The knowledge of animal metabolism is critical for success in any activity involving livestock. This study aimed to determine the serum biochemical profile of Jersey cows during peripartum and to correlate it with the occurrence of uterine diseases. For this, blood samples were collected 15 times from 150 days prepartum to 60 days postpartum (DPP) of 31 cows with physiological postpartum (n = 21) and uterine diseases (n = 10). Cytological endometritis diagnosed at was DPD 28 when the number of neutrophils was ≥ 10%. Proceeded to Tukey\'s test for parametric data and parametric not held the Kruskal Wallis test for the comparison between the evaluated times. The comparison between groups was performed by analysis of variance (two-way ANOVA). To analyze the reproductive efficiency proceeded to the Mann Whitney test Fisher\'s exact and Log rank. There was no interference of negative energy balance and subclinical hypocalcemia in the occurrence of uterine diseases and reproductive performance and none of the biochemical parameters analyzed during labor was able to indicate or predict uterine infections. It was concluded that Jersey cows have biochemical profile characterized by hypoalbuminemia and striking hyperglobulinaemia during postpartum, and high levels of triglycerides and cholesterol, but without impaired liver function. Jersey cows with uterine diseases have severe hypoalbuminemia in the immediate postpartum period, and hypomagnesaemia, hiposfosfatemia and hypocalcemia postpartum late.
