abstract
Eighteen calves were divided into 3 groups of 6 animals each in a completely randomized design. Group I served as control whereas the animals in groups II and III were experimentally infected with 2and 3 tick equivalent of Theileria annulata sporozoite. Intake, digestibility of nutrients and N-balances did not differ among the groups during the incubation period. During clinical phase feed intake and N balances were reduced in infected groups. Lower Hb content from day 7 of infection noticed in infected groups. Theileriosis reduced feed intake, N-balance and Hb during clinical phase. Digestibility of the nutrients was not affected.
