Abstract

This study was performed to assess clinical signs, sedative and physiologic effects of a combination of fentanyl, azaperone and xylazine (F-A-X). The experiments were divided into four groups; xylazine 0.1mg/kg (X 0.1), F-A-X 0.05 MG/KG (F-A-X 0.05), F-A-X 0.1 MG/KG (F-A-X 0.1) and F-A-X 0.2mg/kg (F-A-X 0.2). Heart rates were decreased in all groups. Respiratory rates were decreased in other groups, but increased in F-A-X 0.2. Body temperatures were in normal ranges. After administration of F-A-X, most of cattle were recumbency and did not respond to needle prick. Duration of sedation was prolonged with increasing dosages. F-A-X did not induce sufficient analgesia for dehorning. Side effects were salivation and urination in all, but they were much less in F-A-X groups than those in X 0.1. Intermittent apnea and bloat were observed in F-A-X 0.2. Serum chemistry values were in normal ranges exvept for hyperglycemia invreased thorough experimental time. Based on above results, it may be concluded that F-A-X is effective preanesthetic with low dosage of 0.05~0.1 mg/kg being useful for immobilization or manipulation without tissue incision in cattle.
