The research was aimed at identifying the key characteristics of muscle and fat tissues when comparing two pig breeds: Black Sicilian pig and Landrace pig. In Psoas minor (Pm) and Psoas major (PM) muscles the morphometric characteristics of fibre types and their percentage were determined. The area of adipocytes from internal and external layer of adipose tissue was also determined. The results showed that slow twitch oxidative (SO) fibres were larger than fast twitch glycolytic (FG) and fast twitch oxidative glycolytic (FOG); Pm muscle was characterized by larger FG and SO fibres than PM; males had larger fibres than females in both muscles and breeds. Landrace pig has smaller adipocytes cells than Black Sicilian while Black Sicilian pig showed more essential fatty acids than Landrace. The results in favour of Black Sicilian pig show how conservation of animal biodiversity becomes important because of the high independent homeostatic capability exhibited by autochthonous genetic types for the management and control of the land.
