Preparation method and application of pleurotus eryngii bran fermented feed

Abstract

The invention provides a preparation method and application of pleurotus eryngii bran fermented feed. The feed is prepared from pleurotus eryngii brans, bacterial complex, brans, brown sugar and edible salt. According to the preparation method, the fermenting base material containing the bacterial complex, brans, brown sugar, edible salt and pleurotus eryngii brans is adopted, and is subjected toanaerobic fermentation to obtain bran fermenting feed. Compared with pleurotus eryngii brans, the fermented feed has the advantages that the nutritional structure and flavor are remarkably improved; since the pleurotus eryngii brans do not need drying pretreatment, the fermented feed cannot be easily mildewed or go bad, and can be stored for a long time. The method can be used for reducing the cost for transforming pleurotus eryngii brans into fermented feed along with high transformation efficiency, is favorable to realizing large-scale and resource utilization of bacterial brans, and can beapplied to mutton sheep fattening. The raw materials for preparing the pleurotus eryngii bran fermented feed is not affected by seasons, can be supplied all year; and the preparation procedure is simple, can be easily popularized and applied, and has remarkable economic benefit.

Description

technical field [0001] The invention belongs to the field of microbial fermented feed production technology and mutton sheep breeding, and relates to the production and application of Pleurotus eryngii fungus chaff fermented feed. Background technique [0002] Mushroom chaff is a cultivation substrate for edible fungi using agricultural straw, corncobs, wood chips, cottonseed hulls and other raw materials. In recent years, the output of edible fungi in my country has shown a steady growth trend, and every 1kg of edible fungi produces about 2.5 times as much mushroom chaff as the output of edible fungi. According to the "2015-2016 National Survey Report on Industrialized Production of Edible Fungi", the total output of edible fungi in China in 2016 has reached 2.57×10 7 t, the annual output of fungus chaff is estimated to be about 6.43×10 7 t. The lack of feed raw materials and its cost have always been important factors restricting the development of the aquaculture indus...

Problems solved by technology

[0004] The Chinese patent "Pleurotus eryngii mushroom chaff and non-commercial mushroom body feed and its preparation method and application" (publication number: CN107156444A, publication date: 2017.9.15) discloses a fungus chaff fermented feed for improving pig growth performance , but it needs to dry or pre-dry the pleurotus eryngii chaff with high water content, resulting in long feed production cycle and high cost

In addition, the feed needs to be crushed and passed through an 80-mesh sieve before fermentation, which not only increases the production workload, but also is not conducive to ruminant rumination and maintains rumen pH if the feed is too fine

At present, there is no Pleurotus eryngii chaff fermented feed suitable for promoting the growth performance of mutton sheep that has a short production cycle, low cost, and is suitable for large-scale production.
