عنوان انگلیسی Effects of Lactobacillus-Based Probiotic on Performance, Gut Microflora, Hematology and Intestinal Morphology in Young Broiler Chickens Challenged with Salmonella Typhimurium
چکیده انگلیسی مقاله This experiment was conducted to compare the effects of multi-strain probiotic inclusion levels on performance, intestinal morphology, gut microflora and hematological changes in Salmonella typhimurium (ST) infected broiler chickens. A total of 120 day old Ross 308 broiler chickens were distributed into 20 floor pens and reared for 10 days under 5 experimental treatments including a corn-soy basal diet with no probiotic (Control), or 0.5 g (0.05%), 1 g (0.1%), 1.5 g (0.15%) and 2 g (0.2%) probiotic/kg diet. Chickens were infected orally with ST at second day of experiment. Broilers under 0.15% of probiotic had higher body weight gain compared to other treatments. Probiotic supplementation, except at 0.05%, significantly improved feed conversion ratio. The use of 0.1 and 0.15% of probiotic reduced the population of Salmonella in ileum. The lowest heterophil:lymphocyte ratio was observed in 0.15% of probiotic, although 0.1 and 0.2% of probiotic significantly reduced this ratio compared to control group. Adding 0.15% of probiotic to the basal diet increased (P
