Abstract
Two hundred and eight one-day broiler chicks (ROSS 500) were divided into 4 treatments till 35 days old, each group fed on corn-soybean starter diet (S) from 1-21 days old and grower diet (G) from 22-35 days old. Control treatment received un-supplemented S and G diets, S1G0 group fed on S supplemented with 1 g Bio-Mos kg-1 then un-supplemented G, S1G0.5 group received S supplemented with 1 g Bio-Mos kg-1 then G supplemented with 0.5 g Bio-Mos kg-1, while , S1G1 group received S supplemented with 1 g Bio-Mos kg-1 then G supplemented with 1 g Bio-Mos kg-1. Each treatment included 52 chicks which reared on two batteries. During the 35 days of experimental period, a significant improvement in Body Weight Gain (BWG), Feed Conversion Ratio (FCR), microbial population counts and some histological alterations of small intestine, besides, a significant decreasing in feed cost per kilogram BWG (FCO) and higher Economic Efficiency Index (EEI) were showed with supplemented groups compared with un-supplemented treatment. Using of 1 g Bio-Mos kg-1 of starter diet in all supplemented diets and increasing of Bio-Mos in grower diet by 0, 0.5 or 1 g resulted in the followings: I-0.5 g kg-1 rate showed the highest BWG and FI and lowest ceacal E. coli count among treatments. g kg-1 rate recorded the best FCR, higher jejunal and ileal villus length, ceacal Lactobacillus and lower count of ceacal Salmonella. III-Linear reduction in FCO and increasing in EEI values up to 1 g kg-1 rate with Bio-Mos increasing but difference between treatments was not significant.
