In dairy cattle, which two factors can significantly influence milk quality?

Nutritional balance and stress levels are indeed critical factors that significantly influence milk quality in dairy cattle. A well-balanced diet is essential for optimal milk production, ensuring that cows receive the appropriate nutrients—such as proteins, fats, vitamins, and minerals—that contribute to milk composition and overall quality. When nutritional needs are not met, it can lead to poor milk quality, impacting both the flavor and the nutritional value of the milk.

Stress levels also play a vital role in milk quality. Cattle that experience high levels of stress—whether from environmental factors, handling techniques, illness, or social hierarchy within the herd—are likely to produce lower quality milk. Stress can lead to hormonal changes that affect milk production and composition, potentially resulting in increased somatic cell counts, which can indicate milk quality issues and contribute to udder health problems.

In summary, maintaining proper nutritional balance and managing stress levels are crucial for ensuring high milk quality, making these two factors central to effective dairy cattle management.
