Abstract

The invention discloses a biologically fermented straw feed prepared through anaerobic or facultative fermentation. The feed is mainly prepared by mixing the following raw materials by weight: 30-90% of straws, 5-30% of bran, 0.1-0.2% of biological fermentation agent and 0-2% of premix. The invention also discloses a preparation method of the feed. The preparation method is characterized by comprising the following steps: grinding the straws, then adding water into the straws and stirring the materials; adding an ammonizator to carry out ammonification, adding the bran, the biological fermentation agent and the premix into the ammonified straws, fully mixing the materials and adjusting the moisture content to 40-60% of the total raw materials; and then carrying out anaerobic or facultative fermentation and directly obtaining the product after fermentation. The feed has the following beneficial effects: the compound bacteria are adopted for fermentation, thus solving the problem of lowefficiency of single bacterium fermentation and improving the decomposition rate of the straws; the straws are added for changing in a wide range; the universality is improved; and the feed can be gently touched and micro-stored, can be stored for long term and is mainly used as the feed for such herbivores as cattle, sheep, horses, donkeys, rabbits, geese and the like.

Description

technical field [0001] The invention relates to a biologically fermented feed mainly using straw as a raw material, belonging to the technical field of biological fermentation, in particular to a straw biologically fermented feed prepared by anaerobic or facultative fermentation. Background technique [0002] At present, natural grass-fed raw materials can provide carbohydrates for ruminants such as cattle and sheep, that is, grass fiber, lignin, pectin, etc. Decomposing bacteria, proteolytic bacteria, etc.), enzymatically hydrolyze organic matter such as cellulose and hemicellulose into sugar substances, and then synthesize bacterial protein through bacteria to meet the growth needs of cattle and sheep. However, the probiotics in the rumen are limited, and the utilization rate of straw fiber is also limited. [0003] In the prior art, the feed for cattle and sheep based on straw silage and micro-storage is the silage produced by anaerobic storage or adding lactic acid bact...
