Study of the Physical and Chemical Composition of Colostrum of Simmental Cows as a Raw Material for Food Production

This article presents the results of research on the quality of milk of Simmental cows of Akmola region. Cow's colostrum contains a significant amount of biologically active substances, which makes it possible to use it in the technology of products of functional direction. As a result of the conducted researches it is established that chemical composition of cow's milk depends on the time elapsed from the moment of calving of cows. It was determined that the protein content in the colostrum collected on the first day after calving is three times higher than in the colostrum collected after 24 and 36 hours. Also, the content of solids in the milk of day 1 and day 2 was found to be high. Given the wide range of biologically active components, it is possible to develop specialised food products.
