摘　　要：在每吨母猪基础日粮中添加Vc、Ve、MgSO4、Na2SO4各100 g,吡啶羧酸铬0.2 g。结果表明,该营养调控剂对瘦肉型母猪饲料DMI无显著影响;试验组的窝产总活仔数、仔猪平均窝增重、断奶窝重分别比对照组显著提高12.96%、32.27%、25.67%,说明该营养调控剂在一定程度上能改善瘦肉型母猪的繁殖性能,提高仔猪的生长性能及成活率。A nutritional regulation agent explored to supply in the basal diet of the lean breeding sows was constituted with Vc, Ve, MgSO4, Na2S04 100 g/t respectively and chromium picolinate 0.2 g/t. Experimental results showed that the nutritional regulation agent had no significant impact on lean sow＇s feed DMI, the live litter size at birth, the average litter weight gain of piglets, the weaning weight of the test group increased 12.96%, 32.27%, 25.67% significantly compared with the control group. The nutritional regulation agent in a certain extent could improve lean breeding sows＇ reproductive performances, piglets＇ growth performances and the survival rate.
