The role of high-grade Bentonite powder in coccidiosis and its effects on feed conversion ratio and blood parameters in broiler chicken

The aim of this study was to evaluate the effect high doses calcium bentonite on blood parameters, anticoccidial activity and intestinal histology broiler chickens. Three undred sixty one-day old broilers were distributed into three treatments (T+VE, T-VE, TB )with replicates. Amprolium added feed positive control group, powder nothing T-VE group. Coccidiosis induced day 14, birds kept until 49, measurements different variables started from week 3, samples collected via wing vein, fecal oocysts counted contents each individual bird using McMaster techni- que. A decrease in consumption, body weight gain conversion ratio noticed Broilers group (TB ) negative (T-VE showed clinical signs coccidiosis (blood feces) number feces increased with time. Histopathological examinations affected caeca also demonstrated excessive tissue damage, hemorrhage, presence clusters large schizonts merozoites tissue, coccidian lumen. Feed highest T+VE
