The study was designed to determine the effects of dystocia on plasma cortisol, cholesterol, and vitamin levels in heifers (n=22) and their newborn calves (n=22) at delivery. The animals were classified into 4 groups depending on calving difficulty. Plasma cortisol concentrations were significantly elevated in dystocia heifers (P<0.001) and their calves (P<0.019). Similarly, cholesterol levels were also markedly increased in dystocia heifers (P<0.001) and their calves (P<0.007). Vitamin A, β-carotene, and vitamin C levels were significantly decreased in dystocia calves. Overall, plasma glucose, HDL, triglycerides, and creatinine levels were all markedly increased in dystocia heifers as compared to controls. However, glucose, HDL, triglycerides, and creatinine levels were not changed significantly in affected heifers as compared to control group. Calving stress appears to affect several blood parameters including cortisol, cholesterol, and vitamin A in all the groups and β-carotene and vitamin C in the calves. The analyses of these parameters can be practical to improve the health of dystocia-affected mothers and to increase survival of their newborns.
