为探讨表皮生长因子E（GF）对早期断奶仔猪生产性能、血清理化指标及免疫功能的影响,选取21日龄断奶仔猪25头,初重（5.83±0.60）kg,公母比例3:2,随机等分为5组,分别注射不同水平EGF,对照组为生理盐水,试验期14天。结果表明:仔猪生产性能、血清理化指标及IgG含量与每天所用剂量在1.0～9.0μgk/gB W范围之内随剂量增加日趋改善,最佳水平为每天6.0μg k/gB W。与对照组相比,日增重提高65.42%P（

A feeding trial involving 25 21-day-old weaned pigs,randomly distributed into five treatment groups,was conducted to evaluate the effect of different levels of epidermal growth factor（EGF）on production performance,serum biochemical parameters and immune function.The pigs in five treatments were injected subcutaneousty with four levels of epidermal growth factor （1.0,3.0,6.0,9.0μg/kgBW.day）and 0.9% NaCl（the control） respectively.The result showed that there was a significant dose-related effect in production performance,serum parameters a...
