Abstract

The invention discloses a leavening agent and a method for preparing highland barley vinasse fermented feed by using the leavening agent, and belongs to the technical field of feed fermentation. The leavening agent is prepared from the following raw materials in parts by weight: 5-20 parts of a complex microbial inoculant, 2-5 parts of a complex enzyme preparation and 1-3 parts of a fermentation aid, the complex microbial inoculants comprise bacillus subtilis, saccharomyces boulardii and lactobacillus plantarum; the compound enzyme preparation comprises xylanase, cellulase, amylase and pectinase. The highland barley vinasse and the leavening agent are mixed and fermented, so that the highland barley vinasse is converted into an integrated biological fermentation feed of microbial mycoprotein, bioactive small peptide amino acid, microbial active probiotics and a compound enzyme preparation, the effect of enhancing digestion, absorption and utilization is achieved, meanwhile, the flavor of the highland barley vinasse is improved, and the storage time of the highland barley vinasse is prolonged.

Description

technical field [0001] The application relates to a starter and a method for preparing fermented feed from highland barley lees and using the same, belonging to the technical field of feed fermentation. Background technique [0002] Yak is an ancient and primitive breed of cattle in the plateau area. About 90% of the yak in the world live in the Qinghai-Tibet Plateau and the 6 adjacent provinces (Tibet, Qinghai, Sichuan, Gansu, Xinjiang and Yunnan). As the main source of milk and meat for plateau residents, yak has made a huge contribution to the economic development of the region. However, due to various reasons such as history and natural conditions, the production of yak still basically relies on natural grassland and traditional feeding and management mode, and has long been in a vicious circle of "strong in summer, fat in autumn, thin in winter, and dead in spring" for a long time. . Under the traditional feeding mode, the yak is not released until 8-12 years, not onl...
