复合微生态制剂对樱桃谷肉种鸭生产性能的影响

Effects of Compound Microbial Ecological Agent on Productive Performance in Cherry Valley Parent Stock

选取51周龄樱桃谷肉种鸭8栋，每栋鸭舍3000只，随机平均分为对照组和试验组，每组各4栋。对照组饲喂基础日粮，试验组在对照组的基础上添加200g／t复合微生态制剂，试验30天后观察复合微生态制剂对肉种鸭生产性能的影响。结果表明，试验组显著提高樱桃谷肉种鸭产蛋率2．20％（P〈0．05）、显著提高种蛋合格率1．89％（P〈0．05），显著降低死淘率18．54％（P〈0．05）。试验结果证明，复合微生态制剂能够显著提高樱桃谷肉种鸭的生产性能，并且需要长期连续添加。

5000 Cherry Valley ducks at 51 -week -old were randomly divided into two groups,each group had 4 replicates, and there were 3000 Cherry Valley ducks in every replicate group. The experiments were continued for 30 days. To study the effects on production performance of laying hens by feeding compound microbial ecological agent 200g/t. The results showed the compound microbial ecological agent significantly increased average laying rate by 2.20% （ P 〈 0.05 ） , significantly increased qualifitied rate of hatching eggs by 1.89% （ P 〈 0.05 ） and signifi- cantly decreased mortality by 18.54% （P 〈0.05） compared with that in control group during the growing period. It showed that compound microbial ecological agent added in the diets of Cherry Valley Parent Stock could improve the production performance, and it should be added continuous- ly for a long term.
