摘要

目的

分析云南省曲靖市范围内畜禽添加剂预混合饲料中铜、锌微量元素含量，判断其添加使用是否符合国标规定。

方法

2020－2024年抽检添加剂预混合饲料样品56批次样品，包括仔猪（含断奶仔猪）、母猪、生长育肥猪、禽类专用、牛（羊）专用等不同种类，参照GB/T 13885－2017《饲料中钙、铜、铁、镁、锰、钾、钠和锌含量的测定原子吸收光谱法》对采集样品的铜、锌含量进行测定，检测结果按GB/T 18823－2010《饲料检测结果判定的允许误差》根据标签标示值进行结果判定，统计不合格率。

结果

生长育肥猪各1批次铜、锌元素含量不合格，不合格率4.3%；禽类各1批次铜、锌元素含量不合格，不合格率14.3%。

结论

在添加剂预混合饲料中超量添加铜、锌元素的情况依然存在，后续要加大抽检力度，对饲料生产企业和养殖户合规添加铜、锌元素进行有效监管。

Abstract

Objectives

The content of trace elements including copper and zinc in the additives of premixed feed for livestock and poultry livestock in Qujing City

Yunnan Province was analyzed to judge whether their addition and use comply with national standards.

Methods

56 batches of additives of premixed feed for livestock and poultry including piglets and weaned piglets

sows

growing-fattening pigs

poultry

cattle (sheep) and other different types in Qujing City were randomly sampled from 2020 to 2024. The content of copper and zinc in the samples collected was determined with reference to GB/T 13885－2017 "

Determination of the content of Calcium

Copper

Iron

Magnesium

Manganese

Potassium

Sodium

and Zinc in Feed-Atomic Absorption Spectroscopy

Method

". The results of determination were judged based on the labelled values in accordance with GB/T 18823－2010 "

Allowable Error for Determination of Feed Test

Results

The content of copper and zinc in 1 batch of growing-fattening pigs was unqualified

with a failure rate of 4.3%. 1 batch of poultry contained unqualified content of copper and zinc

with a failure rate of 14.3%.

Conclusions

The situation of excessive addition of copper and zinc in the additives of premixed feed for livestock and poultry in Qujing City

Yunnan Province still exists. In the future

it is necessary to increase efforts of sampling and effectively supervise the compliance of enterprises and farmers in adding the copper and zinc to the additives of premixed feed for livestock and poultry.
