Abstract
HAMMOND (1941) found that 80 A.O.A.C. chick units of vitamin D per 100 grams of feed satisfied the requirements of growing poults. This is slightly greater than the requirements reported by Baird and Greene (1935) who concluded that 60 to 70 units of vitamin D per 100 grams of feed were required. Both of these reports show a much lower requirement of vitamin D than that reported by Jukes and Sanford (1939), who concluded that 200 A.O.A.C. chick units of vitamin D per 100 grams of diet was an approximation of the requirements of poults for the first four weeks.It was the purpose of this experiment to determine the vitamin D requirement for Broad Breasted Bronze turkey poults reared in confinement when fortified cod liver oil and activated animal provitamin D were used as sources of vitamin D.MATERIALS AND METHODSThree hundred day-old unsexed Broad Breasted Bronze turkey .
