生猪低碳养殖的饲喂技术及策略OA

As a crucial part of animal husbandry,pig farming plays a vital role in ensuring national food security,stabilizing meat supply,enhancing farmers'income,and promoting the development of agricultural economy.However,the pig farming industry has become the second largest source of greenhouse gas emissions in animal husbandry,accounting for about 13%of the total emissions,which has a significant impact global on warming.Feed,as the main raw material for pig farming,has a fundamental influence on the greenhouse gas emissions of pigs.Therefore,the scientific and rational optimization of feed utilization is of great significance for reducing the carbon emissions of pig farming and promoting the low-carbon and green transformation of animal husbandry.This paper,based on the perspective of feed utilization,systematically reviewed the breeding technologies and strategies,such as precise feeding technology,amino acid balance in low-protein diets,application of green functional feed additives,and development of unconventional feed ingredients,aimed to provide theoretical references and practical guidance for the low-carbon development of the pig farming industry.
