Abstract
THE folic acid antagonist pyrimethamine has been shown to act as a synergist with sulphadimidine against Eimeria tenella in chickens1. During our investigation of this combination, a decreased growth-rate was noted in chickens fed for five days on an all-mash diet containing 100 p.p.m. of pyrimethamine.
