ABSTRACT

In order to reduce the use of antibiotics in broiler farming, the use of probiotic microorganisms and beneficial food substances has been opted for. So on the first day, 1013 chicks were raised in groups until the 7th day. Then, 999 chicks were randomly divided into 3 comparable groups with three repeats each, on day 8. A control group (Group T) was subjected to an antibiotic prophylaxis program, an experimental group (Group 1) where chicks received only the Polybiote (a probiotic) and the last experimental group (Group 2) where chicks received the Polybiote associated with Renfort⁺ (a prebiotic). Blood samples were weekly collected from 15 chickens from each batch and kept in suitable tubes. Chickens haematological and biochemical parameters were measured. The results of this research work showed that the leukocyte and erythrocyte parameters of chickens fed with the polybiote associated with Renfort⁺ (Group 2) were significantly increased (p ˂ 0.05) compared to those of the control group (Group T). As for the biochemical parameters, the total serum protein concentrations of chickens in groups 1 and 2 were significantly increased (p ˂ 0.05). However, the activities of the enzymes of chickens in group 2 were significantly lowered (p ˂ 0.001) while its serum calcium concentrations were increased compared to group T. It emerged from our experiment that chickens subjected to the Polybiote alone or associated with the Renfort⁺ did not show any abnormalities and had better biological characteristics. It could, therefore, be used as natural substitutes for synthetic antibiotics.
