Extract

1. The efficiency of food utilization for egg production by pullets has been determined for two diets, one high in energy and the other low.

2. Both groups laid at the same rate (245 eggs/bird) throughout the year.

3. Birds fed the low-energy diet ate more food, but the intakes of digestible protein, non-protein digestible energy and metabolizable energy were the same for both groups.

4. The cost of food perton was higher for the high-energy diet; per bird per year it was the same for both groups.
