Problems solved by technology

[0003] Feathers are rich in a variety of essential amino acids for animals, and the protein content reaches 75% to 90%. The feathers that can be collected and utilized in my country reach 200,000 to 300,000 tons every year, and less than 20,000 tons are used for feed after processing. Most of the feathers and animal hair are not Being rationally used not only wastes resources but also pollutes the environment
However, there are still some problems in the research of fermentation at present. The fermentation quality produced by different strains and fermentation process conditions is very different. Therefore, excellent fermentation strains and suitable fermentation process conditions need to be further studied and discussed.

Abstract

The present invention discloses a puffed and fermented protein feed additive and an application thereof. The additive is prepared by the following method as follows: (1) soybean meal, poultry feathers and water are mixed to prepare a mixture, and then the mixture is subjected to a puffing to obtain soybean meal and feather puffed materials; and a mass ratio of the soybean meal and the poultry feathers is 1:(0.5-3.5); and (2) bacillus licheniformis, geotrichum candidum and saccharomycopsis fibuligera are respectively inoculated into a solid fermentation culture medium to conduct fermentation culture at 33-37 DEG C, and after the culture, the cultured materials are dried to obtain the puffed and fermented protein feed additive. The feed additive can improve the feeding value of the soybean meal, fully utilize feather wastes, promote a sustainable development of livestock husbandry, and also alleviate the environmental pollution caused pressure by the domestic poultry feather wastes, and has significant economic and social benefits.

Description

(1) Technical field [0001] The invention relates to a livestock and poultry feed additive, in particular to an extruded fermented protein feed additive and its application. (2) Background technology [0002] Soybean meal is rich in protein, with relatively complete and balanced nutritional components. It also contains bioactive substances such as soybean isoflavones, oligosaccharides, and phospholipids. It is the most widely used vegetable protein raw material in the feed industry. However, there are also a variety of anti-nutritional factors in soybean meal (trypsin inhibitor, soybean antigenic protein, urease, phytic acid, etc.). The absorbed components reduce the digestibility and absorption rate of soybean meal; on the other hand, it can cause damage to some organs in animals, and cause adverse effects on animal physiology, growth, and health, especially in young animals. To give full play to the nutritional value of soybean meal, it is necessary to pre-treat soybean me...
