Feather protein peptide feed additive and application thereof

Abstract

The present invention discloses a feather protein peptide feed additive and an application thereof. The preparation method for the feather protein peptide feed additive comprises: 1, mixing a substrate and water to obtain a solid state fermentation culture medium A, inoculating saccharomyces cerevisiae and saccharomycopsis fibuligera in the solid state fermentation culture medium A, culturing for 28-30 hours at a temperature of 30 DEG C, and drying the resulting culture at a temperature of 35-45 DEG C after culturing to obtain a yeast culture; and 2, mixing avian feather powder and the yeast culture, adding water to the resulting mixed material, uniformly stirring to obtain a solid state fermentation culture medium B, respectively inoculating bnfillus licheniformis and bacillus subtilis in the solid state fermentation culture medium B, and carrying out fermentation culture for 30-45 hours at a temperature of 35-38 DEG C to obtain the feather protein peptide feed additive. The feather protein peptide feed additive of the present invention has the following advantages that: feather protein digestion absorption efficiency can be 90%; the additive contains a variety of bioactive peptides, and provides digestion and growth promotion effects; the additive has natural fermentation flavor and good palatability; and pica of livestock and poultry can be significantly improved.

Description

(1) Technical field [0001] The invention relates to a feather protein peptide feed additive and its preparation and application. (2) Background technology [0002] In recent years, the rapid development of the global aquaculture industry characterized by intensification has made a great contribution to the improvement of human living standards, but the serious shortage of feed protein resources has restricted the sustainable development of the aquaculture industry. However, poultry feathers, which are rich in various essential amino acids of animals and have a protein content of 75% to 90%, have not been effectively utilized. In my country, 200,000 to 300,000 tons of feathers can be collected and utilized every year, and less than 20,000 of them are used for feed after processing. Tons, most of the feathers and animal hairs have not been rationally utilized, which not only wastes resources, but also pollutes the environment. The main reason why feathers cannot be used is tha...

[0002] In recent years, the rapid development of the global aquaculture industry characterized by intensification has made great contributions to the improvement of human living standards, but the serious shortage of feed protein resources has restricted the sustainable development of the aquaculture industry.

However, poultry feathers, which are rich in various essential amino acids of animals and have a protein content of 75% to 90%, have not been effectively utilized. In my country, 200,000 to 300,000 tons of feathers can be collected and utilized every year, and less than 20,000 of them are used for feed after processing. tons, most of the feathers and animal hairs have not been rationally utilized, which not only wastes resources, but also pollutes the environment

These methods can improve the digestibility of feather meal to a certain extent, but there are obvious deficiencies, such as unqualified processing technology, low product digestion and absorption rate, uneven quality, resulting in poor breeding effect and poor economic benefits , secondary pollution caused by the treatment process, etc.
