Heat Stress in Llamas and Alpacas
Llamas and alpacas, native to the cool, high-altitude mountains of South America, can be highly susceptible to heat stress in warmer, more humid climates as their thermoregulation mechanisms have become adapted to these cooler environments. Their dense fibre, an excellent insulator against cold, can become a significant liability as summer temperatures rise. For animal owners, understanding the science behind heat stress is not just about animal comfort; it’s critical for herd health, productivity, and survival.
