Evaluation of changes in behavior, heart rate and rectal body temperature in calves during two hours after birth

The present experiment focuses on the evaluation of behavior Holstein calves in first two hours after birth. research took place at Slovak University Agriculture Farm Oponice. calf sample consisted 11 individuals. lying, standing, moving were scored and number attempts to lift head, latency head lifting, stand up up, ears shaking. Behavior was evaluated by next traits: total duration standing moving, average one bout percentage rate occurrence bouts for all traits, mean inter-event interval traits. basic physiological parameters (heart – HR rectal temperature RT) measured four 15 minute intervals during hour birth (M15, M30, M45 M60). Difference between second observation tested non-parametric Kruskal Wallis test. Relation among traits analysed Spearman rank correlation. examined 1 4 minutes (±0.33 seconds). Positive correlations (P<0.05) found many signs (total time shaking).
