　　本研究旨在评估复合抗菌肽对断奶仔猪生长性能和健康状况的影响.试验期共28天,36头断奶仔猪(平均体重10.58±-0.99 kg)随机分为3个处理,对照组饲喂基础饲粮；抗生素组在基础饲粮中添加硫酸粘杆菌素20mg/kg和吉他霉素50mg/kg；复合抗菌肽组在基础饲粮中添加400mg/kg抗菌肽.结果表明：复合抗菌肽组相比于对照组和抗生素组显著提高了8-14天和15-21天的仔猪平均日增重(P＜0.05)；复合抗菌肽组较对照组显著提高了全期的饲料转化率(P＜0.05)；复合抗菌肽组和抗生素组较对照组显著降低了1-7天的仔猪腹泻率(P＜0.05)；复合抗菌肽组较对照组显著增加双歧杆菌和乳酸杆菌的数量(P＜0.05),减少大肠杆菌数量(P＜0.05),显著提高了干物质的表观消化率(P＜0.05).以上研究结果表明,饲喂复合抗菌肽可以改善断奶仔猪的生长性能和健康状况.
