New era of parasite control

BMPs for beef cattle

Abstract

Control of gastrointestinal nematodes (GIN) may have economic and health impacts in beef cattle operations. In the past several decades, GIN control has relied almost exclusively on the use of anthelmintics. With the increase in anthelmintic resistance (AR) new strategies must be developed. Knowledge of GIN biology and epidemiology in the region based on climate and weather, and specific information from the ranch, such as quantitative fecal egg counts, estimates of AR through fecal egg count reduction tests, ages of the cattle and pasture management are necessary to develop GIN control programs. Control programs should integrate grazing management, management of the immune system so cattle can resist infection, and anthelmintic use.
