不同复合酶对断奶仔猪生产性能和饲料养分利用率影响的比较研究

选用25～27日龄断奶的"长×大"二元杂交断奶仔猪96头平均体重为(7.31±0.14)kg],以研究不同复合酶对断奶仔猪生产性能和饲料养分消化率的影响。试验仔猪按完全随机区组设计分为4个处理,每个处理3个重复,每个重复8头仔猪,试验期14 d。对照组饲喂基础日粮,试验组A、B、C在基础日粮中分别添加不同的复合酶A、B、C。试验结果表明:基础日粮中添加复合酶A、B、C后,断奶仔猪的平均日增重分别提高了7.58%(P<0.05)、10.15%(P<0.05)和5.74%(P<0.05),料重比分别降低了5.47%(P<0.05)、8.59%(P<0.05)和6.25%(P<0.05),有机物、粗蛋白和磷的消化率显著提高(P<0.05),粗蛋白的消化率分别提高了2.96%、3.3%和2.26%。在3种复合酶中,以复合酶B的效果为最好,其次为复合酶A和C。

Research on the effect of different compound enzymes on growth performance and nutrient digestibility in weaned piglet

To study the effect of different compound enzymes on the growth performance and feed nutrient digestibility,a two-week feeding trial was done with 96 25～27 day-old weaned "L×Y" piglets average bodyweight:(7.31±0.14) kg] and randomly allocated to four dietary treatments consisting of 3 replicates of 8 piglets each.The four treatmets were fed with basal diet,basal diet +compound enzyme A,basal diet +compound enzyme B,basal diet +compound enzyme C,respectively.The result showed that the average daily gain increased 7.58%(P<0.05),10.15%(P<0.05),and 5.74 %(P<0.05),ratio of feed to gain reduced 5.47%(P<0.05),8.59%(P<0.05),and 6.25%(P<0.05) compared to the control.The organism matter,crude protein and phophate degestibility were significantly increased(P<0.05),the crude protein degestibility was increased to 2.96%,3.3%,and 2.26% respectively compared to the control,the effect of compound enzyme B was the best in the three compound enzymes.
