日粮中添加酶制剂对断奶仔猪生产性能及消化率的影响

以 60头 3 5日龄长白断奶仔猪为试验动物 ,在玉米 /豆粕基础日粮中添加 0 0 5 % ,0 10 % ,0 15 %的酶制剂 ,结果表明 ,0 10 %酶制剂添加水平对断奶仔猪生产性能和日粮养分的消化率及添加剂的经济效益达到最大值。

Effect of enzyme preparation and adding level on weanling piglets performance and digestive rate

Sixty Landrace 35-days weanling piglets were fed with corn-soybean based diet adding enzyme difference preparation levels(0%,0 05%,0 10%,0 15%)to observe the effect of enzyme and adding level on weanling piglets performance and nutrition digestive rate There was significant change trend between enzyme preparation level ADG,feed/gain,nutrients digestive rate The different adding levels of enzyme preparation may promove ADG for weanling piglets The enzyme preparation for 0 10% and 0 15% levels significantly increase weanling piglets ADG( P <0 01),but 0 15% enzyme preparation level tended to have decreased ADG compared with 0 10% enzyme preparation level ( P <0 01) There was no difference between 0 05% enzyme preparation level group and control guoup for weanling piglets ADG There were same change trend about feed/gain and digestive rate compared with ADG In this experiment,0 10% enzyme preparation level has improved ADG?feed effecience and nutrients digestive rate at same time
