不同复合微生态制剂对断奶仔猪生产性能的影响

Effects of Different Micro Ecological Agents on Performance of Weaned Piglets

为比较3种复合微生态制剂对断奶仔猪生产性能的影响,试验选用160头23日龄体重接近且健康的杜×长×大断奶仔猪,按照公母各半原则分为A、B、C、D 4个处理组,每组4个重复,每个重复10头。其中A组为对照组,饲喂基础日粮,B组为基础日粮+复合微生态制剂a,C组为基础日粮+复合微生态制剂b,D组为基础日粮+复合微生态制剂c,分别测定4组断奶仔猪的平均日增重、平均日采食量、仔猪腹泻率、仔猪成活率、精神状况、毛色、粪便中挥发性脂肪酸(VFA)等指标。试验期为30 d。结果表明:3个试验组断奶仔猪生产性能优于对照组,其中饲粮中添加复合微生态制剂c的D组,仔猪的平均日增重较对照组提高了27.68%(P<0.05),耗料增重比降低了14.13%(P<0.05),仔猪腹泻率降低了75%,仔猪成活率提高了11.43%。因此,断奶仔猪饲粮中添加复合微生态制剂可以有效提高日增重,降低耗料增重比,降低病死率;且与复合微生态制剂a、b比,复合微生态制剂c(根源益倍佳)的作用效果更佳。

The aim of this study was to compare the effects of three composite probiotics on the performance of weaned piglets. In the experiment, 160 piglets of 23 days old and similar weight and healthy ＂ Duroc×Large white×Landrace ＂ were selected. They were divided into four treatment groups, A, B, C and D according to the principle of half and half of the male and female. Each group had 4 repetitions, each with 10 repeats. Group A was the control fed with basal dict. group B were led with basal diet ＋ probiotics a, group C were fed with basal diet ＋ probiotics B, group D were fed with basal diet ＋ probiotics c： test continued 30 days. The results showed that the growth performance of weaning piglets of the 3 test group were better than the control group, the effect group D is particularly prominent, the average daily gain of piglets in group D were higher than those of the control group 27.68% （P〈0.05）, feed to gain ratio decreased by 14.13%, （P〈0.05）, diarrhea rate 75%. the survival rate of piglets increased 11.43%. Therefore, the diet of weaned piglets in composite probiotics could effectively improved the daily gain, lower feed to gain ratio, reduced the mortality rate; and compared with compound microecoligical agents a and b, c（Yibeijia of GBW） was best.
