Final answer:
Subcutaneous injections in swine are given in the neck region, behind the ear, and aseptic technique should be followed.
Step-by-step explanation:
Subcutaneous injections, also known as SC injections, are given just under the skin of pigs. In swine, the best location for subcutaneous injections is in the neck region, just behind the ear. This area provides easy accessibility and allows for proper absorption of the medication.
When administering subcutaneous injections to pigs, it is important to follow proper aseptic technique to prevent contamination. Make sure to clean the injection site with an appropriate disinfectant and use a sterile needle and syringe.
