We all want the best care possible for our horses. The Heath & Education section covers both Learning Institutions, Organizations as well as many sources for equine assistance including Veterinarians and Farriers.

Everyone can learn from Fine Art and there are some specialty Museums that might surprise you.
Horses as a therapy partner enrich the lives of the disabled. These facilities are listed in our Therapeutic Riding section. To help children and young adults build confidence and grow emotionally, please see the resources available on the Youth Outreach page.
Looking for a place to keep your horse? You can find it in the Horse Boarding section. Traveling? Find a Shipping company or Horse Sitting service if your horse is staying home!

Horsemen’s Laboratory was recently asked how long does deworming medication stay in a horse’s body (residual time)? This question has stimulated a lot of discussion about deworming medications. To answer this question I thought it was best to first discuss the different dewormers according to class of dewormers, based on their chemical make up and mode of action.
Macrocylic Lactones are the only dewormers that are absorbed from the gut into the tissue of the horse when given at the normally recommended dosage. They appear to be the only dewormers that remain in the body for any length of time when given at the normally recommended dosages.
Benzimidazoles may be absorbed when given at higher than the recommended dosage such as when fenbendazole is given for 5 days in a row. The 3 classes of drugs are listed below according to when they first became available for use as deworming medications for horses in the United States.
- Benzimidazoles 1960’s
- Pyrimidines 1970’s
- Macrocylic Lactones 1990’s
No new dewormers have been brought to market for horses since the 1990’s and no new ones appear to be likely in the near future, therefore, every effort must be taken to slow the development of resistance to the drugs we have.

Recently one of Horsemen’s Laboratory clients asked about the accuracy of our testing methods. Horsemen’s Laboratory was established in 1992 and since then we have done over 46,000 samples. Over the years we have sent samples to the University Of Illinois School Of Veterinary Medicine Department Of Parasitology and to East Tennessee Clinical Research, Inc., a very competent laboratory that does extensive testing and research in the field of parasitology, owned by Craig R. Reinemeyer, DVM, PhD, Dipl. ACVM. The results found at all three laboratories were very comparable; placing each horse in the same category as far as egg shedding was concerned.
