Egg Quality and Nutritional Profile of Three Sicilian Autochthonous Chicken Breeds: Siciliana, Cornuta di Caltanissetta, and Valplatani

The conservation of poultry biodiversity is a growing global priority, yet it necessarily relies on the scientific valorization of specific local breeds. This study aimed to characterize the lipid composition and cholesterol content of eggs from three native Sicilian chicken breeds (Cornuta, Valplatani, and Siciliana) reared under semi-extensive conditions, in order to evaluate their nutritional potential and support biodiversity preservation strategies. A total of 170 eggs from 11 farms were...
