Problems solved by technology

[0002] In the breeding process of portunus trituberculatus, low-value small miscellaneous fish and shellfish are often used for direct feeding. Not only is the contradiction between supply and demand of fresh bait increasingly prominent, but it is also very easy to cause environmental pollution in the breeding waters and frequent occurrence of diseases.
At present, there is no published compound feed about promoting the ovarian development and yolk production of Portunus trituberculatus at this stage.

Abstract

The invention discloses mixed feed for promoting portunus trituberculatus ovarian development and vitellogenesis and a preparation method of the mixed feed. The mixed feed is characterized in that the mixed feed is prepared by mixing the following raw materials in parts by weight: 25 to 30 parts of fish meal, 20 to 25 parts of soybean meal, 5 to 10 parts of krill meal, 20 to 25 parts of squid viscera meal, 15 to 20 parts of flour, 3 to 5 parts of soya bean lecithin, 1 to 2 parts of fish oil, 0.3 to 0.5 parts of cholesterol, 0.3 to 0.5 parts of choline chloride, 1.5 to 2.5 parts of sodium alginate, 0.5 to 1.0 part of composite additive, 0.5 to 1.0 parts of vitamin mixture, 1.0 to 1.5 parts of mineral substance mixture, 1.0 to 1.5 parts of monocalcium phosphate and 25 to 30 parts of water, the mixed feed has the advantages that the survival rate of portunus trituberculatus is improved by 18 to 22 percent, the gonad index can be improved by 34 to 40 percent, the content of vitellogenin can be improved by 36 to 46 percent, and the molecule expression quantity of the vitellogenin can be improved by 60 to 80 percent.

Description

technical field [0001] The invention relates to a compound feed for portunus trituberculatus, in particular to a compound feed for promoting ovarian development and yolk generation of portunus trituberculatus. Background technique [0002] In the breeding process of portunus trituberculatus, low-value small miscellaneous fish and shellfish are often used for direct feeding. Not only the contradiction between supply and demand of fresh bait is becoming increasingly prominent, but also it is very easy to cause environmental pollution of breeding waters and frequent occurrence of diseases. What is more prominent is that the cultured portunus trituberculatus has poor ovarian development, the color of the crab paste is obviously light (or not red), the muscle and crab paste are poor in plumpness and other quality problems, as well as the number of eggs and the development of offspring are poor. And so on. Vitellogenesis refers to the formation of various proteins, lipids, carboh...
