Abstract


The aim of the paper was to evaluate the colostrum quality and changes in composition during the first three dayspostpartum. Researches were carried out on five Romanian Black and White primiparous cows. Samples ofcolostrum were collected at calving and at 4-hour interval for three days. Samples were analyzed forimmunoglobulin concentration using a ELISA test. The colostrum was analyzed in order to measure immunoglobulintype IgA and IgM concentrations. The maximum concentration of immunoglobulin Ig A in colostral milk was foundas expected at the first milking 4.2 mg/ml. The concentrations of immunoglobulin type Ig M decreased in the firstday after calving from 4.9 mg/ml at first milking to 4.2 mg/ml at the sixth milking. The concentrations ofimmunoglobulin type Ig A decreased in the third day after calving from 1.9 mg/ml at thirteenth milking to 1.5 mg/mlat the eighteenth milking. The concentrations of immunoglobulin type Ig M decreased in the second day after calvingfrom 2.9 mg/ml at thirteenth milking to 2.1 mg/ml at the eighteenth milking.
