摘 要：
试验旨在研究α-1,4-淀粉酶、普鲁兰酶和糖化酶组合对肉鸡生长性能、肠道形态和屠宰性能的影响。选取1 960羽1日龄健康罗斯308肉仔鸡,随机分为7个处理,每个处理4个重复,每个重复70羽。对照组饲喂基础饲粮,试验1组在基础饲粮中添加1 800 IU/kgα-1,4-淀粉酶,试验2组在基础饲粮中添加180 IU/kg普鲁兰酶,试验3组在基础饲粮中添加135 000 IU/kg糖化酶,试验4组在基础饲粮中添加1 800 IU/kgα-1,4-淀粉酶+135 000 IU/kg糖化酶,试验5组在基础饲粮中添加1 800 IU/kgα-1,4-淀粉酶+180 IU/kg的普鲁兰酶,试验6组在基础饲粮中添加1 800 IU/kgα-1,4-淀粉酶+135 000 IU/kg糖化酶+180 IU/kg普鲁兰酶。结果表明:与对照组相比,试验6组1～21日龄和22～42日龄阶段末重、日增重显著提高(P<0.05),22～42日龄阶段试验1、2、3、4、6组耗料增重比(FCR)显著下降(P<0.05);试验3组空肠绒毛高度/隐窝深度(VH/CD)显著高于对照组(P<0.05)和试验1组(P<0.05);试验1、4组回肠VH/CD显著高于对照组(P<0.05);各组间屠宰性能差异不显著。试验结果表明,α-1,4-淀粉酶、糖化酶和普鲁兰酶在肉鸡体内存在互作效应,α-1,4-淀粉酶、糖化酶和普鲁兰酶组合添加对肉鸡的促生长效果优于单一类型淀粉酶。

摘 要：
This research was to study the effects of α-amylase, pullulanase and glycosylase added in different combinations on the growth performance, intestinal morphology and slaughter performance of broilers. 1 960 healthy ROSS 308 broilers were chosen and randomly divided into 7 groups, namely, the control group and test groups 1～6,with each group in 4 replicates(n=70). The control group was fed with the basal diet; Test group 1 was fed with the basal diet supplemented withα-amylase 1 800 IU/kg, Test group 2 with the basal diet supplemented with pullulan enzyme 180 IU/kg, Test group 3 with the basal diet supplemented with glycosylase 135 000 IU/kg, Test group 4 groups with the basal diet supplemented with α-amylse 800 IU/kg+glycosylase 135 000 IU/kg, Test group 5 with the basal diet supplemented with α-amylse 1 800 IU/kg+180 IU/kg of pullulan enzymes, and Test group 6 with the basal diet supplemented with α-amylase 1 800 IU/kg+glycosylase 135 000 IU/kg+pullulanase 180 IU/kg. The results showed as follows: In terms of growth performance, compared with the control group, the final body weight and average daily gain(ADG) of Test group 6 was significantly increased(P<0.05), during the stage of 22 ～ 42 days of age, the consumed material/weight ratio(FCR) of Test groups 1, 2, 3, 4, 6 decreased significantly(P<0.05). In terms of intestinal morphology, the jejunum VH/CD of Test group 3 was significantly higher than that of the control group(P<0.05) and Test group 1(P<0.05), and the ileum VH/CD of Test groups 1 and 4 was significantly higher than that of the control group(P<0.05). In terms of slaughter performance, there was no significant difference between each of the groups. In conclusion, α-amylase, pullulan enzyme and glycosylase interacted with each other in a supplementary manner, and combinations of them added to the diet of broilers produced better effect
