Key Points

The study aims to analyze the varying presence of somatic cells in cow milk and their implications for udder health.
Assessment of somatic cell types and physiological levels in cow milk.
Evaluation of somatic cell count as a diagnostic tool for udder health.
Identification of bacterial infections as a primary cause of elevated somatic cell levels.
Examination of environmental and genetic factors influencing somatic cell variation.
High somatic cell counts correlate with reduced milk yield and lower processing quality.
Diminished reproductive performance is associated with increased somatic cells.
Lactose concentration is highlighted as an effective indicator for monitoring somatic cell levels.

Abstract

Abstract This study analyses key aspects of somatic cells in cow milk. It outlines their types, physiological levels, and diagnostic value for udder health, particularly in detecting subclinical mastitis. Methods for determining somatic cell counts are presented, with bacterial infections identified as the main cause of elevated levels. The role of lactose concentration as a practical indicator is highlighted, alongside environmental and genetic factors influencing somatic cell variation in breeding practice. The consequences of high counts – such as reduced milk yield, lower processing quality, and diminished reproductive performance – are summarized. Finally, the study discusses hygiene prophylaxis measures and the role of somatic cell monitoring in dairy cattle improvement programs worldwide.
