Effect of Soybean Meal Replaced by Fermented Rapeseed Meal on Growth Performance, Meat Quality and Serum Biochemical Indexes of Broilers
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 ％.
