Problems solved by technology

However, the leaf protein is mainly crude protein and has a lot of crude fiber. As a single feed, the absorption and utilization rate of livestock and poultry is low.
[0003] Yellow distiller's grains are by-products of winemaking, containing a large amount of water-insoluble gluten, and can only be used as low-value feed, and are not resistant to storage, and even rotten and pollute the environment

Abstract

The present invention relates to one kind of high protein feed produced through mixing and fermenting paper-mulberry leaf and distiller's grains and its production process. The production process includes the following steps: stoving and crushing paper-mulberry leaf into powder; mixing yellow wine residue and water, sterilizing, cooling, adding aspergillus and candidia strain and fermentation culturing to obtain fermenting yeast; mixing paper-mulberry leaf powder, pressed yellow wine residue and water to form solid fermenting material, inoculating the fermenting yeast to ferment; and stoving and crushing or pelletizing the fermented material to produce the feed. The high protein feed product contains protein in 23-45 wt%, carbohydrate in 42-48 wt%, crude fiber in 6-7 % and lysine in 2 wt%, as well as rich vitamin B and beneficial enzymes, and is one excellent kinds of feed for farm animals.

Description

technical field [0001] The invention relates to a method for preparing high-protein feed by mixed fermenting the leaves and distiller's grains. Background technique [0002] Paper mulberry, also known as mulberry tree, is a deciduous tree (Broussonetia papyrifera (L.) vent) of Moraceae. The protein content of mulberry leaves is as high as 20-30%, and it is also very rich in vitamins, carbohydrates and trace elements. It has long been a habit to use mulberry leaves to feed pigs, cattle and sheep. In recent years, a large number of popularization and cultivation of mulberry trees, only the branches are used as industrial raw materials for papermaking, while the protein-rich leaves are either discarded or only sporadically used as folk pig feed. However, the leaf protein is mainly crude protein and has a lot of crude fiber. As a single feed, the absorption and utilization rate of livestock and poultry is low. [0003] Yellow distiller's grains are by-products of winemaking, c...
