Edible fungus processing feed capable of improving utilization rate of ruminants for rape stalks and preparation method of edible fungus processing feed

Abstract

The invention discloses an edible fungus processing feed capable of improving utilization rate of ruminants for rape stalks. The edible fungus processing feed is prepared from 1%-10% of wheat, and 90%-99% of rape stalks and edible fungus. The invention further discloses a preparation method of the edible fungus processing feed. The rape stalks are processed by the edible fungus used by the method; after solid fermentation for 25-75 days, the CP content of the rape stalks, and the degradation rate of nutrients such as DM, OM, NDF, ADF and ADL can be significantly improved; the in-vitro rumen digestibility and the enzymatic digestion rate of organic substances of the rape stalks, and the activity of manganese peroxidase in a fermentation liquid are improved; and the content of a beneficial component chitin in the rape stalks is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural feed processing, and in particular relates to an edible fungus-treated feed for improving the utilization rate of rape stalks. The invention also relates to a preparation method of the feed. Background technique [0002] my country has a large planting area of ​​rapeseed and rich rapeseed straw resources. Rapeseed straw contains a large amount of carbohydrates such as cellulose and hemicellulose, and is an important source of feed for ruminants. However, in production, rapeseed straw is not widely used in animal husbandry, and most of it is directly burned or decomposed and returned to the field, which not only wastes resources, but also seriously pollutes the environment. The reason is that rape straw has a high degree of lignification, rough straw, and poor palatability; lignin and cellulose in rape straw form a strong ester bond structure, which is difficult for rumen microorganisms to d...

Problems solved by technology

However, in production, rape straw is not widely used in animal husbandry, and most of it is directly burned or decomposed and returned to the field, which not only wastes resources, but also seriously pollutes the environment

The reason is that rape straw has a high degree of lignification, rough straw, and poor palatability; lignin and cellulose in rape straw form a strong ester bond structure, which is difficult for rumen microorganisms to degrade

If not processed, it will affect animal feed intake and reduce production performance

At present, acidification and alkalization are mostly used to treat rape straw, but the residual acid and alkali will cause harm to the animals themselves and pollute the environment.

However, there is no report on the treatment of rapeseed straw by this type of bacteria.
