Pig breeding is an important pillar industry of animal husbandry in China,which generates huge carbon emissions,and has a significant impact on China and even global climate change.Therefore,low-carbon pig breeding is an important way to achieve green and sustainable development of pig industry,and it is urgent to explore technical measures for low carbon pig breeding.Feed production is the source of carbon emission in pig farming system,and is also the most important carbon emission link.The adoption of appropriate nutrition control technology can not only reduce the greenhouse gas emissions from the source of feed production,but also reduce the greenhouse gas production from the subsequent pig intestinal fermentation and manure fermentation,which is of great significance for reducing the carbon emissions of pig breeding.From the perspective of nutritional regulation,this paper reviewed the science and feasibility of the scientific preparation of feed,the biological treatment of feed,the use of additives and the application of unconventional feed raw materials to achieve low-carbon pig breeding,and looked for-ward to the future development of carbon emission reduction in pig breeding.
