Problems solved by technology

At the same time, our research has found that, except for a small number of animals such as cattle, sheep, and rabbits, when mulberry leaves are used as feed for livestock, poultry, and fish, there are problems of poor palatability and low apparent digestion of crude protein, crude fat, and amino acids.

Embodiment 3

[0035] Mix the fermented and mature mulberry leaf feed ingredients obtained in Example 1-2, corn, soybean meal, and premix at a ratio of 10:65 to 75:10 to 20:5, and feed pork pigs over 40 kg with a daily feed intake of 1.6 to 2.8kg, compared with the feed without adding the fermented and mature mulberry leaf feed ingredients of Example 1-2 as the feed additive, the pigs eat faster, the feed intake increases by about 1-1.5%, and they are active.

Abstract

The invention provides a mulberry leaf feed as well as a processing method and application of the mulberry leaf feed. According to the mulberry leaf feed, dry mulberry leaf powder is artificially fermented by virtue of screened mixed bacteria of saccharomycetes, lactobacilli and aspergillus oryzae, so that the mouth feel of the mulberry leaf powder can be well improved, the ingestion capability of feed animals can be improved, and the apparent digestibility of the feed can be improved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a production method for artificially fermenting feed ingredients using mulberry leaf powder. Background technique [0002] With the expansion of breeding scale in our country, there has been a serious shortage of plant protein sources. The nutritional value of mulberry leaves is very rich, and the protein content is similar to that of alfalfa, 80% to 100% higher than that of grasses, and 40% to 50% higher than that of tropical legumes. Depending on the species, age and growth conditions of mulberry trees, the crude protein content of mulberry trees is 15% to 28%, which is similar to that of most legume pastures, but its crude fiber content is low. Mulberry leaves are rich in a variety of amino acids with an appropriate ratio, among which the content of glutamic acid is the highest (glutamic acid plays an important role in the process of sugar metabolism and protein metab...
