Abstract

The present invention relates to a kind of single cell protein feed and its production process. Its technical scheme is characterized by that it uses grain or by-product produced by milling engineering as solid culture medium, adds the corn steep liquor and lysine waste liquor, uses any one of zymophyte, candida, distillers' yeast, torula yeast and baidy enzyme or their any combination to make inoculation. Said invention is extensive in raw material source, and its cost is low, and the gross protein value of said feed is up to 35-55%, and it is easily absorbed by livestock and fowl.

Description

Technical field: [0001] The invention belongs to the technical field of feed processing, in particular to a processing technology of protein feed. Background technique: [0002] At present, the production of livestock and poultry feed mostly uses crops as the main raw material, and the waste residues of processed crops such as corn dregs, distiller's grains, and molasses are also used as the main raw materials. The production of livestock and poultry feed with crops as the main raw material can be produced on a large scale, but it requires a large amount of crops and the cost of feed is relatively high. According to the protein classification in the feed, it can also be divided into animal protein (such as fish meal, feather meal) feed, plant protein (such as soybean meal, cottonseed meal, etc.) Feed, such as "Manufacturing Process for Producing Pure Grain Liquor and Feed for Livestock and Poultry by Solid-State Fermentation" (98114359.8), "A Method for Simultaneous Product...
