This study was undertaken to investigate the performance, carcass characteristics, and economic viability of diets including pasta waste in meal form (PWM) for quail. A total of 450 unsexed meat quail (Coturnix coturnix coturnix) were distributed into five treatments (0, 10, 20, 30, and 40% inclusion of PWM) in a completely randomized design with six replicates, each with 15 birds. The following rearing periods were evaluated: Phase 1 - 1 to 21 days; and period of 1 to 42 days. In Phase 1, the PWM levels did not influence feed intake (FI), and the PWM inclusion levels for optimal weight gain (WG) and feed conversion (FC) were estimated at 20.70% and 22.8%, respectively. In the cumulative period of 1 to 42 days, the PWM levels did not lead to differences in FI, WG, or FC. The yields of carcass and cuts were not influenced by the treatments; however, abdominal fat yield decreased as the PWM levels in the diets were increased. Economic analysis showed a reduction of the feeding cost in the studied phases. Pasta waste meal can be included up to the level of 40% without incurring losses in the performance or carcass yield of meat quail.
本研究旨在调查以粉状意大利面废料（PWM）为原料的鹌鹑日粮的性能、胴体特性和经济可行性。总共450只未分性别的肉鹌鹑（日本鹌鹑）被完全随机分配到五个处理组（PWM添加量分别为0%、10%、20%、30%和40%），每组六个重复，每个重复15只鸟。评估了以下饲养阶段：第1阶段——1至21天；以及1至42天的时间段。在第1阶段，PWM水平不影响采食量（FI），最佳体重增加（WG）和饲料转化率（FC）的PWM添加水平分别估计为20.70%和22.8%。在1至42天的累积期内，PWM水平在FI、WG或FC方面未导致差异。胴体和切块的产量不受处理影响；然而，随着日粮中PWM水平的增加，腹部脂肪产量下降。经济分析表明，在研究阶段饲料成本有所降低。意大利面废料粉的添加量可高达40%，而不会使肉鹌鹑的生产性能或胴体产量出现损失。
