Methionine, Choline, Fish Solubles and Milk in Rations for Growing Turkeys in Confinement ,

REARING of turkeys in confinement necessitates that dietary requirements be met without the aid of supplementary pasture grass which is provided under range conditions. It is obvious that a diet intended for confinement rearing should be more complete in both known and unknown nutrients than one intended for range rearing. It has been demonstrated that milk, choline, methionine, and fish solubles are beneficial supplements when added to certain diets fed to chickens or turkeys. This investigation was initiated to study the role of these nutritional ingredients in a practical ration for growing turkeys. The value of choline in promoting growth and preventing perosis of young turkeys has been amply demonstrated by Jukes (1940a, 1940b, 1941), Evans (1943), Patrick, Boucher, Dutcher and Knandel (1943), McGinnis (1946), and Slinger, MacIlraith and Evans (1946).
