What is the common implication of a somatic cell count over 400,000?

A somatic cell count (SCC) over 400,000 is a significant indicator of potential mastitis in dairy cows. Somatic cells, primarily white blood cells, increase in response to inflammation or infection in the udder, such as occurs with mastitis. When the SCC is elevated, it suggests that the cow's immune system is responding to an infection, which can compromise milk quality.

High SCC can lead to decreased milk quality and safety, as elevated somatic cell counts may affect the milk’s taste and shelf life. Furthermore, milk from cows with high SCC is often downgraded, which can contribute to lower milk prices for the producer. Monitoring SCC is essential for maintaining herd health and ensuring that the milk produced meets quality standards. Therefore, an SCC over 400,000 primarily indicates the risk of mastitis, necessitating management practices that focus on cow health and mastitis prevention.
