title: Influence of dietary concentration and source of meat and bone meal on performance of turkeys.
abstract: Two experiments were conducted to determine the influence of dietary concentration and source of meat and bone meal (MBM) on performance of tom turkeys from 1 to 119 d of age. In Experiment 1, six replicate pens of toms were fed diets containing 0, 3, 6.5, or 10% MBM. Feeding up to 10% MBM resulted in 119-d BW and feed to gain ratios (F:G) equal to those of toms fed the diet containing no MBM (14.09 kg per tom, F:G = 2.68 for 10% MBM vs 14.08 kg per tom and F:G = 2.70 for the control). Five MBM were evaluated at 10% of the diet in Experiment 2. These MBM differed in source material and proportions of source material (beef, poultry, or pork processing by-products) from which they were made. As compared with feeding a diet containing no MBM, feeding diets with 10% of any of the MBM supported satisfactory 119-d BW and F:G. The data show that up to 10% dietary MBM obtained from different sources can be used successfully for growing turkeys when diets are formulated by using CP, amino acid, Ca, and P data for MBM obtained by laboratory analysis and the MEn value listed for MBM in NRC (1994).
