摘要
研究在热应激的情况下,油脂对蛋鸡血液生化指标的影响。选择健康蛋鸡180只,随机分为3组,每组60只,4个重复。一组和二组喂基础日粮,三组喂试验日粮,两种日粮的营养水平相同,但试验日粮中用1.8%的油脂代替了玉米。一组养在人工温控室(22℃),二、三组养在夏季的自然环境中。发现在热应激条件下,油脂能显著地提高血液中总脂、总蛋白、血钾和血钙的浓度(P<0.05),明显降低血糖和醛固酮的浓度(P<0.05),还能一定程度地降低血液皮质醇的浓度。所以,在高温环境中,油脂对维持体内生化指标的正常稳定有明显的作用。
To research the effect of soybean oil on the blood biochemical indexes of laying hen during heat stress, 180 laying hens were randomly divided into 3 groups with 4 repeats, and the groups were separately treated with different breeding conditions and received examinations for their blood biochemical indexes. Results： Under heat stress of summer season, adding soybean oil can significantly increase the levels of serum fat, total protein, K^＋ and Ca^＋ （ P 〈 0.05） and significantly decrease the levels of serum glucose and aldosterone（ P 〈 0.05）. The content of serum cortisol is also decreased. Therefore, soybean oil works evidently to ensure the stable level of blood biochemical indexes for laying hens under heat stress.
