Problems solved by technology

However, no articles or patents have been found that use these three as fermentation substrates for feed production, and there is no systematic research on these three as fermentation substrates
Furthermore, most of the research focuses on fermentation under laboratory conditions, but there are not many studies on the evaluation of the nutritional value of fermented products, and the system parameters are lacking.

Embodiment 1

[0036] Example 1 Fermentation substrate screening of compound protein feed

[0037] 1. Determination and comparison of various conventional components of the matrix

[0038] made by experiment figure 1 It can be concluded that crude protein content: okara > apple pomace > grape pomace; crude fat content: okara > grape pomace > apple pomace; ash content: okara > grape pomace > apple pomace; neutral cellulose content: okara > grape pomace > Apple pomace; acidic cellulose content: grape pomace > bean pomace > apple pomace, it is planned to use bean pomace as the main ingredient, and apple pomace and grape pomace as auxiliary materials, which is conducive to the complementary effect of conventional nutrients.

[0039] 2. Determination of the ratio of the matrix and the determination of conventional nutritional components

[0040] Dried bean dregs, apple pomace, and grape pomace at 105°C to constant weight, weighed an appropriate amount of the above-mentioned samples, mixed them ...

Embodiment 2

[0043]Example 2 Fermentation enzyme combination screening of compound protein feed

[0044] In the experiment, the compound protein feed (the ratio of the substrate is selected as grape pomace: apple pomace: okara is 2:3:5) was used as the fermentation material for the fermentation experiment. Two microorganisms were selected for the experiment: Saccharomyces cerevisiae and Lactobacillus, and an enzyme solution : Cellulase, for fermentation experiments. Six groups of experiments were designed for the combined screening experiment of bacterial enzymes, namely: blank mixed matrix, fermentation of S. Mass ratio 1:1), Saccharomyces cerevisiae fermentation + Lactobacillus + cellulase fermentation [Saccharomyces cerevisiae fermentation + Lactobacillus, each 2.5%) total 5%, cellulase 5%]. All experiments were fermented for 24 hours at 30°C and the inoculum size was 10%. Finally, the conventional component content of the fermentation product was determined.

Embodiment 3

[0047] Example 3 Fermentation Condition Optimization of Compound Protein Feed

[0048] 1. Determination of fermentation temperature

[0049] In the experiment, the compound protein feed (the ratio of the matrix is ​​selected as grape pomace: apple pomace: bean dregs is 2:3:5) was used as the fermentation material for the fermentation experiment. Three groups of experiments were designed for the fermentation temperature determination experiment, respectively: 30°C, 32.5 ℃, 35℃. The enzyme conditions of all experimental bacteria are: Saccharomyces cerevisiae fermentation + Lactobacillus + cellulase (Saccharomyces cerevisiae fermentation: Lactobacillus mass ratio = 1:1, the inoculum amount of the two is 5% in total, and the amount of cellulase added is 5%). The process is all within 24 hours. Finally, the conventional component content of the fermentation product was determined.

[0050] After different fermentation temperatures and routine component determination of fermentat...

Abstract

The invention relates to a compound protein feed and a preparation method thereof. The compound protein feed is obtained by fermenting bean dregs, grape pomace and apple pomace, inoculated with Saccharomyces cerevisiae, Lactobacillus and cellulase. The crude protein and crude fat content of the fermented compound protein feed is obviously increased, the ash cellulose content is obviously reduced, and the digestibility of crude protein after the animal eats is significantly improved, and the highest digestibility reaches 73.11%. The invention improves the inferior quality of the composite protein raw material through the solid-state fermentation method, improves the protein quality and feed utilization rate, has low cost, can meet the demand of animal husbandry for protein feed, and has good market application prospect.

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,...
