Spring is the golden season for poultry hatching. In order to create good conditions for embryonic development of poultry and eggs, and to obtain a large number of good quality poultry, it is necessary to use excellent hatching equipment and use it correctly.

First, pick

Hatcheries and professional households should consider the following aspects when purchasing incubators.

(1) Incubation rate. The hatching rate is the most important indicator to measure the quality of equipment, and it is also the main reason why many hatcheries and professional households spare no expense to replace advanced hatching equipment. The temperature field inside the machine should be even, there is no temperature dead angle, otherwise it will reduce the hatching rate.

(2) Machine use cost. Such as electricity and maintenance costs.

(3) The circuit design should be reasonable and there is perfect aging detection equipment. In addition, the whole machine should be aging test for a period of time after being installed, and it can only be used after leaving the factory after passing the test.

(4) Good after-sales service. First, the speed of service is fast, and second, the service time is long. Manufacturers with large scale, good reputation and long after-sales service should be selected as much as possible.

(5) Long service life. The service life of the incubator depends mainly on the material of the material, the thickness of the material used and the quality of the electrical components. Users should compare them in detail when purchasing. In addition, the product type is also an aspect that should be taken care of when choosing an incubator.

Second, use

(1) Preparation before hatching. 1. The concrete floor should be kept flat before installation. The incubator is tilted slightly forward (some models are rearward) so that the water can be drained during cleaning. There must be 2 to 3 meters of operating space in front of the machine door. 2. The disinfection work of the hatchery should be carried out 1 week before the hatching. All corners of the hatchery should be cleaned and disinfected with potassium permanganate and formaldehyde. 3. Check if the egg tray is firm and the wire is dislocated, broken, bent, etc., and check one by one. 4. Check whether the hatching chamber is tight after closing, whether the four walls, the top roof and the bottom plate of the hatching chamber are deformed, etc., and the problems are repaired in time. 5. 1 week before hatching, the system should be checked whether the installation is firm and the wiring of each electrical system is accurate and reliable. 6. Inspection during the test machine. During the test, the system should be inspected for temperature, humidity, alarm bells, fans, etc., and the rotation of the motor. Everything is normal. The test machine can be used for 1 to 2 days before it can be officially hatched. For the preparation of the eggs before they are hatched, the eggs should be selected before the hatching, that is, external observation, egg laying and necropsy. Secondly, preheating and disinfection of the eggs before they are hatched should be done.

(2) Management during the incubation process. 1. Eggs are hatched. The eggs after the plate are pre-heated, disinfected and then hatched. Insert the egg tray into the egg rack in the incubator when you are in the incubator. But pay attention to the balance of the egg rack to prevent turning the eggs. 2. Temperature regulation and ventilation. After the temperature has been adjusted and fixed, generally do not move again. When you first enter the hatching, due to opening the door to release the eggs, some of the heat is lost. At the same time, the eggs and the egg trays need to absorb heat. The temperature inside the incubator drops sharply. This is a normal phenomenon. Will gradually return to normal. Under normal circumstances, when the temperature inside the machine is high or low 0.5 °C, the cause should be checked and adjusted. Therefore, the temperature indicated by the thermometer on the door should be observed at any time. If it is abnormal, check the temperature control system in time. Troubleshoot. As the embryo age increases, the vent should be properly opened and should be fully opened later to maintain the oxygen requirements of normal embryo development. However, it should not be opened too large in the early stage, so as to avoid slower heating and waste of electricity. Generally, the temperature in the incubator is about 38 °C when it is hatched for 1 to 19 days. When moving the embryo into the hatcher, the temperature of the hatcher should not exceed 37.5 °C. When using the incubator, be sure to use the temperature recommended by the manufacturer's instructions for the incubator, and also consider the environmental conditions.

(3) Humidity adjustment. The optimum relative humidity in the incubator is 53% to 57%. During the incubation period, the dry and wet bulb thermometer in the glass window of the incubator door should be observed regularly. In addition, the water in the wet and dry bulb thermometer basin should be replaced frequently.

(4) Turning eggs. It is required to turn the eggs once every 2 to 3 hours, and the angle of turning the eggs is ±45°. If you control multiple incubators at the same time, it is best to turn all the incubators in the same direction when turning the eggs. Make a record every time you turn the eggs.

Third, the management of the late incubation period

Embryo eggs hatch for 18 to 19 days and should be transferred to the hatcher to continue hatching to hatching. To increase the room temperature when turning eggs, the movement should be light, steady and fast. When the embryo egg hatches to 20.5 days, a large number of clam shells are hatched. When more than 30% of the eggs are unshelled, the chicks whose feathers have been basically dried are taken out, and the eggshells are taken out. When the chick feathers are not dry, the chicks are checked or given. Chicks staying in the hatcher for too long, affecting the health of the chicks. After the hatching is completed, the hatchers and hatcheries must be cleaned and disinfected. After the brooding tray and the water tray are rinsed, put them into the hatcher for fumigation.
