An experiment was conducted to investigate the efficacy of market drug (Rumizyme) and self formulated rumenotoric drug on the rumen protozoa such as Dasytricha, Isotricha, Entodinium and Diplodinium and effects on rumen pH of crossbred calves. The trial was conducted with twenty seven crossbred calves and divided randomly into three similar groups (3 calves in each) for three different trials (1st, 2nd & 3 rd Trials) and each trial was conducted for 60 days excluding pre experimental period. Group T2 and T3 were supplemented with market drug (one bolus/day) and self formulated rumenotoric drug (40 gm/day) respectively for each animal while group T1 (control) was fed without any drug. During each trial at 15, 30, 45 and 60 days of interval the Dasytricha, Isotricha, Entodinium Diplodinium, and rumen pH were measured. Results revealed that the administration phytogenic feed additives significantly (P<0.05) increased the population of Dasytricha, Isotricha, Entodinium and Diplodinium in T3 followed by T2 and minimum in T1 group in each trial at different periods. The rumen pH significantly (P<0.05) decreased in T3 group followed by T2 and T1 at different time intervals (15, 30, 45 and 60 days) during each trial.
