Haematological changes in broiler birds with induced caecal coccidiosis following prophylaxis with different coccidiostats

The study was undertaken on Cobb-400 strain of broiler birds (n=300) reared on battery cage system with standard protocols to know the comparative efficacy of 4 commonly used coccidiostats through haematological alterations in experimentally E. tenella infected birds. Fifty day-old chicks each of T1, T2, T3 and T4 group were given coccidiostat Diclazuril (0.1%), Salinomycin (12%), Diclazuril + Salinomycin and Maduramicin (1 %) at a dose rate of 100, 50, 100+50 and 50 g/100 kg feed, respectively. Group T5 was kept as infected control and T6 as uninfected control without coccidiostat. Infection of E. tenella @ 50,000 oocytes was induced at three week of age in group T1 to T5 to see haematological changes after 1 wk of infection. | Haematological changes in broiler birds with induced caecal coccidiosis following prophylaxis with different coccidiostats
