Abstract: Miscellaneous meal refers to the by⁃product from oil crops after extraction，including rapeseed meal， cottonseed meal，peanut meal and sunflower seed meal. It has high yield and low price，and is rich in protein，fat， and minerals，which make it a valuable unconventional feedstock. However，the high levels of anti⁃nutritional factors present such as crude fiber，tannins，phytic acid and thioglycoside in miscellaneous meal not only impede the digestion and absorption of nutrients but also have toxicological effects，severely constraining the feed utilization of miscellaneous meal. With the advancement and widespread adoption of biotechnological approaches in animal feed production，fermentation of feed raw materials offers a distinctive advantage. Microbial fermentation facilitates the reduction of anti⁃nutrition factors in miscellaneous meal and breaks down indigestible or poorly utilized components into readily absorbable small molecules，enhancing digestion and utilization efficiency of animals. Currently，lactic acid bacteria，bacillus，yeast，and mold are the predominant microorganisms employed in the fermentation of miscellaneous meals. Fermentation also generates valuable metabolites，providing a rich source of probiotics for animals.Reasonable utilization of miscellaneous meal not only save conventional feed resources，alleviate the shortage of domestic feed resources and the situation of“human and animal competition for food”，but also address environmental pollution caused by waste discharge. Miscellaneous meal has broad application prospects in animal production. This paper reviews the nutritional value of miscellaneous meal，changes in nutritional components and anti⁃ nutritional factors before and after fermentation，as well as the application effect of fermented feed in broiler production. It also summarizes the current challenges in the utilization of miscellaneous meal，in order to provide theoretical basis for the application of fermented miscellaneous meal in broiler production.

摘要： 杂粕泛指除豆粕外的其他饼粕，包括菜籽粕、棉籽粕、花生粕和葵仁粕等，具有产量大、价格低且富含蛋白质、脂肪和矿物质等特点，可作为一种良好的非常规饲料原料。然而，杂粕中粗纤维和单宁、植酸和硫甙等抗营养成分含量较高，不仅会妨碍动物对养分的消化吸收，还会产生毒理作用，这严重限制了杂粕的饲料化利用。随着生物饲料技术的发展与推广，发酵饲料的优势日趋明显。微生物发酵可有效去除杂粕中的抗营养因子，将利用率低的成分分解为易消化吸收的多肽、氨基酸、有机酸等小分子物质，提高动物的消化吸收率。目前，发酵杂粕使用的微生物多为乳酸菌、芽孢杆菌、酵母和霉菌，经发酵后不仅可产生有益代谢物，还可作为动物良好的益生菌来源。研究表明，发酵杂粕在改善肉鸡生长性能、肠道吸收和肉品质等方面的效果较好。合理利用杂粕能达到一物多用，既可节约常规饲料资源、缓解国内饲料资源短缺和“人畜争粮”的局面，又能解决废弃物排放导致的环境污染问题，在养殖生产中具有广阔的应用前景。因此，该文综述了杂粕的营养价值、发酵菌种、发酵前后营养成分和抗营养因子的变化及其发酵杂粕在肉鸡生产中的应用效果，并总结了目前在杂粕利用中存在的问题，以期为发酵杂粕在肉鸡生产中的应用提供理论依据。
