Spray-dried animal plasma (SDAP), a natural byproduct of the meatpacking industry, has been shown to have beneficial effects on growth and performance of weaned pigs. Porcine circovirus 2 (PCV2) is an important virus that is disseminated in the pork industry. Regardless of the studies evaluating the possible transmission of PCV2 through SDAP, there is no information about the effects of its inclusion in the PCV2 loads in natural infections. The present investigation evaluated the influence of dietary inclusion levels of SDAP in weanling pigs on PCV2 viremia and humoral immune response. Fiftysix weaned piglets were fed in a 2-period feeding program. Dietary treatments included 0%, 2%, 4% or 6% and 0%, 1%, 2% or 3% of SDAP during period 1 (14 to 28 days old) and 2 (29 to 42-days old), respectively. In period 3 (42 to 56 days old), all piglets received a SDAP-free diet. Serum samples were collected weekly and tested for PCV2 antibodies and DNA load. The results show that the concentration of 6% and 3% of SDAP on feed offered for pigs during period 1 and 2, respectively, may have decreased the PCV2 loads.
