摘　　要：本试验旨在研究母猪饲粮添加玉米干酒糟及其可溶物(DDGS)对母猪繁殖性能的影响。选用"长×大"二元杂交初产母猪128头,配种后根据体况随机分到对照组(无DDGS添加,n=65)和处理组(添加DDGS组,n=63)。通过连续测定母猪4个繁殖周期的生产成绩,观察长期饲喂添加玉米DDGS饲粮对母猪繁殖性能的影响。结果表明:饲粮添加玉米DDGS组母猪哺乳期损失体重低于对照组母猪(P<0.05)。与对照组母猪相比,添加玉米DDGS组母猪的窝产仔数、窝产活仔数、断奶窝重和哺乳期窝增重显著降低(P<0.05)。综上所述,长期饲喂添加玉米DDGS的玉米豆粕型饲粮导致母猪繁殖性能降低。The objective of the current study was to investigate the effects of dietary corn distillers dried grains with solubles （DDGS） supplementation on reproductive performance of sows. One hundred and twenty-eight crossbred （LandracexYorkshire） gilts were randomly allocated to the control group （without DDGS supplementation, n=65） or the treatment group （with DDGS supplementation, n=63）. In order to study the effect of long term dietary corn DDGS addition, we determined the productive performance of sows for four reproductive cycles. Our results showed that sows fed diets supplemented with corn DDGS had a lower body weight loss during lactation than the control diets （P〈0.05）. Compared with the control diets, total number of piglets born per litter, total number of piglets born alive per litter, litter weight at weaning, and litter weight gain during lactation were reduced in sows fed corn DDGS-supplemented diets （P〈0.05）. In summary, long term feeding of corn-soybean meal basal diets supplemented with DDGS impaired reproductive performance of sows.
