The understanding of animal metabolism is important for the success of livestock activity. The aim of this study was to determine the serum biochemical profile of clinically healthy Jersey cows in pre and postpartum, housed in semi-intensive production system in Uberlândia, Minas Gerais, Brazil. Clinical examination and blood collection from 40 multiparous lactating dairy cows, between -150 days prepartum up to 60 days postpartum (DPP) were performed. At the laboratory, serum parameters of total proteins, albumin, globulins, urea, creatinine, non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), triglycerides, cholesterol, high density lipoprotein (HDL), very low density lipoproteins (VLDL), low density lipoproteins (LDL), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), creatine kinase (CK), calcium, phosphorus and magnesium were analyzed. To the total of cows (n=40) enrolled, only 21 cows were complied with the inclusion criterias. It was proceeded the Tukey test for parametric data, and to the nonparametric data it was held the Kruskal Wallis test for the comparison between days evaluated. There was no interference of negative energy balance and subclinical hypocalcemia in the occurrence of uterine diseases and reproductive performance. In conclusion, Jersey cows have biochemical profile characterized by hyperglobulinemia during peripartum, and high levels of triglycerides, but without impaired liver function and reproductive performance. |
