摘要
选择22日龄商品代番鸭180只,研究在高米糠粕日粮中添加酶制剂对其生长性能的影响。结果表明:添加0.1%酶制剂使番鸭日增重提高10.83%(P<0.01),饲料利用率提高10.35%(P<0.01),肝重率提高16.87%(P<0.01),腹脂率降低10.38%(P>0.05)。添加酶制剂有利于番鸭羽毛生长,防止啄羽,试验第2、第3周加酶组啄羽率比对照组均下降50%。
One hundred and eighty commercial muscovy ducks (22 day old) were used to study the effects of high solvent rice bran meal diets supplemented enzyme additive on growth performance.The results were as follows,compared with the control group,daily gain, feed efficiency and dissected liver weight ratio of ducks fed with high solvent rice bran meal diets supplemented enzyme additive were increased by 10.83%(P〈0.01),10.35%(P〈0.01) and 16.87%(P〈0.01)respectively,dissected abdominal fat rate was decreased by 10.38% (P〉0.05 ).During the second and third experimental weeks,feather pecking rate of ducks fed with high solvent rice bran meal diets supplemented enzyme additive were both decreased by a same percentage of 50.0%.
