Efficacy comparison of commercial porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae monovalent and bivalent vaccines against a dual challenge.

ABSTRACT: The objective of this study was to compare the efficacy of commercially available porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae vaccines. A total of 80 pigs was randomly divided into 6 treatment groups; 4 of the groups each received a different vaccine as well as a dual challenge. The remaining 2 groups were used as controls, 1 of which also received a dual challenge. Two of the 4 groups of pigs were administered 2 monovalent vaccines (designated as either monovalent vaccine A or B) of PCV2 at 7 days old and of M. hyopneumoniae at 21 days old. The remaining 2 vaccinated groups of pigs received a bivalent vaccine (designated as either bivalent vaccine A or B) of PCV2 and M. hyopneumoniae at 21 days old. All 4 vaccinated groups were challenged with M.
