Abstract

Male and female Large White Nicholas turkeys were fed corn and soybean meal diets for 24 and 20 wk, respectively. Control and low protein (75% of control in protein and 66% of control in lysine and methionine) diets were fed during 0 to 6 wk of age. Thereafter, both groups received the control diet. Body composition of turkeys was determined at 0, 2, 4, 6, 8, 12, 16, 20, and 24 (males), and at 0, 2, 4, 6, 8, 11, 14, 17, and 20 (females) wk of age. Compared with controls, undernourished turkeys had depressed body weight gain, lower feed intake, poorer feed efficiency, reduced carcass protein, increased carcass fat, and better efficiency of protein retention at 6 wk of age. During realimentation (after 6 wk of age), undernourished turkeys increased average daily feed consumption to that of controls and showed increased weight gains. By 24 and 20 wk of age, weights of undernourished male and female turkeys were no longer different from the weights of their respective controls. Feed efficiency of undernourished turkeys was better than that of controls during realimentation. Differences in body composition of undernourished and control turkeys were no longer evident after realimentation.
