家禽微量元素敏感指标研究进展

Research Progress of Trace Element Sensitive Indexes for Poultry

微量元素作为鸡饲粮中必须添加的一类矿物质元素,与鸡只生长发育及维持其正常生理机能息息相关。关于微量元素的添加量及添加效果,国内外学者已进行了大量研究。本文综述了相关试验研究,对家禽铜、铁、锰、锌的需要量和生物学利用率相关评价指标进行综合比较,以期提供一些全面系统地衡量、监测微量元素状况的生理生化指标。

Trace elements are necessary in chicken diet,which are related to the growth and maintenance of normal physiological functions of chickens.Researchers have conducted a lot of researches on the additive a⁃mount and effect of adding trace elements.A comprehensive comparison of the evaluation indicators related to poultry copper,iron,manganese,zinc requirements and bioavailability,in order to provide some comprehen⁃sive and systematic physiological and biochemical indicators for measuring and monitoring the status of trace el⁃ements.
