preparation example Construction

[0023] The present invention also provides a preparation method of the above product, which includes the following steps: taking the cytokine and preparing it so that the mass concentration in the product is 1 ng / ml-1 mg / ml. In the present invention, when the ingredients of the product include an emulsifier, the preparation method further includes: emulsifying after mixing the emulsifier and the cytokine. In the present invention, the emulsification method preferably includes two-way syringe emulsification or oscillator vibration emulsification. The two-way syringe emulsification is preferably emulsified more than 200 times, more preferably 300 times; the oscillator emulsification is preferably shaken at 10000 rpm for more than 30 minutes, more preferably 30 minutes.

[0024] The method for quality inspection of the emulsion is: centrifuge the emulsion at 5000g / min for 5 minutes and pass the inspection if there is no emulsion stratification; or drop a drop of the emulsified pr...

Embodiment 1

[0029] Product composition: The cytokines are CCL2 and CCL3, both at a concentration of 100ng / ml.

[0030] Preparation:

[0031] It can be prepared according to the concentration of the above-mentioned cytokine solution, and the diluent is physiological saline.

Embodiment 2

[0033] Product composition: cytokines are CCL2 and CCL3, the concentration is 100ng / ml; emulsifier is liquid paraffin and lanolin, the mass ratio of liquid paraffin and lanolin is 2:1; the volume ratio of cytokines and emulsifier is 1: 1.

[0034] Preparation:

[0035] Mix the emulsifier and cytokine solution according to the above ratio, and emulsify 200 times with a two-way syringe. The emulsion is centrifuged at 5000g / min for 5min, and it is qualified if no emulsion stratification occurs.

Abstract

The invention belongs to the technical field of agricultural production, and particularly relates to a product for inducing antler growth of female deer, a preparation method of the product, a method for inducing antler growth of the female deer and an application. The product for inducing antler growth of the female deer comprises cell factors, the cell factors comprise a chemotactic factor CCL2 and/or a chemotactic factor CCL3, and the mass concentration of the cell factors is 1 ng/ml to 1 mg/ml. The product for inducing antler growth of the female deer is high in antler generation rate, the reproductive performance of the female deer is not affected, and the economic additional value of the female deer is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and specifically relates to a product for inducing doe antler growth, a preparation method thereof, and a method and application for inducing doe antler growth. Background technique [0002] The main source of income for the sika deer breeding industry is the sale of deer antlers, but only male sika deer produce antlers, and females do not. Studies have shown that giving exogenous androgen can induce female sika deer to grow antlers, but androgen will affect the reproductive performance of doe. Therefore, it cannot be applied to actual production. In order to further improve the economic benefits, there is an urgent need for a method that can make the doe grow antler without affecting its reproductive ability. Contents of the invention [0003] In order to solve the above problems, the present invention provides a product for inducing antler growth in doe, a preparation method...
