Technical Abstract: Gastrointestinal nematodes cost American beef producers approximately $10- 20 per head of cattle. These losses are a result of decreased growth in the animals because of altered nutrion and impairment of the immune system. The animals suffer damage to their gut resulting in decreased protein digestion, and also suffer from loss of appetite. Effects on the immune system result from decreased protein digestion, disruption of the immune system, and the release of immunosupressors by the worms. There are no accurate ways to determine the number of parasites in a given animal, and at this time the best way to control the parasites is by decreasing transmission levels on pastures. The development of successful control programs requires the involvement of Veterinarians or Parasitologists who are familiar with parasite transmission problems in the area surrounding the farming or ranching enterprise.
