Effects of temperature–humidity index on health and growth performance in Japanese black calves

This study evaluated the relationship between the temperature–humidity index (THI), health and growth performance of Japanese black calves, by reviewing health data collected from nearly 20,000 calves and 60,000 markets weights. Data showed that Japanese black calves are susceptible to a cold environment immediately after birth, leading to lower body weight gain, and also that they are susceptible to a heat in the environment three months after birth. Managing the environmental exposure of Japanese black calves at birth and during growth will lead to optimal health and performance.
