Non-esterified fatty acids, ?-hydroxybutyrate, Creatine kinase MB, Insulin sensitivity, Cardiac troponin I.Abstract
The increase in energy imbalance at the beginning of lactation leads to metabolic disorders, especially clinical ketosis, in highly productive dairy cows. The objective of this study is to evaluate the clinical characteristics, biochemical parameters, and cardiac biomarkers creatine kinase MB isoenzyme (CK-MB) and cardiac troponin I (cTnI) of 15 cows diagnosed with clinical ketosis treated at the Bovine Clinic of Garanhuns at the Federal Rural University of Pernambuco. Nine of the 15 cows were diagnosed with primary ketosis and six had concomitant diseases, including left abomasal displacement, metritis, pneumonia, and renal failure. The observed clinical signs were non-specific and included decreased appetite and milk production and weight loss. Approximately 53% of the animals had central nervous system involvement. For biochemical evaluation, 15 high-production healthy dairy cows at the initial stage of lactation served as the control group. The data were subjected to analysis of variance for simultaneous comparison between two means allowing testing the hypothesis on the means of the different groups and subjected to Pearson correlation at a level of significance of 5%. The levels of ?-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), glucose, fructosamine, total protein, albumin, creatinine, aspartate aminotransferase, creatine kinase, CK-MB, and cTnI were higher in the group with ketosis. The diseased animals presented changes in glycemia, reduction in tissue sensitivity to insulin, and a lower RQUICKI-BHB index, especially hyperglycemic animals. The increase in the levels of cardiac biomarkers suggests the occurrence of myocardial injury associated with bovine ketosis.Downloads
