Endoparasite control.

The gastrointestinal nematodes are considered to be the most important group of internal parasites. Gastrointestinal parasitism is a major constraint to animal health, productivity, and profitability in grazing livestock production systems. The clinical manifestations of infection may range from no apparent effect to death. Despite years of research, assessment of production losses in many regions of the United States and of the potential impact of gastrointestinal nematode control remains to be determined.

Diagnostic methods for parasitic infections in livestock.

Parasitic infections are a primary cause of lost productivity in livestock world-wide. Accurate detection of parasites depends on many factors, including collection, storage, and transport of the sample, as well as the method of laboratory evaluation. However, the presence of a particular parasite does not always indicate the presence of parasitic disease. For many parasites, there exists a level at which the effect on production characteristics is balanced by the effect on the development of immunity. Interpretation of test results, therefore, should also consider such factors as the age of the animal or animals, clinical history, nutrition, local epidemiology of the parasites prevalent in the area, and any treatments that have been implemented.
