A rise in which milk measurement is commonly used as an indicator of subclinical mastitis in dairy cattle?
Correct answer: A. Milk somatic cell count
- A. Milk somatic cell count
- B. Milk lactose concentration
- C. Milk urea concentration
- D. Milk freezing point
Explanation
Mammary inflammation commonly increases the milk somatic cell count, even when visible changes in milk or the udder are absent. Lactose often decreases during mastitis, while urea and freezing point are not the primary screening measures for this condition.
