Resumo
This study was carried out to evaluate the effect of the amount of colostrum (two and four liters) and methods of colostrum feeding (direct suckling from the cow, feeding colostrum using nipple bottle, and no feeding colostrum) on different blood traits. Thirty two Holstein calves (four groups of eight animals each) were randomly allotted to four treatments: treatment 1 - calves were hand fed four liters of colostrum; treatment 2 - calves were hand fed two liters of colostrum; treatment 3 - calves were fed colostrum directly from the cow, and treatment 4 - calves were not fed colostrum. Higher values of total serum protein, betaglobulins and gamaglobulins were observed in the calves after 24 hours of colostrum feeding. No differences among animals fed colostrum directly from the cow and hand fed two or four liters of colostrum were observed for total protein and eletrophoretic fractions. However lower values of total and eletrophoretic fractions were observed for calves that were not fed colostrum.
