1. Preparation before hatching To avoid malfunction during the hatching period. Therefore, before hatching, conduct a comprehensive overhaul to check the accuracy of temperature regulators and thermometers; whether motors, fans, electric heaters, indicator lights and alarm devices are sensitive, whether the doors, walls and floors of the incubator are tight, egg trays and Check whether the hatching tray is firm, etc. Have your generator ready in case of a power outage.
The incubator is sterilized and the test machine is normal for 24 hours before the eggs can be hatched. The eggs from the egg storage are placed in the incubation room at about 22 degrees Celsius to pre-warm for 4-6 hours, and the eggs are placed on a tray with the big end up for incubation and disinfection.
2. Incubator management Modern three-dimensional incubators have a high degree of mechanization and automation. Therefore, the management is relatively simple, but the hatching volume is large. Once an accident occurs, it will cause great economic losses. Managers must carefully do the following: Item management work:
(1) Adjustment of temperature Pay attention to the change of temperature, observe the sensitivity of the regulator, and whether the change of the indicator light of the thermometer is consistent. If the temperature adjustment performance is stable, do not twist it easily after the temperature adjustment, unless it deviates from the temperature by ±0.5 degrees Celsius, it should be adjusted immediately. Temperatures are generally recorded every hour.
(2) Humidity adjustment Modern three-dimensional incubators have automatic humidity adjustment equipment. There is no automatic humidity adjustment incubator. There is a water tray inside. Water should be added to the water tray regularly every day. plate or adjust the water temperature. The wet bulb water cup should be filled with water frequently, and the cotton string should be cleaned and replaced regularly to ensure the accuracy of the wet bulb.

(3) Fans and egg racks for ventilation, egg turning and other management incubators should be kept clean and dust-free so as not to affect the ventilation in the incubator. The three-dimensional incubator can regularly turn the eggs at a fixed angle, generally once every 1-3 hours. When shaking the egg by hand, it should be light, steady and slow to avoid malfunction. The motor should be refueled regularly, pay attention to whether the operation of the parts is normal and whether there is any abnormal sound. Do a good job of recording the temperature, humidity and room temperature every day.
(4) According to the eggs, the eggs are checked regularly to check the development of the embryos. The operation of the eggs should be light, fast, and quasi-action should be careful and steady to prevent shocks and damage to the embryos. Observe carefully to avoid missing and wrong photos.
(5) Egg transfer (disc) The transfer of embryonated eggs from the hatching tray to the hatching tray is generally called egg transfer and tray transfer (disc). Chicken embryos are moved to the hatching tray on the 18th to 19th day of incubation. The age of the egg transfer depends on the development of the embryo and egg. If the embryo development is delayed, the transfer of the egg can be delayed for 12-24 hours. When eggs are transferred to the hatcher tray, lay flat and stop turning the eggs.
(6) Hatching The chick embryos start hatching in 20 days, and the light of the hatcher is turned off to prevent the chicks from disturbing and affecting the hatching. 3-4 hours after the start of hatching, when the chick feathers are dry, the chicks can be picked, and the empty eggshells can be picked out at the same time.
(7) After cleaning and hatching, remove the hatching tray, hatching tray, water tray, brush off broken eggshells, dirt and fluff, rinse and dry, then fumigate or use disinfectant for disinfection. spare.
Adhere to the daily maintenance of the incubator in order to maintain the normal hatching work of poultry.
