Method for adding lucid ganoderma to assist fermentation of straw silage feed

Abstract

The invention discloses a method for adding lucid ganoderma to assist fermentation of a straw silage feed. The method comprises the following steps: (1) performing activation and enlarge cultivation of a bacterial strain: inoculating the lucid ganoderma to a fungus solid culture medium, restoring a strain in a flat plate, namely activating for the first time; inoculating the strain which is activated in the flat plate to a fungus liquid culture medium to perform activating for rhe second time to obtain a uniform bacterial suspension; inoculating the bacterial solution which is activated for the second time in a liquid fermentation tank, keeping ventilation, and fermenting to obtain fermentation liquor comprising uniformly suspended hyphae; (2) inoculating and fermenting the straw silage feed: inoculating the fermentation liquor comprising uniformly suspended hyphae into a fermentation substrate of straws, fermenting in a sealing manner, placing for 15-60 days at a normal temperature to obtain the straw silage feed. The method is simple to operate and not high in selectivity to the fermentation substrate; in addition to meeting needs of acidity, straw storage, feeding palatability and the like, the straw silage feed obtained by fermenting further can be used for greatly shortening the fermentation period, reducing the fermentation cost and increasing the nutrients of the straw silage feed.

Description

technical field [0001] The invention relates to the field of silage, in particular to a method for adding Ganoderma lucidum to assist fermentation of straw silage. Background technique [0002] The world's annual output of straw is about 2-3 billion tons, and China's annual output of various crop straws is about 700 million tons. However, due to various reasons, more than 1 / 3 of the straw is discarded or directly burned, causing serious environmental pollution. It also caused a great waste of resources. [0003] Plant straw contains rich nutrients and is suitable for fertilizer or feed utilization. Although straw can be directly fed to livestock, the straw itself has poor taste and low nutritional value, or livestock do not like to eat it due to aging, dryness and other reasons. In the natural state, the crude protein content of crop straw is low, generally 3-5%, and the quality is not good; the crude fiber content is too high, the digestibility is low, and the palatabilit...

Problems solved by technology

[0006] Natural fermentation is mostly used in the production of silage, but the straw itself has very few lactic acid bacteria and its own nutritional content is limited, which cannot guarantee that lactic acid bacteria will become the dominant flora during the fermentation process, and the most beneficial component of silage is L-lactic acid. Content is not high , so the quality of the produced silage is not good

At home and abroad, the research on special additives for silage has been relatively active, but the addition is mostly limited to aerobic bacteria and facultative lactic acid bacteria to improve the level of lactic acid fermentation, and the effect on the production cycle and quality improvement of silage is not ideal.
