摘　　要：[目的]改善能繁母猪的健康状况,解决或缓解母猪产仔后经常出现便秘、产后食欲不振、产褥热等问题,提升云南省生猪养殖业的经济效益。[方法]在能繁母猪日粮中添加一定比例的紫花苜蓿鲜草,测定母猪采食量、母猪体况、仔猪生产性能、仔猪血清等指标。[结果]紫花苜蓿鲜草可替代能繁母猪日粮中20%~30%的全价饲料,替代后断奶仔猪的个体重及窝重都有不同程度的提高,替代能繁母猪日粮中20%的全价饲料为最佳替代量。饲喂了紫花苜蓿的能繁母猪,其仔猪的健康状况显著提高。[结论]在能繁母猪日粮中添加一定比例的紫花苜蓿鲜草可以提高母猪的繁殖性能、保障仔猪的健康状况、显著减少猪病发生的几率。[Objectives] To improve to the health of the numerous sows,to solve or alleviate the common problems of sows after farrowing,such as constipation,postpartum loss of appetite and puerperal fever,and to improve the economic benefits of pig breeding industry in Yunnan Province.[Methods] The experiment added a certain proportion of alfalfa grass to numerous sows in the diet,Feed intake of sows,body condition of sows,performance of piglets and serum of piglets were measured.[Results] Fresh alfalfa grass could replace 20%-30% of the total feed in the diet of fertile sows,also,the body weight and litter weight of weaned piglets were increased in different degrees after replacement(P<0.05)and the replacement of 20% of the total feed in the diet of fertile sows was the best replacement amount(P<0.05).[Conclusions]Adding a certain proportion of alfalfa grass to the diet of fertile sows could improve the reproductive performance of sows,protect the health status of piglets,and significantly reduce the probability of pig disease.
