Effect of Cocciban herbal coccidiostats on hematobiochemical, fecal parameters and cecal histopathology of broiler chicken.

The objective of the present study was to investigate the comparative efficacy of recommended dose of selected anticoccidial drugs Salinomycin and Dinitolmide, while Cocciban at three dose levels on the hematobiochemical, fecal parameters and histopathology of broilers. For this purpose, 420-day-old commercial male broiler chicks were randomly divided into 7 treatment groups with 10 replications of 6 birds each and reared in battery brooders up to 42 days of age. Groups were designated as uninfected unmedicated (T1 ), infected unmedicated (T2 ), Cocciban 500 g/ton and infected (T3 ), Cocciban 750 g/ton and infected (T4 ), Cocciban 1000 g/ton and infected (T5 ), Salinomycin 500 g/ton and infected (T6 ), and Dinitolmide and infected (T7 ). Groups T2 , T3 , T4 , T5 , T6 , and T7 were experimentally infected at 21-day-old by 50,000 oocysts of Eimeria species. The mean fecal, lesion scores and oocyst per gram of feces were significantly (p < 0.05) highest in infected unmedicated group, while lowest in the herbal Cocciban 1000 g/ton group than all other infected medicated groups. The hematological studies revealed a reduction in TEC, Hb, and PCV from 0 to 5th day of P.I. in all infected groups except healthy control group. The birds of all the infected groups improved in the values of TEC, Hb, PCV, blood glucose, and total serum protein on 7th day of P.I., but, the improvement was significantly (p < 0.05) better in herbal Cocciban 1000 g/ton treated birds than all other infected groups. Whereas, the TWBC counts were raised from 0 to 7th day of P.I. in all the infected groups compared to healthy control and no significant (p < 0.05) difference was observed in between the infected groups. The histopathological changes consisting of desquamation of epithelial cells, cellular infiltration, hemorrhages, edema, fibrous tissue proliferation, and developing stages of E. tenella at various depths of cecal wall were higher in all the infected groups when compared to Cocciban 1000 g/ton group.
