Assessing the correlation between metabolic parameters and risk factors in transition cows

Our objective in this study was to evaluate the correlation between metabolic parameters included beta-hydroxybutyric acid, nonesterified fatty acids, magnesium, calcium and lactate as being continuous variables and some factors (age, lactation number, lactation stage, body condition score and feeding type) in transition cows. For this purpose, clinically healthy appearance Holstein cows (n=53) from different farms were assessed for analyzing at transition period. Blood samples were collected and measuring of parameters were done with cow-side devices weekly during the study. As a result, it has been seen that beta-hydroxybutyric acid, nonesterified fatty acids and calcium were affected by lactation stage with statistically significant (p<0.01). Moreover, effect of body condition score on nonesterified fatty acids was found to statistically higher
