1. Sterilize the eggs in time.
Seed eggs can be stored at room temperature of 13 ~ 15℃ for up to 5 ~ 7 days. Before hatching, it should be soaked in 0.02% potassium permanganate solution for 2 minutes, dried and hatched.
2. Control temperature and humidity.
After hatching 1 ~ 18 days, the suitable temperature is 37.8 ~ 38.0℃ in winter and 37.5℃ in summer. 19, and the suitable temperature is 37.2℃ in winter and 37.0℃ in summer. The relative humidity requirement is that 1 to 18 is 60%, and 19 to 2 1 is 70%. The way to increase humidity is to add a water tray or wet towel organically and spray warm water on the surface of eggs.
3. Turn eggs and take photos.
On day 1 ~ 18, turn eggs every 2 ~ 4 hours 1 time. Sperm eggs and dead embryo eggs were picked out on the 5th to 7th day, and live embryo eggs were transferred to the incubator on the 9th day/kloc-0, and the eggs were turned over for hatching. During dystocia, the eggshell can be gently peeled off by artificial midwifery.
