Summary

Results of this study show that daily intake of dry matter (DM) and digestible energy (DE) was lower for the ‘warm’ environment and ‘high’ fibre groups. Efficiency of DM utilization was also lower for these groups. However, efficiency of DE was essentially the same for both rations, being lower in the ‘warm’ group. The lower intake in the ‘warm’ environment was attributed mainly to the longer length of time that animals spent resting, which resulted also in lower growth rates. The data indicate that increasing the caloric density of feed, to compensate for reduced consumption, would make it possible to obtain proportional increases in energy intake. As interactions were negligible, this situation would apply to both environments studied.
