摘　　要：为研究湿鲜发酵豆粕替代豆粕对快大型黄羽肉鸡生长性能、胴体品质和抗氧化能力的影响,选取720只1日龄快大型黄羽肉公雏[初始体重(41.83±0.02)g],采用完全随机区组分为4个处理,每个处理6个重复,每个重复(栏)30只鸡。试验期55 d(1~25日龄和26~55日龄)。对照组饲喂基础日粮,试验组按照湿鲜发酵豆粕1.2:1替代豆粕,在基础日粮中分别添加2%、4%和12%湿鲜发酵豆粕。试验结束时每组随机选取6只鸡屠宰,采集胸肌、腿肌、脏器、血清及空肠黏膜等样本进行分析。结果表明:添加湿鲜发酵豆粕对黄羽肉鸡日增重无显著影响,1~25日龄,4%添加组料重比与对照组相比降低3.31%(P<0.05),26~55日龄,12%添加组和4%添加组肉鸡平均日采食量分别较对照组提高5.46%和3.98%(P<0.05)。12%添加组肉鸡腿肌率较对照组降低4.29%。12%添加组宰后45 min胸肌pH较对照组降低3.83%(P<0.05)。4%添加组和12%添加组总抗氧化能力分别较对照组降低45.09%和38.22%(P<0.05),2%添加组与对照组总抗氧化能力无显著差异。添加湿鲜发酵豆粕在一定程度上增加了适口性,采食量增加,本试验条件下,湿鲜发酵豆粕4%添加较为合适。This experiment was conducted to investigate the effects of different proportions of wet-fresh fermented soybean meal supplementation on growth performance,carcass quality and antioxidant capability in yellow-feathered broilers.A total of 720 one-day-old yellow feathered male chicks [initial body weight(41.83±0.02)g]were randomly divided into 4 treatments with 6 replicates per treatment and 30 chickens per replicate(pen).The experiment lasted for 55 days(1 to 25 days of age and 26 to 55 days of age).Broilers in the control group were fed a basal diet,and those in the experimental groups were fed the basal diet supplemented with 2%,4% and 12% wet fermented soybean meal,respectively,in which wet fermented soybean meal replaced soy-bean meal at a ratio of 1.2:1.At the end of the experiment,6 chickens were randomly selected for slaughter in each group,and the samples of organs,serum and jejunum mucosa were collected for analysis.The results showed as follows:There were no significant differences in average daily gain among all groups.From 1 to 25 days of age,the ratio of feed to gain in 4% added group was decreased by 3.31%compared with the control group(P < 0.05).From 26 to 55 days of age,the average daily feed intake of broilers in 12% group and 4% group was increased by 5.46% and 3.98% compared with the control group,respectively(P < 0.05).The leg muscle percentage in 12% group was 4.29% lower than the control group.The chest muscle pH45 minin 12% group was 3.83% lower than the control group(P < 0.05).The total antioxidant capacity of 4% and 12% supplemental groups was decreased by 45.09% and 38.22% compared with the control group,respectively(P < 0.05),and the total antioxidant capacity of the 2% group was not significantly different from the control group.Adding wet-fresh fermented soybean meal increased palatability and feed intake to a certain extent.In this experiment,4% of wet-fresh fermented soybean meal was the appropriate ratio.
