The aim of this research has been to examine concentration of the main colostrum ingredients after calving, when mammary gland activity is very intensive before the forthcoming lactation. Holstein-Friesian cows have been chosen for this research. The results obtained show that there are statistical values (P is less than 0.001) in concentration of the proteins, lipids, lactose, calcium, phosphorus, dry substances examined in colostrum of cows with one lactation, while another cows group with more lactation, between three and seven, concentrations of proteins, lipids and lactose are statistical values (P is less than 0.01), calcium, dry substances and pH are statistical values (P is less than 0.001), while concentration of phosphorus is on statistical value (P is less than 0.1). With compare those groups concentrations of phosphorus and pH are statistical values (P is less than 0.1), while concentration in proteins, lipids and lactose, statistical value is not proof.
