Cells and enzymes composition of colostrum

Dynamics of the morphological picture of colostrum during the first five days of the postpartum period indicates the presence of immunologically active cells - macrophages, neutrophils, lymphocytes. The predominance of macrophages in colostrum with more pronounced phagocytic properties in comparison with neutrophils is shown. Cows of the Simmental breed have a higher content of epithelial cells in the colostrum and a higher rate of passage of the colostrum period when on the second day of lactation the content of the cellular elements in the colostrum is significantly reduced. It was found that newborn calves in the colostrum period are characterized by high adaptive abilities of the defense mechanisms, as evidenced by the consistently high indices of the OPF of blood neutrophils.
