AbstractThe objective of the study was to determine the influence of Czech Fleckvieh cow's condition before parturition on chosen blood biochemical indices in perinatal period and at the beginning of lactation. The study was conducted on 38 multiparous cows 3-14 days prepartum. The cows were selected with respect to body condition score (BCS): BCS>4 points (group I, n=18) and BCS<4 points (group II, n=20). Blood was collected at 3-14 and 1-2 days prepartum and 1-2, 21 days postpartum and analyzed for lipid-carbohydrate, protein parameters and enzymatic activity. Cow's condition, milk yield and composition were also estimated. Changes in Czech Fleckvieh cow's condition in a transition period do not have any clear influence on milk yield and composition. An excessive BCS before calving leads to its higher decrease at the beginning of lactation and may indirectly point to a higher energy deficiency in the first period of lactation. It is confirmed by glucose concentration in blood serum decrease (P<0.01) in 3rd week of lactation when compared to cows with a proper condition before calving (3.39 vs. 2.45 mmol/l). Overnormative condition before calving also negatively influences the content of triacylglycerols, alkaline phosphatase and total bilirubin in blood serum in the first days postpartum. TAG transport from liver to blood is impaired at the beginning of lactation in cows with high condition prepartum. The study demonstrated that in Czech Fleckvieh dairy type cows intensified lipolysis and ketogenesis in perinatal period do not take place pointing to high adaptation possibilities of their metabolism.
