摘要
应用生物化学分析方法，试验研究了２６０日龄白来航产蛋鸡在不同光照环境中血液生化指标的变化．结果表明：随着光照时间的增加，血清清蛋白、ＧＰＴ和ＡＫＰ活性以１７小时光照组最高，分别比１４小时光照组高２０．６２％，５９．４１％和２３．０４％，而血清非蛋白氮降低２７．０％。血钙含量以１６小时光照组较高，比１４小时光照组高２６．５７％．提示：不同光照管理对鸡体物质代谢、水盐代谢有一定的影响．本试验为制定合理的光照制度提供了一定的依据。
Study was made on variety of blood biochemical parameters of White leghorn ben of 260 days of age.under different lighting treatments. by biochemical method theresults indicates:1) When the lighting treatment is 17 hours a day, the serumalbumincontent, glutamataw-pyru-rate, transaminase(GPT) and alkaline phosphatase(AKP) activity of hans increase respcttyively by 20. 6%, 59.41 % and 23.04%, while thecontent of blood non-pr-otein nitrogen decrease 27%. as against the treatment of14 hours a day.2) When the lighting treatment is 16 hours a day, the content of blood calcium increase about 26. 57 % as compared with the treatments of 14 hours a day. Above results showed that different lighting treatment could fairly affect metabolism of hens. This study has provide us some useful basis for rational management of lighting treatment.
