【摘要】 选择体重8kg左右的长白仔猪30头,随机分成3组,其中对照组喂基础日粮,试验Ⅰ、Ⅱ组在基础日粮中分别添加0.1%、0.2%的复合酶制剂,研究添加复合酶制剂对仔猪生产性能和日粮养分消化率的影响。结果表明:试验Ⅰ组猪的生产性能和消化率与对照组相比差异不显著;而试验Ⅱ组与对照组相比,日增重、饲料转化率分别提高19.19%(P<0.01)和26.92%(P<0.01),差异极显著。日粮干物质(DM)、粗蛋白质(CP)、粗纤维(CF)和粗脂肪(CE)的消化率分别提高10.05%(P<0.01)、6.04%(P<0.05)、20.50%(P<0.01)和6.34%(P<0.05),差异显著。更多还原

【Abstract】 The test chooses 30 landrace piglets weighing about 8 kg,which are divided into 3 groups with random.Control group feed basic dietary,groupⅠand group Ⅱ respectively add enzyme preparation 0.1% and 0.2% in basic dietary.While choice 5 clean pig from every group carry out digest test with method of interior indicator,research enzyme preparation affect piglet productivity and digestion rate of dietary nutrients respectively.Comparing with the control group,groupⅠ is no significantly. Then group Ⅱcould significantly improve(P<0.01) the daily gain and feed conversion,respectively increasing 19.19% and 26.29%,the digestibilities of DM、CP、CF and CE respectively increasing 10.05%(P<0.01)、6.04%(P<0.05)、20.50%(P<0.01) and 6.34%(P<0.05).更多还原
