Method for preparing feed with mushroom residues and chicken manure as basic components

Abstract

The invention discloses a method for preparing feed with mushroom residues and chicken manure as basic components. The method includes steps: raw material pretreatment, to be specific, removing plastic wraps from the mushroom residues, crushing, mixing with fresh chicken manure, well stirring, feeding into drying equipment, and performing sterilization and moisture reduction treatment; expansion treatment, to be specific, adding water into a pretreated mixture, adjusting to a moisture content suitable for expansion, and sending into expansion equipment for expansion equipment; mixing before fermentation, to be specific, cooling an expanded material to the ambient temperature after expansion treatment, adding EM bacterial fluid and nutritional auxiliary materials, well mixing, and adding water to adjust the mixture in moisture content suitable for fermentation; fermentation, to be specific, hermetically wrapping the mixture before fermentation, and completing fermentation to obtain a product. The method has advantages that pollutants are converted into the feed; after mixing of the mushroom residues and the chicken manure, a carbon-nitrogen ratio is optimized, starch gelatinization is realized through expansion, the crude fiber content is reduced, a fermentation process is accelerated, the nutrient content is increased, nutrient types are enriches, and the digestion rate is increased. The method further has advantages of simplicity in process step and easiness in popularization and application.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to preparing feed with a mixture of fungus chaff and chicken manure. Background technique [0002] Mushroom bran is a by-product of edible fungus cultivation, generally composed of wood chips, wheat bran, corncobs, straw, rice bran, gypsum, etc. my country's edible fungi industry is huge, and in some edible fungus concentrated production areas, the amount of fungus chaff produced is very large. The fungus chaff disposed of as garbage pollutes the environment because of its slow natural degradation. During the cultivation of edible fungi, part of the cellulose and hemicellulose are decomposed to produce a large amount of bacterial protein, which has a certain feed value, but there are low nutrient content, poor palatability, low digestibility and Bacterial contamination etc. [0003] Chicken manure is a major source of environmental pollution in the area where chicken farms are loc...

AI Technical Summary

Problems solved by technology

Due to the low digestibility of chickens, the content of nutrients in chicken manure is still relatively high. Except for the relatively low content of carbon and nitrogen, other nutrients are relatively comprehensive. After treatment, it has the use value as raw materials for other animal feeds, but at present, no chicken manure is used as the main material.

[0004] At present, bacteria chaff and chicken manure are discarded without beneficial transformation treatment, which not only wastes resources, but also pollutes the rural environment
