摘　　要：文章旨在研究用蚕豆完全替代豆粕并补充复合酶对肉鸡生长性能、屠宰性能及消化道发育的影响。试验将1日龄平均体重一致的552只商品肉仔鸡随机分为3组,每组4个重复,每个重复46只。对照组肉鸡饲喂玉米-豆粕型日粮,豆粕组饲喂玉米-豆粕型日粮+100 mg/kg复合酶,蚕豆组饲喂玉米~蚕豆型日粮+100 mg/kg复合酶。结果 :豆粕组肉鸡42 d体重显著高于蚕豆组(P <0.05),但对照组22~42 d平均日采食量显著低于蚕豆组(P <0.05)。蚕豆组22~42 d肉鸡料重比显著高于对照组(P <0.05),同时蚕豆组1~42 d肉鸡料重比显著高于对照组和豆粕组(P <0.05)。蚕豆组肉鸡的腹脂相对重量显著高于对照组和豆粕组(P <0.05),而对照组肉鸡腹脂相对重量显著高于蚕豆组(P <0.05)。蚕豆组肉鸡腺胃和肌胃相对重量显著高于对照组(P <0.05),但胰腺相对重量显著降低(P <0.05)。蚕豆组肉鸡小肠相对长度显著高于豆粕组(P <0.05)。结论 :在本研究条件下,肉鸡日粮用蚕豆替代豆粕补充100 mg/kg复合酶可以提高肉鸡生长后期的采食量,但降低了饲料效率,对屠宰性能及组织器官的发育无负面影响。This experiment was conducted to study the effects of completely replacing soybean meal with broad bean and supplementing compound enzyme on growth performance,slaughter performance and digestive tract development of broilers. A total of 552 commercial broilers with the same 1-day average body weight were randomly divided into 3 groups with 4 replicates per group and 46 broilers per replicate. Broilers in control group were fed corn-soybean meal type diet,those in soybean meal group were fed corn-soybean meal type diet +100 mg/kg compound enzyme,and those in faba bean group were fed corn-soybean type diet +100 mg/kg compound enzyme. Results :The body weight of broilers on 42 days in soybean meal group was significantly higher than that in broad bean group(P < 0.05),but the average daily feed intake in the control group on 22 ~ 42 days was significantly lower than that in broad bean group(P < 0.05). The feed to gain ratio of broilers in faba bean group was significantly higher than that in control group at 22 ~ 42 days(P < 0.05),and the feed to gain ratio of broilers in faba bean group at 1 ~ 42 days was significantly higher than that in control group and soybean meal groups(P < 0.05).The relative weight of abdominal fat of broilers in broad bean group was significantly higher than that in control group and soybean meal group(P < 0.05),while the relative weight of abdominal fat of broilers in control group was significantly higher than that in broad bean group(P < 0.05). The relative weight of proventriculus and gizzard of broilers in broad bean was significantly higher than that in control group(P<0.05),but the relative weight of pancreas was significantly decreased(P<0.05).The relative length of small intestine of broilers in broad bean group was significantly higher than that in soybean meal group(P< 0.05). Conclusions :Under the condition of this study,supplementation of 100 mg/kg compound enzyme with broad bean instead of soybean meal can improve feed intake of broilers at later growth stage,but reduce feed e
