摘要
硒是生命机体必需微量元素之一,成年人日摄入硒的量为50～60 μg.富硒养殖的猪、牛、羊、鸡、鸭、鹅等的肉蛋奶是补硒佳品,硒还能显著提高养殖动物生长性能和抗病力.必须做到科学补硒,若补硒过量易引发硒中毒.富硒农产品标准明确规定肉类和蛋类产品含硒范围为0.15～0.50 mg/kg;富硒养殖涉及的要素有硒制剂、富硒饲料、饲养过程硒的监测、肉蛋奶质量和安全要求,需要制定富硒养殖畜禽产品标准体系.
Abstract
Selenium is one of the essential trace elements for organisms,and the daily intake of selenium in adults is approximately 50μg～60μg.The meat,egg,and milk products sourced from selenium rich farming are good for selenium supplement,in addition,selenium can significantly improve the growth performance and disease resistance in farming animals.However,excessive selenium supplementation can cause poisoning,so it is necessary to supplement selenium reasonably.The range of selenium content in meat and egg products is 0.15 mg/kg～0.50 mg/kg in selenium rich agricultural product standards;the elements involved in selenium rich farming include selenium preparations,selenium enriched feed,monitoring of selenium in the livestock breeding,quality and safety requirements of meat,eggs and milk,so the establishment of a standard system for selenium rich farming products is necessary.
