In poultry production, the intensive use of high-performing hybrid animals led to loss of genetic variability and a consequent lower response to climatic change and disease. Poultry biodiversity is seriously threatened, and its safeguard is a strong objective in developed countries. According to the FAO, which emphasized the importance of native breeds for its country of origin, the aim of this study was to present the first contribution on eggs quality for endangered the Siciliana chicken breed and deepen knowledge on the local Livorno breed. At 20 weeks of age, 108 laying hens (54 Siciliana breed and 54 Livorno breed) were divided into six homogeneous groups of 18 hens each and reared according to requirements imposed by the EC Regulation 889/08 for organic production. The production cycle was controlled over one year, and egg production was recorded daily by group. Eggs were collected, weighted, and measured. Physico-chemical parameter and fatty acids profile were analyzed and nutritional indexes calculated. The statistical model included the effects of breed (Siciliana, Livorno). Egg production was 190 egg/head for Siciliana and 180 for Livorno group. The results showed similar values for Siciliana and Livorno egg quality, highlighting several valuable quality traits from these breeds which might be taken into account for conservation programs.
在家禽生产中，高性能杂交动物的密集使用导致了遗传变异性的丧失，进而降低了对气候变化和疾病的应对能力。家禽生物多样性受到严重威胁，在发达国家，保护家禽生物多样性是一个重要目标。根据强调本地品种对其原产国重要性的联合国粮食及农业组织（FAO）的说法，本研究的目的是首次对濒危的西西里纳鸡品种的蛋品质做出贡献，并加深对当地里窝那鸡品种的了解。在20周龄时，108只产蛋母鸡（54只西西里纳品种和54只里窝那品种）被分成6个每组18只母鸡的同质组，并根据欧盟法规889/08对有机生产的要求进行饲养。生产周期控制了一年，每天按组记录产蛋量。收集鸡蛋，称重并测量。分析了理化参数和脂肪酸谱，并计算了营养指标。统计模型包括品种（西西里纳、里窝那）的影响。西西里纳组的产蛋量为每只鸡190枚蛋，里窝那组为180枚。结果显示，西西里纳鸡蛋和里窝那鸡蛋的品质值相似，突出了这些品种的几个有价值的品质特征，这些特征在保护计划中可能会被考虑。
