Which physiological feature allows Zebu efficient evaporative cooling compared to European breeds?
Answer
Higher density of active sweat glands
A primary mechanism enabling Zebu to manage intense heat loads efficiently is their highly effective evaporative cooling system, which relies on a greater concentration of active sweat glands distributed across their skin surface. This increased density allows the animals to sweat more profusely than European cattle breeds, facilitating rapid heat dissipation through evaporation when environmental temperatures rise. Combined with their light-colored, short hair that reflects solar radiation, this physiological advantage is crucial for their survival and productivity in hot, humid tropical and subtropical zones.
