FECAL EXAMINATIONS

One of the most under-utilized tools in an effective parasite control program is the fecal examination, which merely involves taking two to three fresh fecal balls to your veterinarian for laboratory analysis. This simple process can identify the specific parasites infecting a horse. Rarely are the worms themselves visible in the manure. By counting the types and numbers of parasite eggs present in the fecal sample, your veterinarian can recommend the right deworming agents to do the job. Fecal eggs per gram counts (EPG) also tell an owner about the degree of parasite infestation on a farm or within a herd.

The fecal exam is a cost-effective follow-up to deworming to determine whether the dewormer has worked. It's good practice to do a fecal EPG count within two weeks after deworming.
