Embodiment 1

[0013] Example 1. Steam explosion pretreatment effect of beer lees

[0014] The pressure for pretreatment of beer lees steam explosion is 2Mpa, and the treatment time is 1min. The neutral detergent fiber (NDF) of the brewer's grains before blasting was 67.8% and 45.9% after blasting, a decrease of 21.9%. The fiber reduction effect was very significant.

Embodiment 2

[0015] Example 2. Comparison of effects of different fermentation methods

[0016] Fermentation conditions: ratio of material to water 1:1, temperature 30℃, mixed bacteria (Aspergillus niger: Candida utilis = 1:1, total number of colonies is 1.3×10 11 cpu / g) The inoculation amount is 0.05% of the weight of dry brewer's grains and / or 0.05% compound enzyme is added, and the fermentation time is 4 days. Among them, the composition and activity of the composite enzyme are β-glucanase, with an activity> 4 million U / g composite enzyme; xylanase, with an activity> 2 million U / g composite enzyme; cellulase, CMC enzyme activity> 200,000 U / g compound enzyme; papain, activity> 20,000 U / g compound enzyme; the ingredients are mixed evenly according to the activity value, and each ingredient is directly purchased on the market, as long as the activity meets the above requirements.

[0017] The different fermentation methods are:

[0018] A: Unexploded beer lees, no fermentation;

[0019] B: Unexpl...

Embodiment 3

[0031] Example 3. Comparison of feeding experiment

[0032] The fattening pig feed produced by the present invention is as shown in the diet formula of the fattening pig feed shown in Table 3. The feeding experiment was carried out at the Beijing Tongzhou farm. After the fermentation of beer lees, it was mixed with other ingredients and then fed directly. The feeding cycle was 84 The effect of feeding experiment is shown in Table 4.

[0033] Table 3 Dietary formula of fattening pig feed

[0034]

[0035] Using the fattening pig feed of the present invention reduces the feed-to-weight ratio by 7.1% on average, and the daily gain of the fattening pigs is increased by 4.6%, and the feed intake and growth of the fattening pigs of the test group are not significantly different from the control.

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 for fattening pig feed by adding brewer's grains by using beer to produce by-product brewer's grains and waste yeast powder. 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 ingredients has become more and more prominent, and the cost of feed has also become higher. In the beer production process, a large amount of wastes such as brewer's grains and waste yeast are generated. The brewery usually sells the lees directly to farmers in the form of wet lees, or feeds it to ruminants (cattle) as roughage after drying. However, the fiber content in beer lees is high, and its protein quality is poor, and it is not easy to digest. If it is added in a large proportion in the ...
