摘　　要：选择72头初始重15kg的三江白猪分为三组，每组24头。试验分15～30kg、30～60kg两个阶段。对照组不喂抗生素，试1组日粮中添加5×10－4含量为10％的盐霉素，试2组添加5×10－4含量为15％的金霉素。结果表明，15～30kg阶段日增重试1组、试2组分别比对照组提高3．12％（P＞0．05）和6．52％（P＜0．05），两试验组间没有显著差异；料肉比分别提高5．61％和7．94％，各组间无显著差异（P＞0．05）。30～60kg阶段三组日增重试1组、试2组分别比对照组提高8．2％（P＜0．05）和5．41％（P＞0．05，两试验组间没有显著差异；料肉比分别提高7．05％和4．59％，各组间无显著差异（P＞0．05）。在15～30kg阶段日粮中添加金霉素、30～60kg阶段添加盐霉素比较适宜。San－jiang White pigs with initial weigh 15kg BW were selected and randomly assigned to three treatment groups． Treatment 1 received diet that contained 500×10－6 10％Salinomycin treatment 2 received 500×10－6 5％Aureomycin the control received diet had no any antibiotic． Compared with the control from 15kg BW to 30kg BW daily gain of treatment 1 and treatment 2 increased 3．12％（P＞0．05） and 6．52％P＜0．05 respectively between two treatments there had no significant difference feed efficiency increased 5．61％ and 7．94％ respectively different treatments had no significant difference from 30kgBW to 60kgBW daily gain of treatment 1 and treatment 2 increased 8．2％P＜0．05 and 5．41％P＞0．05 respectively between two treatments there had no significant difference feed efficiency increased 7．05％ and 4．59％ respectively different treatments had no significant difference
