To maintain a good pheasant, hatching and brooding is the key to success or failure. 1, choose eggs. Eggs must meet the requirements of the breed, the size of the eggs is moderate, the shape of the eggs is normal (elliptical) and the color is bright, preferably not more than 10 days. 2, egg disinfection. Egg-type disinfectants are quite extensive, but most of them can only act on pathogenic bacteria on the surface of eggshells, and we use antibiotic liquids to soak eggs, not only to kill bacteria on the surface of eggs, but also to kill egg whites and typhoids in eggs. Diseases such as paratyphoid, E. coli, and other pathogens far exceed other methods. The preparation method is to add 25 kg of warm water at 30° C. into the water basin, and then put 800,000 units of penicillin 8 bottles, 1 million units of 15 bottles of leucomycin dissolved in water, and then put the eggs into the water for 2 to 3 minutes and then take out the air. Dry hatching can improve hatching rate, survival rate and survival rate. 3, temperature control. According to the development of the embryos, temperature control methods should be adopted, which are high in the early stage, moderate in the middle stage, slightly lower in the later stage, and slightly higher in the larvae. The eggs are placed in the hatchery after preheating the eggs before hatching. Egg temperature was controlled between 37°C and 38°C, controlled at 38.8°C for 7 days after incubation, 38°C-38.5°C for 15-20 days, and 38.5°C-39°C for 21-24 days. 4, turn the egg. Turning eggs can make embryonic development movements, replacement locations, even heating and promote metabolism. Eggs are sterilized and immersed before hatching. Its moisture is high. In order to raise the egg temperature to make the surface evenly heated and the egg surface water droplets condense, one should turn the egg 3-4 times on the first day, then turn it once every 8 hours, turn the egg angle 180 degrees until 20-24 days. Stop turning eggs. 5, according to the egg. Usually 3 times, 3 days after hatching, the first shot is taken. Timely detection of zygote, dead zygotic, lean egg transparent only in the middle 1 small black spots or clear light, and can see a lot of trachoma, dead sperm without bloodshot. On the 11th day of the second time, the eggs were normally half black and the embryos were incomplete. On the 19th day of the third day, the normal development of live embryos, the convergence of blood vessels in the head of the egg, the flickering of dark shadows in the air chamber, the visible air chamber of the dead embryo, and the development of residual blood vessels and dead embryos on the two lower parts of the egg. shadow. 6, humidity. It is better to control the humidity in the middle of the incubation period between the two ends. The relative humidity in the early stage is 60%-65%, the middle is 55%-60%, and the latter stage is 65%-68%. It should be noted that 70%-75% should be taken when the baby is hatched, because the low humidity at the later stage will affect the quality of the hatching. 7, egg. Eggs are mainly used to help the embryos disperse the excess heat in order to reduce the egg temperature in a short period of time to adapt to the development of the embryo, especially in the mid-and late embryos increase day by day, the metabolism of the body to strengthen, resulting in a large number of biological heat, at this time The heat can be sufficient to supply embryonic development, and there is excess heat, so that the mat will not be released to affect the embryonic development. Incubation begins 12 days after the beginning of the egg, egg temperature suitable for the height of the egg temperature and flexible control, the general eyelid test temperature is more accurate, because the incubation temperature is similar to human body temperature, as long as the eggs to the eyelid by feeling hot and can continue to hatch . 8, spray water. Water spray is one of the key measures to increase the hatching rate. Incubate 21-24 days of embryo eggs should be sprayed, the water temperature between 35 °C -38 °C, spray water is to promote eggshell calcification, chicks easy to shell, hatching neatly reduce hatchlings, appropriate conditions and general daily spray Water 1-2 times, hatching generally in 23-24 days all out.
