摘要
试验旨在探讨复合酶制剂对以玉米—杂粕为基础日粮的断奶仔猪生长、代谢和血液指标的影响。试验选择48头断奶仔猪,分为2组。试验组在对照组的日粮基础上添加1%复合酶制剂。试验分2个阶段,试验前期(1～21 d)和试验后期(22～50 d)。结果表明,试验前期日增重、料重比、腹泻发生率试验组均优于对照组(P<0.05),试验全程(1～50 d)的日增重、腹泻率和料重比试验组优于对照组,料重比差异显著(P<0.05)。21 d时除粗灰分外,其他养分的消化率试验组均显著高于对照组(P<0.05),50 d时粗脂肪和粗纤维的消化率试验组高于对照组(P<0.05),其它养分的消化率差异不显著。血液生化指标结果显示,21和50 d时试验组的总蛋白和白蛋白均高于对照组,但差异不显著;尿素氮试验组均低于对照组,21 d时差异显著(P<0.05);血糖试验组均高于对照组,21 d时差异显著(P<0.05)。
The purpose of this experiment was probing the effect of multienzyme in the miscellaneous meal diet and preparations on growth,metabolism and the blood indices in weanling piglets.48 weanling piglets was used and divided into 2 groups.1% multienzyme was added in the experimental group on the basic of control group.The experiment was divided into two stages,earlier stage（1 to 21 d） and later stage（22 to 50 d）.The results showed that experimental group was better than control group in the daily gain,the feed to gain ratio（F/G） and the incidence of diarrhea in 1 to 21 d（P0.05）,and in full distance test（1 to 50 d） experimental group was better than control group in the daily gain,F/G and the incidence of diarrhea,but only F/G was different markedly（P0.05）.In 21 d the digestibility of all the nutrients of experimental group were better than those of control group（P0.05） except crude ash.In 50 d the digestibility of crude fat and crude fibre of experimental group were better than those of control group（P0.05）,and the others had no difference.The results of blood biochemical indexes showed that in 21 d and 50 d the experimental group were all better than those of the control group in TP and ALB,but had no obvious difference;the experimental group was lower than that of control group in BUN and only had obvious difference in 21 d（P0.05）;the experimental group was higher than that of control group in GLU and only had obvious difference in 21 d（P0.05）.
