Background: The largest buffalo herd in Brazil is located on the Island of Marajó, in the State of Pará, northern Brazil. The pastures of the Island of Marajó consist of low quality graminaceous plants, which are generally poor in protein and mineral content. Unbalanced diets associated with low quality pastures are responsible for latent, sub-clinical diseases and metabolic disorders in bovines which affect bone health, especially in periods such as pregnancy and lactation. The purpose of this study was to point out and to describe the radiographic bone changes of buffalos with low body index bred in extensive system and intended for slaughter on the Island of Marajó, Brazil.Materials, Methods & Results: Radiographic examinations of anatomical pieces were obtained from 34 animals of buffalo species, with no distinction of gender, age, or breed. The animals were selected among those that were in the stockyard waiting for slaughtering for the obtainment of the anatomical pieces. For this selection, low physical condition was considered, which mainly included individuals with body condition indexes (ICC) of 1 and 2, on a scale of 1 to 5. From this selection, 98 anatomical pieces were obtained, which included: 28 sets of ribs, 20 femurs, 26 metacarpus, 7 mandibles, 3 radius and ulnas, 4 sets of vertebrae, 4 sets of metacarpus and phalanges, 1 tarsus and 1 set of tarsus and metatarsus. All the pieces were separated, identified, packed in plastic bag and forwarded to the radiographic study. At least one radiographic projection was obtained of each anatomical piece. These were identified, manually processed and stored for subsequent assessment. A single observer, in order to identify and to describe the bone radiographic changes, subjectively performed the radiographic assessment.[...](AU)
