Problems solved by technology

This method is equivalent to splitting and reprocessing the nutritional components of palm meal, and the investment cost of equipment and technology is high, so it is only suitable for professional feed additive manufacturers
[0006] Chinese patent CN 106417897 A discloses a palm meal fermented feed and its preparation method, wherein the fermentation conditions are palm meal: the mixed bacterial liquid: water mass ratio is 1:0.9-1:1.2, and the water content is as high as 70-73 %, close to a fluid form, and the fermentation time is 2-3 days, high-moisture fermentation is prone to mold, and the cost of drying is high, which is not conducive to large-scale production and promotion in actual production
[0007] At present, there is still a lack of a simple method for the preparation of high mannan-oligosaccharide bio-fermented palm meal that is conducive to industrialization and application

Embodiment 1

[0031]Dissolve 2 parts of enzyme preparation, 3 parts of fermentation strains, and 1 part of brown sugar in 50 parts of warm water (30-37℃), mix well to prepare bacteria liquid water; then mix palm meal: bacteria liquid water: warm water according to 1000kg: 56kg : 480kg is mixed uniformly, put into the fermentation tank for accumulation and fermentation for 3 days. After fermentation, the material enters the drum drying equipment, adjusts the inlet air temperature to keep the material temperature at 70-75℃ for drying, crushing, and passing through a 12-mesh sieve Obtain fermented palm meal feed;

Embodiment 2

[0033]Dissolve 3 parts of enzyme preparation, 1 part of fermentation strain, and 1 part of brown sugar in 50 parts of warm water (30-37°C), mix well to prepare bacteria liquid water; then combine palm meal: bacteria liquid water: warm water according to 1000kg: 56kg : Mix 500kg evenly, put it in a thermal fermentation tank, and ferment at 50-55℃ for 1 day. After fermentation, the materials are dried with a tumble dryer, crushed, and passed through a 12-mesh sieve to obtain fermented palm meal feed;

Abstract

The invention provides a preparation method of a high-mannan-oligosaccharide palm meal fermented feed. The preparation method comprises the following steps of mixing an enzyme preparation with fermentation strains, palm meal and water, and performing anaerobic fermentation so as to obtain fermented materials. The preparation method disclosed by the invention is simple to operate, and the preparedpalm meal fermented feed is compounded with various active polysaccharides, small peptides in different molecular weight distributions and a large quantity of probiotics, wherein the content of mannanoligosaccharides reaches 18-25%, the content of the small peptides reaches 16-25%, the content of lactic acid is 2.5-3.5%, and the content of the probiotics is 1.0 * 10<8>cfu / g. The high-mannan-oligosaccharide palm meal fermented feed can promote ingestion of animals, can effectively enhance the immunity of the animals, can guarantee the health of intestinal tracts and can improve the productionperformance.

Description

Technical field[0001]The invention belongs to the field of feed processing technology, and particularly relates to a preparation method of high-mannose-oligosaccharide palm meal fermented feed.Background technique[0002]Palm meal is a by-product of palm kernel dehulling and oil extraction. Its shape and color are similar to rapeseed meal, with a slightly chocolate odor. The content of crude protein and crude fat in palm meal is higher than that of conventional feeds such as corn and bran. In addition, it is rich in mineral elements and vitamins. It can be used as energy feed or combined with other feeds and has good application potential. However, in practical applications, due to its high content of anti-nutritional factors (mainly mannan in non-starch polysaccharides) and crude fiber, low effective energy value, low digestibility and poor palatability, it greatly limits its use in livestock and poultry feed. application.[0003]From the perspective of nutritional characteristics anal...
