The aim of this study was to determine the impact of dietary changes during the suckling and post-weaning period on selected haematological, immunological and metabolic indices as well as the macro- and micro-mineral and antioxidant status of piglets. Twelve Large White piglets were kept according to the standards of pig rearing used in Slovakia until the end of the post-weaning period. Blood samples were taken from the piglets at the age of 30 days (the end of the suckling period) and 2 months (the end of the post-weaning period). At the end of the post-weaning period higher indices were found for RBC (P < 0.01), Hb (P < 0.01), WBC (P < 0.05), total Ig (P < 0.05), AST (P < 0.01), urea (P < 0.01), Se (P < 0.05), GSH-Px (P < 0.001), -SH groups (P < 0.01) and lower indices of albumin (P < 0.05), ALP (P < 0.001), LDH (P < 0.01), pancreatic amylase (P < 0.01), total lipids (P < 0.01), glucose (P < 0.01), total cholesterol (P < 0.01), bilirubin (P < 0.001), Ca (P < 0.01), SOD (P < 0.01), MDA (P < 0.01), vitamin A (P < 0.05), and vitamin E (P < 0.05) as compared to the end of suckling period. These results indicate that the dietary changes during suckling and post-weaning periods affected the majority of observed blood indices in piglets.
