Dr. Ley is a nationally recognized leader in his area of expertise but there is more to his education, background, and training than just being a reproductive specialist. He taught veterinary medicine and preventive health care management for well over 20 years at 4 major Universities across the United States before entering private practice. He has provided veterinary services to some of the largest horse, sheep and alpaca farms in the U.S. He administers and delivers farm management programs and individual animal health care from the ground up. His practice motto, “Supporting the life of your equine dreams”, is all encompassing from prior to conception to beyond retirement. And that includes alpacas and llamas too! READ MORE HERE>>>

Parasite Control:

Parasite control must be tailored to the individual farm. Recommendations from other farms or other areas of the country have little usefulness on your farm. We recommend that parasite control strategies be developed with the aid of fecal parasite egg counts. Fecal egg counts done approximately 2 weeks after de-worming medication has been administered may aid in evaluation of development of parasite resistance.

Most prevention against the meningeal worm larval infection is aimed at killing the larvae during their migration, but prior to entry into the spinal cord. This requires a de-worming frequency of at least every 4 to 6 weeks at least during the high risk periods of the year (April-May through November-December in the Eastern Mid-Atlantic states). The most efficacious anthelmintics for protection against meningeal worm have been ivermectin (1 cc of 1% ivermectin per 100 pounds body weight, injected under the skin, every 4 to 6 weeks) or fenbendazole (4.5 cc of 10 % fenbendazole per 100 pounds body weight, given orally, once daily for 3 to 5 days).
