【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）。更多还原

【Abstract】 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.更多还原
