Mulberry leaf fermentation feed as well as production method and application thereof

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 lower. 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 met...

Examples

Embodiment 1

[0025] (1) Compound bacterial culture medium: potato 250 g , mulberry leaf powder 50g, glucose 50g, agar 30g, add water to 1500ml, put into conical flask and carry out autoclaving;

[0026] (2) Recovery and expanded cultivation of complex bacteria: take 0.6g of dry powder of complex bacteria of yeast, lactobacillus and aspergillus oryzae (the ratio of yeast, lactobacillus and aspergillus oryzae powder is 1:2:1) into the Step (1) In the Erlenmeyer flask in which the culture solution was sterilized, it was cultured at a constant temperature of 30°C for 30 hours, and placed in a shaker with a rotation speed of 30rpm for 30 hours to obtain a compound bacterial culture solution;

[0027] (3) Production of middle koji: Weigh 5kg of dried mulberry leaf powder, 1kg of bean cake powder, 2kg of wheat bran, and 2kg of corn flour, add 1g of inorganic salt and tap water and mix until the compost is moist, and it is advisable to extrude without water dripping out. Sterilization treatment; ...

[0030] (1) Compound bacterial culture medium: potato 250 g , mulberry leaf powder 50g, glucose 50g, agar 30g, add water to 1500ml, put into conical flask and carry out autoclaving;

[0031](2) Recovery and expanded cultivation of complex bacteria: take 0.5g of dry compound bacteria powder of yeast, lactobacillus and aspergillus oryzae (the ratio of yeast, lactobacillus and aspergillus oryzae powder is 1:2.5:1.5) into the Step (1) In the Erlenmeyer flask in which the culture solution was sterilized, it was cultured at a constant temperature of 30°C for 30 hours, and placed in a shaker with a rotation speed of 30rpm for 30 hours to obtain a compound bacterial culture solution;

[0032] (3) Production of middle koji: Weigh 5kg of dried mulberry leaf powder, 1kg of bean cake powder, 2kg of wheat bran, and 2kg of corn flour, add 1g of inorganic salt and tap water and mix until the compost is moist, and it is advisable to extrude without water dripping out.

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.
