Abstract: This study was aimed to investigate the effects of lactic acid bacteria (LAB) on the growth performance, nutrient apparent digestibility and slaughter performance of broilers fed diets contaminated with AFB1.A total of 240 male AA broilers at one day old were randomly allotted into 4 groups with 6 replicates per group and 10 chicks per replicate.Positive control group, no AFB1 in the diet;Negative control group, 1-21 d, positive control group diet+40 μg/kg AFB1, 22-42 d, positive control group diet+80 μg/kg AFB1;LAB group, negative control diet+1.5×1011 CFU/kg LAB;HSCAS group, negative control diet+3 g/kg HSCAS.The trial lasted for 42 days.The results showed that the average daily feed intake and body weight gain in negative control group were significantly decreased (P<0.05), and F/G was significantly increased (P<0.05), and the diets supplemented with LAB or HSCAS could significantly improved the growth performance (P<0.05), and the LAB had better effects than HSCAS.Comparing with negative group at 1 to 21 days, the nutrient apparent digestibility of DM, energy, EE, Ca and P were increased by 9.6% (P<0.05), 9.5% (P<0.05), 10.1% (P<0.05), 15.2% (P<0.05) and 18.9% (P<0.05) in LAB group, respectively.Whereas the nutrient apparent digestibility of DM, energy, EE and P were increased by 9.7% (P<0.05)、6.6% (P<0.05)、6.3% (P<0.05) and 17.4% (P<0.05) in HSCAS group, respectively.And the nutrient apparent digestibility of energy, Ca, eviscerated yield percentage and breast muscle percentage in LAB group were significantly higher than that in HSCAS group (P<0.05).LAB used in the present trial could significantly improved the growth performance, nutrient apparent digestibility and slaughter performance of broilers fed diets contaminated with AFB1, and had better effects than HSCAS.

Key words: aflatoxin; lactic acid bacteria; broiler; growth performance; nutrient apparentdigestibility; slaughter performance
