摘要
为探讨中草药添加剂对泌乳母猪生产性能的影响，本研究选取40头3～5胎次的健康状况良好、妊娠80～90d的大白母猪，按照配种日龄、胎次、体况，随机分为中草药组和对照组，每组20头母猪。两组基础日粮相同，中草药组在基础日粮基础上添加1％的中草药添加剂。结果表明：（1）与对照组相比，中草药组母猪在哺乳期头均总采食量和头目均采食量分别提高了19．5kg和0．8kg，分别提高了12．31％和12．10％，差异显著；窝均总产仔数、窝均产活仔数、窝均产健壮仔数分别提高了O．18头、0．44头和0．48头；产活仔率、产健壮仔率分别提高了2．22％和2．59％；弱仔率、死胎率及木乃伊率则均有所降低；断奶窝均重、断奶头均重、窝增重、仔猪日均增重分别提高了10．65kg、0．52kg、10．10kg、25．99g，分别提高了14．64％、7．11％、17．91％、11．44％；死淘率方面，降低2．11％。（2）与对照组相比，中草药组产程有所缩短，但差异不显著；产后恶露持续时间缩短1．3天，差异显著；乳房炎发生率明显降低；断奶后4～7天发情率达到90％，提高了15％。
In order to study the effects of Chinese Herbal additives on production performance of nursing sows, according to breeding age, parity, body condition, 40 good health Yorkshire sows with pregnant 80 - 90 d and 3 ~ 5 parity were randomly divided into treatment group （ diet ＋ 0.1% Chinese Herbal additives） and control group （ only with diet） with 20 sows per group. The results showed as follows ： 1 ） Compared with the control group, in the feed intake and the average daily feed intake the treatment group significantly increased by 19.5kg and 0.8 kg, which were increased by 12.31% and 12.10 %, respectively during lactation. And the litter size, the num- ber of live births, the number of robust piglets were increased by 0.18, 0.44 and 0.48 respec- tively. The rate of born alive, rate of born robust were increased by 2.22% and 2.59%, respectively. The rate of weak piglets, still birth rate and the rate of parturition were decreased, Wea- ning average weight, average weight at weaning, litter weight gain, average daily weight gain were increased by 10.65 kg, 0.52 kg, 10.10 kg, and 25.99 kg, which were increased by 14.64% , 7.11% , 17.91%, 11.44% respectively,and death and culling rate were decreased by 2.11% 2） Compared with the control group, the treatment group of labor has been shortened, but had no significant difference. The lochia has been shorten 1.3 days, and the difference was significant. The rate of mastitis were decreased significantly. 4 -7 days after weaning estrus rate were 90% and increased by 15%
