| Abstract: |
| 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. |
