Preparation method for producing fermented feed complex bacterial agent for pigs from vegetable waste and straw

Abstract

The invention relates to a preparation method for producing a fermented feed complex bacterial agent for pigs from vegetable waste and straw. The method comprises steps as follows: (1) a solution A is obtained by evenly mixing milk and brown sugar in proportion; (2) a mixed bacterial solution is firstly added to the solution A, 1 part of inorganic salt is added to 1 L of the solution A, and a solution B is obtained after evenly mixing; (3) corn flour is added to the solution B and evenly stirred, and a raw material with the moisture content being 30%-45% is obtained; (4) the raw material is placed in a container, the container is sealed with a breathable film, fermentation is performed at 28-36 DEG C for 1-2 d, when the pH value is smaller than or equal to 4.5 and 2-20 billons cfu / g mixed bacteria exist, drying, crushing and bagging are performed under the sterile condition, and the fermented feed complex bacterial agent for the pigs is prepared. The process is simple, the cost is low, and the prepared complex bacterial agent can improve the fermentation efficiency, improve the feed quality, reduce nutrition loss and prolong the storage time of fermented feed.

Description

Technical field [0001] The invention relates to the field of pig feed, and in particular to a preparation method of a composite microbial agent for producing fermented feed for pigs from tail vegetables and straw. Background technique [0002] In recent years, the vegetable industry in Gansu has developed rapidly, and has become one of the five major commodity vegetable bases in the country for the "Western Vegetables to the East" and the "Northern Vegetables to the South" and a key production area for export vegetables in the northwest inland. However, with the rapid development of the vegetable industry, a large amount of tail vegetables are produced during the harvesting, fresh marketing and initial processing of vegetables (tail vegetables are vegetable waste, mainly baby cabbage, cabbage, broccoli, celery, lettuce and other vegetables). Discard roots, stems and leaves). In 2016, the province's vegetable planting area reached 8 million mu, and the amount of tail vegetables e...
