【摘要】：本试验旨在探讨不同时期蛋鸡回肠内锌(Zn)、铁(Fe)、镁(Mg)、钙(Ca)、锰(Mn)、磷(P)和钾(K)的变化特点。试验选取不同时期蛋鸡(青春期-15周龄、产蛋高峰期-30周龄和高峰后期-45周龄)的回肠组织,借助ICP检测其中Zn、Fe、Mg、Ca、Mn、P和K的含量,利用软件SPSS22进行多重比较和相关性分析。结果表明:15周龄和30周龄蛋鸡回肠内K元素极显著高于45周龄(P0.01);30周龄时P、Zn和Mn的含量最高,显著高于其他2个时期(P0.05);45周龄时,Mg和Fe的含量最高,显著高于15周龄和30周龄(P0.05);相关性分析发现,蛋鸡回肠中Mn、P、Zn之间均呈正相关(P0.05),P与K呈正相关(P0.05),且二者均与Mg呈负相关(P0.05),此外K与Fe元素也呈负相关(P0.05),Mg与Fe呈正相关(P0.05)。因此,不同时期蛋鸡回肠各种元素的量不同,可据此调整饲粮中必需元素的添加量。
[Abstract]:The purpose of this study was to investigate the change characteristics of Zn ~ (2 +), Fe ~ (2 +), mg ~ (2 +), Ca ~ (2 +), Ca ~ (2 +), mn ~ (2 +), P _ ((P)) and K _ (K) in ileum of laying hens at different stages. The ileum tissues of laying hens in different periods (puberty to 15 weeks old, peak egg laying period to 30 weeks old and peak period to 45 weeks old) were selected, and the contents of ICP were detected by ICP, and the multiple comparisons and correlation analysis were carried out by software SPSS22. The results showed that the contents of K in ileum of 15 and 30 week old layers were significantly higher than those of 45 weeks old and 45 weeks old. The contents of Zn and mn in the ileum of 15 and 30 week old layers were the highest, and the contents of mg and Fe were the highest at 45 weeks of age. The correlation analysis showed that there was a positive correlation between P0.05mg and K in the ileum of laying hens, and there was a negative correlation between P0.05P and K, and a negative correlation between P0.05mg and Fe, and a positive correlation between P0.05mg and Fe in the ileum of laying hens. Therefore, the amount of various elements in the ileum of laying hens varied in different periods, and the amount of essential elements in diet could be adjusted accordingly.
