Midwifery midwifery work

In the final stage of hatching, artificially shelled midwifery can be performed for the weak young chicks that are already shelled but unable to hatch. Normally, chicken embryos that are normal in development and have a more favorable fetal position are more concentrated in hatching, and there is a clear hatching peak (incubation to the morning of the 21st day).

The optimum time for midwifery of the chicks is 1-2 hours after the peak of the hatching and is performed when the allantoic blood vessels are withered. If the midwifery is too early, it will affect the normal hatching and cause stillbirth, weak brood due to massive bleeding, or premature formation of water due to premature shelling. Smothered in the shell. During the midwifery period, the upper half of the chicken embryo is peeled off, and the head bent under the abdomen or wings can be pulled out, and the mucous and dirt around the nostrils of the embryo body can be removed to avoid clogging the breath. Some of the bonded chicken embryos can be moistened with warm water, and then scissors or forceps can be used to gently cut open or pick out the mucous membranes to slowly develop the limbs and allow them to break the umbilical husk. When peeling the shell, the large blood vessels that are not constricted on the surface of the fetal membrane should be noticed to avoid death due to improper operation. Since the eggs are stripped and the water evaporates more, the relative humidity in the incubator can be appropriately increased and can be increased to more than 90% if necessary.
