Intradermal injection of cattle
The solution was injected between the epidermis and the dermis for allergy test, and the site was selected on the side of the neck or the root of the tail. When injecting, the left hand picks up the skin, the right hand holds the syringe so that the needle and the skin pierce into the skin at an angle of 30 degrees, and slowly inject the liquid, showing a papular bulge at the injection site as the injection is correct. After the needle is pulled out, it is no longer sterilized or oppressed. Feel more strenuous during the injection, indicating that the injection is correct. If it is easy to inject, it indicates that the needle should be re-injected subcutaneously.
