The key technology in turkey hatching

Turkey is native to the Americas and belongs to herbivorous, grain-saving, game and rare birds. Since its introduction in China is not long, its incubation still needs further exploration and research. After years of practice and exploration, we have summarized some shallow experiences. Everyone, for reference.
(I) Preservation of eggs Preservation of egg storage rooms is a condition requiring good heat insulation, dust-proof sand, and elimination of mosquitoes, flies, mice, etc., against sun exposure or drafts. Generally, the carton box can be used to drill more ventilated eyes in a cool, dry and ventilated place. Preservation should have the conditions: (1) The temperature is 10-15 °C. 15°C within 1 week and 10-12°C after 1 week. Eggs that have just been produced should have a 24-hour cooling process and cannot be delivered to the egg storage room immediately. (2) Humidity is 75%-80%. It should be noted that excessive humidity may cause mildew. (3) turn the egg. More than 1 week of fire eggs turn 1-2 times a day, change the direction of 45-90 degrees. (4) When the eggs are released, they should be headed upwards. The storage time of eggs is 7-20 days. (b) scientific selection of eggs (1) look outside. The eggs that can be hatched are of a moderate size and oval shape; the egg surface is clean, shiny, uniform in shell quality, moderate in hardness, and bright in shell color. (2) Lights. Use eggs or bright light to observe the eggs, with a small air chamber, clear egg yolk, uniform protein concentration, no foreign body in the egg. If cracks, blood spots, and egg yolks are not dark yellow or dark red eggs are not used. (3) Internal inspection. Sampling a few eggs open, fresh protein is thick, egg yolk uplift; fresh protein is thin, egg yolk is relatively flat; egg yolk to protein ratio is 2:1. (III) Sterilization of Eggs Enter the disinfection room or disinfection room immediately after each egg collection. Eggs are not allowed to stay overnight in the house. Pre-incubation eggs can be decontaminated by formaldehyde fumigation, benzalkonium disinfecting, potassium permanganate or iodine solution disinfection, and ultraviolet irradiation, to kill the original microorganisms and bacteria, reduce dead embryos and improve hatching. Rate and chick survival rate.
(4) Natural hatching Small bettas and other small turkeys are particularly strong in nests, and nest 4-7 months in one year. Every 15-22 eggs will have a nest. At this time choose a quiet, weak light, small temperature difference places (such as sheds and other indoor) nailed with a brick or brick 50cm x 30cm x 20cm slot or use a large cardboard box for nests or wood shavings, etc. Then add about 20 eggs to allow the mother turkey to hatch naturally. Combine eating, drinking, and urinating every day for 10 to 20 minutes without the need to manually turn eggs. On the 5th, 11th, 18th, and 25th days, each egg was cut once, eliminating useless eggs other than live embryos. If there are not many useful eggs in the nest, the hens with similar incubation periods can be merged to increase the utilization rate of the hens. The average turkey hatching period is 26-28 days.
(5) Artificial hatching In order to increase the turkey production rate, hatching can also be performed by artificial hatching method. In combination with the use of the “Turkish Husband Wake-up Calling Method”, the mother turkey that has a nesting behavior can be awake and enter the laying period in time. This can increase the average female turkey from 80 to 120 eggs per year to 150 to 190. The incubation measures are:
1.Temperature: The temperature of fire eggs is controlled from 1 to 18 days after incubating to 38-38.4°C, from 19-22 days to 37.5-38°C, and from 23-25 ​​days to 37.2-37.5°C and 26-28 days. The hatchling temperature is 36.8°C.
2.Turn the eggs: Turn eggs 1 to 16 days every 2 hours according to the angle of 40-45 turning the eggs 1 time, 17-25 days per hour to transfer eggs 1 times. Turning the egg requires “light, fast, steady”. Do not turn the egg on the 26th day, and let the big head face up to prepare for hatching. And combined with turning eggs 1-3 times a day, each time 5-10 minutes, the temperature dropped to 33-35 °C can be.
3. According to the egg and humidity: Incubation of eggs to regular egg, timely removal of useless eggs, according to the egg method with the above natural incubation method. The relative humidity of the turkey is kept between 60% and 65% for 1 to 18 days, 55% to 60% for the 19 to 22 days, and 70% to 76% for the 23 to 26 days. After entering the breeding period, increase the ventilation volume, require uniform ventilation and appropriate wind speed, and do not blow directly on the fire eggs. The oxygen content is 21%, and the carbon dioxide content is less than 0.5%.
4. Stimulation hatching: After 28 days, unhatched turkey embryos can adopt high temperature and high humidity method to stimulate seedlings. Spraying the eggs once a day with a spraying method and maintaining the temperature at 38.2-38.5°C can achieve the desired effect.
(6) When the hatchlings and artificial fire eggs hatch into 26-28 days, there will be a large number of shells hatching. The brood should be chopped once every 3-5 hours, and the umbilicals should be properly deflated. The fluffy chicks should be picked out (at the same time, the eggshells must be removed) and placed in a pre-prepared brooding room for brood management. Live embryos that are not sufficiently robust or have thick shells can be artificially assisted. If it is not broken shell and hear the shell chicken or broken shell less than 1/3, the intima from the wet, blood vessels clear and congested; even broken shell has been over 1/3, but hair yellow, hair slightly coke, Some of the cases of endometrial enwrapped embryos, etc., should be artificially assisted. Midwifery should be peeled off gently. Once the head of the embryo is exposed, it is estimated that the shell can be freed from the shell, and the operation should be stopped and allowed to come out of the shell. For small broken shell eggs, carefully dig out a small air vent at the break and wait for its natural shell. For the weak youngsters who help the output, they must take care of them carefully. In case of umbilical bleeding, sprinkle some anti-inflammatory powder in time.
