THE CLINICAL EVALUATION OF THE EFFECT OF XYLAZINE IN PREGNANT BUFFALOEs AND CATTLE

Abstract

The object of this study was to investigate the effect of xylazine administration at dose of (0.05 mg/kg BW) intravenously in late pregnancy of buffaloes and cattle. Under xylazine as sedation and analgesia, accompanied with local anesthesia, rumenatomy were implemented on three hundred seventy two buffaloes and sixty four cattle. Eighty two and thirty five of these buffaloes and cattle were in late pregnancy respectively. The results of this study revealed that xylazine did not effect the buffaloes in late stage of pregnancy, but it cause abortion in late pregnancy in cattle at a percentage of 3.65%. Also there was individual variation of response to xylazine in both buffaloes and cattle. The latter appeared to be more sensitive to xylazine than buffaloes
