Internal Parasite Screening

Internal parasites of horses can cause a variety of clinical signs including weight loss, poor performance, diarrhea and colic depending upon the degree of infestation.  At the New Jersey Equine Clinic we perform accurate screening tests on equine fecal samples to determine if parasites are present in a quantity that required deworming.  Appropriate deworming protocols are then prescribed for your horse.

There is major concern that excessive deworming of horses without regard to their individual parasite burden is leading to drug-resistant parasites.  Sampling of large herds of horses has indicated that only a few horses in the herd carry large numbers of parasites while others are minimally infected.  For this reason, parasitologists now recommend that not all horses should be wormed the same, but should be treated based upon individual need as determined by routine fecal egg counts.
