Abstract
The performance of lactating cows is affected not only by ambient temperature but also by humidity. The effective temperature ET which emphasizes the importance of humidity is a useful index of heat stress level. The milk yield of Holstein cows which produce 20 kg/d begins to decrease above 22 ET and thus require suitable options to reduce heat stress to the cows. A nutritional management option is to feed gigh energy high rumen degradable protein containing diets to allow lactating cows to express their genetic potential in the tropics. In addition suficient water supply is necessary to promote feed intake and to dissipate body heat effectively as cows producing 25 kg/d have been shown to drink 90 L/d in the hot environment.
