1. Selection of breeding eggs: breeding eggs should be produced from healthy flocks of chickens
When hatching eggs and using seed eggs, pay attention to adding various vitamins and mineral additives for poultry, and feed more protein and vitamin rich feeds, such as fish meal, bean cake and green vegetables, and pay attention to disease prevention and treatment. The ratio of cock to hen is 1:10-15 (light laying hens), and that of broiler is 1:8-10. Generally, the hatching rate of fresh eggs is the highest in 5-7 days, and the longer the storage time is, the lower the hatching rate is. Check the length of storage time, depending on the size of the air chamber. The air chamber of fresh eggs for 5-7 days is less than the size of a penny. The longer the storage time is, the bigger the air chamber will be. The eggs with sand, preserved eggs, deformed eggs, too large, too small and black spots contaminated by bacteria cannot be used for hatching.
2. Disinfection of seed eggs: Disinfection of seed eggs can improve the hatching rate and reduce the infection rate and mortality of chickens after hatching,
Now hatching advocates using bromogeramine (available in hospital pharmacies) to sterilize breeding eggs. This medicine is colorless and tasteless, does not pollute the eggshell, and has a strong sterilization rate. The amount of water washing is 1 ‰, and the amount of spray is 5%. When using this drug, it should be noted that the water temperature should not exceed 40 ℃, and the efficacy will decline if the temperature exceeds 40 ℃.
3. Indoor temperature and humidity: the room temperature should be kept at 20-25 ℃, and the relative humidity should be kept at 50-60%,
The humidification method is to sprinkle water on the ground or put a water basin on the stove.
4. Incubation in the tray: When loading the tray, the large end of the egg should be facing up, and each egg tray should be numbered. Please use the incubation record
This record is used to prevent confusion when adjusting the plate. The eggs can be served only after the temperature in the machine is stabilized at 38 ℃ for several hours. The incubation days are calculated from the egg temperature reaching 37.9 ℃ and the humidity reaching 60%, and every 24 hours is one day.
5. When the furnace is used for heating, the temperature difference can be reduced by adjusting the plate. When adjusting the plate, the temperature difference can be reduced by using a batch
Internal and external training can also be interchanged. Use a common honeycomb coal stove, place the coal stove on the side of the incubator, about 20 cm away from the side of the incubator, (the incubator should be raised or the place where the honeycomb coal stove is placed should be dug low), and connect the heater with the water pan in the incubator with a rubber tube. The interface must be firm. Add half a pan of water in the water pan. Place the heater on the mouth of the coal stove so that it can be heated with the honeycomb oven. When heating with honeycomb briquette furnace, it should be noted that the heater opening should be parallel to the bottom of the water pan. When the furnace is used for heating, the upper opening of the water pan in the machine shall be covered with a layer of plastic film, which shall be fixed with paper clips to prevent excessive humidity. Temperature insulation layer shall be placed on the water pan to prevent the two plates of eggs close to the water pan from overheating. An incubation thermometer or thermometer should be placed on the egg tray on the top and bottom of the egg tray rack to observe and adjust the temperature at any time. The water level in the water pan should be kept at a height of 5cm, and the water should be checked frequently. Never cut off the water. If the furnace is not hot, and the power is cut off, the temperature in the machine is low, the prepared boiled water can be poured into the water pan from the external water pipe to improve the temperature.
6. Electrothermal thawing: check all parts of the incubator (especially the egg turner and the egg turner, the water pan must be
Add more than half of the water. Do not connect the power supply directly without adding water, which will burn the heating parts in the water pan.) Only after it is normal can it be connected to the 220V power supply for power-on and trial use. In case of any abnormality, cut off the power supply immediately and find out the cause. The incubator is automatically controlled by microcomputer. The program and data in the controller have been set according to the incubation requirements, and ordinary users do not need to adjust. If you need to adjust, you should read the instrument manual before debugging. The temperature and humidity probe sensor on the instrument should be protected.
7. Use of ventilation holes: When using the incubator for the first time, all parts should be closed tightly, and the ventilation holes on the incubator should be complete
After seven days of incubation, we should watch the weather gradually open.
