The collection, storage, disposal and processing of slaughterhouse by-products is an important part of veterinary care in regions with intensive animal husbandry and meat production. Transmission of diseases and environmental pollution through an improper and/or incorrect handling of slaughterhouse by-products needs to be prevented. The use of animal by-products as feedstuff could be of economical benefit to slaughterhouses and could add nutritive value to animal feed. As a results of the centralisation and intensification of slaughtering, the amount of slaughter by-products produced at a single location is increasing. Until now, hardly any attention, in practice or in research, has been paid to the collection and disposal of these by-products. There are important socio-economic reasons to increase scientific knowledge about the handling of slaughter by-products. Several animal by-products were contaminated with Salmonella. We also showed that rapid breakdown of amino acids in poultry by-products occurs during storage at 20 degrees C. It is concluded that as far as safety, environmental care and nutritive value of animal by-products is concerned, diversification and separation of slaughter by-product collection, storage, disposal and processing is necessary. Measures at source, the slaughterline, and some technologies are suggested for future use.
在集约化畜牧业和肉类生产地区，屠宰场副产品的收集、储存、处理和加工是兽医护理的重要组成部分。必须防止因对屠宰场副产品处理不当和/或不正确而导致疾病传播和环境污染。将动物副产品用作饲料对屠宰场可能具有经济效益，并可为动物饲料增加营养价值。由于屠宰集中化和集约化，单个地点产生的屠宰副产品数量正在增加。到目前为止，在实践或研究中，几乎没有关注这些副产品的收集和处理。增加关于屠宰副产品处理的科学知识有重要的社会经济原因。几种动物副产品被沙门氏菌污染。我们还表明，家禽副产品中的氨基酸在20摄氏度储存期间会迅速分解。得出的结论是，就动物副产品的安全性、环境保护和营养价值而言，有必要对屠宰副产品的收集、储存、处理和加工进行多样化和分离。建议今后采用源头、屠宰线的措施以及一些技术。
