This study presents revolutionary new approaches in animal husbandry, scientifically analyzing the factors affecting the concentration of immunoglobulins in the colostrum of newborn cows. Immunoglobulins (IgG, IgA, IgM) are the cornerstones of passive immunity of calves, and their proper provision directly affects their lives. The aim of the study is to identify numerous factors that determine the level of these immunoglobulins and to gain an in-depth understand­ing of the impact of this process on the development of calf health. By solving this problem, which scientists have been discussing for many years, the study sheds light on factors affecting the development of the immune system of newborn calves.
