Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a kind of taurine in the existing freshwater carnivorous fish for the negative effects such as the decline of fish growth caused by the use of a large amount of vegetable protein, the reduction of immunity, and the poor anti-stress ability. The addition of low fishmeal herring feed or the application of herring anti-crowding stress agent, and the low fishmeal herring feed containing taurine, the invention can prevent the fish caused by the use of a large amount of vegetable protein in freshwater carnivorous fish Negative effects of reduced growth, reduced immunity, poor stress resistance, reduced feed costs

example 1

[0017] Example 1: Effect of taurine on the growth performance of herring

[0018] Test material: Taurine (purchased from Biochemical Reagent Company), with a purity of 99%, white powder.

[0019] Test location: Hunan Agricultural University Aquaculture Base

[0020] Test feed and grouping: select 360 healthy herrings of the same age with an average weight of (0.62±0.01) g, and randomly distribute them to 4 treatments, which are normal fish meal control group (treatment 1 and treatment 2), taurine supplementation under low fish meal The amount is 0.0%, 0.1% treatment group (respectively is treatment three and treatment four), and treatment four is the feed group of the present invention. Three replicates per group, 30 fish per replicate.

[0021] Table 1 Basic feed composition and nutritional level

[0022]

[0023] When preparing the test feed, each feed material was crushed until it passed through a 40-mesh sieve, and the content on the 60-mesh sieve was less than 20%, ...

[0029] Example 2: Effects of taurine on growth performance, biochemical indicators, digestive enzymes and anti-crowding stress of juvenile herring

[0030] Test material, place, test feed and feeding test method are all described with example one.

[0031] Experimental grouping: Select 450 healthy herrings of the same age with an average weight of (5.90±0.03) g, and randomly distribute them to 5 treatments, respectively high fish meal control group, low fish meal case with taurine addition of 0.0%, 0.1%, 0.2 %, 0.4% of the treatment group (I 0 Indicates adding 0% group, I 0.1 Indicates adding 0.1% group, I 0.2 Indicates adding 0.2% group, I 0.4 Indicates the addition of 0.4% group, the same below). Three replicates per group, 30 fish per replicate.

[0032] After the feeding experiment (eight weeks) is over, according to the growth situation, select 4 representative groups, control group, no taurine added group I 0 , the best growth group I 0.1 and high levels of taurin...

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 ...
