What physiological trait of Zebus helps with cooling efficiency compared to Bos taurus regarding surface area?
A greater surface area relative to body mass, aided by the dewlap
The Zebu cattle, scientifically classified as *Bos taurus indicus*, possess adaptations that enhance their survival in hot climates, notably through improved heat dissipation. A key structural feature contributing to this is the combination of their general body structure and the presence of a large dewlap, which is the flap of loose skin hanging from the neck. This configuration results in a greater surface area relative to the animal's total body mass when compared directly to *Bos taurus* breeds. This increased surface area-to-mass ratio is crucial because it allows for more effective transfer of internal body heat to the surrounding environment, significantly boosting overall cooling efficiency through convection and potentially radiation, complementing their specialized sweat gland activity.
