Biological protein feed and preparation technology thereof

Abstract

The invention discloses a biological protein feed and a preparation technology thereof. With plant cake dregs as a main ingredient and corn meal as an accessory, the biological protein feed is prepared by biological fermentation, wherein crude protein in the feed is greater than or equal to 48.0%, water is less than or equal to 12.5%, lysine is greater than or equal to 2.5%, beneficial bacteria are more than or equal to 5 billion cfu / g, and organic acid is greater than or equal to 3.0%. According to the invention, the plant cake dregs are used as the main raw material, a protein feed with a low nutritional value is converted into a protein feed with a high nutritional value through microbial solid fermentation, and the pressure of lack in the domestic protein feed is relieved to a certain degree. The biological protein feed disclosed by the invention is applied to livestock breeding, and can obviously improve the absorption utilization rate of nutrient substances in the feed by animals, reduce emission of harmful substances such as ammonia gas, hydrogen sulfide, phosphorus and the like in the animal excrement, and obviously reduce the secondary pollution caused by livestock and poultry. The biological protein feed disclosed by the invention can replace the fish meal, yeast and the like in livestock breeding, thus the breeding cost can be obviously reduced.

Description

technical field

[0001] The invention belongs to the technical field of feed, and in particular relates to a biological protein feed and a preparation process thereof. Background technique

[0002] Livestock products (meat, eggs, milk) are the main source of protein for human maintenance. In animal husbandry production, grains, cakes, etc. are commonly used to prepare animal feed, but with the development of animal husbandry production, these conventional feeds are increasingly unable to meet the needs of current animal husbandry production, especially the shortage of protein feed, which has become a limitation for my country's animal husbandry industry. One of the main factors of development. Unconventional protein resources refer to protein resources that have not been used as the main protein feed or used less in traditional animal feed. However, my country's unconventional protein feed resources are large in quantity, with many types and wide distribution. Therefore, ho...
