Intestinal health improving and nutrient absorption promoting feather hydrolysis powder feed for litopenaeus vannamei breeding and preparation method thereof

Abstract

The present invention discloses an intestinal health improving and nutrient absorption promoting feather hydrolysis powder feed for litopenaeus vannamei breeding and a preparation method thereof. The feed can improve the colonization ability of probiotics in the intestinal tract of litopenaeus vannamei, promote the digestion and assimilation process of the litopenaeus vannamei. The feed can enhance the immune function and the disease resistance of the litopenaeus vannamei, and reduce morbidity. The feed has good palatability, and is rich in nutrition and easy to absorb. The feed can enhance the appetite of the litopenaeus vannamei, and increase the growth rate of the litopenaeus vannamei.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a feather hydrolyzed powder feed for Litopenaeus vannamei cultivation that improves intestinal health and promotes nutrient absorption and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the global intensive farming industry, the shortage of feed protein resources has become more and more serious. Especially in my country, the lack of feed protein resources has become a restrictive factor for the development of the feed industry, animal husbandry, and aquaculture. It is necessary to broaden the source of protein and find a new way out for protein production. As a result, some unconventional protein resources have attracted widespread attention from all over the world. The feathers of poultry are a rich and good source of protein, but because the keratin contained in them is very stable, it is difficul...

AI Technical Summary

Problems solved by technology

At present, the existing feather meal processing technology cannot solve the problems of serious feather odor, poor palatability, and low digestibility, which greatly hinders the use and promotion of feather meal feed

[0004] The feather meal processing technology disclosed in "The Influence of Deep Processing Technology on the Quality of Feather Meal and Blood Meal" cannot be used due to the lack of disinfection and deodorization treatment before production, deep-level modification treatment in the production process, and nutritional enhancement treatment after production. The texture, taste and flavor of the feed are better improved, and the conditioning and adjustment of animal physiological functions cannot be achieved, which is not conducive to the improvement of animal production performance and breeding benefits
