Abstract
   The aim of the study was to follow the dynamics in certain blood indicators of liver and kidney function in terminal boars (Large White x Pietrain). We observed the changes in Cholinesterase U / L; Lipase U / L; ALT U / L; AST U / L; Alkaline phosphatase U / L; Creatinine μmol / L and Bilirubin μmol / L. In this study we found that the lipase and alkaline phosphatase tend to decrease with age. AST, ALT and creatinine are higher in older boars. Cholinesterase and bilirubin age changes are too small and are close to 5% variation. The first cluster includes individuals with higher cholinesterase, lipase and ALF (P<0.01), but considerably lower for creatinine (P<0.01). The second cluster includes thirteen-month-old boars with higher AST, ALT, bilirubin and creatinine (P<0.01) and respectively lower ALF (P<0.01).
