Now that we’re well into spring, most barns are scheduling their semi-yearly vaccination and deworming day. Having an established deworming routine with your veterinarian is an essential part of horse ownership and barn management.

Don’t: Leave Parasites Unchecked

When left unchecked, internal parasites can wreak havoc on your horse’s overall health. If you notice your horse is inexplicably losing weight, rubbing his tail out, or developing a duller coat than normal, it may be a good idea to look into when his last deworming treatment was. Minor cases can be straightforward to treat. But larger infestations can cause serious damage and may lead to severe health complications including diarrhea, loss of appetite, lethargy, and colic.

Do: Keep Things Clean

There are several steps horse owners and barn managers can take to combat internal parasites at their farms. Maintaining a clean environment by removing manure piles, especially in shared paddocks, helps minimize the risk of spread between horses. In horses with suspected minor infestations, fecal egg counts can indicate whether a horse has elevated parasitic activity that needs treatment.

Stay On Schedule

Developing an effective yearly deworming schedule helps eliminate any parasites that may be growing. Every barn has a different deworming schedule, and strategies can vary based on geographic location, the average age of horses on the property, and types of turnout arrangements. For this reason, it is crucial to consult a veterinarian before beginning a deworming regimen.
