Abstract

The existing experiment was intended to explore differences among three breeds of duck, Molar, White Pekin, and Brown Iraqi local duck, in carcass traits and some organs. Thirty ducks (n= 10 of each breed) were reared at age 2 months in an open scheme for 8 weeks. At the end of this period, before and after slaughter, the weight of all ducks had taken. The carcass, thighs, back and neck, wings, and breast were estimated by balance. Then, some slaughter organs, heart, liver, and gizzard were weighed. The statistical analysis of current data showed a significant (P≤0.05) raising in live body weight (LBW) in molar ducks compared with other breed ducks. On the other hand, the results of carcass traits recorded a significant (P<0.05) increment in wings percentage in molar ducks compared with White Pekin and Brown Iraqi local ducks. Also, the statistical examination verified a significant (P<0.05) increment in heart and gizzard percentages in molar ducks compared to other breeds. The regression equations were also verified for determining live body weight by slaughter traits in three breed ducks. Concluded that there are differences among Molar, Pekin, and Brown Iraqi local ducks in live body weight and carcass weight, as well as weights of some organs; also improved significantly in Molar ducks comparison with White Pekin and Brown Iraqi local ducks. Keywords: Ducks; slaughter; breed.

研究胴体的差异以及摩尔鸭、白京鸭和褐伊本地鸭胴体各部分的相对重量。

现有实验旨在探索摩尔鸭、白京鸭和褐伊本地鸭三个品种在胴体性状和某些器官方面的差异。30 只鸭子（每个品种 10 只）在 2 个月大时在开放式计划中饲养 8 周。饲养结束后，在屠宰前和屠宰后测量所有鸭子的体重。用天平估算胴体、大腿、背部和颈部、翅膀和胸部的重量。然后，对一些屠宰器官、心脏、肝脏和胗进行称重。对当前数据的统计分析表明，臼齿鸭的活体重（LBW）与其他品种鸭相比有显著提高（P≤0.05）；另一方面，胴体性状结果表明，臼齿鸭的翅膀百分比与白皮鸭和伊拉克褐鸭相比有显著提高（P<0.05）。此外，统计检查还证实，与其他品种的鸭子相比，臼齿鸭的心脏和胗百分比有显著提高（P<0.05）。还验证了通过屠宰性状确定三个品种鸭子活体体重的回归方程。结论：臼齿鸭、北京鸭和伊拉克褐土鸭在活体重量、胴体重量以及某些器官的重量方面存在差异；臼齿鸭与白色北京鸭和伊拉克褐土鸭相比也有显著提高。关键词鸭；屠宰；品种
