Summary

Three experiments were conducted to assess the effects of different protein and energy levels on turkeys during the periods 12–16 weeks, 16–20 weeks and 20–24 weeks. Compared with 20 and 22% protein, 18% significantly depressed weight gain and feed efficiency during the 12–16 weeks period, while 14 and 16% protein, compared with 18%, significantly depressed weight gain and feed efficiency during the 16–20 weeks period but gave similar weight gain and feed efficiency as the 18% protein during the 20–24 weeks period.

During all periods between 12 and 24 weeks, the two energy levels tested (11·72 and 12·56 MJ/kg) did not significantly affect weight gain and feed efficiency whereas feed consumption was significantly higher on the lower energy level.

The present studies suggest that 20, 18 and 16% protein, all with metabolizable energy of 11·72 MJ/kg, may be recommended for turkeys aged 12–16 weeks, 16–20 weeks and 20–24 weeks respectively.
