Key Points and Detailed Operation Methods of Partridge Incubation Technology
The partridge is a relatively common bird in China, with a wide distribution range across the country. Partridge meat is rich in protein and other nutrients beneficial to the human body, and it also has various effects such as treating anorexia and emaciation. Today, its farming area in China is also very large. When raising partridges, we must do a good job in partridge incubation to ensure partridge production. So let's take a look at partridge incubation technology together with the editor below!
1. Egg selection
The breeding season of partridges is generally around April to May each year, and March is the courtship season for partridges. Under normal circumstances, each partridge lays about 5 eggs. When incubating partridges, we first need to do a good job in selecting breeding eggs, and the breeding eggs selected should mainly be those within half a month. Breeding eggs must not be double-yolk eggs, deformed eggs, or other poor-quality eggs, and these should be picked out in time. Then soak the breeding eggs in warm water at about 30°C for about 5 minutes, and an appropriate amount of potassium permanganate should be added to the water. After soaking, take the eggs out and let them dry, ready for incubation.
2. Setting eggs
After completing the treatment of partridge breeding eggs, preheat the breeding eggs slightly and then place them in the setting tray to begin preparing for incubation. When setting the eggs, be sure to control the direction of the breeding eggs well, placing them in the egg tray with the large end facing up at a certain angle, preferably at the center point. After arranging the breeding eggs, place the egg tray into the incubator. After placing it in the incubator, be sure to secure the egg tray firmly to prevent it from loosening and falling during egg turning.
3. Egg turning
During the incubation of breeding eggs, we must do a good job in turning the eggs to avoid the phenomenon of embryo adhesion in the breeding eggs. In the early stage, the yolk of the breeding eggs will float upward. If the eggs are not turned in time, the yolk will adhere to the eggshell membrane, reducing the hatch rate. If the eggs are not turned in time in the middle stage, the allantois will adhere to the yolk sac, causing embryo death. At about the first three weeks of incubation, turn the eggs about once every 3 hours, and then after 20 days, as the embryos have gradually developed and taken shape, egg turning should be stopped.
4. Cooling eggs ⟧11⟧After the breeding eggs enter the middle and late stages of incubation, they will produce a large amount of body heat, so at this time we need to use the method of cooling the eggs to dissipate heat. About half a month after the breeding eggs are set, cool the eggs once a day, and stop when the temperature drops to about 35°C. In the later stage, the temperature on the egg surface will reach nearly 40°C. At this time, cooling the eggs cannot rely only on ventilation; appropriate water spraying is needed, and the water temperature should be kept at about 18°C. Egg cooling can be carried out in combination with egg turning.
After hatching eggs enter the middle and late stages of incubation, they generate a large amount of goose body heat, so at this time we need to use the cooling method to dissipate heat. About half a month after the hatching eggs are placed in the incubator, cool the eggs once a day, stopping when the temperature drops to around 35°C. In the late stage, the temperature on the egg surface can reach nearly 40°C. At this time, cooling the eggs cannot rely on ventilation alone; appropriate water spraying is needed, with the water temperature kept at around 18°C. The cooling work can be combined with turning the eggs.
5. Candling eggs
During the entire incubation period of partridges, candling should be done about 3 times, once each in the first, second, and third weeks after setting. The first candling should remove unfertilized eggs and dead embryo eggs. After candling, normal eggs show radial blood vessels and are relatively red, while infertile eggs have no blood vessels and only the yolk can be seen. Then, during the second and third candling, dead embryo eggs should also be removed to maintain the hatch rate.
The above is a brief introduction to partridge incubation technology. During incubation, we should control temperature and humidity well, and then do a good job in transfer to hatching trays, chick collection, and other work to ensure the hatch rate. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
