First, the selection of seed pods The seed pods should be selected within three generations, well-developed, disease-free, with a body weight of 120 grams or more and full-bodied. The red ball of the male anus is fine and bright red; the mother’s abdominal volume is large, the pubis free end and the back of the sternum are three fingers wide, the left and right pubic bones are two fingers wide, and the male and female species are in a ratio of 1:3. Cage rearing, natural mating.
Second, the hatching selection output within a week of obvious spots, moderate size, egg-shaped normal egg disinfection, according to the blunt head up at 25 °C indoor preheat 6 to 8 hours after hatching. Incubation management is as follows.
1. The temperature of quail eggs during the incubation process should implement the "pre-high, mid-term, late low" principle, combined with the incubation season, outside temperature, embryonic development of flexible grasp "see fetal temperature," generally maintained at 38 °C ~ Between 39°C.
2. Relative Humidity The relative humidity in the incubator is maintained at 60% to 65%. Humidity can be increased to 80% the day before hatching.
3. Ventilation and ventilation The requirements for oxygen in embryos are less in the early stage, more in the later stage, less in winter and more in summer. In the first 8 days of incubation, ventilation should be opened at regular intervals, and ventilation should be repeated frequently for 8 days.
4. When the egg is transferred from the hatching of the egg to the beginning of the hatching 2 to 3 days before the hatching, the egg is turned 4 to 12 times per day and night.
5. cool eggs open the incubator door, reduce the egg temperature, cool eggs each time with the specific circumstances of flexible control, with the eyelid test temperature can feel cool.
6. As soon as the egg is examined, 5 to 7 days after hatching, the lean and dead embryos are eliminated. The second shot is performed within 12 to 13 days after hatching, and the dead eggs are eliminated.
7. Hatching Incubate at 15 days and place the eggs. Remove the eggs from the egg tray and place them in the hatching tray. Increase the humidity of the incubator to 80% until the hatching. The newborn hair can be removed after drying.
