摘要
本试验以基础日粮为对照组，试验组在母猪、仔猪饲料中分别添加150g/t、200g／t微生态制剂，探讨微生态制剂对母猪和仔猪生产性能的影响。试验结果表明，与对照组相比，试验组母猪便秘率显著降低（P〈0．05），试验组母猪每窝平均产仔数多出1．6头（P〈0．05），每窝平均健仔数多出2．1头（P〈0．05），平均仔猪初生重多70克（P〈0．05），断奶仔猪均重比对照组多320克（P〈0．05）；显著减少母猪助产（P〈0．05），显著降低母猪产道炎的发生率（P〈0．05）；增强哺乳仔猪体质，显著降低哺乳仔猪黄痢、腹泻率和哺乳期间死淘率（P〈0．05）。
To study the effects on productive performance of sows and growth performance of suckling piglets by feeding microbial ecological agent 150 g/t,200g/t. The results showed that compared with the control group, Sow Constipation was significantly decreased by adding microbi- al ecological agent compared with that in control group （ P 〈 0.05 ）, piglets in the test group had 70g greater the birth weight （ P 〈 0.05 ）. By the end of 21 day - old, the weaning piglets in the test group had 320g greater litter weight（ P 〈 0.05 ）. The average numbers of litter size and survival farrowing in the test group were significantly 1.6 heads and 2. 1 heads more, respectively com- pared with that in the control group （ P 〈 0.05 ）. Midwifery and tract inflammation was significantly decreased by adding microbial ecological agent compared with that in control group （ P 〈 0.05 ）. The ratio of diarrhea,neonatal colibacillosis of piglets and the mortality of piglets in the test group was significantly decreased by adding microbial ecological agent compared with that in control group （ P 〈 0.05 ）.
