Effect of Enterococcus facium isolates from Coracias garrulus and Lactofeed probiotic on performance, blood parameters and intestine microflora of broiler chickens

The purpose of this study was to investigate the effect of Enterococcus facium isolates from intestine of Coracias Garrulus(SE) and lactofeed probiotic on performance and carcass characteristics parameters of broiler chickens. A total of 280 chicks were arranged into 28 experimental units with 7 treatments in a completely randomized design. The treatments were included control, spraying Lactofeed, drinking Lactofeed and spraying drinking Lactofeed(LF) and spraying SE, drinking SE and spraying drinking SE. Spraying and drinking suspension with 1×1011 cfu were done on 1, 10, 24 and 35 days. The blood of two birds from each replicate was gathered at 28 and 42days. The body weight was increased when birds received SE and LF. The FCR were lower in birds received drinking probiotic and in spraying drinking SE as compared to control. The addition of SE and LF were decreased the serum cholesterol (176 vs, 121 and triglyceride (105 vs. 65)concentration of broilers. The antibody response against SRBC was increased in birds received SE and LF (8.12 vs. 5.83. The jejunum population of gram positive (4.05 vs. 18.38) and gram negative bacteria (13.68 vs. 4.99) were increased and decreased, respectively, in experimental treatments. It is concluded that supplementation of Enterococcus faciumisolates or lactofeed probiotic to water of chicks or spraying may improve the body weight and FCR, immune system and jejunum microflora of broiler chickens.
