3, generally go into to incubate first all per 2 hours egg-turnings once, later every day 4-6 time, after the embryo egg goes to chick box by incubation plate, stop the egg-turning operation.
4, the egg inspection was carried out in the hatching back from 7-8 days, promptly passed through sunshine or light according to egg, selected the wind egg and the addled egg of the inner no trace of blood, carried out the egg inspection second time in 14-16 days, and egg is examined for the second time, selects the bad egg of muddy stain in lighter color, the egg.
5, goose hatching to two photograph (15-16 embryo age) just begins cool egg; Whenever round the clock 2-3 time, guarantee every day at upper and lower noon each 1 time, each 20 ~ 40 minutes; Egg temperature drop to 32.2 ℃ (90 ° of F) is got final product, or eyelid sensing egg temperature is felt little slightly and is put into machine when cool and continue hatching.
Get final product hatching about 6, hatching, hatching of breeding eggs to 25 day, the hatching chamber temperature is set at 36 ℃, and humidity is set at 70 ~ 75%.
Kind of egg adopts alternating temperature hatching system when hatching, incubation temperature should grasp " preceding height, in flat, the back is low " principle, and excursion is in 37.8-37.6 ℃ the scope.Keep a close eye on the regulation and control of temperature simultaneously, prevent to cause local embryo to cause the mortality accident.The wet and dry bulb meter is used in its moisture measurement, and the water in the wet and dry bulb meter tank should be put into clean water.Mercury ball is outer should wrap up in meche.Put into hatching house's certain position to psychrometer then, after a period of time, deduct the reading of wet-bulb thermometer,, look into the relative moisture shown in the two difference then according to the temperature difference shown in the wet-and-dry-bulb thermometer with the reading of dry bulb thermometer.
Simultaneously, plant egg and when hatching, answer traverse (keeping flat), to cooperate the wide-angle of goose egg egg-turning, can increase goose embryo's scope of activities, the blood vessel network system distributes more extensively more fully, helps the raising of embryonic life power and incubation rate.The egg-turning angle should be 120 degree (± 60 degree) to reducing the dead germ rate, and it is extremely beneficial with strong young rate to improve incubation rate.
In the present invention, in cool egg process, suitable warm water can make the calcium carbonate in the eggshell become calcium bicarbonate and become fragile, and helps broken shell, also can prevent egg shell membrane and protein film overdrying, causes young fowl fetal hair and its generation adhesive hair phenomenon.
In the present invention, the conventional method of cool egg has: 1. power cutoff, open the cool egg of door air blast; Open gate when 2. it is warm, release the cool egg of egg unwheeling; Can spray warm water pearl (25-30 ℃) on eggshell when 3. it is warm, to accelerate temperature-fall period.Will combine room temperature to grasp flexibly during the cold egg, cool egg must be done in the proper way, otherwise not just can not cause young fowl fetal hair look, and broken shell does not go out, or hatching is uneven, and cool egg is of a specified duration excessively, causes a mao tire to increase, and particularly when absorbing sharp end thick white, it is of a specified duration excessively to be sure not cool egg.
