Season’s effects on some clinical, hematological parameters and blood cortisol level in sedated Arabian horses with xylazine

Abstract Influence of heat or cold stress in sedated animals is unclear and requires further investigations. The present study aimed to evaluate the season’s effects on some clinical, hematological parameters and blood cortisol level in sedated Arabian horses with xylazine. Therefore, seven Arabian horses were used to investigate heart and respiratory rates, capillary refill time and serum cortisol level were recorded before (0) and 5, 15, 60, 180 minutes post sedation. Heparinized venous samples were collected before (0) and 3 hours post sedation for analysis of hematological analysis. Arterial blood samples were collected before and one hour post sedation for arterial blood gases and electrolytes analysis. Repeated analysis of variance (ANOVA) were performed (p
