During the hatching of chickens, ducks, geese and other poultry, hatchlings with difficult shelling often appear. For these young birds, artificial midwives can be performed in time to increase the hatching rate and the survival rate of young birds. Now we introduce the birth control technology of young birds as follows:
First, the appropriate time for midwifery. If less than one-third of the broken shell, endomembrane whitish, moist, clear and congested blood vessels, in such circumstances should not be artificial birth. Because at this time a little carelessness, the blood vessel is torn off, the embryo bleeds, will cause the death or the brood. If the broken shell is over one third, the intima is yellowed or yellowish, appear dry coke, no blood vessels are visible, the exposed hairs are dry, and even some places adhere to the shell membrane. In this case, artificial assistance must be performed in time. Production.
Second, the method of midwifery and should pay attention to the problem. When feeding chicks to midwifery, the eggs and shells that have been shelled, especially in small heads, should be carefully kept away from the shell membrane and the heads of the poultry embryos should be pulled out of the wings to allow them to earn their natural income. Out. In the process of gently peeling, if it is found to be dry, it can be moistened with warm water and then gently peeled. It is estimated that when the bird embryos themselves can get out of the shells by struggling, they must immediately stop tearing, and do not pull the body of the chicks out of the shell. Otherwise, it will cause the death or brooding of young birds.
