Embodiment 1

[0020] The quality improver of the invention is mainly composed of inosinic acid, L-carnitine, DMPT, cysteamine hydrochloride and conjugated linoleic acid, and the carrier is zeolite powder. The weight of the quality improver accounts for 0.5% of the perch feed weight, and it is made of the following raw material combination by weight ratio. The component content per kilogram of the improver is: inosinic acid 10g, L-carnitine 50g, DMPT25g, Cysteamine hydrochloride 10g, conjugated linoleic acid 50g, and the rest are zeolite powder.

[0021] Preparation: First, crush the solid raw materials in the raw materials through a 100-mesh sieve; secondly, mix the crushed solid raw materials evenly according to the above ratio; finally, add the liquid raw material conjugated linoleic acid in the raw materials evenly to the mixed solid raw materials , which is a quality improver for sea bass.

Embodiment 2

[0023] The quality improver of the invention is mainly composed of inosinic acid, L-carnitine, DMPT, cysteamine hydrochloride and conjugated linoleic acid, and the carrier is zeolite powder. The weight of the quality improver accounts for 2% of the perch feed weight, and it is made of the following raw material combination by weight ratio, and the component content per kilogram of the improver is: inosinic acid 50g, L-carnitine 15g, DMPT 75g , cysteamine hydrochloride 30g, conjugated linoleic acid 200g, and the rest are zeolite powder.

[0024] Preparation: First, crush the solid raw materials in the raw materials through a 100-mesh sieve; secondly, mix the crushed solid raw materials evenly according to the above ratio; finally, add the liquid raw material conjugated linoleic acid in the raw materials evenly to the mixed solid raw materials , which is a quality improver for sea bass.

Embodiment 3

[0026] In order to verify the effect of the quality improver of the present invention, adopt two kinds of feeds, feed A and feed B, feed A is perch full-price compound feed (Qingdao Xinrenhai Aquatic Feed Technology Co., Ltd.), and feed B is based on the formula of full-price compound feed Add the quality improver prepared by the above-mentioned embodiment, the addition amount is 1% of the weight of the complete compound feed, the feed production process, and the conventional nutritional parameters are the same.

Abstract

The invention relates to a feed additive in aquaculture industry, in particular to a quality improver for weever marine aquaculture and a preparation method of the quality improver. Each kilogram of the improver comprises 10-50g of inosinic acid, 5-15g of L-carnitine, 25-75g of DMPT (dimethylpropiothetin), 10-30g of cysteamine hydrochloride, 50-200g of conjugated linoleic acid and the rest zeolite powder. By the aid of the improver, the inosinic acid content of delicate flavor materials in weever muscles can be effectively increased, the body fat rate of weever can be effectively reduced, fatty acid contents of a weever body are reallocated, unsaturated fatty acid contents are increased, the contents of essential amino acid and delicious amino acid in the weever muscles can be effectively increased, and the shape, the taste and the flavor of the weever can be improved to a certain degree.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a quality improver for sea bass cultured and a preparation method thereof. Background technique [0002] Perch (Lateolabrax japonicus), also known as perch and seven-star perch, is one of the common economic fish species in my country, and it is also a key marine aquaculture species in China. It has very important economic value and is currently the highest-yield mariculture species in my country. With the rapid development of intensive and cage culture and the popularization of compound feed, the yield of perch has increased significantly, but its meat flavor has shown a downward trend, which has seriously affected the quality and industrial development of perch. In the artificial culture of perch, there are generally phenomena such as unbalanced feed nutrition, low protein content, high fat content, and large-scale feeding, resulting in reduced nutritional value of fish, unbal...
