实施清洁生产源头控制畜禽养殖污染

清洁生产作为经济和环境协调发展的一项战略措施，应用于畜牧业在为人类提供安全优质畜产品的同时，还可实现畜禽养殖粪污及其污染物的减排，减少畜牧业对周边环境的污染。本文从饲料调配和饲养管理等方面综述了与畜禽养殖污染物减排相关的清洁生产技术，说明采用低蛋白氨基酸平衡日粮、精准化调配饲料、选择易消化饲料原料、合理应用饲料添加剂、加强环境调控、强化粪污产生管理和优化粪污资源化利用等措施能实现源头减排粪污及污染物的效果，为畜禽养殖污染防控提供理论依据和技术支撑。

Implementation of cleaner production to reduce livestock and poultry pollution at the source

Cleaner production is a strategic measure for the coordinated development of the economy and the environment. Cleaner production applied to livestock breeding not only provides safe, quality products, but also helps to reduce livestock wastes and animal husbandry pollution in the surrounding environment. This paper reviewed cleaner production technologies related to pollutant reduction in livestock breeding from the aspects of feed nutrition and feeding management, which explains the effect of reducing wastes and pollutants at the source using technical measures, such as a low-protein diet based on the balance of amino acids, precise feed allocation, selection of digestible feed raw materials, rational application of feed additives, strengthened environmental regulation, improved manure production management, and optimized manure resource utilization. It provides a theoretical basis and technical support for pollution prevention and control of livestock breeding.
