Reproductive activity in cows following parturition against values of certain parameters of metabolic profile

Data from literature indicate that there is a correlation between the values of reproductive parameters and the values of parameters of the metabolic profile, even though this cannot be confirmed in many cases. The objective of this work was to examine the connection between certain parameters of the metabolic profile and the restoration of reproductive activity in the postpartal period. Blood samples were taken from the cows involved in the experiment and values of parameters of the metabolic state were determined in 27 cows, of which 14 were primiparous and 13 multiparous. In the blood serum samples, we determined the concentration of glucose, total proteins, albumin, urea, and the activities of certain enzymes (alkaline phosphatase, ASAT and ALAT). It was established on the grounds of the obtained results that the delay in the establishment of reproductive activity in the postpartal period was in correlation with the blood concentrations of urea and albumin. .
