摘　　要：[目的]探究日粮中添加酸化剂和植物精油组合对仔猪生长性能的影响,为替抗产品在仔猪健康养殖中的应用提供参考。[方法]选取420头法系二元断奶仔猪,按体重随机分为3个组,每个组4个重复,每个重复35头。仔猪分别饲喂基础日粮(对照组),基础日粮+3 kg/t酸化剂+0.4 kg/t植物精油(替抗组),基础日粮+0.5 kg/t硫酸新霉素(抗生素组),试验周期共42 d,分别于14 d和42 d称重换料。[结果]与对照组相比,替抗组2个试验阶段(断奶仔猪和保育仔猪)猪群的日均采食量分别提升了4.2%和4.9%,平均日增重分别提升了8.5%和7.4%,料肉比(FCR)分别降低4.1%和2.0%,并显著改善了仔猪的粪便形状及毛色(P<0.05),效果优于抗生素组。[结论]在仔猪日粮中添加酸化剂和植物精油组合可以明显提升仔猪的生长性能,并降低仔猪腹泻比例以及改善毛色。[Objectives]The effects of adding a combination of acidifier and plant essential oil on the growth performance of piglets were studied to provide reference for its application of antibiotic alternatives in the healthy farming of piglets.[Methods]A total of 420 French binary weaned piglets were randomly divided into 3 groups based on body weight,with 4 replicates in each group and 35 piglets in each replicate.The piglets were fed with basal diet(control group),basal diet+3 kg/t acidifier+0.4 kg/t plant essential oil(alternative for antibiotic group),basal diet+0.5 kg/t neomycin sulfate(antibiotic group).The experimental period was 42 d and the refueling was weighed at the end of 14 d and 42 d.[Results]The ADFI and ADG of the piglets in the two experimental stages(breeding and nursery piglets)of the alternative for antibiotic group increased by 4.2%and 4.9%,8.5%and 7.4%,respectively,and the FCR decreased by 4.1%and 2.0%compared with that of the control group.The fecal shape and coat color of piglets were significantly improved(P<0.05),and the effect was better than that of the antibiotic group.[Conclusions]It is indicated that adding a combination of acidifiers and plant essential oils to piglet diets can significantly improve the growth performance of piglets,reduce piglet diarrhea and improve the coat color of piglets.
