Determination of the significance of beta-hydroxy butyrate, non esterified fatty acids and some other serum biochemical parameters as predictors of left displacement of abomasum in cattle

Left displacement of abomasum (LDA) is one of the major metabolic diseases in dairy cattle which cause a large economic loss in dairy industry. Thus, predicting the occurrence of LDA, especially in early weeks post parturition is very important. In the present study, 14 biochemical parameters of cows with LDA before and after parturition were compared to those of healthy cows (control group) using logistic regression statistical model. Changes in six parameters, including beta-hydroxy butyrate (BHB), non-esterified fatty acids (NEFA), aspartate aminotransferase (AST), calcium, sodium and potassium were significant (p
