Proper Injection Site Protocols

May 9, 2012 — 

The National Pork Board has published a factsheet, Proper Injection-Site Protocols to Prevent Violative Residues in Sows, to educate producers on proper injection technique to increase product efficacy and absorption, while reducing injection-site reactions, broken needles and residues.

The factsheet describes proper injection site selection and injection techniques to prevent broken needles and violative residues in sows. Simply observing the proper withdrawal time may not be enough to avoid a violative residue if excessive amounts of product are injected at a single site. Checkoff funded research indicates that the deposition of more than 10 mls at a single injection site may result in delayed absorption and possible violative residues at harvest. Injection sites should be varied by at least 3 inches when giving multiple injections at one time or over a course of multiple day treatment.
