中药复方制剂补中益气散对母猪生产性能的影响

目的试验以中兽医理论为基础,运用中药复方制剂补中益气散对怀孕后期母猪进行产前调理,通过对其生产性能的影响展开研究,旨在为猪饲料中添加使用安全、绿色、有机的中药复方制剂奠定基础。方法将50头预产期相近的母猪,随机分为2组,每组各25头。第1组为对照组,饲喂常规日粮,第2组为试验组,饲料中按1.5%添加中药复方制剂补中益气散,试验组每头母猪添加中药量每天45 g。母猪产仔当天停止给药。母猪生产后,对产仔数、产活仔数、产健仔数、死胎数、弱仔数、木乃伊胎数,以及母猪有无流产等情况进行记录。23 d断奶后对仔猪的腹泻和死亡进行记录。结果①试验组有1头母猪产前出现发烧和食欲不振的情况;对照组有5头出现相同症状;②母猪生产后,对照组产下仔猪227头,死仔12头;试验组产下仔猪254头,死仔9头;③对照组平均窝产活仔数9.08头;试验组平均窝产活仔数10.16头;④对照组发生腹泻的仔猪74头,腹泻率为32.6%;试验组发生腹泻的仔猪10头,腹泻率为3.9%;⑤断奶后对照组窝均健仔数为7.16头;试验组窝均健仔数为9.28头。⑥对照组最后存活179头,存活率为78.9%;试验组最后存活232头,存活率为91.3%。结论①通过运用中药复方制剂补中益气散对母猪进行产前调理,能够有效预防哺乳期仔猪腹泻的发生。②在怀孕期母猪饲料中添加中药复方制剂补中益气散能够提高母猪免疫功能和生产性能。

Effect of Traditional Chinese Medicine Compound Preparation Buzhong Yiqi Powder on Production Performance of Sows

Objective] Based on the theory of traditional Chinese veterinary medicine, a traditional Chinese medicine compound preparation Buzhong Yiqi powder was used to assess its roles in prenatal conditioning for sows in the late pregnancy by investigating its effect on production performance of sows, in hoping to province scientific basis for the application of safe, green and organic feed additives of traditional Chinese medicine compound. Method] A total of 50 sows with similar expected delivery dates were randomly divided into 2 groups with 25 heads of sows in each group. The control group was fed with the basal diet, and the experimental group was fed with the basal diet supplemented with 1.5% （45 g per day per sow） Buzhong Yiqi powder until the date of delivery. After delivery, the number of litters, live litters, healthy litters, stillbirths, weak litters and mummified fetuses were recorded for each group, and the presence of abortion was observed. Incidence of diarrhea and death of the piglets were recorded after weaning at 23 days of age. Results]①In the experimental group, there was one sow had fever and anorexia before delivery, while there were 5 sows showed the same symptoms in the control group; ②After delivery, a total of 227 and 254 piglets were obtained in the control group and the experimental group, respectively, and there were 12 and 9 stillbirths in the control group and the experimental group, respectively; ③ The average size of live litters in the control group and the experimental group was 9.08 and 10.16, respectively; ④ There were 74 and 10 piglets showed the clinical symptoms of diarrhea in the control group and the experimental group, respectively, with the diarrhea rate of 32.6% and 3.9%, respectively; ⑤After weaning, the average size of healthy litters in the control group and the experimental group was 7.16 and 9.28, respectively; ⑥There were 179 and 232 survived piglets in the control group and the experimental group, respectively, with the survival rate of 78.9% and 91.3%, respectively. Conclusion] ①Prenatal conditioning of sows using Buzhong Yiqi powder can effectively prevent the occurrence of diarrhea in suckling piglets.②Dietary supplementation of Buzhong Yiqi powder during pregnancy
