Problems solved by technology

However, the molting process is a consumption process. During the molting process, animals will stop eating and consume more materials and energy to synthesize new shells. Therefore, one-sided use of molting hormones or improper use will cause excessive energy consumption of prawns. not conducive to growth
[0011] Among the existing main crustacean growth promoters, most of them are mixed into the feed in the form of feed additives, and the process requirements and costs are relatively high

Embodiment 1

[0025] Example 1: The synthesis method of KK-42, the basic principle is that citral and benzylamine react, and evaporate under reduced pressure to obtain imine.

[0026] (1) 3.2g of benzylamine, 4.5g of citral (gas-liquid chromatography analysis of its Z:E configuration=7:3), 15g of anhydrous MgSO 4 , 30ml of CH 2 Cl 2 Mix and stir at reflux for 3h. Filter out MgSO under reduced pressure 4filter cake and concentrate the remaining solvent. Add 30ml of anhydrous methanol, 15g of anhydrous potassium carbonate, and 7.5g of tosylmethylisocyanide (TosMIC) (Ningbo Sailun Chemical Co., Ltd.) to the residue in the flask, stir to dissolve and repeat reflux for 3h, The response is complete. Afterwards, the reflux device was changed to a distillation device to remove most of the methanol, and then extracted with ether, and the organic phase was washed with water and saturated brine respectively. After drying and filtering over sodium sulfate, the product was spin-dried to obtain a w...

Abstract

The invention discloses a growth promoting additive for crustacean breeding. A component, which is anti-juvenile hormone KK-42, is synthesized by reacting two compounds namely aldimine and p-tolylsulfonylmethyl isocyanide (TosMIC) in the presence of potassium carbonate, and performing silica-gel column chromatography on a coarse product by an eluent for separation, and dissolving and diluting by using acetone to prepare a 0.01wt% anti-juvenile hormone aqueous solution; weighing 1-3 parts of the anti-juvenile hormone aqueous solution, 20-80 parts of an ecdysone raw material, 500-1,000 parts of a vitamin C raw material, 4,500-7,000 parts of a glucose raw material and 2,138-4,477 parts of a zeolite powder raw material according to the weight proportion to be added into a mixing machine to be mixed for 5-10 minutes until the uniformity is 5 percent to obtain a mixture; and packaging the mixture. According to the growth promoting additive, the stress resistance of shrimps and crabs can be improved, the feed utilization rate is increased, and the deshelling and growth of the shrimps and the crabs are promoted.

Description

technical field [0001] The invention relates to the technical field of crustacean breeding and growth promotion, in particular to technologies such as the artificial synthesis of crustacean exogenous hormones and the combination of two hormones and nutrients as novel crustacean growth-promoting agents. Background technique [0002] Shrimp and crab molting is a very important physiological phenomenon in their life process. It is not only related to the growth of shrimp and crab, but also related to the change of shape, the regeneration of severed limbs, and mating and other activities. When young, the shell is thin and soft, called the skin. The larvae molt mainly undergo metamorphosis, so they are called developmental molts. After entering the juvenile shrimp or juvenile crab stage, moulting is a sign of growth, which is called growth moulting. There are also many females of shrimps and crabs that need to moult before mating. This moulting is related to copulation and repr...
