Recent evidence suggests that basing a deworming program on fecal egg counts enables the horse owner to personalize deworming schedules for each of their horses and reduces the chance of developing anthelmintic-resistant parasites. Hopefully, tailoring a schedule to each horse's needs will also prove to be more time- and cost-efficient in the long-run.

The use of routine fecal egg counts allows veterinarians to decide which horses require deworming and when they should be dewormed. Many veterinarians are now encouraging their clients to perform routine fecal egg counts in horses over one year of age as part of a responsible wellness program.

Follow-up fecal egg count should be performed about 14 days post-treatment to ensure adequate reduction in the number of parasites.
