Abstract

Data from three separate feedlot finishing trials were combined into one data set to determine wind speed and solar radiation adjustments to the temperature- humidity index equation based on degree of panting and ambient environmental conditions. Regression equations were used to determine the relationship between observed panting and current temperature-humidity index, wind speed and solar radiation for developing correction factors. Based on these calculations, for each 1 mile/ hour increase in wind speed, THI should be decreased approximately 1 unit, and for each 3 Langley increase in solar radiation or 10% increase in cloud cover, THI should be decreased approximately 1 unit.
