Abstract

The invention belongs to the technical field of feed processing, and particularly relates to a straw fermented feed and a production method thereof. The straw fermented feed is prepared from crop straw as a raw material through superfine grinding, natural fermentation, microbial agent fermentation and drying, the content of crude protein is 18-22%, the content of crude fibers is 20-25%, the content of total sugar is 8-10%, the content of water is 8-12%, and the viable count of the microbial agent is larger than or equal to 1 * 10 < 8 > cfu / g. The straw is used as a main raw material, and the straw feed is rich in nutritional ingredients such as protein, fiber and polysaccharide, contains a large number of viable bacteria of microbial agents for fermentation, is fine and uniform in feed particles, has fruity flavor and mellow flavor, can be applied to daily ration of ruminants and non-ruminants, and is short in production cycle, low in production cost, easy in product quality control and suitable for large-scale production. The production process is simple, and industrial production can be realized.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to straw fermented feed and a production method thereof. Background technique [0002] Straw refers to the by-products left after harvesting the seeds of the crops after they mature. It is rich in cellulose, hemicellulose, lignin, and also contains a small amount of crude protein and crude fat. The lignin and hemicellulose are covalently bonded. And embed cellulose in it to form a natural barrier. Although both cellulose and hemicellulose are potentially available resources, the physical-chemical structure and composition factors of straw make straw rough, hard, poor palatability, difficult for animals to digest, and low feed intake, which limits the use of straw in feed. widely used. [0003] In order to break the structural limitation of straw, people have adopted a variety of straw treatment technologies to improve the nutritional value of straw to develop straw feed. T...
