30 minutes may be a sign of nasal passage injury.
Blood that is dark and draining could indicate that the horse has blood accumulating in his sinuses or respiratory tract.
Thick, yellow mucus can be a sign of a viral or bacterial infection, or strangles.
Discharge that smells, which may be indicative of an infection.

If the discharge indicates the horse may have an infection or contagious disease, keep him away from other horses and tell the vet what he or she may be dealing with before they arrive so they can adequately prepare. Don't handle any other horses before the vet arrives; if there's no other option, be sure to wash and sanitize hands and change clothes whenever possible.
