No recent studies with turkeys have shown vitamin E requirements in diets in different rearing stages. The NRC [24] suggests 10 mg of vitamin E/kg of diet for broiler chickens during the rearing period and 12 mg of vitamin E/kg
of diet for turkeys at the initial phase. In some cases, however, vitamin E levels 20 to 25 times greater than the requirements suggested by the NRC [24] are used in industry. According to Félix et al. [25], fat-soluble vitamin
levels are the most variable ones recommended by the NRC [24] and used by the poultry industry. This is due to the involvement of fat-soluble vitamins with the development and maintenance of tissue structure, immunity, and
improved meat quality.
