Biogas hatching has the advantages of simple operation, safety, high hatching rate, low cost, etc. It is very suitable for small-scale (less than 1000) farmers. 1 cubic meter of biogas can incubate 475 eggs. The biogas incubator consumes 30-40 liters of gas per hour. The hatching rate of fertilized eggs is over 90%. The hatching rate of biogas is 5%-15% higher than the rate of electricity and oil hatching, and the saving rate is 12.5 kwh/100 eggs per incubation, or 3 kg of fuel can be saved.
Preparation before hatch
1. Well-built hatching room: The hatching room should be ventilated, sunny, warm, moderate and wide, and easy to operate. To clean and disinfect with quicklime. Existing housing can also be used instead. Incubation room temperature should be increased to 20 °C -24 °C.
2. Making incubator box: The incubator box is made of wood or fiberboard. The dimensions of the empty space are 60 centimeters, 60 centimeters and 110 centimeters in length, width and height. Made of sandwich, sandwich filled with wood chips and other insulation materials. Doors need to be flat, sealed, and flexible to open. The insulation measures are the same as those of the cabinet. Can also be made into a single layer, wrapped with old cotton wool and other insulation materials. Inside the box, press 18 cm to make a 6-layer egg tray. The egg tray is made of wood and the iron net is nailed at the bottom. It can also be made of iron wire. It is advisable that the mesh is not leaky. Each of the upper, middle, and lower parts of the box is worn with a small eye and three thermometers are inserted.
3, hatching stove: built biogas stoves, stoves to be smooth, solid and safe, configure a diameter of 57 cm iron pot, the cooker under the biogas stove, gas pipeline to be standardized, reasonable, flexible switch, closed.
Incubation management
1, egg treatment: Select fresh, smooth shell surface, uniform size, oval-shaped clean eggs, washed, placed in 35 °C -40 °C 0.1% potassium permanganate solution immersed in disinfection for 10 minutes.
2. Plate: Drain the sterilized eggs and place them in trays. Half a day advance into the 20 °C -24 °C incubator preheating, and then into the incubator, pay attention to the chassis without egg.
3, warming: ignite biogas furnace, burning pot, pan temperature rise, increase the temperature of the incubator. After warming, the incubator should be monitored and managed for 24 hours, and the tank temperature should be controlled as follows: early (1-10 days) 38.5°C-39.5°C; medium (11-16 days) 38°C-38.5°C; late (17) -21 days) 37°C - 38°C.
4, adjust the plate turn the eggs: When entering the incubator, the box temperature is the next high and low, so it should be turned every 4-6 hours 1 egg, the method is to swap the plates up and down, before and after the change of each egg position. By turning the plate, the eggs are subjected to the same temperature and the shells are uniform.
5, to master the humidity: Incubation humidity should be controlled in: about 60% in the early stage, about 55% in the middle stage, about 70% in the latter stage. When chicks hatch out, they must pay strict attention to temperature and humidity. If the humidity is not enough, increase the water tray at the bottom of the box.
6, according to the egg: Incubation must be according to the egg 3 times: the first time (day 5-6), can clearly see the eye, cried. At this time, the extent of blood vessel distribution has been quite large, indicating normal development. On the second (days 10-11), the blood vessels were seen distributed throughout the egg and closed at the small head, indicating normal temperature. The third time in the first hatching day. At this time, the eggs are out of the air and they are all black. This is called closing the door.
Precautions
1. From the ignition to the 13th day (or 14th day), the biogas stove must be continuously burned without interruption. If biogas is insufficient, it must be supplemented with other energy sources.
2. After hatching, the chicks should be kept at a constant temperature of 32°C for 3 days in order to enhance the resilience of chicks and increase the survival rate.
