不同粗蛋白质、能量水平对肉鸽育肥期生长性能的影响

Effects of different Levels of crude Protein and Energy on Growth Performance of Pigeons in Fattening Period

选取1152只22日龄健康乳鸽随机分为8个组，研究肉鸽育肥期（22～30d）粗蛋白质为19％和20％2个水平，代谢能分别为11．91、12．12、12．33和12．54MJ／kg4个水平对其生长性能的影响；试验期9d。结果表明：各组间肉鸽平均日增重、平均体重差异不显著；粗蛋白质水平20％、代谢能水平12．33MJ／kg组的料重比最低，而粗蛋白质水平20％、代谢能水平11．91MJ／kg组料重比最高，且两组间差异显著；但其余各组间差异不显著。

1152 healthy young pigeons with age of 22 days were divided into 8 groups randomly to study the effects of crude protein levels 19% and 20% , metabolic energy levels 11.91, 12.12, 12.33 and 12.54 MJ/kg on the growth performance of pigeons in fatte- ning period ; the experiment lasted 9 d. The results showed that the difference of average daily weight gain and average body weight of pigeons between all groups was not significant ; the material - weight ratio in groups of crude protein level 20% and metabolic energy level 12.33 MJ/kg was the lowest, while the material -weight ratio in groups of crude protein level 20% and metabolic energy level 11.91 MJ/kg was the highest, and the difference between two groups was significant; however, the difference between other groups was not significant.
