摘要
蛋白质饲料资源短缺和高氮排放污染问题是制约养殖业发展的重要因素,因此,低蛋白质饲粮技术作为解决这些问题的措施已被广泛应用.矿物元素也称矿物质或无机盐,其参与机体代谢,是构成动物机体组织和维持正常生理功能所必需的元素,在体内发挥着结构支撑、代谢维持、催化调节等关键作用.饲粮蛋白质与矿物元素消化代谢之间存在一些联系,这些联系可能会影响动物对矿物元素的需求和利用.因此,本文旨在对不同饲粮蛋白质条件下对钙、磷、镁、铁、锌、铜、锰、硒等8种矿物元素消化代谢的影响进行综述,以期为养殖业中低蛋白质饲粮的应用提供参考.
Abstract
The shortage of protein feed resources and high nitrogen emission pollution are important factors re-stricting the development of animal industry.Therefore,low-protein diet technology has been widely used as a measure to solve these problems.Mineral elements,also known as minerals or inorganic salts,participate in body metabolism and are essential elements for constituting animal body tissues and maintaining normal physio-logical functions,playing a key role in the body such as structural support,metabolic maintenance,and cata-lytic regulation.There are some relationships between dietary protein and mineral element digestion and metab-olism,which may affect the mineral element demand and utilization of animals.Therefore,the purpose of this paper is to review the effects of different dietary protein conditions on the digestion and metabolism of eight mineral elements,such as calcium,phosphorus,magnesium,iron,zinc,copper,manganese and selenium,in order to provide reference for the application of low-protein diets in animal industry.[Chinese Journal of Ani-mal Nutrition,2024,36(9):5510-5522]
