RESUMO:

The objective of this study was to correlate the blood urea concentration with the biochemical parameters of total calcium, magnesium and their influence on subclinical hypocalcemia in dairy cows, using twenty-seven cows of the Dutch breed, pre-calving the pastures fertilized with swine manure. Samples were collected in each animal from blood samples to obtain serum in the prepartum period (5 to 10 days before delivery) and at 24, 48 and 72 hours postpartum. Body weight, age, calving numbers and urine pH data were collected in prepartum. The biochemical parameters that presented a positive correlation (P<.05) were urea pre-urea24 (r=.34), urea24 with urea48 (r=.48), urea24 with Ca24 (r=. 49), urea24 with Ph urine (r=.38), and urea24 with Mg24 (r=.54). Other positive correlations (P<.05) were verified with pre-Mg and pre-Ca (r=.85), with Mg-24 and Ca 24 (r=.73), pre-Ca with Ca72 (r=.78). Negative correlations (P<.05) were observed for urine pH with pre-Ca (r=-.45), urine pH with Ca48 (r=-.41), Mg48 with Ca72 (r=-.40). There was influence of serum urea concentrations for Mg and Ca 24 hours postpartum.
