Abstract

The invention discloses a feed containing highly unsaturated fatty acid used for improving the growth performance and meat quality of epinephelus coioides. The feed comprises the following componentsin percentage by weight: 55-65% of protein-source raw material, 6-10% of fat-source raw material, 2-4% of water-soluble dietary fibers, 1-5% of compound vitamins, 1-5% of compound mineral salts, 4-10%of an adhesive, 0.1-1% of choline chloride, 0.1-1% of vitamin C phosphate and the balance of sugar-source raw material, wherein the fat-source raw material is vegetable oil containing DHA and EPA, the total amount of the DHA and the EPA is 1-2% of the feed by weight, and the dosage ratio of the DHA to the EPA is (1-4):1. By adjusting the formula of a feed for epinephelus, the feed of the invention can obviously improve the growth performance and the nutritional value of the epinephelus, and has a good popularization value and application prospect.

Description

technical field [0001] The invention relates to the technical field of grouper feed, in particular to a feed containing high unsaturated fatty acids that improves the growth performance and meat quality of grouper. Background technique [0002] Grouper is one of the important high-grade marine cultured fish in my country. It has the advantages of fast growth, high survival rate, and high-density breeding. Its commercial fish meat is smooth and tender, delicious and nutritious. With the growing maturity of large-scale artificial breeding technology of grouper, artificial breeding of grouper has developed vigorously in Hainan, Fujian, Guangdong and other provinces. [0003] Lipids have important biological functions and physiological regulatory functions in the body: they are not only the energy storage of organisms, but also important substances that constitute biofilms, which are closely related to cell recognition and tissue immunity; in addition, lipids participate in horm...
