Fish and shrimp phagostimulant of famented product adhesion protein and its prepn process

Abstract

The fish and shrimp phagostimulant of fermented product and adsorbed protein is prepared through screening beneficial bacteria seed from cultivated animal body, culturing in composite culture medium to proliferate, concentrating and adding plant protein with phagostimulant effect. It is added into fish and shrimp feed to raise their feed intake and improve their digesting function. The production process has combined beneficial microbe fermenting technology and low temperature drying technology to ensure the fast growth of beneficial bacteria, the well preservation of metabolic product and the special cultivating function. The fish and shrimp phagostimulant is one kind of green product capable of replacing traditional phagostimulant and antioxidant.

Description

technical field

[0001] The invention relates to a fish and shrimp food attractant produced by adsorbing protein from fermentation products and a preparation method thereof. By adding it to fish feed, the special fragrance and beneficial bacteria produced by microbial fermentation can be used to improve the intestinal tract and digestive function of aquatic animals, and improve the The feed intake and daily weight gain of animals belong to the technical field of agricultural biological products. Background technique

[0002] Now in aquaculture, in order to pursue the fastest breeding effect and improve the storage time of feed, a large amount of antioxidants such as amino acid, betaine and ethoxyquinoline are added to the feed, which objectively achieves the goal of increasing the breeding output and attracting food. effect, but at the same time it makes the feed produce a strong odor, and betaine and antioxidants are currently chemically produced, and they are enriched in th...
