摘要
试验旨在探讨凝结芽孢杆菌替代日粮中抗生素对断奶仔猪生长性能、血清生化指标和粪便菌群的影响。试验选取32 d断奶的D×L×Y仔猪90头,分成3个处理,5个重复。对照组饲喂抗生素饲粮(含喹乙醇100 mg/kg、50%吉他霉素100 mg/kg和10%硫酸粘杆菌素200 mg/kg),I组饲喂试验饲粮(含凝结芽孢杆菌800 mg/kg、50%吉他霉素50 mg/kg和10%硫酸粘杆菌素100 mg/kg),II组饲喂试验饲粮(含凝结芽孢杆菌1 500 mg/kg和10%硫酸粘杆菌素100 mg/kg),为期35 d。结果表明:试验组仔猪日增重、采食量及饲料增重比均与对照组差异不显著(P>0.05);试验II组仔猪腹泻率高于其他组,但差异不显著(P>0.05),其血清总蛋白(TP)含量显著高于抗生素组(P<0.05),但与试验I组差异不显著(P>0.05);各组粪便菌群无显著差异(P>0.05)。综合认为,凝结芽孢杆菌800 mg/kg替代断奶仔猪饲粮中喹乙醇100 mg/kg、50%吉他霉素50 mg/kg和10%硫酸粘杆菌素100 mg/kg较为适宜于目前生产。
This study was designed to investigate the Bacillus coagulans replacing dietary antibiotics on growth performance, serum biochemical parameters and fecal bacterial flora of weaned piglets. Ninety 32-day-old Duroc ×Landranee × Yolkshire weaned piglets were divided into three treatments with 5 replicates and 6 piglets in each replicate. Control group was fed antibiotic diet （containing Olaquindox 150 mg/kg sulfate 200 mg/kg）, group I was fed Bacillus coagulans diet Kitasamycin 50 mg/kg and 10% Colistin sulfate 100 mg/kg Bacillus coagulans daily weight gain, with control group , 50% Kitasamycin 100 mg/kg and 10% Colistin （containing Bacillus coagulans 800 mg/kg, 50% ）, group II was fed Bacillus coagulans diet（containing 1 500 mg/kg and 10% Colistin sulfate 100 mg/kg ）, lasted for 35 days. The results showed that the daily feed intake and feed/gain of group I and group II were no significant differences compared （P〉0.05）, diarrhea rate of group II were seriously than control group and group I but the difference was not significant（P〉0.05）. The level of TP of group II was that using 800 mg/kg Bacillus coagulans instead of 150 Colistin sulfate was more suitable for the actual produ higher than that of control group（P〈0.05）. It was concluded mg/kg olaquindox, 50 mg/kg 50% Kitasamycin and 10% 100 mg/kg ction in currently.
