绵羊精液睾酮和微量元素变化与精液品质的关系

Seasonal Changes of Seminal Testosterone and Minerals and the Relationship between Testosterone, Minerals and Seminal Quality in Ram

公绵羊精液睾酮（Ｔ）水平在８～１２月极显著高于１～７月（Ｐ＜００１）。精液锌含量在配种季节１０～１２月明显高于非配种季节６月（Ｐ＜００１）；铜含量在配种季节９月明显高于５～８月（Ｐ＜００１）；硒含量在配种季节８～９月明显高于非配种季节４～６月（Ｐ＜００１）；铁、锰含量在非配种季节４～６月较高。精液中硒含量变化与配种季节开始Ｔ水平的升高和精液品质的改善变化趋势一致。

The level of seminal testosterone was significantly higher in Aug～Dec than that in Jan～July (P<001) in ram The concentration of seminal zinc in Oct～ Dec was higher than that in June(P<001) The concentration of seminal copper in Sep was higher than that in May～Aug Seminal selenium level was higher in Aug and Sep than that in Apr～June The peak levels of seminal iron and manganese were found in Apr～June The results suggested that concentration of seminal selenium was highly in agreement with changes of seminal testosterone level and seminal quality
