title: Performance and energy needs of 20-week-old male turkeys at different environmental temperatures.
abstract: Performance of male 20-week-old B.U.T. turkeys at different environmental temperatures was evaluated. Weight gain was severely depressed by a constant 35 C but was also lower at 27 C than at 10 and 20 C. Feed efficiency hardly changed between 10 and 20 C but was depressed at the higher temperatures. The calculated energy needs for maintenance were only slightly reduced at 20 C compared with 10 C, but they declined continuously with an increase in temperature up to 35 C.
