Abstract


The aim of the paper was to study the evolution of the immunoglobulin type IgG concentrations during the first threedays postpartum in Romanian Black and White cows. Researches were carried out on five Romanian Black andWhite primiparous cows. Samples of colostrum were collected at calving and at 4-hour interval for three days.Samples were analyzed for immunoglobulin concentration using ELISA test. The colostrum was analized in order tomesure immunoglobulin type IgG concentrations. The maximum concentration of immunoglobulin Ig G in colostralmilk was found as expected at the first milking 44.2 mg/ml. At the third, fourth, fifth and sixth milking from thesecond day after calving, respectively at 36, 40, 44 and 48 hours after calving immunoglobulin type Ig Gconcentration decreased to 32.8, 31.1, 29.6 and 26.8 mg/ml. At the sixteenth, seventeenth, and eighteenth milkingfrom the third day after calving, respectively at 64, 68, and 72 hours after calving immunoglobulin type Ig Gconcentration decreased to 22.6, 17.5, and 15.3 mg/ml.
