Embodiment 1

[0011] A gonadotropic additive for adult Portunus trituberculatus is prepared by uniformly mixing the following raw materials in parts by weight: hawthorn 10, motherwort 15, wolfberry 25, astragalus 30, and VE25.

Embodiment 2

[0013] It is basically the same as Example 1, except that the raw material formula is: hawthorn 14, motherwort 21, wolfberry 19, astragalus 24, and VE22. The above-mentioned raw materials are uniformly mixed to prepare a gonadotropic additive.

Embodiment 3

[0015] It is basically the same as Example 1, except that the raw material formula is: Hawthorn 20, Motherwort 25, Lycium barbarum 15, Astragalus 20, and VE15. The above-mentioned raw materials are uniformly mixed to prepare a gonadotropic additive.

Abstract

The invention discloses a feed additive for promoting the gonadal development of adult blue crabs and application of the feed additive. The feed additive is characterized by being prepared through uniformly mixing and compounding the following raw materials in parts by weight: 10-20 parts of haws, 15-25 parts of motherwort, 15-25 parts of Chinese wolfberry fruits, 20-30 parts of radix astragali and 15-25 parts of VE. The mass percentage of the additive for promoting the gonadal development in released feeds is 0.08-0.10%. The feed additive has the advantages that the gonadal development and the growth of the adult blue crabs can be obviously promoted, the addition quantity of the feed additive in the feeds is only 0.08-0.10%, the survival rate of the blue crabs can be increased by 6-10%, the average weight can be increased by 20.8-24.3%, the gonadal index can be increased by 15.8-17.4%, the bait coefficient is reduced by 1.93-2.1, and the color of crab cream is improved.

Description

technical field [0001] The invention relates to a feed additive for portunus trituberculatus, in particular to a gonadotropic development additive for adult crabs of portunus trituberculatus and an application thereof. Background technique [0002] Portunus trituberculatus is one of the important economic crabs in my country's coastal areas. Due to overfishing and environmental deterioration, wild fishing can no longer meet the growing market demand. Therefore, pond culture of Portunus trituberculatus has developed rapidly in coastal areas of my country. The breeding output reaches 100,000 tons. Portunus female crabs with well-developed ovaries are commonly known as cream crabs. They have the advantages of fat and tender meat, delicious taste, rich nutritional value, high edible ratio and unique flavor. The market demand is large, and the price is much higher than ordinary meat crabs (gonadal development poorer female and male crabs). As a feed additive, Chinese herbal medi...
