Milk with a high somatic cell count is expected to have a lower content of what?

A high somatic cell count in milk is primarily an indicator of inflammation or infection in the udder, often stemming from mastitis. This condition can affect the health and productivity of dairy cows, leading to alterations in milk composition.

When somatic cell counts are elevated, one of the most significant changes observed is a reduction in casein content. Caseins are the main proteins in milk, and their concentration tends to decrease in response to the stress and inflammatory cytokines associated with a high somatic cell count. These proteins are crucial for the nutritional quality of milk and are also essential for cheese-making processes.

In contrast, while high somatic cell counts can impact fat, protein (total), and lactose levels in varying ways, the most notable and consistent decrease observed is in casein. This change can lead to poorer quality milk and affect its usability in dairy products.
