摘要: 本试验旨在研究发酵菜籽粕替代豆粕对肉鸡生长性能、肉品质及血清生化指标的影响。选用23日龄黄羽肉公鸡400只,随机分为4组,每组4个重复,每个重复25只,对照组饲喂基础日粮,试验Ⅰ、Ⅱ和Ⅲ组分别在基础日粮中添加3%、6%和9%发酵菜籽粕等营养替代豆粕。试验期43 d。结果表明:①与对照组相比,试验Ⅰ、Ⅱ和Ⅲ组肉鸡平均日增重、平均日采食量和料重比差异均不显著(P>0.05);与试验Ⅰ、Ⅱ组相比,试验Ⅲ组肉鸡平均日增重分别提高16.47%(P<0.05)、15.03%(P<0.05),料重比分别降低7.71%(P<0.05)和4.27%(P>0.05)。②各组肉鸡胸肌的pH1、pH24、肉色(L*、a*、b*)、蒸煮损失和嫩度差异均不显著(P>0.05);试验Ⅰ、Ⅱ和Ⅲ组肉鸡胸肌的失水率与对照组相比均显著降低(P<0.05)。③与对照组相比,试验Ⅰ、Ⅱ和Ⅲ组肉鸡血清中葡萄糖含量分别降低13.06%(P<0.05)、8.12%(P>0.05)和9.57%(P>0.05);总蛋白含量分别提高2.50%(P>0.05)、20.86%(P<0.05)和33.92%(P<0.05);谷丙转氨酶含量分别降低7.99%(P>0.05)、18.85%(P>0.05)和26.98%(P<0.05)。综上所述,肉鸡日粮中添加3%~9%发酵菜籽粕等营养替代豆粕是可行的,其中添加9%发酵菜籽粕效果最好。

Abstract: This experiment was conducted to study the effect of soybean meal replacement by fermented rapeseed meal on growth performance,meat quality and serum biochemical indexes of broilers.A total 400 23-day-old Yellow-feathered male broilers were randomly divided into 4 groups with 4 replicates per group and 25 broilers per replicate.The broilers in control group were fed a basal diet,and the others were fed the basal diets with the 3% (group Ⅰ),6% (group Ⅱ) and 9% (group Ⅲ) fermented rapeseed meal equal-nutritionally replacing the soybean meal,respectively.The experiment lasted for 43 days.The results showed as follows:① Compared with control group,the ADG,ADFI and F/G of groups Ⅰ,Ⅱ and Ⅲ showed no significant differences (P>0.05);The ADG of group Ⅲ were 16.47% (P<0.05),15.03% (P<0.05) higher than that of groups Ⅰ and Ⅱ,the F/G of group Ⅲ were 7.71% (P<0.05),4.27% (P>0.05) lower than that of groups Ⅰ and Ⅱ.② There were no significant differences in the pH1,pH24,meat color (L*,a*,b*),cooking loss and tenderness of chest muscle among all groups(P>0.05);Compared with control group,the water loss rate of groups Ⅰ,Ⅱ and Ⅲ were significantly decreased (P<0.05).③ Compared with control group,the serum GLU content of groups Ⅰ,Ⅱ and Ⅲ were decreased by 13.06%(P<0.05),8.12%(P>0.05) and 9.57%(P>0.05);The serum TP content of groups Ⅰ,Ⅱ and Ⅲ were increased by 2.50%(P>0.05),20.86%(P<0.05) and 33.92%(P<0.05);The serum GPT content of groups Ⅰ,Ⅱ and Ⅲ were decreased by 7.99%(P>0.05),18.85%(P>0.05) and 26.98%(P<0.05).It was concluded that it would be feasible to replace the soybean meal with 3% to 9% fermented rapeseed meal in broiler feeding,and the optimum supplemental level of fermented rapeseed meal was 9%.
