摘　　要：文章旨在评估日粮添加不同水平的香蕉加工残渣对肉鸡生长性能、养分消化、肉品质及经济效益的影响。试验将平均体重一致的540只1日龄肉鸡随机分为3组,每组5个重复,每个重复36只,在整个1~42d的试验期,对照组肉鸡饲喂基础日粮(香蕉加工残渣水平为0%),T1和T2组肉鸡饲喂香蕉加工残渣添加水平分别为10%和20%的日粮。结果:10%香蕉加工残渣组肉鸡42d体重较对照组显著提高3.59%(P<0.05),但1~42d料重比显著降低3.28%(P<0.05)。与对照组相比,10%和20%香蕉加工残渣组22~42d肉鸡的平均日增重分别显著提高5.25%和3.28%(P<0.05),而22~42d肉鸡的料重比分别显著降低4.82%和3.01%(P<0.05)。与对照组相比,10%和20%香蕉残渣组肉鸡有机物表观消化率显著提高3.81%和4.19%(P<0.05),同时10%香蕉残渣组肉鸡粗蛋白质表观消化率显著提高3.40%(P<0.05)。与对照组相比,10%和20%香蕉加工残渣组肌肉硫代巴比妥酸反应物浓度显著降低(P<0.05),肌肉系水力和蛋白硫醇含量显著升高(P<0.05)。经济效益分析结果显示,10%香蕉加工残渣组肉鸡单公斤的增重成本较对照组显著降低5.08%(P<0.05)。结论:日粮添加香蕉加工残渣提高了肉鸡生长后期的日增重和饲料效率,同时改善了有机物表观消化率及肌肉系水力,综合考虑生产饲料成本,1~42d肉鸡日粮中香蕉加工残渣适宜的添加水平为10%。This experiment was conducted to evaluate the effects of different banana processing residues on growth performance,nutrient digestion,meat quality and economic benefits of broilers.A total of 5401-d broilers with the same average body weight were randomly divided into 3 groups with 5 replicates per group and 36 broilers per replicate.Broilers in the control group were fed a basal diet(0%banana processing residue),and broilers in the T1 and T2 groups were fed diets supplemented with 10%and 20%banana processing residue,respectively,during the whole 1~42 d experiment period.Results:Compared with the control group,the body weight of broilers in 10%banana processing residue group on 42 d was significantly increased by 3.59%(P<0.05),but the feed/gain of broilers in 10%banana processing residue group on 1~42 d was significantly decreased by 3.28%(P<0.05).Compared with the control group,the average daily gain of broilers in 10%and 20%banana processing residue groups during 22~42 d was significantly increased by 5.25%and 3.28%(P<0.05),respectively,while the feed/gain of broilers during 22~42 d was significantly decreased by 4.82%and 3.01%(P<0.05).Compared with the control group,the apparent digestibility of organic matter of broilers in 10%and 20%banana residue groups was significantly increased by 3.81%and 4.19%(P<0.05),and the apparent digestibility of crude protein of broilers in 10%banana residue group was significantly increased by 3.40%(P<0.05).The concentration of thiobarbituric acid reactants was significantly decreased(P<0.05).Economic benefit analysis showed that the concentration of muscle system water and protein mercaptan in 10%and 20%banana processing residue groups were significantly higher than those in control group(P<0.05),but the weight gain cost per kg of broilers in 10%banana processing residue group was significantly decreased by 5.08%(P<0.05)compared with that in control group.Conclusions:Dietary supplementation of banana processing residue can improve the daily gain and feed efficiency of broilers
