不同厂家实验动物饲料质量调查分析

Investigation and Analysis of Experimental Animal Feeds Quality of Different Manufacturers

目的了解当前我国实验动物饲料质量现状,为标准化实验动物饲料生产提供依据。方法选择市场占有率高、代表性强的五家不同来源饲料厂家生产的实验动物饲料,采用国标法对成品料常规营养成分进行测定比较分析。结果不同厂家生产的鼠繁殖料、猴维持料、犬料、兔料、豚鼠料常规养分含量存在显著差异,饲料水分、粗蛋白、钙及磷含量均符合国标,个别厂家生产的鼠繁殖料、猴维持料、兔料存在灰分、粗纤维含量超标、粗脂肪含量偏低的情况。此外,五种饲料中微量元素含量不合格检出率高,主要为铁和碘含量的超标。结论不同实验动物饲料生产厂家常规养分质量基本能达到国标要求,但缺乏对微量元素等指标的监测,导致产品不合格率高。因此,还需要加强和提升饲料标准化体系建设和质控监督等关键环节,确保实验动物饲料标准化和规范化。

Objective To understand the current situation of laboratory animal feed quality in China and provide the basis for standardizing laboratory animal feed production.Method Five feed companies with high market share and strong representativeness were selected to produce laboratory animal feeds,and the conventional nutritional components of the feeds were determined and compared by the national standard method.Result There were significant differences in the routine nutrient contents of rat breeding material,monkey maintenance material,dog material,rabbit material and guinea pig material produced by different companies,and the contents of feed moisture,crude protein,calcium and phosphorus met the national standards.The rat breeding material,monkey maintenance material and rabbit material produced by individual companies had ash,excessive crude fiber content and low crude fat content.In addition,the detection rate of unqualified trace element content in the five feeds was high,mainly the iron and iodine contents.Conclusion The conventional nutrient quality of different experimental animal feed manufacturers can basically meet the national standard requirements,but lack of monitoring of trace elements and other indicators,resulting in high product failure rate.Therefore,it is also necessary to strengthen and improve the construction of feed standardization system and quality control supervision and other key links to ensure the standardization and standardization of laboratory animal feed.
