The valorization of agro-industrial byproducts in domestic animal feed has the potential to reduce the cost of animal production. This trial was conducted to determine the effect of incorporating prickly pear byproducts (envelopes and cakes) as a partial substitute for corn and soybean meal in the diet of wheat quails (Coturnix coturnix) during their rearing period. Six hundred-day-old Coturnix coturnix quails of equal sex ratio (1:1), weighing on average 7 ± 0.5 g, were randomly distributed into four groups, one control group and three experimental groups, according to the rates of incorporation of prickly pear cakes and envelopes, in sequential or nonsequential mode, in the different rearing phases. Each batch (150 subjects) was subdivided into five packs of 30 animals and randomly distributed according to the rate of incorporation (0%, 10%, 20% and 30%) of prickly pear envelopes and cakes. The live weight at 45 days and average daily gain (ADG) increased significantly with the introduction of byproducts in all rearing phases (SF). The carcass yield increased significantly (p < 0.05) with the introduction of byproducts in the finishing phase (F) and in all rearing phases (SF). The mineral content decreased significantly (p < 0.05) in all the experimental groups. The protein content increased significantly by 2 points on average when the two prickly pear byproducts were introduced in all rearing phases. The blood biochemical profile of each experimental batch was not influenced by the incorporated prickly pear byproducts. Prickly pear envelopes and cakes in wheat quail feed improve growth performance and meat quality, particularly when they are introduced in the finishing phase and in all rearing phases.
农产品加工副产品在动物饲料中的高值化利用具有降低动物生产成本的潜力。本试验旨在研究在育雏期（60 日龄）小麦鹧鸪（Coturnix coturnix）日粮中用仙人掌副产物（包膜和饼）部分替代玉米和豆粕对其生长性能的影响。采用雌雄比例 1:1、平均体重 7±0.5g 的 600 日龄小麦鹧鸪 600 只，随机分为 4 组，1 个对照组和 3 个试验组，按照包膜和饼的添加比例（顺序或非顺序），在不同育雏阶段进行分组。每组（150 只）再分为 5 个 30 只鸡的重复，根据包膜和饼的添加比例（0%、10%、20%和 30%）随机分配。45 日龄活重和平均日增重（ADG）在所有育雏阶段（SF）均随着副产物的添加而显著增加。随着副产物在育肥阶段（F）和所有育雏阶段（SF）的添加，屠体产率显著增加（p<0.05）。所有试验组的矿物质含量均显著降低（p<0.05）。当两种仙人掌副产物在所有育雏阶段添加时，蛋白质含量平均提高了 2 个百分点。每个试验批的血液生化指标不受添加的仙人掌副产物的影响。仙人掌包膜和饼在小麦鹧鸪饲料中可改善生长性能和肉质，特别是在育肥阶段和所有育雏阶段添加时效果更佳。
