Blood samples were collected from v. jugularis in five-day intervals from parturition to postpartum day 45 in the rearing conditions of a diary cow production herd, consisting of 10 groups with 10 pluriparous cows each (crossbreds of Bohemian Pied cattle with Holstein-Friesian cattle). In blood serum the following activities were determined photometrically: aspartate aminotransferase - AST (0.36-0.47-mu-kat. 1(-1)), gamma-glutamyl transferase - GMT (0.50-0.83-mu-kat. 1(-1)) and lactate dehydrogenase - LD (7.22-9.10-mu-kat. 1(-1))
