Abstract

The invention discloses applications of taurine in preparing black carp feed with low fish meal and preparing anti-crowding stress agents for black carps. Through adding 0.1%-0.4% of taurine in the feed with low fish meal (5-10% of fish meal), the content of the fish meal in the carnivorous fish feed can be reduced by about 10%, the anti-crowding stress capacity of fish can be improved, and the cost of the feed can be reduced by more than 300 yuan / ton.

Description

technical field

[0001] The invention belongs to the technical field of aquatic feed, and relates to the application of taurine in carnivorous fish, in particular to the application of taurine in preparing low-meal herring feed. Background technique

[0002] Fish meal has always been an indispensable high-quality protein source in aquatic feed due to its good palatability, high feeding rate, rich content of essential fatty acids and amino acids, low anti-nutritional factors, balanced amino acid composition, and rich content of unknown growth-promoting factors. The increasing shortage of resources and the rising price of fishmeal have caused the cost of formula to rise and the cost of breeding to rise, thus seriously restricting the development of aquaculture industry. Therefore, how to develop low fishmeal feed has become a concern of feed formulators. However, in carnivorous fish, after a large amount of plant protein replaces fish meal, it will cause negative effects such ...
