摘要
选择35d龄断奶体重约9kg的长大二元杂交仔猪24头,随机分成2组,研究添加复合酶制剂对生长猪生产性能的影响。选择体重35~40kg6头阉公猪采用全收粪法进行消化试验,研究复合酶制剂对日粮养分表观消化率的影响。结果表明,添加酶制剂能显著提高生长猪的的生产性能和日粮养分的表观消化率,与对照组相比,日增重提高8.29%(P<0.05),饲料转化率提高8.89%(P<0.05),粗纤维表观消化率提高36.76%(P<0.01),粗蛋白质表观消化率提高17.23%(P<0.01),干物质表观消化率提高9.75%(P<0.01)。
crossing piglets,35 days of age and about 9 kg in weight,were selected to study the
effects of complex enzyme on performance of growing pigs. 6 barrows of 3540 kg in weight
were selected to carry out digestible experiment in order to study the effects of the complex
enzyme on nutrient digestibility in the diet.The results showed that both the performance of
growing pigs and the nutrient apparent digestibility in the diet were significantly improved when
the complex enzyme was added into the basic diet.Compared with the control group,weight gain
(P<0.05),feed conversion efficiency(P<0.05),the apparent digestibility of crude fiber ( P
<001),protein ( P <001)and crude dry matter ( P <001) were increased by
8.29%,8.89%,36.76%,17.23%,9.75% respectively.
