The serum protein profile from 15 newborn calves and 15 newborn kids submitted to natural suckling of colostrum. Animals were studied from birth to 60 days of age. The gana glutamyl transferase activity was higher in calves than in kids, but, in both species, the serum levels were higher in the first days of life. The total serum protein levels had no difference in relation to species and age. The albumin was the predominant fraction in the serum after the consumption of the colostrums, whereas increased levels occurred in calves from 48 hours after the colostrum intake and in kids after 15 days of age. Higher values of alpha globulin fraction in calves were observed at 24 hours of life, but in goats no significant changes were observed from 24 hours of age to 60 days of age. The beta globulin levels had no difference between species and age. At 24 of life, the gamaglobulins levels in calves and kids were 1.76 ± 0.92 g/L and 1.13 ± 1.24 g/L ( p = 0.3150), respectively. Lower values were observed at 30 days of age in calves and around 9 days of age in kids. The determination of serum protein profile and GGT are excellent indicators of passive immunity transfer in calves and kids. Colostrums from cattle had higher concentrations of immunoglobulins than that from goats. KEY-WORDS: calves, caprine, protein profile, colostrum, passive immunity
