The aim of the study was to compare Muscovy ducks and mule ducks for proximate analysis, colour attributes, sensory properties of the meat, and concentration of some minerals in the meat and liver, with consideration of the effect of sex on the analysed traits. The study used 46 Muscovy and 44 mule ducks. At the end of the rearing period, 40 birds (10 males and 10 females of each genotype) were selected for slaughter. Meat and liver samples were collected from the slaughtered birds to determine quality traits. The analysed ducks of different genotypes differed significantly in the water content, sodium content, and redness of breast muscles; in the water, fat, and zinc content of leg muscles; and in the sodium, iron, and copper content of liver. Regardless of genotype, males had a higher sodium content in breast muscles; contained more protein, sodium, phosphorus, and magnesium and less potassium and copper in leg muscles; and had a significantly higher content of sodium, potassium, phosphorus, magnesium, zinc, iron, and copper in liver compared to females. The genotype-sex interaction was significant for the sodium and potassium content of breast muscles, for the water, protein, sodium, potassium, phosphorus, magnesium, and copper content of leg muscles, and for the copper content of liver. Our study provided information about differences in the quality of meat and liver in Muscovy and mule ducks.
本研究的目的是比较番鸭和半番鸭的近似分析、颜色属性、肉的感官特性以及肉和肝脏中某些矿物质的浓度，并考虑性别对所分析性状的影响。该研究使用了46只番鸭和44只半番鸭。在饲养期结束时，挑选40只鸟（每种基因型的雄性和雌性各10只）进行屠宰。从屠宰的鸟身上采集肉和肝脏样本以确定质量性状。不同基因型的分析鸭在胸肌的含水量、钠含量和红色度；腿肌的水、脂肪和锌含量；以及肝脏的钠、铁和铜含量方面存在显著差异。无论基因型如何，雄性胸肌中的钠含量较高；腿肌中含有更多的蛋白质、钠、磷和镁，而钾和铜含量较少；与雌性相比，肝脏中钠、钾、磷、镁、锌、铁和铜的含量显著更高。基因型与性别的交互作用在胸肌的钠和钾含量、腿肌的水、蛋白质、钠、钾、磷、镁和铜含量以及肝脏的铜含量方面具有显著性。我们的研究提供了有关番鸭和半番鸭肉和肝脏质量差异的信息。
