Embodiment 1

[0017] Experimental results of quality improvement of large yellow croaker

[0018] 1. Improve feed preparation. The ingredients are mixed according to the following weight percentages: 20% imported fish meal, 17% fresh fish paste, 9% shrimp powder, 3% scallop powder, 5% fermented soybean meal, 9% peeled soybean meal, 3% yeast protein, 1% soybean lecithin, Calcium dihydrogen phosphate 1%, high-gluten flour 20%, multivitamin 2.0%, quality improver 2.0%, fish oil 8%. Among them, the quality improver is composed of seaweed extract, cysteine ​​hydrochloride and collagen small peptide at a ratio of 1.5:1:1, the seaweed extract is composed of brown algae extract and salina extract at a ratio of 3:2, and collagen small peptide It is a mixture of collagen peptides of different molecular weights with a molecular weight less than 4.5KDa formed by hydrolysis of collagen derived from terrestrial animals.

[0019] Second, improve the feeding of feed. The juvenile stage is fed 3 times a ...

Embodiment 2

[0042] The ingredients of large yellow croaker quality improvement feed are as follows: 22% imported fish meal, 20.2% fresh fish paste, 8% shrimp meal, 4% scallop meal, 9.5% fermented soybean meal, 6% peeled soybean meal, 3% yeast protein, soybean Phospholipid 1.2%, calcium dihydrogen phosphate 1.3%, high-gluten flour 16.5%, multivitamin 1.1%, quality improver 1.2%, fish oil 6%. Among them, the quality improver is composed of seaweed extract, cysteine ​​hydrochloride and small collagen peptide in a ratio of 1:1:1.

[0043]Further, the quality improver seaweed extract is composed of brown algae extract, salina extract, and microalgae extract at a ratio of 1:1:1. Collagen small peptides are formed after hydrolysis of collagen with different molecular weights less than 3.5KDa. sized collagen peptide blend.

[0044] The feeding method of large yellow croaker quality-improved feed of the present invention is that juvenile stage is fed 3 times every day during the day, and the time...

Embodiment 3

[0046] The ingredients of large yellow croaker quality improvement feed are as follows: 19% imported fish meal, 18% fresh fish paste, 8.5% shrimp meal, 3.5% scallop meal, 4.8% fermented soybean meal, 6.4% peeled soybean meal, 6.5% yeast protein, soybean Phospholipid 4.6%, calcium dihydrogen phosphate 1.2%, high-gluten flour 19.5%, multivitamin 1.6%, quality improver 1.25%, fish oil 5.15%. Among them, the quality improver is composed of seaweed extract, cysteine ​​hydrochloride and small collagen peptide at a ratio of 0.6:1:1.

[0047] Further, the quality improver seaweed extract is composed of brown algae extract and salina extract at a ratio of 1:1.25, and the small collagen peptide is a mixture of collagen peptides of different molecular weights with a molecular weight less than 2.8KDa formed after collagen hydrolysis.

Abstract

The invention discloses a feed for improving the quality of large yellow croakers, and a feeding method of the feed. The feed for improving the quality of the large yellow croakers comprises import fishmeal, fresh fish pulp, shrimp meal, scallop powder, fermented soybean meal, peeled soybean meal, yeast protein, soybean lecithin, calcium dihydrogen phosphate, high gluten flour, multivitamin multi-ore, a quality improver and fish oil, wherein the quality improver comprises two or three selected from a sea algae extract, cysteine hydrochloride and collagen small peptide in a proportion. The invention also discloses the feeding method of the feed. After the feed is used, the content of fat in the muscles of the large yellow croakers can be reduced, so that the lean meat percentage is increased; the contents of delicious amino acid and the like are increased, and especially, the contents of glutamic acid, leucine and aspartic acid are most remarkably increased. After the feed is used, the composition and the content of fatty acid of the large yellow croakers can be increased, and the contents of unsaturated fatty acid as well as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which have important physiological functions are increased, so that the large yellow croakers are relatively good in mouth feel and nutrition and are relatively suitable for the requirements of consumers. Furthermore, the quality improver of the feed is a food or feed additive with a natural source, and thus the advantages of being poisonless, harmless, free of residue in fish bodies, and slight in side effect on the environment can be realized, the feed is in accordance with the requirements of green and healthy aquatic products.

Description

technical field [0001] The invention relates to feed formulation technology for aquaculture, in particular to a feed for improving the quality of large yellow croaker and a feeding method thereof. Background technique [0002] Large yellow croaker is rich in protein, trace elements and vitamins, and has a good tonic effect on the human body. For the weak and middle-aged and elderly, eating large yellow croaker will receive a good therapeutic effect. Large yellow croaker is rich in trace elements Selenium, which can eliminate free radicals produced by human metabolism, can delay aging, and has preventive effects on various cancers, has long been favored by consumers. [0003] However, with the development of high-density intensive farming, people always feel that its quality and flavor are not as delicious as wild fish in nature. Compared with wild fish, the quality of artificially farmed fish is poorer in the following aspects: light skin color, low lean meat percentage of ...
