Abstract

The aim of the paper was to evaluate the bovine colostrum quality and changes in composition during the first five days postpartum. Researches were carried out on a dairy farm with Holstein –Friesian heifer and multiparous cows. Samples of colostrum milk were collected at 1, 6, 12, 24, 48, 72, 96 and 120 hours postpartum. Samples were analyzed for chemical composition using an infrared spectrometer (fat, protein, lactose and dry matter), and for somatic cell count using a fluoro-optic-electronic method. In the first colostrum the concentrations of milk fat, protein and dry matter were high (7.07%, 20.86% and 30.19% respectively) with significant reducing after 12 hours postpartum. Lactose concentration was low at the beginning (1.23%) and increased slowly until the fifth day postpartum to 3.76%. Somatic cell count was high in the first milking (1,163,330 cells/ml) and decreased after that.
