The winter and spring season is a good season for hatching geese and geese. As the goose eggshell is hard and big, the artificial hatching rate is low. The use of bionic incubator thermostat technology effectively improved the breeding rate of goose eggs and the rate of hatching.
Composition of bionic hatchery incubator
Bionic hatchery warm box is composed of vertical hatch box and flat hatching box.
The vertical incubator was made of uniform stainless steel plates, and made into a cylindrical inner cylinder with a diameter of 40-55 cm and a height of 50-55 cm, plus an outer cylinder. The inner and outer cylinders are 6-8 cm apart and form a sandwich cylinder. The bottom is equipped with a drain pipe with a diameter of 2-5 cm leading to the middle layer. Install a 0.5 cm diameter exhaust pipe along the box. A vent pipe with a diameter of 2 cm and a length of 5 cm is installed at the bottom and middle of the thermostat, and an overflow pipe with a diameter of 0.5 cm and a length of 5 cm is installed along the outer wall of the enclosure. There is a heat storage layer inside the box. The outer wall of the box has a thermal insulation material as a protective layer. The egg tray is round sieve-shaped. The diameter of the egg tray is selected according to the size of the box. The plate is 8-10 cm high, supported by a wooden frame and has 6 layers of egg trays. The quilt at the bottom of the vertical incubator lid is kept warm and the edge of the lid is 10 cm high. The center of the lid is drilled with three small circular holes in the triangle, which can check the temperature of the eggs and also adjust the temperature.
The flat hatching box is made of stainless steel plate or light metal plate and is made of 150 cm in length, 80 cm in width and 28 cm in height. The distance between the top and bottom is 6 cm. The distance between the outer wall and the inner wall is 3 cm bunk bed tank. Inside the box, two lengths and widths are suitable for each layer, and a total of eight egg trays with a height of 6 cm are prepared. At the same time, sawdust insulation materials and gauze, single cloths, quilts and the like covering the temperature of the egg are prepared.
In the early stage of hatching, the goose eggs are incubated at a low temperature, and the eggs are hatched in a vertical box. The characteristics of uniform heat supply at the bottom of the vertical box and the surrounding storage heat are used to uniformly heat the various parts of the goose eggs; after incubation to 17 days The temperature of embryos and eggs gradually increases. At this time, the goose eggs should be transferred from the vertical box to the flat hatching box. By adding hot and cold water to the flat hatching box, the temperature of the egg can be accurately adjusted within the required range; by raising, lowering, thickening, thinning, or opening the cover of the incubator, the mid and late stages are adjusted until the eggs are hatched. The need for oxygen supply, cool eggs, and humidification make it in a state of imitation of natural hatching. Not only does it significantly increase the hatching rate of goose eggs, but it also enhances the adaptability of goslings to the natural environment.
Temperature and humidity control
Temperature Due to the special structure of the shell membrane, egg shell, stomata and inner shell membrane of the goose, the hatching eggs are slow to heat during the early stage of incubation, and the lipid content is relatively high. In addition, a large amount of physiological heat is generated in the middle and later stages, making it difficult to dissipate heat. Therefore, in the incubation process, the principle of Schwarm is: pre-heating eggs before hatching at 36 °C -38 °C, preheat 5-8 hours, early in the incubation period is high, mid-term flat, later slightly lower, slightly higher hatching period .
The principle of humidity control humidity: before and after the high, the middle level. Pre-humidity is high, so that the eggs can be heated well and evenly; medium-term level is conducive to the embryo's metabolism; to the late stage and the hatching stage, the purpose of raising the humidity is to dissipate too much physiological heat, so that the eggshell structure is loose, so that the shell Chubby. In practice, the temperature and humidity must be adjusted in conjunction with cool eggs and water spray, and the effects of seasonal placement and other environmental factors on the matching placement of the bionic vertical hatching box and the flat hatching hatching should be considered.
Eggs and water spray
Eggs are generally not cooled in the early stage of hatching. According to the above-mentioned Schwenn program, the egg temperature in the middle and later stages can reach 38.8°C. The surface area of ​​the shell is relatively small, the pores are small, and the heat dissipation is slow. If too much physiological heat is not promptly emitted, it may cause the embryos to be suffocated in the eggs. Continuing eggs can enhance the gas exchange of the embryos and eliminate the build-up of heat in the eggs. Eggs are dried 2-4 times a day, and the length of time for egg drying varies, depending on the situation.
Water spray is currently considered to be the key to improving the hatching rate of goose eggs. The presence of the membrane on the shell is beneficial to the hatching head for several days. As the embryonic age continues to increase, especially when the allantoic membrane is closed and needs to absorb more oxygen and excrete a large amount of metabolites, it begins to Development has a bad shadow. To get rid of it, it is necessary to spray eggs that have hatched for 21-32 days. Spray once a day and spray the eggs until they are soaked. Allow to dry before hatching. Embryo eggs in the repeated cold eggs, water spray and the role of carbon dioxide in the air, the eggshell calcium carbonate into calcium bicarbonate, its nature from hard to crisp, goslings are easy to shell, can reduce the stillborn period of stillbirth .
