【摘要】：本試驗(yàn)旨在研究抗菌肽替代硫酸粘菌素對(duì)斷奶仔豬生長(zhǎng)性能和抗腹瀉性能的影響。試驗(yàn)選用120頭斷奶日齡為(21±3)d、初始體重為(6.53±0.25)kg的斷奶仔豬,隨機(jī)分為3個(gè)處理,每個(gè)處理4個(gè)重復(fù),每個(gè)重復(fù)10頭豬,即對(duì)照組飼喂基礎(chǔ)日糧+375 mg/kg金霉素(20%)+250 mg/kg恩拉霉素(8%)、處理Ⅰ組:基礎(chǔ)日糧+375 mg/kg金霉素(20%)+250mg/kg恩拉霉素(8%)+100 mg/kg硫酸粘菌素(20%)、處理Ⅱ組:基礎(chǔ)日糧+375 mg/kg金霉素(20%)+250 mg/kg恩拉霉素(8%)+400 mg/kg抗菌肽,試驗(yàn)期14 d。結(jié)果表明:與對(duì)照組相比,處理Ⅰ、Ⅱ組的日采食量分別提高5.15%、4.78%(P0.05),日增重分別提高9.48%、7.11%(P0.05),耗料增重比分別改善4.20%、0.84%(P0.05);與對(duì)照組相比,處理Ⅰ、Ⅱ組腹瀉率顯著降低(P0.05),處理Ⅰ、Ⅱ組間差異不顯著(P0.05)。由此可見(jiàn),在斷奶仔豬日糧中不使用硫酸粘菌素后斷奶仔豬生長(zhǎng)性能和抗腹瀉性能有降低趨勢(shì),但通過(guò)添加400 mg/kg的抗菌肽,可達(dá)到與使用硫酸粘菌素類(lèi)似的效果,說(shuō)明在斷奶仔豬日糧中使用抗菌肽替代硫酸粘菌素是可行的。
[Abstract]:The aim of this experiment was to study the effect of antibacterial peptide instead of colistin sulfate on growth performance and anti-diarrhea performance of weanling piglets. One hundred and twenty weaned piglets of (21 鹵3) days old and (6.53 鹵0.25) kg initial weight were randomly divided into three treatments, each with 4 replicas and 10 pigs per repeat. The control group was fed a basic diet of 375 mg/kg chlortetracycline (20%) 250 mg/kg enramycin (8%). Group 鈪，
