DIAGNOSIS OF PASSIVE IMMUNITY TRANSFER FAILURE IN CALVES BY TOTAL PROTEIN AND ITS ELETROPHORETIC FRACTIONS, IMMUNOGLOBULINS G AND M QUANTIFICATION AND GAMMA GLUTAMYL TRANFERASE ACTIVITY IN SERUMAbstract
The total protein and its fractions (albumin, alpha globulin, beta globulin and gamma globulin), G and M immunoglobulins and the activity of gamma glutamyl transferase were determined in the blood samples of 40 calves, 24 hours old, in an attempt to identify calves with failure of passive immunoglobulin transfer. The majority of newborn calves that died in the first months of life had lower levels of total protein, beta globulin, gamma globulin, IgG, IgM and GGT, than those found in newborn calves that survived.
