“It’s not about zero parasites, its about keeping the horse healthy.” Interview with Dr. Ed Jedrzejewski

In domesticating the horse, we created a few problems for him. One of these problems is parasites. Or in plain language – worms. Its actually natural for a horse to have some parasites living inside him. But the problems begin when the horse has too many worms – a high parasite load.

Then the horse’s health can be affected, sometimes in a mild way by the horse losing appetite, having difficulty gaining weight, or losing his shiny hair coat. Other times the effects of parasites may be more severe, resulting in damage to the digestive system, colics, or intense itching and rubbing.

As horse owners and caretakers, we receive a lot of conficting advice on how to best handle these worms. We are told to use a certain brand, rotate chemicals, deworm every 8 weeks, do fecal testing, etc, etc.

In order to get the facts on the worm issue, I made a trip back to Penn State University to interview Dr. Ed Jedreweski, DVM, Horse Barn Manager.
