Problems solved by technology

Because macromolecules such as crude fiber and crude protein are not easy to decompose, the nutrient utilization efficiency of feeding pigs directly with mulberry leaves is low. The use of modern microbial fermentation technology can better solve this problem. In the modern industry of producing feed for pigs, the amount of mulberry leaves picked is huge, and the existing microbial fermentation technology has the problem of long fermentation time. If rapid fermentation treatment can be realized, the process time can be shortened, production efficiency can be improved, and raw material crowding can be avoided. pressure, which can reduce the investment in fermentation facilities

Embodiment 1

[0005] (1) Compound fermentation agent preparation (microbial biomass ratio) Yeast: Aspergillus: Lactic acid bacteria = 10:5:1

[0006] (2) Mixed fermentation: Weigh 100kg of leaf powder, 1.5kg of corn flour, add 5kg of yeast solid koji and aspergillus solid koji powder, 2.5L of lactic acid bacteria liquid fermentation agent, and finally add water and mix well, the water content is 40-60 %, put the fermented material into the fermenter for compaction, and cover it tightly with plastic cloth to seal it. Ferment at room temperature for 36 hours.

[0007] (3) Drying and crushing: After the fermentation is finished, the fermented material is dried at 60-70°C, with a moisture content of less than 15%, and then crushed to 80 meshes, which can be used as protein feed to prepare full-price compound feed.

Embodiment 2

[0009] (1) Compound fermentation agent preparation (microbial biomass ratio) Yeast: Aspergillus: Lactic acid bacteria = 10:5:1

[0010] (2) Mixed fermentation: Weigh 100kg of leaf powder, 3kg of corn flour, add 7.5kg of yeast solid koji and aspergillus solid koji powder, 4L of lactic acid bacteria liquid fermentation agent, and finally add water and mix well, the water content is 40-60% , put the fermented material into the fermenter for compaction, cover and seal with plastic cloth. Ferment at room temperature for 48 hours.

[0011] (3) Drying and crushing: After the fermentation is finished, the fermented material is dried at 60-70°C, with a moisture content of less than 15%, and then crushed to 80 meshes, which can be used as protein feed to prepare full-price compound feed.

Embodiment 3

[0013] (1) Compound fermentation agent preparation (microbial biomass ratio) Yeast: Aspergillus: Lactic acid bacteria = 10:5:1

[0014] (2) Mixed fermentation: take by weighing 100kg of leaf powder, 6kg of corn flour, add 10kg of yeast solid koji and aspergillus solid koji powder, 5L of lactic acid bacteria liquid fermentation agent, finally add clear water and mix well, the water content is 40-60%, Put the fermented material into the fermenter for compaction, and cover it tightly with plastic cloth to seal it. Ferment at room temperature for 72 hours.

[0015] (3) Drying and crushing: After the fermentation is finished, the fermented material is dried at 60-70°C, with a moisture content of less than 15%, and then crushed to 80 meshes, which can be used as protein feed to prepare full-price compound feed.

Abstract

The invention relates to a method for quickly fermenting paper mulberry leaves to produce a protein feed. Paper mulberry leaf powder is used as a main nitrogen source raw material, corn meal is used as a carbon source raw material, and the paper mulberry leaves are quickly converted into the protein feed through a complex microorganism mixing solid fermentation technology. The method is mainly characterized in that: the corn meal is taken as a carbon source, so the decomposition conversion of microorganisms on the paper mulberry leaves can be speeded up, the production time is obviously shortened, the production efficiency is improved, and the fermentation facility investment is reduced. The proportion of the corn meal and the paper mulberry leaf powder 1-6 / 100, the protein content of the obtained protein feed after the conversion is larger than 28%, the carbohydrate content is less than 40%, the crude fibre content is less than 9%, the crude fat content is less than 4%, the LD 50 is more than 16g / kg, so the method is safe and non-toxic.

Description

technical field [0001] The invention relates to a method for rapidly fermenting and transforming tree leaves into protein feed. Background technique [0002] Paper mulberry (Broussonetia papyrifera) is a deciduous tree. The protein content of its leaves is very prominent among common forage trees. It is a folk tradition to feed pigs with paper mulberry. Because macromolecules such as crude fiber and crude protein are not easy to decompose, the nutrient utilization efficiency of feeding pigs directly with mulberry leaves is low. The use of modern microbial fermentation technology can better solve this problem. In the modern industry of producing feed for pigs, the amount of mulberry leaves picked is huge, and the existing microbial fermentation technology has the problem of long fermentation time. If rapid fermentation treatment can be realized, the process time can be shortened, production efficiency can be improved, and raw material crowding can be avoided. pressure, which...
