Abstract
Reduction of dietary crude protein level has been recommended for broilers under
heat stress conditions, but low-protein diets have shown negative effects on performance. On
the other hand, high energy levels were suggested in order to dissipate the heat load during
panting. In this study it was investigated if birds would adjust their nutrient intake if they
were raised in a high temperature (HT) environment (31-32°C) as compared to a normal
temperature (NT) environment (21°C). It was found that feed intake, crude protein (CP)
intake, energy intake and body weight gain (BWG) were lower under the HT regime. CP
intake was lower in choice group whereas energy intake was higher. FCR of broilers in the
HT was lower than in the NT up to 35 d of age. Water consumption was more related to feed
intake rather than related to temperature.
