The temperature of the goose and eggs on the spreading bed should be kept at about 36.5°C. The roof of the hatchery room should have a heat insulation layer, and the doors and windows should have dustproof, waterproof, windproof devices and ventilation holes. The size of the bed depends on the size of the hatchery, and is usually two stories above and below. It is generally 1.5 to 1.8 meters high and 2 meters wide. Each bed is about 0.8 meters high. The bed, paper pad, chaff, straw mat, and paper Such as composition, the middle position of the bed is slightly higher than the surrounding, surrounded by four sides about 15 cm, spread out the bed with blankets, mosquito net cloth and other coverings, for different climate conditions to use. The temperature of the hatching room should be controlled at 20 ~ 28 °C, relative humidity 65% ​​~ 70%, close the doors and windows, open the vent hole in cold weather.
It is better to have the time spent on the stalls at noon. Half an hour before the stall, the temperature of the incubator should be increased to about 38 °C, and then shut down. The eggs must be checked first, and the dead embryos should be detected. After the eggs are transferred, the goose eggs are moved to the stall, the flats are laid, and the eggs are then pressed. The development status and size of the corresponding adjustment position. Slowly growing big goose eggs are placed in the middle, and the fast-growing eggs are arranged around.
After maintaining the normal temperature and humidity of the goose eggs, the edges of the spreading bed were surrounded with slivers to strictly surround all the eggs. Then spray the first time water (water temperature is 36 ~ 40 °C), the water to spray evenly, the right amount can not have "sweat." After spraying the water, cover three layers of mosquito net cloth and add another layer of sheets. The amount of cover should vary depending on weather conditions and the environment of the incubator. Outside the hanging bed is covered with a blanket. Pay close attention to the changes in the egg temperature and avoid overgrowth of goslings.
“Scalding†should be carried out 6 times a day for 4 hours at a time in order to maintain a uniform temperature across the surface of the bed. Open the cover first, spread the hands to an obtuse angle, push the goose egg at the edge of the bed towards the middle, and push the original goose egg in the middle to the edge. Every time the goose egg is changed, spray water once, and the water spray should be misty. The method is the same as when the stall is spread, and then cover the quilt until the temperature of the egg rises to the normal incubation temperature. At this time, the egg temperature can be evenly distributed. Grab the number of layers covering the quilts in time after the rush.
Timely removal of dead embryonic eggs With the increase in the age of the embryo, hatched eggs can be reduced accordingly. Before the shell is hatched, the “flashing†embryos are pulled out and put together so as to be hatched. Every time a dead embryo egg is seen during hatching, it must be immediately removed.
