Does your horse Have EPM?

Identifying EPM early is crucial for effective treatment. Here are some indicators and self-tests you can conduct to assess your horse's condition.

Firstly, observe your horse for any signs of neurological impairment. Common symptoms include incoordination, muscle atrophy, difficulty swallowing, and changes in behavior. Pay attention to whether your horse exhibits a lack of balance, especially when turning or backing up. If you notice any of these issues, it may warrant further investigation.

One simple self-test involves the “tail pull” method. While standing beside your horse, gently pull on the tail and observe how your horse responds. A healthy horse will naturally resist and maintain balance. If your horse sways or stumbles, it could indicate neurological problems, including EPM.

You can also perform a “straight line test.” Walk your horse in a straight line and observe its gait. Look for any signs of lameness, unsteadiness, or a tendency to drift to one side. Inconsistent or wobbly movement may indicate a neurological issue.

Additionally, check for proprioceptive deficits by performing a “foot placement test.” Gently lift one of your horse’s front legs and move it sideways, then release it. A healthy horse will quickly place its foot back in the original position. If your horse hesitates or places the foot incorrectly, it may indicate an issue with its neurological function.

Another aspect to monitor is changes in muscle tone and condition. Inspect the horse for muscle wasting, particularly in the hindquarters. As EPM progresses, you may notice asymmetry in muscle development, which can be a clear sign of neurological issues.

It may seem odd, but there is much discussion about whether or not you should test your horse before treating them for EPM.   In many areas, for example Texas and Oklahoma, many horse professionals take a "treat and see" approach rather than testing, as EPM is so prevalent.   

Treating your horse for EPM before testing can be a more proactive approach, especially if you suspect the condition. Early intervention can prevent the progression of neurological symptoms, which can significantly impact your horse's quality of life. The cost of testing for EPM can range from $200 to $400, depending on the lab and the specific tests performed. In contrast, a option like Karbo Combo from The Karbo Store is priced at $125 for 5 pounds , which would cover a 1000 pound horse for about a month (27 days.) at the recommended feeding schedules.  

By choosing to treat first, you may save on the costs associated with testing and potentially avoid the expenses linked to advanced disease progression. Moreover, timely treatment can lead to a quicker recovery and a return to normal activities for your horse. Prioritizing your horse's health through immediate action, rather than waiting for test results, can be a strategic decision for any horse owner.
