Other environmental adaptations which make the Brahman breed so well suited to so many areas of the country include the ability to utilize lower-quality feed, to travel longer distances for feed and water, and to resist insects and external parasites while withstanding vast climactic differences. They also have the ability to reproduce on a regular basis in a stressful environment.
Brahman cattle show no effect from extremely high temperatures.
A factor which contributes to the Brahman's unique ability to withstand temperature extremes is a short, thick, glossy hair coat which reflects much of the sun's rays, allowing them to graze in midday sun without suffering. In severe winters, Brahmans grow a protective covering of long, coarse hair beneath which a dense, downy, fur-like undercoat can be found. F. Above 70 degrees F European cattle decline in appetite and milk production. F. An abundance of loose skin, characteristic of the breed, also aids in its ability to withstand warm weather by increasing the body surface area exposed to cooling. In cold weather the skin is contracted, increasing the thickness of the hide and density of the hair, which aids in retaining body heat.
