微量元素对蛋鸭生产性能影响的研究进展

Research progress on impact of trace elements on production performance of laying ducks

微量元素是畜禽生长发育必需的营养素,它们是机体多种酶的组成成分或催化剂。微量元素通过调控酶的合成和分泌,调节机体的生命活动,对动物体的生产性能及产品质量具有重要影响。锌和锰在蛋壳的形成过程中起重要作用,可以通过影响蛋壳的超微结构从而影响蛋壳质量。硒具有调节机体抗氧化能力以及抗应激能力的作用。目前,生产中补充的微量元素多为无机形式,但无机形式的微量元素吸收利用率不高,过度添加易造成残留,导致环境污染。有机微量元素具有吸收率高、稳定性强的优势,在饲料中使用有机形式的微量元素替换无机微量元素已经成为趋势。文章综述了微量元素对蛋鸭生产性能的影响,旨在为微量元素在蛋鸭生产中的合理应用提供参考。

Trace elements are essential nutrients for the growth and development of poultry and livestock,serving as components or catalysts for various enzymes in the body.They regulate life activities by controlling the synthesis and secretion of enzymes and have a significant impact on the production performance and product quality of animals.Zinc and manganese play crucial roles in the formation of eggshell,affecting its ultra-microstructure and thereby influencing eggshell quality.Selenium has the function of regulating the antioxidant capacity and stress resistance.Currently,the trace elements supplemented in production are mostly inorganic forms,which have low absorption and utilization rates,and excessive addition can lead to residue and environmental pollution.Organic trace elements have the advantages of high absorption rate and strong stability,and using organic forms of trace elements in feed instead of inorganic forms has become a trend.The article reviews the impact of trace elements on the production performance of laying ducks,aiming to provide a reference for the rational application of trace elements in the production of laying ducks.
