The Brahman breed is well-known for its exceptional tolerance to heat and strong resistance to insects. This breed originated in India and has developed physiological adaptations that allow it to thrive in hotter climates. Key features that contribute to its heat tolerance include a loose skin that helps with heat dissipation, a lack of undercoat, and a unique ability to sweat effectively. These traits make Brahman cattle particularly suitable for regions with high temperatures and humidity.

In addition to heat tolerance, Brahman cattle possess a resilient nature against various pests, including ticks and other insects, due to their thicker skin and natural defenses. These attributes not only enhance their survivability but also improve their overall productivity in challenging environments.

While breeds like Angus, Hereford, and Shorthorn have their strengths, they are generally less adapted to extreme heat or high insect pressures compared to Brahman cattle. This distinction makes the Brahman breed a popular choice in tropical and subtropical regions, where resilience to environmental stressors is crucial for effective cattle production.
