DEPLETION OF PENICILLIN G RESIDUES IN SOWS AFTER INTRAMUSCULAR INJECTION

The ultimate objective of this research is to provide pork producers with practical treatment and withdrawal guidelines for the use of penicillin G procaine in sows. Specific objectives are to: 1) provide the pork industry guidelines on appropriate patterns of intramuscular delivery of penicillin G procaine to sows; 2) provide the pork industry with appropriate withdrawal periods for sows treated with penicillin G procaine under treatment conditions typically recommended by veterinarians; and 3) to determine the incidence of "false-positives" returned by the "Charm-KIS" microbial inhibition test under controlled conditions.
