Extract

1. The behaviour of six grade and six zebu steers in a temperate environment was compared with their behaviour when moved to a tropical climate.

2. Reaction of both groups to the heat was demonstrated by seeking shade, increased water consumption and an alteration of grazing times. The similarity in their behaviour was, however, the most striking feature. The grades lay down slightly longer than the zebus, but showed no other differences and were not apparently distressed by heat.

3. The greatest difference found was in ruminating times and it is suggested that differences in food conversion may be more important than differences in heat tolerance, provided the animals are given the opportunity to adapt themselves fully to their environment.
