title: [Adaptation reaction of dairy calves in the first days of life. Effects of type of delivery and individuality of the newborn].
abstract: Surveying a calving period of tethered dairy cows, newborn dairy calves of different breeds were investigated just after birth and at 24 hours and 48 hours of their postnatal life as well. Blood samples taken by venipuncture in calves were analyzed for acid-base-balance, hemoglobin, catecholamine and cortisol. Comparing the mean values of the newborns from calvings without assistance, with slight pulling and with heavy pulling, differences could be found only in the first hours of postnatal life between some of them without hemoglobin content of the blood that was of individually specificity and all the time lowest in calves delivered by heavy traction. Great scattering of and strong relationship between some of the measured values are assessed on the basis of constitutional features, maturity and adaptability of the calves.
