ABSTRACT
For almost six months out of every year the temperature in Kuwait rises above the comfortable temperature for dairy cattle. Every year milk production and reproduction efficiency of dairy cows in Kuwait decrease in the summer, due to heat stress conditions.
From the several indices which have been developed to predict comfort and discomfort of environmental conditions, the temperature-humidity index (THII is used in this study. It was found that only 44% of the year lies in the recommended comfortable levels of THI. For the rest of the year the values of TTHI are higher than the comfort level and heat stress conditions exist.
