Lymphocyte B population in calves under different breeding conditions.
Using the EAC rosette test 176 lowland black white (lbw) and lowland red white (lrw), 0-130 day-old calves were examined to determine the number of lymphocytes B. The calves came from 2 farms with different industrial breeding technology. Farm A was characterized by a considerable mortality of the animals due to diseases typical for the neonatal period, whereas in farm B no deaths were noted. As the result of examinations it has been found that calves from farm A showed an appreciably higher incidence of lymphopenia with concomitant higher maximal numbers of EAC-rosettes-forming-lymphocytes.
