INFLUENCE OF TECHNOLOGICAL FEEDING REGIME IN NEWBORN CALVES ON SOME BLOOD PARAMETERS DURING THE WINTER
Keywords:
Black- and- White population, blood parameters, newborn calves, technological regime of feeding and raising, winterAbstract
We studied the influence of two different technological regimes of feeding and raising in newborn calves during the winter on some blood indexes, namely total protein, hemoglobin, hematocrit, erythrocyte count, cortisol and pH. The period of the first thirty days of their postnatal development has been followed. An experiment was carried out with 16 newborn calves from Black - and – White population, divided in two groups, 8 animals each. The calves from the first group received ad libitum colostrums by their mothers for 5 days. The animals from the second group were separated from their mothers and received aggregate milk. The both groups were raised in individual boxes outdoors. It was found that the calves from the first group have better adaptive capacity and health status.
