Feed additive for jian carp

Abstract

The invention discloses a feed additive for jian carp. The feed additive consists of the following components in part by weight: 0.03-0.05 part of vitamin C polyphosphate, 0.53-0.73 part of inositol, 0.136-0.164 part of organic iron, 0.061-0.078 part of organic zinc, 1.3-1.5 parts of mannan oligosaccharide, 5.6-6.3 parts of conjugated linoleic acid and 4.1-5.5 parts of glutamine. According to the feed additive, the digestive absorption capability of the jian carp can be enhanced; the resistance of fish body diseases is enhanced; the utilization efficiency of the feed is increased; the excretion of N and P is reduced; the culture water quality is improved; diseases are reduced; the drug application amount is remarkably reduced. feed resources are saved; the fish-culturing benefit is increased; and the green healthy culture of the jian carp is guaranteed.

Description

technical field [0001] The invention relates to a feed additive for aquatic animals Jian carp, in particular to a feed additive for improving the digestion and absorption capacity of Jian carp and the utilization rate of nutrients, and enhancing disease resistance. Background technique [0002] Fish products have high nutritional value, which is very important for improving dietary structure and improving human health. With the increasing awareness of health, consumers have higher and higher requirements for the consumption demand and quality of aquatic products. Carp is the main freshwater aquaculture fish in my country, accounting for 18-20% of the total fish aquaculture output, mainly for artificial feed aquaculture. Among them, Jian carp is the most important species of carp cultured in my country, accounting for about 1 / 2 of the total production of carp cultured in the country, reaching 1.3 million tons in 2010. Jian carp is a new species of fish artificially bred in ...

AI Technical Summary

Problems solved by technology

At present, the problems existing in the production of artificial feed breeding are becoming more and more prominent, mainly: the water quality deteriorates seriously, the growth rate of fish decreases, and the cost of breeding increases; the incidence of disease and mortality increases greatly, and the risk of breeding increases; increase, affecting food safety

The main reasons are: 1. The digestion and absorption ability of fish is weak, and a large amount of undigested nutrients in the feed are discharged into the water, resulting in deterioration of water quality; 2. Fish disease resistance is very weak, and it is easy to be infected by pathogens, outbreaks of diseases, and death Increased rates and doses

However, in the current Jian carp breeding production, there is a lack of feed additive technology that can improve fish digestion and absorption and nutrient utilization efficiency, and enhance fish body disease resistance. It cannot fundamentally solve the problem of water quality deterioration, frequent fish diseases, drug abuse and The problem of drug residues has seriously affected the green and healthy breeding of Jian carp
