Transient anorexia and abrupt deprivation of lactogenic bio-active compounds are major factors in the multifactorial etiology of diarrhea and/or transient weight dip following weaning. Dietary spray-dried porcine plasma (SDPP) stimulates post-weaning feed intake in piglets and is an alternative source of immunoglobulins and other glycoproteins present in sow’s milk. The production process of HAT-SDPP includes an additional anti-viral treatment in which plasma is treated at pH 10.2 and 48°C for 10 min., but effects of dietary HAT-SDPP on piglet performance have not been evaluated yet. The aim of this study was to evaluate the effect of SDPP and HAT-SDPP on post-weaning piglet performance under conditions of absence of prophylactic use of antibiotics. We hypothesized a considerable incidence of postweaning diarrhea and impaired performances in control piglets.
