摘　　要：本实验观察了不同时间的低温饲养加浸水应激及浸水应激后不同时间对海兰雏鸡胃肠道粘膜损伤的情况。结果表明：即刻观察雏鸡在低于正常饲养温度5 ℃时加浸水应激后造成胃肠道充血现象并不严重；而浸水应激后不同时间却对雏鸡产生相对较强的影响，特别是冷应激后1～2 h胃肠道充血比较严重，与冷应激前比较差异显著（p<0.05）。所以在生产过程中应避免产生冷应激，否则易诱发其他疾病的发生。This experiment was conducted to observe the injury of digestive tract mucosal induced by cold stress of immersing in cold water in Hailan chickens. The results showed as follows: The hyperaemia of digestive tract just after the treatment of immersing in cold water had no significant impact, but it had a significant influence on chickens during the post cold stress after a period of time, it had a significant hyperaemia after cold stress 1~2 hour especially compared with pre-cold stress. This suggests that we should avoid cold stress in production to prevent other diseases.
