Effects of Fermented Soybean Meal in Different Levels on Performance in Broilers

A total of 240 AA chickens at 1-day-old were randomly divided into 4 groups,and each group had 6 replications(10 broilers per replication).The control group was fed with corn-soybean meal diet,and the treatment groupsⅠ,Ⅱand Ⅲ were formulated by adding fermented soybean meal 5%,10%,15%,respectively.Ex-periment periods were 42 d.The results showed that comparing with the control,the average daily gain(ADG)of groupsⅠ,Ⅱand Ⅲ were significantly increased by 14.13%,14.55%,10.13%(P 0.01),respectively;the average daily feed intake(ADFI)of groupsⅠ,Ⅱand Ⅲ were increased by 6.24%(P 0.01),4.81%(P 0.01),3.88%(P0.05);the feed/gain was significantly decreased by 7.03%,8.65%,5.94%(P 0.01).Therefore,the best effect is 10% fermented soybean meal supplement.
