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).
进行了两项试验，以确定日粮中肉骨粉（MBM）的浓度和来源对1至119日龄公火鸡生产性能的影响。在试验1中，将六组公火鸡饲养在重复栏中，分别饲喂含有0%、3%、6.5%或10%肉骨粉的日粮。饲喂高达10%肉骨粉的公火鸡119日龄体重和料重比（F:G）与饲喂不含肉骨粉日粮的公火鸡相同（每只公火鸡14.09千克，10%肉骨粉组的F:G = 2.68，对照组每只公火鸡14.08千克，F:G = 2.70）。在试验2中，评估了五种肉骨粉，其添加量均为日粮的10%。这些肉骨粉的原料来源和原料比例（牛肉、家禽或猪肉加工副产品）不同。与饲喂不含肉骨粉的日粮相比，饲喂含有10%任何一种肉骨粉的日粮，公火鸡119日龄体重和料重比均令人满意。数据表明，当根据实验室分析获得的肉骨粉粗蛋白、氨基酸、钙和磷数据以及NRC（1994）中列出的肉骨粉代谢能值来配制日粮时，日粮中高达10%的不同来源肉骨粉可成功用于火鸡生长。
