Biochemical Effects of Xylazine, Propofol, and Ketamine in West African Dwarf Goats.

Abstract

Anaesthesia was induced in West African Dwarf (WAD) goats using different combinations of propofol (P), xylazine (X), and ketamine (K), and the biochemical effect of the drugs determined. Twenty male (WAD) goats were randomly assigned to five treatment groups viz. Control (C) (2.5 mL IV normal saline); group K + X (5 mg/kg IV ketamine + 0.05 mg/kg IV xylazine), group P + X (5 mg/kg IV propofol + 0.05 mg/kg IV xylazine), group P + K (propofol 5 mg/kg IV + ketamine 5 mg/kg IV), and group P + K + X (propofol 2.5 mg/kg IV + ketamine 2.5 mg/kg IV + xylazine 0.05 mg/kg IV), respectively. There was increase (P < 0.05) in blood glucose in K + X, P + X and P + K + X. The serum cortisol level increased (P < 0.05) in all groups except in P + X. ALT value increased (P < 0.05) in K + X, P + K, and P + K + X. BUN increased (P < 0.05) in K + X but decreased (P < 0.05) in P + K + X. There was no significant variation (P > 0.05) in serum creatinine. These biochemical changes were transient. P + K + X would be the best drug combinations considering the biochemical parameter measured. However, data on blood glucose, ALT, BUN, and cortisol levels in an anaesthsized goat should be interpreted with caution in order to avoid erroneous interpretation in these animals.
