Anesthesia was induced and maintained 2 hours by halothane in 5 sheep and 4 calves by closed circuit anesthetic machine. Average induction time was ~5 minutes in both groups. White blood cell count, packed cell volumes (PCV) blood urea nitrogen and serum glucose, cholesterol, total protein, protein fractions, creatine phosphokinase, alanine and aspartate transaminases, sodium and potassium were determined. Liver biopsies were taken two weeks after anesthesia10, 11 and were examined for any pathological changes using light microscopy. In sheep, blood PCV increased 1 and 7 days after induction and neutrophils by 2 hours whereas cholesterol declined 1-2 hrs. Pre-anesthetic serum cholesterol level was ~3 times greater in calves compared with sheep. There were no significant changes in any parameter in calves. Liver biopsies taken from sheep or calves 2 weeks after anesthesia did not indicate abnormalities and we found no prominent alterations in other biochemical parameters during or after anesthesia.
