The slaughter performance and meat quality of two native Italian chicken breeds, (BP, = 64) and (BS, = 64), were investigated. Two-way ANOVA, considering breed, sex, and their interaction, was used to compare the properties of birds slaughtered at 5, 6, 7, and 8 months of age. Subsequently, data were analyzed using one-way ANOVA and the Duncan test to evaluate the differences between slaughter ages. The BP breed produced a better carcass yield than BS at 5, 7, and 8 months of age ( < 0.05). Breast moisture and crude protein contents were influenced by gender, and were higher in males than in females ( < 0.05). By contrast, the crude fat content was higher in females than in males ( < 0.05). The saturated fatty acid content of breast meat increased as the birds aged in both breeds ( < 0.05). The polyunsaturated fatty acid content of both breast and thigh meat was higher in males than in females ( < 0.001 and < 0.05, respectively). In general, slaughtering at 7 months was associated with the best slaughter and meat quality characteristics in both breeds. Moreover, from a nutritional point of view, the characteristics of the meat from male birds were preferable to those of meat from females.
对两个意大利本土鸡品种(BP,n = 64)和(BS,n = 64)的屠宰性能和肉质进行了研究。采用双向方差分析,考虑品种、性别及其相互作用,比较5、6、7和8月龄屠宰鸡的特性。随后,使用单向方差分析和邓肯检验分析数据,以评估屠宰年龄之间的差异。BP品种在5、7和8月龄时的胴体产量高于BS品种(P < 0.05)。胸肉水分和粗蛋白含量受性别影响,雄性高于雌性(P < 0.05)。相比之下,雌性的粗脂肪含量高于雄性(P < 0.05)。两个品种的胸肉饱和脂肪酸含量均随鸡龄增长而增加(P < 0.05)。雄性胸肉和大腿肉的多不饱和脂肪酸含量均高于雌性(分别为P < 0.001和P < 0.05)。总体而言,7月龄屠宰与两个品种最佳的屠宰和肉质特性相关。此外,从营养角度来看,雄性鸡肉的特性优于雌性鸡肉。
