title: Effect of Lactobacillus fermentum and Enterococcus faecium strains on internal milieu, antioxidant status and body weight of broiler chickens.
abstract: The aim of the present study was to evaluate the functional efficiency of two probiotic strains Lactobacillus fermentum CCM 7158 and Enterococcus faecium M 74 given to the drinking water on internal milieu, antioxidant status and body weight of broiler chickens. The experiment was conducted on hybrid Hybro (n = 180). The feeding period lasted 42 days. Experimental chickens of E1 group received a probiotic preparation in drinking water with concentration of 1 × 10(9) colony forming units (CFU) of L. fermentum CCM 7158 in 1 g of nutrient medium and experimental chickens of E2 group concentration of 2 × 10(9) CFU of E. faecium M 74 in 1 g of nutrient medium. The control group of animals received water without any additives. Triglycerides content in serum mainly with L. fermentum strain against the control group was decreased. Calcium content in both experimental groups and significantly in E. faecium group was increased. Antioxidant status in both probiotic groups was significantly increased. The content of bilirubin in group with E. faecium M 74 was significantly increased. In conclusion, addition of a microbial feed additive (L. fermentum and E. faecium) increased serum calcium and iron level, decreased triglycerides content in blood and slightly increased body weight of broiler chickens.
