Forage mulberry, microbial fermentation method, mutton sheep concentrate supplement and preparation method

Abstract

The invention provides forage mulberry, a microbial fermentation method, a mutton sheep concentrate supplement and a preparation method. The microbial fermentation method of the forage mulberry comprises the following steps that: S1, the forage mulberry is dried until the water content is 30 to 35 percent, and is crushed to pass through a 40-mesh sieve; then, 0.5 to 1 percent of cellulose compoundenzyme is sprayed on 99 to 99.5 percent of the forage mulberry; uniform mixing is performed; placement is performed for 3 days under the condition of 35 to 45 DEG C; a forage mulberry cellulose enzymolysis pretreatment material is obtained; S2, 5 to 10 percent of corn shorts and 1 to 2 percent of molasses are added into 86 to 93 percent of the forage mulberry cellulose enzymolysis pretreatment material prepared according to step S1; the pH is regulated to be 6.5 to 7.5; 1 to 2 percent of a mixed bacteria solution is sprayed in a mist spray way; under the condition that the temperature is 35 to 40 DEG C, compaction is performed, and closed fermentation is performed for 5 to 7 days; first fermented forage mulberry is obtained. Compared with forage mulberry in the prior art, the forage mulberry provided by the invention has the advantages that the content of crude fibers is reduced; the content of crude protein is increased.

Description

technical field [0001] The application relates to the technical field of feed, in particular to a protein mulberry and a microbial fermentation method, a mutton sheep concentrate supplement and a preparation method. Background technique [0002] Protein mulberry is also called fodder mulberry. It has the characteristics of strong stress resistance, drought resistance, barren resistance, and salt-alkaline resistance. It can be harvested many times a year. It is a high-yield tree species. The protein content of branches is also as high as 20% to 28%, which is higher than that of high-quality protein pasture alfalfa, and is a very high-quality protein feed material. However, the problem of protein mulberry is that the content of crude fiber is high, and it contains some anti-nutritional factors, such as tannin, defense protein and some unknown enzyme inhibitors, etc., which will affect the digestion and absorption and metabolism of nutrients by animals. To a certain extent, it...

Problems solved by technology

However, the problem of protein mulberry is that the content of crude fiber is high, and it contains some anti-nutritional factors, such as tannin, defense protein and some unknown enzyme inhibitors, etc., which will affect the digestion and absorption and metabolism of nutrients by animals. Limit the utilization of protein mulberry to a certain extent

[0003] In the prior art, protein mulberry is used to directly feed animals after harvesting, or to add freshly dried and crushed protein mulberry to animal feed, but this cannot eliminate or reduce the adverse effects of crude fiber on animals

In addition, the traditional protein mulberry will cause the loss of crude protein during the drying process
