These samples were analysed chemically. The gross composition and some minerals constituents were determined, tabulated and discussed. The average values of the determined chemical constituents except both of pH value and lactose decreased gradually (titratable acidity, specific gravity, fat, T.S, S.N.F, T.P., casein and ash). Also, the minerals compositions of these two types of colostrum (cow and buffalo): Ca, K, Na, P, Zn, Mg and Mn gradually decreased during the first seven days of lactation period. Introduction Colostrum is pre-milk substance that is produced immediately with the first days after birth. Colostrum is thick lemon yellow mammary secretion. It is considered as a vital food for the newborn of all mammals, due to its high contents of transfer immunity factors as immunoglobulins, in addition to its nu...
