复合酶制剂和芽孢杆菌类微生态制剂对断奶仔猪生长性能、腹泻率及经济效益的影响

Effects of Multienzyme Complex and Bacillus Probiotics on the Growth Performance,Diarrhea Rate and Economic Benefits in the Early-weaned Piglets

为研究在日粮中添加复合酶制剂和芽孢杆菌类微生态制剂对断奶仔猪生长性能、腹泻率和经济效益的影响,试验将120只23日龄断奶仔猪随机分为4组,每组3个重复,每个重复10头,公母对半。其中,对照组饲喂基础日粮,试验A、B、C组分别在常规饲料的基础上添加0.25%复合酶制剂、0.25%芽孢杆菌类微生态制剂、0.25%复合酶制剂+0.25%芽孢杆菌类微生态制剂,试验周期为28 d。结果显示,3个试验组仔猪的末重、平均日增重均显著高于对照组(P<0.05);3个试验组仔猪的料重比均显著低于对照组(P<0.05);3个试验组的腹泻率均极显著低于对照组(P<0.01),试验C组的腹泻率均极显著低于试验A组和试验B组(P<0.01);与对照组相比,试验A、B、C组仔猪增重毛利润比对照组分别增加了20.99、26.64、29.77元。在饲料中同时添加复合酶制剂和芽孢杆菌类微生态制剂可以起到较好的作用。

The experiment was conducted to investigate the effect of adding multienzyme complex and bacillus probiotics on the growth performance,diarrhea rate and economic benefits of the Early-weaned Piglets.A total of 120 weaned 23-day-old weaned piglets were randomly divided into 4 groups in the experiment,with 3 replicates in each group,with 10 piglets in each replicate,male and female in half.The control group was fed with basic diet,while experimental groups A,B,and C were supplemented with 0.25%multienzyme complex,0.25%bacillus probiotics,0.25%multienzyme complex+0.25%bacillus probiotics.The experimental period was 28 days.The results showed that the final weight and the ADG of piglets in the three experimental groups were significantly higher than that in the control group(P<0.05).The feed to weight ratio of piglets in the three experimental groups was significantly lower than that in the control group(P<0.05).The diarrhea rates of the three experimental groups were extremely significantly lower than the control group(P<0.01).The diarrhea rate in experiment C group was extremely significantly lower than that in experiment A and experiment B groups(P<0.01).Compared with the control group,the breeding profit of piglets in experimental groups were 20.99,26.64 and 29.77 yuan/head higher respectively.The addition of both multienzyme complex and bacillus probiotics in feed can have a good effect.
