Quail egg hatching rate will directly affect the utilization of new-born child's health and future performance, the following measures be taken to improve hatchability.     One egg. Eggs must be fresh, clean, saving time as short as possible to 1 week postpartum suitable, 3? 5 days for the best, more than two weeks after the hatching rate decreased, and the young quail weak constitution. Quail egg size and shape to be moderate, removing too small or too large, rough, "Sharpei egg" hard "steel egg." Quail eggs, not only the fragile eggshell thin, water evaporation inside the eggs are too fast, disruption of normal metabolism, help increase the hatching rate.     Second, incubation room. Demands good insulation, ventilation convenient, clean, quiet environment. If an ordinary electric incubator, better results. Incubating before the incubation room, the incubator should be fumigated with potassium permanganate, 5.5 grams per cubic meter, 11 tons of formalin, potassium permanganate into the ceramic dish first, and then into the formalin , immediately smoke. Quickly close the doors and windows, loose door open half an hour later the fog. This can make all the cracks, corners have been thoroughly disinfected, increase the rate and hatching rate of child health.     Third, the temperature. Quail egg incubation temperature is the most important factor, which determines fetal growth and development and productivity, the correct temperature control is a prerequisite to improve hatchability. Can use the entire batch of incubating, "the former high, Zhongping, after the low" approach for the temperature. Early (1? 6 days) temperature of 38 , the medium-term (7? 14 days) was 37.8 , the late (15? 17 days) was 37.7 . Batch hatch a "level before and after low" principle. Such as every 5 days incubating a batch, then, after the first batch of incubating with 38 , 6 days, that when the second batch of quail eggs incubating, the tune into 37.8 , several groups later incubating also take the temperature constant. After 15 days, moved to hatching device, using the conditions of 37.7 .     4, humidity. Incubator humidity should be controlled at 50? 55%, began hatching, the humidity slightly higher. Humidity can not be too high, otherwise it would quail oxygen and suffocate child. Humidity is too low, will make short hair skinny young quail, easy adhesion and broken shells and shell problems.     V, ventilation. Incubator to maintain the machine when the fresh air, the wind speed normal, vent size and location of appropriate fan rotation can not be too slow or too fast.     6, turning eggs. Hatching quail, the quail of the same batch of eggs to number the same period, quail eggs, blunt end facing upward, so that chamber to maintain the normal position, reducing the phenomenon of abnormal fetal position. Turning eggs 12 times a day, incubating 4? 5 days, 10? 12 days respectively, according to an egg, removing non-fertilized eggs and die Peidan.     7, hatching treatment. In the first 15 days of incubation, the eggs will hatch rack moved hatching machine. Increased humidity, lower temperatures, ready to hatching. Hatching period, as the hatched situation, pick out the dried shell eggs and the young quail flock to facilitate continued to hatching, hatching rate increase.
