Abstract

The invention relates to a compound protein feed and a preparation method thereof. The compound protein feed is prepared by the following steps: as bean dregs, grape residues and apple pomace are used as fermentation raw materials, inoculating saccharomyces cerevisiae, lactic acid bacillus and cellulase, and fermenting, thereby obtaining the compound protein feed. According to the fermented compound protein feed, the content of crude proteins and crude fat is obviously increased, the content of ash cellulose is obviously reduced, the digestion rate of the crude proteins eaten by animals is obviously increased, and the highest digestion rate is 73.11 percent. According to the solid state fermentation method, the low quality of the compound protein feed is improved, the quality of the proteins is improved and the feed utilization rate is increased, and the compound protein feed is low in cost, can meet the requirements of animal husbandry on the protein feed and has good market application prospects.

Description

technical field

[0001] The invention relates to a feed, in particular to an easily digestible compound protein feed with relatively high crude protein, crude fat and low ash content and a preparation method thereof. Background technique

[0002] With the rapid development of my country's animal husbandry and feed industry, my country's demand for feed raw materials has increased sharply, making my country's feed resources, especially protein resources, more scarce, and there are also many problems in terms of variety and structure. In recent years, some conventional protein feed raw materials in my country, such as bean dregs, fish meal, meat and bone meal and other high-quality protein, are lacking and prices have risen. few. my country's annual output of cottonseed cake is about 4 million tons, and feeding pigs only accounts for about 16%, most of which are directly used as fertilizers. The annual output of rapeseed cake is about 7 million tons, only 5%-6% is used as feed,...
