【目的】探索日粮不同粗蛋白质水平对乳鸽生长性能、屠宰性能、肉品质和种鸽产蛋性能的影响。【方法】选用健康、体质量和产蛋性能相近的180对种鸽,随机分为5个处理组,每个处理组6个重复,每个重复6对种鸽。5个处理组种鸽分别饲喂含粗蛋白质质量分数为15%、16%、17%、18%和19%的日粮,试验期包括种鸽产蛋期、孵化期、乳鸽哺育期和种鸽再产蛋期,共计1个生产周期。【结果】与其他处理组相比,饲喂18%粗蛋白质日粮组在乳鸽1~14日龄和1~21日龄平均日增质量均为最大,比15%粗蛋白质日粮组分别增加7．3%( P0．05)。试验期间,各处理组间种鸽的采食量和料质量比均未见显著差异(P>0．05)。与15%粗蛋白质日粮组相比,18%粗蛋白质日粮组乳鸽的全净膛率和胸肌率分别显著增加2．7%和6．4%( P0．05)；在种鸽哺育期间和乳鸽上市后1周内,18%粗蛋白质日粮组产蛋种鸽的比例最高(P0. 05 ) higher compared with the 15% crude protein group during 1 -14 days and 1-28 days respectively. The average feed intake and feed/gain ratio of breeding pigeons were not significantly different among groups. Compared with the 15% crude protein group, the eviscerated carcass rate and the percentage of breast muscle of squabs in the 18% crude protein group were increased by 2. 7% and 6. 4% (P0. 05 ) . During the feeding period of the breeding pigeons and within one week after the squabs went on the market, the 18% crude protein group had the highest percentage of laying breeding pigeons (P<0. 05). [Conclusion] Based on the comparisons and the quadratic regression analysis, the 18% crude protein group have good growth performance, carcass characteristics, meat quality of squabs and laying performance of breeding pigeons. The appropriate crude protein level for breeding pigeons dur-ing hatching and feeding period is 18%.
