Welfare assessment of dairy calves is commonly conducted through the observation of their behavior and the analysis of physiological parameters. Despite the large number of studies on this topic, there is a lack of research on the possible correlation between the physiological parameters and behavior at basal level in dairy calves. For this reason, the present study aimed to investigate the possible correlations between serum cortisol, neutrophil-to-lymphocyte ratio (N/L) and locomotor play behavior in 21 Friesian dairy calves within their first month of life. Every week, an arena test after blood collection was performed. A significant positive correlation between serum cortisol levels and N/L (rrm = 0.381; 95% CI = 0.083, 0.617; p = 0.012) and a negative correlation between time spent running and N/L (rrm = −0.351; 95% CI = −0.575, −0.077; p = 0.012) were found. On the contrary, no significant correlation between time spent running and cortisol levels was detected. Cortisol levels and N/L were higher in the newborn and had a constant decrease until reaching a stable value after the 24th day of life. These findings suggest a better predictivity of N/L, compared to serum cortisol, on locomotor play behavior.

Background: Methionine and choline may play role in maintaining health by metabolic optimization in transition Surti buffaloes. Present study has evaluated physiological, hematological, biochemical and thermographic changes on supplementation of rumen protected methionine and choline in transition Surti buffaloes. Methods: 27 Surti buffaloes were divided in 3 groups (n=9) as G-I, G-II and G-III. Apart from basal diet offered to G-I (control), supplementation of RPM in G-II and RPM+RPC in G-III was done from -15 d to 30 d postpartum. Dose per/animal/day of RPM and RPC was 10 g and 50 g respectively. Blood collection, measurement of meteorology, BCS, physiological parameters and infrared thermography were done -15 d, 1st, 3rd and 6th week of calving. Result: RPM and RPC supplementation increased BCS, blood glucose, TP, ALB, T3, T4, Ca, P and Mg levels and decreased BUN, Cr, AST, ALT, GGT, GLDH and cortisol levels during transition period in Surti buffaloes. RPM and RPC supplementation also decreased RT, TT and ET at 1st week postpartum period in Surti buffaloes. Supplementation of RPM +RPC as compared to RPM alone, gave better results in terms of biochemical analytes in transition Surti buffaloes.

<strong>Background:</strong> Increased blood flow may trigger pulmonary arterial wall inflammation, which may influence progression of pulmonary artery hypertension in patients with congenital heart disease. In this study, we aimed to investigate the correlation between preoperative inflammation markers and pulmonary arterial hypertension. <br /><strong>Methods:</strong> A total of 201 patients with pulmonary hypertension were enrolled in this study retrospectively; they had undergone open heart surgery between January 2012 and December 2013. Patients’ preoperative C-reactive protein (CRP), neutrophil to lymphocyte ratio, red blood cell distribution width, pulmonary pressures, and postoperative outcomes were evaluated.<br /><strong>Results:</strong> Patient age, neutrophil to lymphocyte ratio, red blood cell distribution width, and CRP were found to be significantly correlated with both preoperative peak and mean pulmonary artery pressures. These data were entered into a linear logistic regression analysis. Patient age, neutrophil to lymphocyte ratio, and CRP were found to be independently correlated with peak pulmonary pressure (P &lt; .001, P &lt; .001, and P = .004) and mean pulmonary artery pressure (P &lt; .001, P &lt; .001, and P = .001), whereas preoperative mean pulmonary artery pressure was found to be independently correlated with intensive care unit stay (P &lt; .001). No parameter was found to be significantly correlated with extubation time and mortality. Eighteen patients had experienced pulmonary hypertensive crisis; in this subgroup, patients’ mean pulmonary artery pressure and neutrophil to lymphocyte ratio were found to be significant (P = .047, P = .003). <br /><strong>Conclusion:</strong> Preoperative inflammation markers may be correlated with the progression of pulmonary hypertensive disease, but further studies with larger sample size are needed to determine the predictive role of these markers for postoperative outcomes.<br /><br />
