The anthelmintic activity of a single oral dose of thiophanate at the rate of 50 mg/kg of body weight was determined by the Field trial method against nematodes in cattle and buffalo calves. In cattle calves, thiophanate at the rate of 50 mg/kg was highly effective (100 percent) in reducing Mecistocirrus digitatus eggs throughout the eight experimental weeks. The drug was also highly effective (90.4 to 100 percent) in reducing strongyloides papillosus, Bunostomum phlebotomum, Charbertia, Cooperia, Haemonchus, Oesophagostomum and Trichostrongylus eggs from the first to seventh week after treatment. In buffalo calves, thiophanate at the rate of 50 mg/kg. was highly effective (100 percent) in reducing Neoascaris vitulorum eggs throughout the eight experimental weeks. The drug was also highly effective (90.8 to 96.3 percent) in reducing S.papillosus eggs from the first to eighth week after treatment.
