Twelve Bonsmara tracer calves (aged 6-12 months) were used to monitor helminth infections in the communal farming system of Botshabelo in the Free State. One calve was slaughtered each month from December 1995 to November 1996 and processed for helminth recovery. All the calves harboured worms, but the numbers were always low. The order of prevalence of the major parasites was Trichostrongylus axei, Haemonchus placei, Cooperia punctata and Cooperia pectinata.
