Spring is the golden season of poultry hatching. In order to create good conditions for the embryonic development of poultry eggs, and to obtain a large number of excellent quality young chicks, it is necessary to use excellent hatchery equipment and use them correctly.
First, pick
Hatcheries and professional households should consider the following aspects when choosing an incubator.
(a) The hatching rate. The level of hatching rate is the most important indicator to measure equipment quality, and it is also the main reason for many hatchery and professional households to spare no expense in replacing advanced hatchery equipment. The temperature field inside the machine should be uniform, there is no temperature dead angle, otherwise it will reduce the hatching rate.
(b) Machine use costs. Such as electricity costs and maintenance costs.
(3) The circuit design should be reasonable and there should be perfect aging testing equipment. In addition, the whole machine should be tested for aging for a period of time after it has been tested.
(d) good after-sales service. One is the speed of service, and the other is long service hours. As far as possible, manufacturers with large scale, good reputation and long after-sales service should be selected.
(five) long service life. The service life of the incubator mainly depends on the material of the material, the thickness of the material used, and the quality of the electrical components. The user should compare the details when purchasing. In addition, the type of product is also a particular area of ​​attention when selecting an incubator.
Second, use
(a) Preparation before hatching. 1. Before installation, the concrete floor should be kept flat. The hatching machine is slightly forward (some models are backwards) inclined to discharge the sewage when cleaning. Keep 2 to 3 meters of operating space in front of the door. 2. Incubator disinfection should be done 1 week before hatching. All corners of the hatchery should be cleaned and disinfected with potassium permanganate and formaldehyde. 3. Check whether the egg tray frame is firm and whether the wire is dislocated, broken or bent, etc., so that one by one is checked. 4. Check whether the hatchery is closed tightly, whether the walls of the hatching chamber, the top, and the floor are deformed, etc., and find that the problem is repaired in time. 5. One week before hatching, it is necessary to systematically check whether the installation is firm and whether the electrical system wiring is accurate and reliable. 6. Inspection process. During the trial run, check the rotation of the system for supplying temperature, humidity, alarm bells, fans, etc., and check the rotation of the motor. Everything is normal, and the test run can be formally hatched within 1 to 2 days. For the preparation of eggs prior to hatching, the pre-incubation selection of the eggs should be done first, ie external observation, screening and necropsy. Secondly, preheating and disinfection of the eggs prior to hatching should be done.
(b) Management during incubation. 1. Eggs are hatched. Eggs on the plate are preheated and sterilized before hatching. When the eggs are hatched, insert the egg tray into the egg rack in the incubator. But pay attention to the balance of the egg rack to prevent turning eggs. 2. Temperature regulation and ventilation. After the temperature is adjusted and fixed, it is generally not necessary to move. When the hatching is started, some of the heat is lost due to the opening of the egg. At the same time, the eggs and the egg trays absorb heat, and the temperature in the incubator falls sharply. This is a normal phenomenon. Will gradually return to normal. Under normal circumstances, when the temperature inside or outside the machine is 0.5°C, it is necessary to check the reason and adjust it. Therefore, it is necessary to observe the temperature indicated by the thermometer on the door at any time. If it is abnormal, check the temperature control system in time. Troubleshooting. As the embryonic age increases, the exhaust port should be properly opened, and it should be fully opened later to maintain the oxygen requirement of normal embryonic development. However, the early stage should not be opened too large to avoid slow heating and waste of electricity. Generally, the temperature in the incubator is required to be about 38°C during the incubation period of 1 to 19 days. When the embryonic egg is moved into the hatcher, the temperature of the hatcher must not exceed 37.5°C. When using an incubator, be aware that it must be used at the recommended temperature of the incubator manufacturer's instructions, and also consider the environmental conditions.
(c) humidity regulation. The optimum relative humidity in the incubator is 53% to 57%. During the incubation period, the wet and dry bulb thermometer in the glass window of the hatchery door must be observed regularly. In addition, the water in the wet and dry bulb thermometer basin should be replaced frequently.
(d) turn the egg. It is required to turn the egg once every 2 to 3 hours, and the turning angle is 45. If multiple hatchers are controlled at the same time, it is best to turn all eggs in the same direction when turning the eggs. Record every time you turn the egg.
Third, post-hatching management
Embryos hatch for 18 to 19 days and should be transferred to hatchers to continue hatching until hatching. Increase the room temperature when transferring eggs. The movement should be light, steady and fast. When the embryonated eggs hatched to 20.5 days, they began to hatch a large number of shells. When more than 30% of the shells hatched, they began to pull out the chicks whose feathers had basically dried, and pulled out the eggshells. When the feathers were not dry, the chicks were hatched or allowed to hatch. Chicks stay in the hatcher for too long and affect chick health. After hatching, hatchers and hatchery rooms must be cleaned and sterilized. The hatching tray and the water tray are rinsed and placed in a hatcher for fumigation.
