摘　　要：试验利用黑曲霉进行固态发酵茶叶渣,选择玉米皮、麸皮、豆粕、菜籽粕、高粱、米糠6种辅料生产发酵饲料,研究不同辅料茶叶渣固体发酵饲料的营养水平,并测定黑曲霉和所选辅料的最优配比。结果表明:豆粕最适合生产茶叶渣固体发酵饲料,黑曲霉发酵剂与豆粕的最适添加量为1.0%、20%,发酵茶叶渣的粗蛋白质、粗纤维、粗灰分、钙、磷、茶单宁含量分别为30.60%、11.40%、4.05%、1.03%、0.42%、4.60%。The experiment uses Aspergillus niger for solid-state fermentation of tea dregs, selects corn husks, bran,soybean meal, rapeseed meal, sorghum and rice bran to produce fermented feeds. The nutritional levels of solid fermented feeds of tea dregs with different auxiliary materials are studied. Optimal ratio of Aspergillus niger and auxiliary materials are determined. The results showed that soybean meal is most suitable for producing solid fermented tea dregs. The optimum addition amount of Aspergillus niger starter and soybean meal are 1.0% and 20%. The content of crude protein,crude fiber, crude ash, calcium, phosphorus and tea tannins are 30.60%, 11.40%, 4.05%, 1.03%, 0.42%, 4.60%, respectively.
