CHANGES IN THE PHYSICOCHEMICAL COMPOSITION OF RAW MILK AS A RESULT OF INCREASED SOMATIC CELL COUNT

Abstract

This study aimed to assess the impact of an elevated somatic cell count (SCC)—a key indicator of udder health and milk quality—on the physicochemical composition of 4,287 raw cow milk samples collected from three dairies. As SCC levels increased, significant changes were observed in lactose and protein content, freezing point, and solids non-fat, with lactose exhibiting the most pronounced variations. These findings highlight the direct influence of SCC on milk composition, reinforcing the importance of strict hygiene practices in dairy farms to ensure optimal milk quality and safety.
