Problems solved by technology

Due to the addition of new materials, re-cooking and sterilization must be carried out, which not only increases the production cost, but also greatly increases the labor intensity, which is not conducive to the large-scale production of distiller grains in liquor production enterprises.

Abstract

The present invention discloses a kind of active protein feed and its preparation process. The active protein feed is prepared with the materials comprising fresh solid fermented distiller's grains 96-98 wt%, urea 0.5-1 wt%, ammonium sulfate 1-3 wt% and koji tray strain 0.1-0.6 wt%, and the preparation process is simple, low in labor strength and low in cost. The said process can eliminate the pollution caused by distiller's grains while producing loose feed with special fragrance, rich protein, vitamins, amino acid, biotin mineral and nutritious elements essential for animal growth.

Description

technical field [0001] The invention relates to an active protein feed, in particular to an active protein feed mainly prepared by fermenting fresh solid bran distiller's grains as a raw material and a preparation method thereof, belonging to the field of feed. Background technique [0002] From the perspective of biological value, the nutritional value of active protein feed is higher than that of plant protein feed, but lower than that of animal protein feed. It is rich in a large amount of protein, amino acid, biotin, minerals, biological enzymes and other nutrients necessary for the growth of animals. Among them, biological enzymes help animals digest and absorb nutrients in feed, improve the ratio of meat to feed, and can also Effectively alleviate the pollution of animal excrement to the environment. Active protein feed can be widely used as raw materials in various feeds, replacing protein raw materials such as bran and cakes and compound enzymes added to feeds, and ...
