The mode of delivery may have a considerable effect on the state and health of the newborn. Therefore, the purpose of this study was to investigate the effect of a Caesarean section on oxidant and antioxidant status in newborn calves. This study included the neonates of 8 normally calved cows and 8 cows who had undergone by Caesarean section. Malondialdehyde concentrations were significantly higher in the calves delivered by caesarean section compared to the calves of normally calved cows, but catalase activity was significantly lower (P<0.01). Glutathione concentrations tended to increase in the calves delivered by Caesarean section compared to the calves of normally calved cows. There were no significant differences in the glutathione peroxidase activity between the groups. Our results suggest that the malondialdehyde concentrations and catalase activities, which show lipid peroxidation and antioxidant status in newborn calves, change due to Caesarean section. In conclusion, newborn calves are exposed to higher oxidative stress in Caesarean section. Key words: Caesarean section, newborn calves, oxidant and antioxidant status Nacin porodaja moze znatno utjecati na stanje i zdravlje novorodenceta. Stoga je svrha ovoga rada istraziti ucinak carskoga reza na oksidacijsko i antioksidacijsko stanje u netom oteljene teladi. Istrazivanje je provedeno na osam normalno oteljene teladi i na osam teladi oteljene carskim rezom. Koncentracije malondialdehida bile su znacajno vece u teladi oteljene carskim rezom nego li u prirodne oteljene teladi, ali je aktivnost katalaze bila znacajno slabija (P<0,01). Koncentracije glutationa bile su povecane u teladi oteljene carskim rezom u odnosu na prirodno oteljenu telad. Nisu bile ustanovljene znacajne razlike u aktivnosti glutation peroksidaze medu dvjema skupinama. Rezultati upucuju na zakljucak da su koncentracije malondialdehida i aktivnost katalaze kao pokazatelji lipidne peroksidacije ii antioksidacijskog stanja u novorodene teladi bile promijenjene zbog carskog reza. To govori da je netom oteljena telad zbog carskog reza izlozena jacem oksidacijskom stresu. Kljucne rijeci: cmski rez, telad, oksidacijsko i antioksidacijsko stanje
