摘要
为研究博落回散对断奶仔猪生长性能的影响,试验选用21日龄、体重相近的杜×长×大断奶仔猪92头,随机分为2个处理组。对照组饲喂基础日粮,试验组饲喂基础日粮＋50 mg/kg博落回散,试验期为32 d。结果表明,试验组仔猪较对照组平均日采食量提高3.96%（P〈0.05）,平均日增重提高9.08%（P〈0.05）,料肉比降低4.67%。由此可见,博落回散按50 mg/kg剂量添加到仔猪饲料中能提高断奶仔猪的生长速度,有效缓解断奶应激。
This study was conducted to investigate the effects of Macleaya cordata powder on growth performance of weaned piglets.Ninety two DurocxlandracexYorkshire piglets weaned at 21 d and were randomly allotted to 2 treatments, control group （basal diet without antibiotics） and experiment group （basal diet ＋50 mg/kg Macleaya cordata powder）.The experiment lasted for 32 d.The results showed that, the average daily feed intake （ADFI）,average daily gain （ADG） of Macleaya cordata powder group were significantly increased by 3.96% （P 〈 0.05）,9.08% （P 〈 0.05） and feed conversion rate （FCR） were significantly decreased by 4.67%.In conclusion,adding 50 mg/kg Macleaya cordata powder in basal diet could improve growth performance and alleviate stress in weanling piglets.
