摘要

Understanding maternally derived antibody (MDA) levels in peri-weaned pigs is critical in determining appropriate vaccination timing within the herd to avoid potential vaccination interference by MDAs. Measuring MDA levels is especially important in herds that utilize pre-farrowing vaccination in sows for determining when levels are low enough not to interfere. The study objective was to evaluate serological responses to a porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae (Mhp) combination vaccine in weaned pigs following two, one mL injections at three and six weeks of age (WO A). In addition, this study analyzed if MDA levels at the time of the first vaccination influenced post-vaccination antibody levels. The overall purpose was to determine if post-vaccination serology results are useful in determining if pigs received both vaccinations.
