In the two experiments on restricted feeding of broilers there were no interactions between dietary nutrient concentration and access time to food on either performance or carcass characteristics. 2. In the first experiment (winter), food denial for 8 h/d improved food conversion efficiency and increased dressing percentage. Increasing nutrient concentration increased growth rate; decreased food intake; and improved conversion efficiency. 3. In the second experiment (summer), food denial for 8 h/d tended to increase growth rate and to improve conversion efficiency, but not significantly. Increasing nutrient concentration had the same effect as in experiment 1. 4. It is concluded that restricted access to food generally improves food efficiency.
