Under normal circumstances, the incubation period of the blue peacock is 27-28 days, but because the artificial hatching technique of the blue peacock is not very mature, in the later period of hatching, the proportion of the death of the fledgling may account for more than 70% of the total number of embryonic deaths. Therefore, in addition to providing proper hatching conditions during the hatching period, it is also necessary to strengthen the responsibility of hatchers and provide timely production assistance.
1. Selection of Artificial Midwifery Time Blue peacock breeder eggs should be checked daily for embryo activity after 25 days of incubation. When the embryonic allantoic blood vessels have been found to have completely shrunk and no bright red blood vessels are present at the lower edge of the air chamber, the surface of the air chamber is tilted to one side, suggesting that the childishness will soon be broken. In the oyster shell, the embryonic bird first stretches the head number from the two legs and the wings toward the air chamber, uses the “broken shell tooth†to break the inner shell membrane and enter the air chamber, and then begins to strike at the boundary of the near air chamber. If the embryo egg is placed close to the ear at this time, you can hear the sound of the pipa shell in the egg, or the chirping sound of the fledgling bird, and the sound gradually increases and the interval time increases. The shorter, this means that the chicks are about to hatch. If the clam shell sound and the chirping sound of the chick gradually weaken, and the interval time is extended, artificial midwifery should be considered; some embryonic birds may break the shell by themselves, and may find cracks or small holes in the air chamber but are punctured. After 8-12 hours, there are still no signs of shelling, and when the inner shell membrane has yellowed through the small holes, the egg shell should also be opened from the broken hole so as not to cause death of the embryonic bird. In the hatching process, there are often nestlings that open the eggshell to a large area and the pods extend out of the shell. Due to the limited space of the activities, the broken shell muscles of the chick's neck are often unable to retract the stretched pods. Into the egg to continue shelling, this type of egg should be considered the air chamber border withered state, timely midwifery.
2. The operation steps of artificial midwifery According to the operation sequence of artificial midwifery, artificially it is generally divided into three parts, namely artificial shelling, artificial shelling and hatchery midwifery. Artificial shelling is to make a small hole in the air chamber, or expand the broken hole, and then gently peel the shell to expose the head of the chick. Before stripping the eggshell membrane, check the blood vessel's shrinkage. If the eggshell membrane is whitish and the internal blood vessels are thick, use a warm towel or transparent tape to re-seal the hole and wait for a while; if the eggshell The outside of the membrane yellows and begins to dry, and artificial midwifery can be performed. When you are midwifery, use your fingers to gently hold the young bird's cockroach. Pull the head out of the egg shell and put it into the hatchery. The chicks can get out of the shell. However, for a longer shelling time, the fledglings of the fledglings are already dry and the allantoic blood vessels have shrunk. If the fledglings are hopeless, they should be soaked in the disinfectant solution, carefully peeled off, and sterilized the umbilicus. .
3. Nursing care of young chicks after artificial birth The blue peacock chicks that are artificially assisted by labor are generally weak in strength. To ensure that the weak chicks recover their stamina as soon as possible and to promote the absorption of the yolk and the healing of the umbilicus, the young chicks should be kept in the hatching. 12-24 hours in the tray, until the baby fluff dry, can stand on their own and then transferred to the brooding room, according to weak chicks feeding management, in order to ensure a higher survival rate of brooding.
