Parasite Control

Parasite resistance has been a hot topic among the equine world in recent years. This has developed due to horses receiving dewormers too frequently and at too low of a dose. This has resulted in many products that are partially ineffective against worm burdens.

At Twin Pines Equine, we are recommending a strategic deworming program. Every horse is different and their parasite load needs to be treated individually. Parasite load is determined through the use of Fecal Egg Counts. Through these fecal exams, we can classify your horse as a "high shedder" or a "low shedder". We can then create strategic deworming schedules, which minimize the frequency of treatment while increasing efficacy.

Recommended Deworming Schedules

In each case, a fecal sample is to be submitted BEFORE the deworming product is given. To collect a fecal sample, collect about 2 fecal balls of fresh manure, place in a plastic bag and seal with air expressed. Store this sample in the refrigerator until it can be picked up or delivered for testing, within 36 hours of production. We charge $10 per test, and can have the results to you within 3-5 days.

Adult Low Shedder

Adult High Shedder

*A Fecal Egg Reduction Count (FERC) should be performed 10-14 days after administration of Pyrantel or Oxibendazole, once every 2 years. This is a repeat Fecal Egg Count which, when compared to the one done before the dewormer was given, allows us to assess resistance to this product.

Foals

Do NOT deworm foals under 6 months with Moxidectin.

Oxibendazole is very similar to Fenbendazole, but may be more effective. If Oxibendazole cannot be found, Fenbendazole may be used in its place.

PLEASE NOTE: THIS IS ONLY A GUIDE! Numerous factors control the level of parasites in your horse. It is ESSENTIAL to consult your veterinarian to develop an individualized deworming program for your unique situation.
