猪复合预混合饲料中铜、锌含量及合规性分析

Detection and Compliance Analysis of Copper and Zinc Content in Compound Premixed Feed for Pigs

研究旨在分析猪复合预混合饲料中铜、锌微量元素含量的合规性。通过对2018—2021年在广西地区采集的1322批次猪复合预混合饲料,采用GB/T13885—2017《饲料中钙、铜、铁、镁、锰、钾、钠和锌含量的测定原子吸收光谱法》对饲料中的铜、锌元素的含量进行测定。结果表明,部分样品中铜、锌元素含量超出农业部公告第2625号《饲料添加剂安全使用规范》中的最高限量值。猪复合预混合饲料中铜、锌元素含量超过农业部公告第2625号中的最高限量的情况应高度重视。

This study aims to analyze the compli⁃ance of copper and zinc trace elements in com⁃pound premixed feed for pigs.Through 1322 batches of compound premixed feed for pigs collected in Guangxi from 2018 to 2021,GB/T 13885-2017"Determination of the contents of calcium,copper,iron,magnesium,manganese,potassium,sodium and zinc in feeds-Method using atomic absorption spectrom⁃etry"to determine the content of copper and zinc in feed.The results showed that the content of copper and zinc in some samples exceeded the maximum limit value in the Ministry of Agriculture Announce⁃ment No.2625"Code for Safe Use of Feed Additives".More attention should be paid to the fact that the content of copper and zinc in compound premixed feed for pigs exceeds the maximum limit in the Minis⁃try of Agriculture Announcement No.2625.
