【摘要】：本试验旨在通过研究微生物发酵中药渣对围产期母猪繁殖性能和子代发育的影响,为中药渣的二次开发利用提供依据。试验选用2~4胎次、预产期相近的妊娠85 d的健康二元母猪60头,随机分为3组,每组20头。3组分别在基础饲粮中添加2 kg/t米糠(对照组)、2 kg/t中药渣制剂(由黄芪、当归、熟地黄和白芍等组成,中药渣组)和2 kg/t发酵中药渣制剂(发酵中药渣组)。从产前21 d开始饲喂,到产后21 d结束。分别于妊娠110 d、产后21 d时测量母猪背膘厚,记录母猪的产仔数、产活仔数、死胎数、木乃伊数和母猪产后发情间隔;记录仔猪初生窝重,7、14和21日龄窝增重,并计算平均日增重;每天观察仔猪腹泻情况,并计算腹泻率。结果表明:与对照组相比,发酵中药渣组仔猪断奶窝增重显著增加(P0.05),中药渣组和发酵中药渣组仔猪1~14日龄、1~21日龄腹泻率显著增加(P0.05);与中药渣组相比,发酵中药渣组仔猪7日龄窝增重显著增加(P0.05),平均日增重呈升高趋势(P=0.053)。由此可见,围产期母猪饲粮添加中药渣制剂虽然造成哺乳仔猪一定程度的腹泻,但可促进其生长发育,添加发酵中药渣制剂效果更好。
[Abstract]:The purpose of this experiment was to study the effect of microbial fermentation residue on reproductive performance and offspring development of perinatal sows, and to provide the basis for the secondary development and utilization of traditional Chinese medicine residue. A total of 60 healthy white sows with a similar gestational period of 85 days were randomly divided into 3 groups, 20 in each group and supplemented with 2 kg/t rice bran in the basal diet (control group, 2 kg/t) (Astragalus membranaceus, Angelica sinensis), and the control group was divided into two groups: Astragalus membranaceus, Angelica sinensis, Rhizoma angelicae sinensis. The composition of cooked Rehmannia glutinosa and Radix Paeoniae Alba, traditional Chinese medicine residue group, and 2 kg/t fermentative residue preparation. It was fed from 21 days before delivery to the end of 21 days postpartum. The backfat thickness of sows was measured on the 110th day of gestation and 21 days postpartum, and the litter size, live litter size, stillbirth number, mummy number and postpartum estrus interval of sows were recorded. The average daily gain was calculated and the diarrhea rate of piglets was calculated. The results showed that: compared with the control group, the weaning litter weight increased significantly in the fermented Chinese medicine residue group, and the diarrhea rate of the Chinese medicine residue group and the fermenting Chinese medicine residue group significantly increased the diarrhea rate of the piglets at the age of 14 days and 21 days, compared with the traditional Chinese medicine residue group, the diarrhea rate of the Chinese medicine residue group was significantly higher than that of the traditional Chinese medicine residue group. In fermentative residue group, the litter weight gain of 7 days old piglets increased significantly, and the average daily gain of piglets increased with the increasing trend of P0. 053%. It can be seen that the diet of perinatal sows can promote the growth and development of piglets by adding Chinese medicine residue preparation to a certain extent, and the effect of adding Chinese medicine residue preparation in fermentation is better.
