Livestock Industry Facilities And Environment: Heat Stress Indices For Livestock, Hongwei Xin, Jay D. Harmon Mar 1998

Livestock Industry Facilities And Environment: Heat Stress Indices For Livestock, Hongwei Xin, Jay D. Harmon

Agriculture and Environment Extension Publications

Heat stress indices (HIS) combine the effects of both temperature and relative humidity, and are classified into alert, danger, and emergency zones. Because different animal species and humans have different sensitivities to temperature and relative humidity, the heat stress charts are thus unique of that particular species.
