锰在鸡肠道中吸收的特点、影响因素及分子机制

Characteristics,Affecting Factors and Molecular Mechanisms of Manganese Absorption in Chicken Intestine

锰是动物必需的微量元素之一,但鸡等家禽对锰的吸收率极低,为1%～3%。本文综述了锰在鸡肠道中的吸收特点、影响锰吸收的因素及其分子机制,旨在为寻找有效提高家禽锰吸收利用的途径提供参考依据。

Manganese （Mn） is one of the essential trace elements required by animals and birds, but the ab sorption and utilization of manganese in chickens and other poultry are very low （ 1% to 3 % ）. This review summarized the absorption characteristics and types of manganese in the chicken intestine and possible molecu lar mechanisms. Furthermore, factors that affect the absorption of manganese were also discussed, which would provide theoretical basis for further researchs on the promotion of manganese absorption in chicken and other animals.
