Preliminary study of the influence of plasma proteins on immunological and production parameters in pigs.
The health and productivity of pigs is important to farmers worldwide. One potential method of improving animal health is by providing functional proteins in the diet, for example spray-dried animal plasma (SDAP). These proteins, particularly plasma IgG, can improve health in many species, including humans. By unspecific activation of the immune system, SDAP can reduce morbidity and mortality as well as improve growth and efficiency what results in reduced costs of production. In this study, the influence of SDAP on expression of T-lymphocyte markers and production parameters in weaned pigs was evaluated. The results showed a significant increase in the percentage of T-lymphocytes, especially the CD8+ subpopulation, as well as a positive effect on body weight gain.
