| 摘 要： | 本研究旨在分析日粮添加不同比例的发酵菜籽粕对白羽公番鸭生长性能和血液指标的影响。将480只同批次、体重相近的28日龄健康白羽公番鸭随机分成4组,每组6个重复,每重复20只。对照组饲喂玉米-豆粕型基础日粮,试验组分别用12%、16%和20%的发酵菜籽粕等氮代替基础日粮中的豆粕,试验期为期21 d。结果表明:1)对照组和16%组番鸭的末体重和平均日增重显著高于其他各组(P<0.05),对照组番鸭的平均日采食量显著高于其他各组(P<0.05)。2)16%组番鸭血清总蛋白、总胆固醇、高密度脂蛋白和低密度脂蛋白含量均显著低于12%组(P<0.05);16%组番鸭血清的谷丙转氨酶活性和碱性磷酸酶活性显著高于12%组(P<0.05),而血清甲状腺激素含量则相反。3)16%组番鸭血清的超氧化物歧化酶活性均显著低于对照组(P<0.05),而其他指标无显著性差异。以上结果显示,日粮中适当添加发酵菜籽粕替代豆粕不会影响番鸭的生长性能,其中添加16%的效果较好。

| Abstract: | To study the effects of supplementing diet with varying doses of fermented rapeseed meal on growth and serum indices in white male muscovy ducks,four-hundred and eighty 28-day-old white male muscovy ducks all of the same hatching cohort and of similar body weight were randomly divided into 4 groups,with 6 replicate subgroups of 20 ducks each.Ducks in the control group were fed a corn-soybean basal diet.Ducks in the experimental groups were fed the basal diet supplemented with 12%,16%,or 20%fermented rapeseed meal.The experimental period was 21 days.The results are as follows:1)the final body weight and average daily weight gain in the control group and the 16%group were significantly higher than those in the other groups(P<0.05).The average daily feed intake in the control group was significantly higher than that in the other groups(P<0.05).2)Serum total protein,total cholesterol,high-density lipoprotein,and low-density lipoprotein were significantly lower in the 16%group than in the 12%group(P<0.05).Alanine transaminase and alkaline phosphatase activities were significantly higher in the 16%group than in the 12%group(P<0.05),but tetraiodothyronine concentrations displayed an opposite trend.3)Superoxide dismutase activity was significantly lower in the 16%group than in the control group(P<0.05).No significant differences were observed in other indices of antioxidant functions.In conclusion,fermented rapeseed meal can be added to the diet without negatively impacting the growth performance of ducks.Supplementation with 16%fermented rapeseed meal had good efficacy in this study. |
