摘要
通过饲养对比试验,研究向日粮中添加不同剂量的微量元素硒对肉仔鸡成活率和生长性能的影响。研究结果表明,肉仔鸡在采食不同硒水平日粮（0.025-0.200 mg/kg）时,对生长性能、饲料转化率和成活率均呈现不同程度的提高作用,尤以日粮中硒的添加量为0.125 mg/kg时,能显著提高生长性能和成活率。
The objective of this study was to investigate the effects of different doses of Se on survival rate and growth performance of broilers.The results showed that different doses of Se（0.025～0.200 mg/kg） can improve feed conversion rate and survival rate in various degrees,especially 0.125 mg/kg of dietary Se can improve growth performance and survival rate significantly.
