T. Moran, K. K. Krueger, H. L. Stilborn] Two experiments were conducted with growing turkeys to compare the effectiveness of feeds having metabolizable energy (ME), crude protein (CP), and essential amino acids (EAA) at 110% of levels advocated by the NRC [1] with those at levels of 115%. AMEn measurements confirmed availability of associated energy while amino acid analyses verified minimum EAA contents. Although the increase in nutrient level from 110% to 115% of NRC [1] led to corresponding improvements in total feed conversion with both experiments, its realization during production was apparent only with rapid early growth and at finish. In one experiment, body weights of both males and females were marginally less from using the 115% regimen than 110%. In the other experiment, two strains of females grown to 16 wk had reduced gains from the 115% regimen early in development, but they recovered this loss at finish to be equivalent to those given the 110% regimen. High temperatures and humidities during experimentation together with extreme amount of dietary fat likely predisposed the reduced live weight gains when ME, CP, and EAA were at 115% of NRC [1] values. © 1995 Applied Poultry Science, Inc.
