An experiment was conducted to investigate the effects of Bacillus amyloliquefaciens LFB112 in the diet on growth of broilers and on the quality and fatty acid composition of broiler meat.4401-day-old Arbor Acres male broiler chicks were randomly allocated into five dietary treatments with eight replicates in a completely randomised design for 42 *** treatments were as follows:basal diet(control) or the basal diet supplemented with 10～7 CFU(Colony-Forming Units) ***/kg(B7),10～8 CFU ***/kg(B8),10～9 CFU ***/kg(B9) or 40 mg aureomycin/kg(antibiotic).The results showed that ***-sapplemented groups had greater(P < 0.05) average daily gain during Days 1 to 21,Days 22 to 42 and Days 1 to 42,and improved(P < 0.05) feed conversion rate during Days 1 to 42 compared with the *** in the B7 and B9 groups had higher(P < 0.05) average daily feed intake than those in the control group in all experimental *** fed either *** or antibiotic diet showed higher(P <0.05) a* value,b* value and lower L* value in the breast muscle than those in the control *** *** supplementation increased(P < 0.05) the contents of C14:l,C16:lc,C18:1 t,C18:1 c,C20:1 n-9,total monounsaturated fatty acids,C18:2 c,C18:3 n-3,C20:2 n-6,C20:3 n-6,C20:3 n-3,C20:4 n-6,C20:5 n-3,C22:6 n-3 and total polyunsaturated fatty acids as well as ratio of polyunsaturated fatty acids to saturated fatty acids in breast muscle and the concentrations of C17:1,C20:1 n-9,C18:2 t-9,t-12,C20:2 n-6,C20:3 n-6,C20:3 n-3,C20:4 n-6,C20:5 n-3 and C22:6 n-3 in thigh muscle of *** results indicated that *** improved broilers' growth performance,meat quality and fatty acid composition.
