Process for producing bioprotein feed

Abstract

The invention relates to a process for producing a bioprotein feed, which is characterized by comprising the following steps: selecting slant strain, dried blood, white sugar, bran and brewer's grains according to a certain weight ratio; mixing, stirring, inoculating, carrying out enzymolysis, breeding and drying to manufacture a strain material; and selecting the strain material, dried blood, meat powder, bean pulp, bran, sucrose and slant strain according to a certain weight ratio, mixing, stirring, carrying out secondary enzymolysis, and drying to obtain the finished feed. The strain material is firstly produced, thereby enhancing the biodegrability, promoting decomposition and facilitating even mixing. The product prepared by the process combines the advantages of biological enzymolysis and microbian glycolysis, enables the dried blood and the meat powder to have favorable degradation effect, has the advantages of high digestability, good palatability, balanced nutrition, convenient production, low investment, low production cost, and can be used for replacing 80% of fish meal.

Description

technical field [0001] The invention relates to a production method of feed, in particular to a production process of biological protein feed. Background technique [0002] The content of crude protein in leftovers such as livestock and poultry blood meal and meat meal is more than 80%, and has been used to replace part of fish meal and soybean meal to produce biological protein feed for a long time. The traditional production method is to adopt cooking method, and the product produced has low digestibility, poor palatability, and unbalanced amino acid content. In order to overcome the shortcomings of traditional production methods, at present, cooking, dehydration and drying methods are widely used at home and abroad. Although the nutritional value of the products is better than that of traditional production methods, the investment is large, the production cost is high, and the operation is troublesome.
