【摘要】 为观察微丸型复合酶不同添加水平对乳、仔猪生产性能的影响,选取16头母猪所产160头“杜长大”三元杂交乳猪进行Ⅰ(16 d),Ⅱ(10 d),Ⅲ(35 d)共3期饲养试验.试验设4个处理,每处理4次重复,每重复10头.试验1,2,3组分别饲喂在基础日粮中添加150,180和200 g/t微丸型复合酶的日粮,对照组不添加.结果表明:在乳猪诱食的试验Ⅰ期,复合酶的作用不明显;在试验Ⅱ,Ⅲ期,加酶各组与对照组日增重和采食量差异均不显著(P>0.05),但有提高趋势,其中以添加180 g/t复合酶的试验2组最高;试验Ⅱ,Ⅲ期加酶各组的腹泻率比对照组在两个试验期均显著降低(P<0.05).在试验Ⅲ期,试验2,3组血液的血糖、碱性磷酸酶和胰岛素含量显著高于对照组(P<0.05),与对照组相比,加酶组的血液尿素氮含量下降,淀粉酶活性上升,但差异未达显著水平(P>0.05).微丸型复合酶对乳猪诱食与生长效果的影响不明显,在仔猪日粮中添加量150 g/t是有效的,但以添加180 g/t更为适宜.更多还原

【Abstract】 The effects of different levels of compound enzyme preparation’s(CEP) supplementation on performance and some biochemical parameters of blood of piglets were researched.The feeding trial selected 160 crossbred“Duroc× Landrace×Yorkshire” piglets from 16 litters to carriy on three phases(16 d,10 d,and 35 d for phase Ⅰ,Ⅱ,Ⅲ) of raising experiments.There were four treatments,and every treatment included four replicates of ten.The controlled group was fed basic diet,and experiment group 1,experiment group 2,and experiment group 3 were added enzyme preparation 150 g/t,180 g/t,and 200 g/t in basic diet respectively.The results showed that the effect of CEP to tempted piglets was not obvious in the first phase;In the second and third phase,ADG and F/G tended to be improved the group supplemented with 180 g/t compound enzyme preparation had the highest ADG and lowest F/G than other groups,but there was no significant difference(P>0.05);Compared to the controlled group,Diarrhea rate of the piglets supplemented with CEP significantly decreased(P<0.05);Glucose,alkaline phosphatase,and insulin of blood in experiment group 2 and experiment group 3 were higher than those of the controlled group(P<0.05),Supplemented CEP decreased urea nitrogen of blood and improved amylase of blood,but there was no significant difference(P>0.05).The study suggested that dietary CEP’s supplementation has no effect on intake and growth for sucking piglets,but for piglets,added enzyme preparation 150 g/t in basic diet could improve performance,and the optimal supplementation level was 180 g/t.更多还原
