Serum immunoglobulins G and M concentration in the serum of holstein calves until 90 days old
Keywords:Colostrum, Immunoglobulins, Calf and passive immunity
AbstractThis study evaluated the G and M concentrations in serum of 32 calves until 90 days old, considering the way (direct suckling from mother or by bottle) and the volume of ingested colostrum. The calves were divided into 4 groups. Group 1: four liters of colostrum fed by bottle; Group 2: two liters of colostrum fed by bottle; Group 3: direct suckling from mother and and Group 4: two liters of milk by bottle. Serum IgG concentrations obtained in this study had no significant difference in the way of colostrum feeding (direct suckling from mother or by bottle), but their levels were higher in the former way of administration of colostrum, followed by those which received 4 liters of colostrum. Those animals which were not fed with colostrum presented IgG and IgM levels earlier, from 30 and 15 days old, respectively.
