| Abstract: | The vitamin A requirement of Broad Breasted White turkey poults from o to 12 weeks of age is at least 2670 i.u. vitamin A/kg and possibly ranges between 2670 and 4721 i.u. vitamin A/kg. The vitamin A stored in the liver of the turkeys fed 4721 i.u. vitamin A/kg was significantly greater than those fed 1034 to 2670 i.u. vitamin A/kg at 4, 8 and 12 weeks of age. The average weights of the birds at 4, 8 and 12 weeks of age were significantly greater when the diet was supplemented with 4721 i.u. vitamin A/kg. |
