Why is climate considered in dairy cattle evaluation?

Climate is an essential factor in dairy cattle evaluation because it directly impacts cow comfort and health. Cows are sensitive to environmental conditions, and extreme temperatures—whether hot or cold—can significantly affect their well-being, productivity, and overall performance.

For instance, during hot weather, cows may experience heat stress, leading to reduced feed intake, lower milk production, and increased susceptibility to health issues. Conversely, in extremely cold conditions, energy is diverted from milk production to maintain body temperature, negatively affecting overall output. Therefore, understanding the climatic conditions where the dairy cattle are raised helps in evaluating their comfort levels and health, allowing for better management practices that can enhance productivity and welfare.

The other considerations, while important in dairy management, do not take precedence over the direct relationship that climate has with the comfort and health of the cows, which ultimately influences their productivity and the quality of milk produced.
