The interplay between genetics and economics is important in understanding how crossbreeding can be harnessed to optimize sustainable poultry production, meat quality, and economic viability. This study was conducted to investigate the effect of crossbreeding on growth performance, meat quality, and production economics. A total of 451 unsexed day-old chicks were raised for 12 wk in a pure (Sasso X Sasso [SS]; Wassachie X Wassachie [WW]) and reciprocal cross (Sasso X Wassachie [SW]; Wassachie X Sasso [WS]) design. Data was collected on growth performance, meat quality, sensory evaluation, proximate analysis, and production economics. Genotype did not affect (P > 0.05) moisture, dry matter, ash, sensory evaluation, pH, and meat temperature. The carcass weights, final body weight, and cumulative weight gain of the hybrids were intermediate while the SS recorded the highest (P < 0.05) values. Drip loss between the WW and the reciprocal crosses was similar (P > 0.05) but lower (P < 0.05) than the SS genotype. Protein contents between the purebreds were similar likewise the crossbreds (P > 0.05). The SW cross recorded a higher (P < 0.05) lipid content compared to the WW cross while the WS recorded a higher (P < 0.05) protein content compared to the SS. The SS incurred higher feeding costs, and gross and net returns followed by the SW and then the WS with the WW having the lowest values. Crossbreeding improved growth performance, carcass traits, meat quality, chemical composition, and the gains in the crossbreds with the SW genotype having better results. The SW cross is recommended for better performance.
遗传与经济的相互作用对于理解如何利用杂交来优化可持续家禽生产、肉质和经济可行性非常重要。本研究旨在调查杂交对生长性能、肉质和生产经济的影响。总共 451 只未分性别的 1 日龄小鸡采用纯系（Sasso X Sasso [SS]；Wassachie X Wassachie [WW]）和正反交（Sasso X Wassachie [SW]；Wassachie X Sasso [WS]）设计饲养 12 周。收集生长性能、肉质、感官评价、近似分析和生产经济数据。基因型对水分、干物质、灰分、感官评价、pH 值和肉温没有影响（P > 0.05）。杂种鸡的胴体重、终体重和累计增重居中，而 SS 记录的数值最高（P < 0.05）。WW 和正反交之间的滴水损失相似（P > 0.05），但比 SS 基因型低（P < 0.05）。纯种之间的蛋白质含量相似，杂交鸡也是如此（P > 0.05）。与 WW 杂交相比，SW 杂交记录的脂肪含量更高（P < 0.05），而 WS 杂交记录的蛋白质含量更高（P < 0.05）比 SS。SS 鸡的饲料成本较高，总收益和净收益次之，然后是 SW 鸡，而 SS 鸡的收益最低。杂交提高了生长性能、胴体性状、肉质、化学成分，并且 SW 基因型的杂种具有更好的结果。SW 杂交推荐用于获得更好的性能。
