摘要: 本试验旨在探讨日粮中添加外源酶制剂的情况下,不同比例的小麦和发酵芝麻粕对肉鸡生长性能、肉品质及血清生化指标的影响。选用21日龄平均体重为(330±10)g的健康肉鸡(快速)520只,随机分为5组,分别为:对照组(基础日粮)、试验Ⅰ组(20%小麦+5%发酵芝麻粕)、试验Ⅱ组(40%小麦+10%发酵芝麻粕)、试验Ⅲ组(20%小麦+豆粕)、试验Ⅳ组(40%小麦+豆粕),每组4个重复,每个重复26只鸡,以重复为单位单圈饲养,预试期3 d,正试期34 d。屠宰后测定肉鸡生长性能、肉品质和血清生化指标。结果显示,试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组肉鸡平均日增重与对照组相比分别降低了9.40%、7.15%、8.87%、5.46%(P<0.05),平均日采食量和料重比差异均不显著(P>0.05);各试验组对肉鸡肉品质影响与对照组相比均无显著差异(P>0.05),其中试验Ⅱ组肉品质相对于其他各组有所提高;试验Ⅲ、Ⅳ组肉鸡血清中谷丙转氨酶含量与对照组相比分别降低了30.10%、25.36%(P<0.05),各试验组血清中总蛋白、尿素氮和谷草转氨酶含量与对照组相比均无显著差异(P>0.05)。综上所述,在本试验条件下,适当比例的小麦和发酵芝麻粕可替代日粮中部分玉米和豆粕,其中以添加40%小麦+10%发酵芝麻粕效果较好。

Abstract: This study was to investigate the effects of different proportions of wheat and fermented sesame meal on growth performance,meat quality and serum biochemical indexes in broilers under the condition of adding exogenous enzymes in the diet.A total of 520 21-day-old broilers (fast)with an average body weight of (330±10)g were randomly assigned to 5 groups with 4 replicates in each group and each replicate contained 26 broilers. Broilers in the 5 groups were fed experimental diets containing 0 (control group),20% wheat +5% fermented sesame meal (group Ⅰ),40% wheat +10% fermented sesame meal (group Ⅱ),20% wheat + soybean meal (group Ⅲ) and 40% wheat + soybean meal (group Ⅳ),respectively.The pre-test period lasted for 3 days and the trial period lasted for 34 days.The results showed that compared with the control group,the ADG in groups Ⅰ,Ⅱ,Ⅲ and Ⅳ was significantly decreased by 9.40%,7.15%,8.87%,5.46% (P<0.05),respectively,while the ADFI and F/G showed no significant differences (P>0.05).There were no significant differences on meat quality among all experimental groups(P>0.05), respectively, but group Ⅱ had better meat quality than others.Compared with the control group,the content of alanine aminotransferase in serum in groups Ⅲ, Ⅳ was significantly decreased by 30.10%,25.36% (P<0.05),but there were no significant differences in the contents of total protein,urea nitrogen and aspartate aminotransferase in serum in all experimental groups(P>0.05).In conclusion,under the experimental conditions,adding appropriate proportions of wheat and sesame meal could replace part of the corn and soybean meal in the diet,and the better supplementation level of wheat and fermented sesame meal was 40% and 10%,respectively.
