Alternative therapies such as message therapy, acupuncture, and chiropractic care all seem to help make sore horses feel better and are not discouraged. The best practice for prevention is to have a healthy, fit horse, so that if the disease is acquired, it can more easily be fought off. All routine preventative health care management is required for EPM also. The healthier the immune system, the more sporocysts the horse must ingest before coming infected. It is very important to keep the accessibility of your barn to opossums to an absolute minimum.
Opossum are prolific and in a short time the opossum population can be overwhelming.
They will also eat almost anything edible. Cleanliness is a must. Wire fencing is available to prevent opossums from entering pastures. Live trapping and relocation of opossum are options to reduce the amount of feces in the area. Buying pelleted feed may be a safeguard against EPM as extrusion processes may be hot enough to kill to protozoans.
