茶渣经微生物固体发酵成饲料的初步研究

以茶渣为主（70％），添加其它辅料作为发酵基质A，采且本霉、曲霉、有益微生物之间配伍B、不同含水量C和30℃下不同发酵时间D4个因素3个水平的L9（3^4）正交设计进行固体发酵试验，获得A1B3C2D1和A3B2C1D3两组较优发酵条件组合。发酵后料中粗蛋白含量达到26％－29％，分别比对照提高了20％－30％，其营养价值达到了仔猪配合饲料中粗蛋白的含量；可溶性物质达到25％以上，分别比对照提高了20％－37％，经回归分析发酵后饲料中可溶性物质含量与粗蛋白含量呈线性关系。为孤开发利用茶渣废弃物质，开辟了一条新途径。

A Preliminary Study on the Microbial Feed by Solid Fermentation of Tea Residue

Two optimum culture conditions－A3B2C1D3 and A1B3C2D1 were selected with L9(34) orthogonal method using the fermentation substrate which contained tea residue (70%) and others material (30%) A, the proportion of joint－fermentation strains—Trichuderma Viride, Aspergillus, EM B, different volumn of water C and different culture time D at 30℃ by solid fermentation. Under the two optimum conditions, the crude protein content of final product reached 26%～29%, 20%～30% higher than Ck's respectively, its nutritious value satisfied the demand of assorted feed of piglets. And the soluble material's content of final product reached over 25%, 20%～37% higher than CK's respectively. By regression analysis, the correlation between the content of the crude protein and the soluble material int the fermented feed indicated linear relation. And the research open a new path for the utilization of tea residue.
