Hybrid paper mulberry tree leaf and shoot fermentation feed and preparation method thereof

Abstract

The invention provides a preparation method of a hybrid paper mulberry tree leaf and shoot fermentation feed. The preparation method comprises the following steps of firstly crushing raw materials, performing soaking treatment with alkali, then performing high-temperature boiling, performing cooling and enzymolysis, and finally performing microbial fermentation so as to obtain finished products. The method disclosed by the invention is short in fermentation time, the obtained fermentation feed is high in the content of crude protein, reduced in the content of crude fibers, high in raising efficiency and environmentally-friendly, and animals fed with the fermentation feed grow quickly and are low in attack rate.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a fermented feed of hybrid leaves and twigs and a preparation method thereof. Background technique [0002] From the perspective of long-term development model, compared with foreign countries, my country's agricultural animal husbandry is still a trend of high investment, high growth, high cost, high pollution, and low efficiency. Natural resources have become the main restrictive factors for the development of my country's feed industry. With the improvement of people's living standards, the demand for animal products is also increasing, which has prompted the rapid development of animal husbandry. Feed is the foundation of animal husbandry, and the development of animal husbandry largely depends on the development of feed industry. However, the gap between the supply and demand of conventional feed grains, cakes, and pastures as feed resources has become larger and larger, and ...

AI Technical Summary

Problems solved by technology

[0004] Due to the complex protein structure and high crude fiber content of hybrid leaves, it is difficult for animals to digest and absorb, and more than 80% are excreted from feces, and the feeding efficiency is not high. At present, the research on the use of leaves as feed mainly focuses on the use of biotechnology. On the level of direct fermentation treatment, although direct fermentation can improve the content of crude protein in leaves of mulberry leaves, the crude fiber cannot be effectively degraded, resulting in a low feed utilization rate. To study how to further improve the feeding efficiency of mulberry leaf feed, the present invention aims to Provide a way to improve the feeding value of mulberry feed, further develop mulberry feed resources, alleviate the contradiction of "human and animal competition for food", and promote the sustainable development of animal husbandry
