Abstract

The invention discloses application of a compound feed additive in preparation of feed for improving muscle texture of cultured large yellow croakers. Glycerol monolaurate, glycerol caprate and glycerol caprylate are used as feed additives and are added into the feed for culturing the large yellow croakers according to a ratio. According to the application disclosed by the invention, medium-chainfatty acid is applied through the feed additive, so that the mRNA level synthesized by muscle fibers in bodies of the cultured large yellow croakers can be effectively improved, and a metabolic pathway synthesized by protein and amino acid is up-regulated, and furthermore, the muscle texture and muscle fiber diameter of the large yellow croakers are improved. According to the application disclosedby the invention, the medium-chain fatty acid is applied through the feed additive, so that the content level of the amino acid, fatty acid and flavor substances in the muscles of the cultured largeyellow croakers can also be effectively improved, and furthermore, the flavor substances of the large yellow croakers are improved.

Description

technical field

[0001] The application relates to the technical field of aquaculture, in particular to the application of a compound feed additive in the preparation of feed for aquaculture large yellow croaker. Background technique

[0002] Medium-chain fatty acids (MCFAs) are saturated fatty acids with a carbon chain length of 8-12, including caprylic acid (C8:0), capric acid (C10:0) and lauric acid (C12:0), which are naturally present in animal milk fat and Coconut oil and palm kernel oil are fatty acids that are abundant in nature, easy to obtain, and easy to use. Medium-chain fatty acid monoglycerides have special chemical and physical properties. Compared with long-chain fatty acids, they have a lower melting point and are easier to dissolve; in animals, they can be directly transported to the liver for metabolism through the portal vein blood flow, achieving rapid supply. In addition, medium-chain fatty acid monoglycerides also have high-efficiency, broad-spectrum an...
