To meet the sustainable development of the swine feed industry, it is essential to find alternative feed resources and develop new feed processing technologies. Distillers dried grains with solubles (DDGS) is a by-product from the ethanol industry consisting of adequate nutrients for swine and is an excellent choice for the swine farming industry. Here, a strategy of co-fermentation of DDGS and lignocellulosic feedstocks for production of swine feed was discussed. The potential of the DDGS and lignocellulosic feedstocks as feedstock for fermented pig feed and the complementary relationship between them were described. In order to facilitate the swine feed research in co-fermentation of DDGS and lignocellulosic feedstocks, the relevant studies on strain selection, fermentation conditions, targeted metabolism, product nutrition, as well as the growth and health of swine were collected and critically reviewed. This review proposed an approach for the production of easily digestible and highly nutritious swine feed via co-fermentation of DDGS and lignocellulosic feedstocks, which could provide a guide for cleaner swine farming, relieve stress on the increasing demand of high-value swine feed, and finally support the ever-increasing demand of the pork market.
为了满足猪饲料行业的可持续发展，寻找替代饲料资源和开发新的饲料加工技术至关重要。酒糟干燥颗粒（DDGS）是乙醇工业的副产品，含有猪所需的充足营养成分，是养猪业的绝佳选择。在这里，讨论了一种用 DDGS 和木质纤维素饲料原料共发酵生产猪饲料的策略。描述了 DDGS 和木质纤维素饲料原料作为发酵猪饲料原料的潜力以及它们之间的互补关系。为了便于 DDGS 和木质纤维素饲料原料共发酵的猪饲料研究，收集并批判性地回顾了有关菌株选择、发酵条件、目标代谢、产品营养以及猪生长和健康的相关研究。本综述提出了一种通过 DDGS 和木质纤维素饲料原料共发酵生产易消化和高营养猪饲料的方法，可为清洁养猪提供指导，缓解对高价值猪饲料需求不断增加的压力，最终支持不断增长的猪肉市场需求。
