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...

This study was conducted to determine the effects of dietary supplementation with fermented herb residues during perinatal period on reproductive performance of sows and growth performance of their off?spring, to provide the basis for the development and re?utilization of the herb residues. Sixty healthy crossbred sows on close to 85 days of gestation during the 2 to 4 parities were used and randomly allocated to 3 groups with 20 replicates ( one sow each) in this study. The diets were supplemented with 2 kg/t rice bran ( control group) , 2 kg/t herb residues ( from Radix astragali, Radix ange...
