饲粮中添加棉油和赖氨酸对断奶仔猪生长性能影响的探讨

The Preliminary Study about the Effect of cotton Oil and Lysineof Diet on Performance of weanling pig

在CPl8%水平下,在不添加油脂和添加3%棉油的日粮中各自分别添加0.15%和0.3%赖AA,形成4种日粮,进行饲养试验,探讨对断奶仔猪生长性能的影响.3Od饲养试验表明:不添加棉油日粮日增重明显高于棉油日粮,组间差异极显著(P<0．01);添加0.15%与0.30%赖AA日粮,组内差异不显著(P>0.05).试验期间各组腹泻次数不多.说明此阶段CPl8%水平下,以不添加加棉油且赖AA为1.15%更适宜.

In CP18% level,each of two kind of basic diets that didn't Contain Cotton oil or Contain 3% Cotton oil append 0.15% or 0. 30% lysine respectively,forming four kind of diets and a feeding trial was carried to study the effect of Cotton oil and lysine on performance of weanling pig. The result showed that daily gain of the groups that didn't Contain Cotton oil Were higher than the groups Containing Cotton oil obviously and have significant difference (p<0. 01), but the group appending 0. 15% Lysine and the group appending 030% Lysine have not significant difference (P>0. 05). The exper iment showed that diet that didn't Contain cotton oil and lysine level was 0.15% was suitable in CP 18% level.
