Metabolizable Energy Determinations of Safflower Meals for Turkeys

Metabolizable energy determinations were made with turkeys during the fourth week of age on decorticated (42% protein) safflower meal by two methods: total collection of feces and use of a fiber tracer. The nitrogen-corrected metabolizable energy content of the decorticated safflower meal by the total collection method on a dry basis was 1.75 kcal./gm., and by the fiber tracer technique 1.63 kcal./gm. The average of these two values was 1.69 kcal./gm. Metabolizable energy determinations were made with undecorticated (20% protein) and decorticated safflower meals with turkeys using the fiber tracer method during the fourteenth week of age. The nitrogen-corrected metabolizable energy values on a dry basis were: undecorticated safflower meal, 1.75 kcal./gm., and decorticated meal, 2.24 kcal./gm.
