Production responses to temperature and humidity index in lactating dairy cows
سال
: 2008
چکیده: One of the greatest challenges to production facing dairy farms in the north and north-east of Iran is heat
stress. Climatic conditions in this area are such that warm (or hot) season is relatively long, as generally there is high
relative humidity. Lactating dairy cows produce a huge quantity of metabolic heat. Heat produced and accumulated in the
body of dairy cows. The body temperature rises, intake declined and finally the cow’s productivity reduce as temperaturehumidity
index (THI) rise up. The purpose of this study was to determine the effect of THI on milk production and
constituents in the north-east of Iran.
