Embodiment 1

[0015] Eggs are used for hatching. Take 100 breeding eggs of self-distinguishing male and female chickens (the sex can be distinguished from the color of the feathers when the chicks hatch), and they are used for incubation. First, use 0.1% bromogeramine to spray or wipe for disinfection. After drying, put the eggs into a sealed pressure vessel and immerse them in a mixture of methyltestosterone (if it is solid powder or tablet, first dissolved in an organic solvent) and distilled water or saline. In the solution, the concentration of the solution is 5mol. Close the container, pressurize to 3 atmospheres, and keep it for 1 hour. Take out the eggs and wait for them to dry before hatching. After hatching, the male and female of the chicken can be distinguished from the color of the feathers.

Embodiment 2

[0017] Use goose eggs as eggs for incubation. Get 100 goose eggs for hatching. First, use 0.1% bromogeramine to spray or wipe for disinfection. After drying, put the eggs into a sealed pressure vessel and immerse them in a mixture of methyltestosterone (if it is solid powder or tablet, first dissolved in an organic solvent) and distilled water or saline. In the solution, the concentration of the solution is 15mol, the container is closed, pressurized to 3 atmospheres, and kept for 1 hour, the eggs are taken out and allowed to enter artificial incubation after drying.

Embodiment 3

[0019] Hatching is carried out with soft-shelled turtle eggs as breeding eggs. Get 100 soft-shelled turtle eggs for hatching. First, use 0.1% bromogeramine to spray or wipe for disinfection. After drying, put the eggs into a sealed pressure vessel and immerse them in a solution prepared with testosterone propionate (if it is a solid powder or tablet, first dissolved in an organic solvent) and distilled water or normal saline. In the mixed solution, the concentration of the solution is 3mol, the container is closed, pressurized to 2 atmospheres, and kept for 45 minutes, the eggs are taken out and allowed to enter artificial incubation after drying.

Abstract

A method and a device for improving male hatching rate of oviparity mainly solve the drawback that the male hatching rate of the current artificial incubation of the oviparity is low. The method comprises the following steps: arranging the hatching eggs after disinfected in a sealed pressure container before the artificial incubation; dipping the hatching eggs in the mixed liquid formed by mixing made drugs analogous with distilled water or normal saline; sealing the container, pressurizing to 2-3 atmospheric pressure, and keeping for 0.5 to 1 hour; taking the hatching eggs outside, then drying and entering the artificial incubation. The invention has a simple technology, little investment, good efficiency, high male hatching rate which reaches 65% to 80%, and can be widely applied to the artificial breeding of the oviparity, such as poultry, rare birds, snakes, tortoise and trionyx sinensis.

Description

technical field [0001] The invention belongs to the technical field of artificial hatching of oviparous animals, and in particular relates to a method and a device for improving the male hatching rate of oviparous animals. Background technique [0002] There are two genes in the undeveloped stage of the embryo, one is the cortex, which develops into an ovary, and the other is the bone spine, which develops into a testis. These two genes can develop into females or males under the same external conditions. The acting factor is the weak and strong sex hormones. The two genes that exist in the undeveloped stage of the egg embryo develop under natural conditions. If the estrogen in the egg is strong, the cortex will develop vigorously, form an ovary, and then develop into a female. If the androgen in the egg is strong, the bone spine will develop. The quality develops vigorously, forming testicles, and then develops into a male. Therefore, before the eggs are not developed, ar...
