There are two kinds of hatching methods for chickens: one is natural hatching and the other is artificial hatching.
1. Natural Incubation Method (Bag Wo Chicken Incubation Method)
The natural incubation method, also known as the brooding chicken hatching method, is the simplest and most economical hatching method that is commonly used by farmers. In the incubation process, special care is not required and the hatching rate is also high. After chicks are hatched, they are led by hens and managed easily. However, this method also has a small amount of hatching, buns, seasonal restrictions and influence.
2. Artificial hatching
1 Preparation for artificial hatching. Artificial incubation must first prepare the electric incubator. The automatic electric incubator has an automatic temperature control and humidity control system, which can automatically turn eggs, ventilation, and water. Before hatching, it needs to be pre-heated, disinfected, hatched, sterilized and inspected. incubation.
2 eggs tested and preheated. The incubator was preheated for 4 to 6 hours. The incubator was heated to 39°C and the humidity reached the desired level. After everything is normal, the eggs can be hatched.
3 yards. It is to arrange the eggs in an orderly manner in the hatching tray (large head on top, small head down).
4 Incubation management. a. Control humidity and temperature. When the eggs are incubated for 1 to 19 days, the temperature should be 37.5°C to 37.8°C; for 20 to 21 days, it should be 37.3°C to 37.0°C. In the first week of incubation, the relative humidity was about 65%, and then it was reduced to 55%. After 19 days, it increased to 70% to 75%. b. Turn eggs, transfer plates and hatching. Turning eggs is also called turning eggs. Turning the eggs 6-8 times a day, turn the eggs on the 19th day. At this time, the eggs are removed from the incubator and moved out of the hatching machine (moving the egg tray). This process is called transfer, also known as landing. When the hatching progressed to about 21 days, the chicks were hatched in large numbers and called hatching.
Note that you can't turn the egg after moving it, so as to avoid dizziness and hard shelling.
5 according to the egg. In the hatching of eggs, eggs are used to determine whether the eggs are fertilized, whether the embryos are normal, and whether they died in the middle.
Tools and materials can be used as portable electric lights or special egg feeders.
Steps: a. Wash, disinfect and dry the wood box. b. Install wires, lamp holders, and install the incandescent lamp on the bottom of the wood box and put it into the dark room. c. Open the lamp in the wood box. d. Sandwich the eggs to be photographed between the thumb and forefinger of the right hand, with the big head on top, and place it in a small hole in the plate box to rotate the perspective and observe the development of the embryo. e. Each egg was incubated 5 to 6 days, 11 to 12 days, and 18 to 19 days after hatching.
Many people always love to use mocking tone to say other people: "You have neuropathy." in real life, It is essentially different with medical psychosis. First of all, it is clear that mental illness is a mental incapacity, behavioral abnormalities as the main features of the disease, regardless of any approach, mental patients have no civil capacity, but also can not be founding, more and more studies show that psychosis is from the pre-born which is a neurological disease caused by a genetic factor (gene) that has changed. The treatment of psychosis mainly take drug, behavioral therapy, work therapy, recreational therapy, psychological treatment and other aspects of grooming to eliminate or reduce the various obstacles to the patient.
