Anthelmintic activity of single doses of thiophanate at the rates of 70,100,200,300,400 and 500 milligrams per kilogram of body weight and continuous dose of thiophanate for 14 consecutive days at the rate of 10 milligrams per kilogram of body weight were determined by the critical test against endoparasites in 80 chickens. Thiophanate at a dose rate of 70 and 100 milligrams per kilogram was no effective in removing Ascaridia galli and Raillietina spp. Thiophanate at the dose rates of 200, 300, 400 and 500 milligrams per kilogram were 5.3, 75.1, 87.5 and 96.4 percent, respectively in removing A. galli. Whereas, neither dose of the drug was effective in removing Raillietina spp. Thiophanate at a dose rate of 10 milligrams per kilogram for 14 consecutive days was 51.6 percent effective in removing A. galli, but the drug was no effective in removing Raillietina spp. Thiophanate was well tolerated by chickens when administered as single dose up to 5,000 milligrams per kilogram of body weight.
