Problems solved by technology

However, the fiber content in brewer's grains is high, and its protein quality is poor and difficult to digest. If it is added in a large proportion in pig rations, it will affect the growth and development of pigs

Embodiment 1

[0013] Embodiment 1, brewer's grain steam explosion pretreatment effect

[0014] The pressure of brewer's grain steam explosion pretreatment is 2Mpa, and the treatment time is 1min. The neutral detergent fiber (NDF) of brewer's grain before blasting was 67.8%, and it was 45.9% after blasting, which decreased by 21.9%, and the effect of fiber reduction was very remarkable.

Embodiment 2

[0015] Embodiment 2, the effect contrast of different fermentation methods

[0016] Fermentation conditions: material-to-water ratio 1:1, temperature 30°C, mixed bacteria (Aspergillus niger: Candida utilis=1:1, the total number of colonies is 1.3×10 11 cpu / g) inoculum amount is 0.05% dry brewer's grain weight and / or add 0.05% compound enzyme, and the fermentation time is 4 days. The composition and activity of the complex enzymes are β-glucanase, activity>4 million U / g compound enzyme; xylanase, activity>2 million U / g compound enzyme; cellulase, CMC enzyme activity> 200,000 U / g compound enzyme; papain, activity > 20,000 U / g compound enzyme; each component is mixed evenly according to the activity value, and each component can be purchased directly in the market, as long as the activity meets the above requirements.

[0017] The different fermentation methods are:

[0018] A: unexploded beer grains, no fermentation;

[0019] B: Unexploded brewer's grains + mixed bacteria for...

Embodiment 3

[0031] Embodiment 3, feeding experiment contrast

[0032] The fattening pig feed produced by the present invention is the dietary formula of the fattening pig feed shown in table 3; Carry out feeding experiment in Beijing Tongzhou farm, carry out mixing with other components after fermentation of brewer's grains, then directly feed, feeding cycle is 84 Day, the effect of feeding experiment is shown in Table 4.

[0033] Table 3 Diet formula for fattening pig feed

[0034]

[0035] Adopting the fattening pig feed of the invention reduces the feed-to-weight ratio by an average of 7.1%, increases the daily gain of the fattening pigs by 4.6%, and has no significant difference in the feed intake and growth of the fattening pigs in the test group and the control group.

Abstract

The invention belongs to a production method for adding brewer grain fattening pannage, which belongs to the technical field of the feed processing. The production method comprises the following steps that: the brewer grain is undertaken the steam explosion pretreatment and is added with mixed bacteria and / or complex enzyme to be undertaken the solid anaerobic fermentation so as to degrade the fiber content in the brewer grain and to improve the soluble nitrogen content of the brewer grain, so the quality is better, and the nutrition is more balanced; then the fermented brewer grain, waste yeast powder, corn meal, soybean meal and pre-mixed material are uniformly mixed to obtain the fattening pannage being added with brewer grain. The source of the brewer grain and the waste yeast is abundant, the nutrition for matching the brewer grain and the waste yeast is balanced, and the cost of the feed can be reduced; and the brewer grain is processed with the steam explosion pre-treatment technology, the enzymolysis technology and the biological fermentation technology, so the fiber content is reduced, the protein quality is improved, and the type of the aminoacid is more abundant; and the production method can reduce the grain ratio, improves the daily gain, reduces the feed compositions, and is free from influencing the feed intake and the growth of the fatty pigs.

Description

technical field [0001] The invention belongs to the technical field of feed processing. In particular, it relates to a production method of adding brewer's grain to fattening pig feed by using brewer's grain by-product of beer production and waste yeast powder to fatten pig feed. Background technique [0002] In the current pig production, the basic composition of the diet is corn-soybean meal. With the vigorous development of the breeding industry, the contradiction between the supply and demand of feed raw materials is becoming more and more prominent, and the cost of feed is also getting higher and higher. In the process of beer production, a large amount of waste, such as brewer's grains and waste yeast, will be generated. Brewers usually sell the brewer's grains directly to farmers in the form of wet grains, or dry them as roughage for ruminants (cattle). However, the fiber content in brewer's grains is high, and its protein quality is poor and difficult to digest. If...
