An experiment was conducted to determine the effects of dietary protein and added fat on body weight, feed consumption, and feed efficiency of male and female Nicholas Large White (N), Jaindl Large White (JL), and Jaindl Medium White (JM) turkeys at various ages. At 8 wk of age, 162 males and 288 females from each strain were divided equally into six pens of males and six pens of females per strain. Each of 6 pelleted diets containing standard or high protein and 0, 5, or 10% added fat was fed to one pen of each sex and strain of turkeys. At 20 wk of age, N, JL, and JM males weighed 14.77, 11.56, and 9.00 kg, respectively, and females weighed 8.97, 7.49, and 5.75 kg, respectively. At 28 wk of age, N, JL, and JM males weighed 18.32, 15.10, and 11.65 kg, respectively, and females weighed 10.35, 9.12, and 7.04 kg, respectively. The feeding of diets containing 10% rather than 0% added fat from 8 to 20 wk of age decreased feed consumption 11.1 and 13.1% and increased feed efficiency 16.3 and 16.4% in males and females, respectively. Feeding high protein diets significantly increased body weight gains. The apparent smaller increase than previously experienced in feed efficiency from dietary added fat may be associated with the use of pelleted feed in this experiment. |
