Effect of Probiotic Strain Enterococcus faecium M74 Supplementation on the Carcass Parameters of Different Hybrid Combination Chickens

Abstract

The aim of the present study was to evaluate the effect of addition of Enterococcus faecium M74 in drinking water on performance and carcass characteristics of broiler chickens. Totally 120 chickens (60 of hybrid Hybro, 60 of Ross 308) were divided to two groups. Experimental chickens of Hybro (n=30) and Ross 308 (n=30) received a probiotic preparation in drinking water from day 1 to day 42 with concentration of 2x109 CFU of Enterococcus faecium M 74 in 1 g of nutrient medium with dextrose. The control group of Hybro (n=30) and Ross 308 (n=30) received water in same total amount as experimental group without any additives. The feeding period lasted 42 days. In case of Hybro, we showed higher effect of Enterococcus faecium M74 supplementation on slaughter weight (1807.51 vs. 1929.08 g; P0.05). Differences in percentage of valuable parts (thigh and breast) and carcass yield of Hybro and Ross 308 were not statistically significant (p>0.05) by addition of probiotic On the end of fattening, Ross 308 broiler chickens fed diet with probiotic strain Enterococcus faecium had significantly less (p0.05).
