【摘要】:本试验旨在研究抗菌肽替代硫酸粘菌素对断奶仔猪生长性能和抗腹泻性能的影响。试验选用120头断奶日龄为(21±3)d、初始体重为(6.53±0.25)kg的断奶仔猪,随机分为3个处理,每个处理4个重复,每个重复10头猪,即对照组饲喂基础日粮+375 mg/kg金霉素(20%)+250 mg/kg恩拉霉素(8%)、处理Ⅰ组:基础日粮+375 mg/kg金霉素(20%)+250mg/kg恩拉霉素(8%)+100 mg/kg硫酸粘菌素(20%)、处理Ⅱ组:基础日粮+375 mg/kg金霉素(20%)+250 mg/kg恩拉霉素(8%)+400 mg/kg抗菌肽,试验期14 d。结果表明:与对照组相比,处理Ⅰ、Ⅱ组的日采食量分别提高5.15%、4.78%(P0.05),日增重分别提高9.48%、7.11%(P0.05),耗料增重比分别改善4.20%、0.84%(P0.05);与对照组相比,处理Ⅰ、Ⅱ组腹泻率显著降低(P0.05),处理Ⅰ、Ⅱ组间差异不显著(P0.05)。由此可见,在断奶仔猪日粮中不使用硫酸粘菌素后断奶仔猪生长性能和抗腹泻性能有降低趋势,但通过添加400 mg/kg的抗菌肽,可达到与使用硫酸粘菌素类似的效果,说明在断奶仔猪日粮中使用抗菌肽替代硫酸粘菌素是可行的。
