选取健康、体重相近的15日龄双鬼头肉鸭480只,随机分成4个组,每个组6个重复,每个重复20羽,分别饲喂木薯添加量为0、10%、20%和30%的试验日粮,进行为期30 d的试验。结果表明:①随着木薯添加量的增加,肉鸭平均日采食量逐渐上升,30%木薯组显著高于10%木薯组(P﹤0.05),而肉鸭日增重呈现先上升后下降的趋势,其中20%木薯组的45日龄重(末重)和平均日增重均与对照组差异显著(P﹤0.05),当木薯添加量为20%时肉鸭增重效果最佳,料重比最低;②当木薯添加量为10%和20%时,日粮干物质表观消化率和表观代谢能显著高于其他2组(P﹤0.05),且有提高蛋白质表观消化率的趋势;除甘氨酸、精氨酸、苏氨酸、脯氨酸、缬氨酸和...

To investigate the effect of cassava on growth performance and nutrient utilization of meat ducks,a total of 480 meat ducks aged 15 d were randomly allotted to four treatments with six replicates in each treatment and each replicate containing 20 ducks.The four treatments were fed with the diet supplemented with 0,10%,20%,30% cassava respectively for 30 d.The results showed： ① With the increasing of cassava,the average daily feed intake was gradually increased,and the average daily feed intake in the treatment with 30% cassava was significant...
