dc.description.abstractBackground: The largest buffalo herd in Brazil is located on the Island of Marajo, in the State of Para, northern Brazil. The pastures of the Island of Marajo 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 Marajo, 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. Discussion: Bone changes were remarkable and in animals of this study, reinforcing the nutritional aspect as being of great importance for the perfect mineral homeostasis and for the osteoarticular system maintenance. Consistent radiographic findings with osteopenia are most often related to nutritional disorders that affect bone metabolism, mainly involving the homeostasis of calcium (Ca) and phosphorus (P). The nutritional hyperparathyroidism, more commonly reported in dogs, cats and exotic animals is a common example of these affections, in which the bone radiopacity reduction is the most evident radiographic aspect. Copper (Cu) deficiency has been correlated with osteochondrosis, epiphyseal fracture of the femoral head and degenerative arthropathy of the hip joint, and erosion of the articular cartilage in a deer (Cervu selaphus). Degenerative arthropathy through radiographs was also found in this study. From the bone radiographic analysis, it is concluded that the osteodystrophic diseases of buffalos raised in pasture system on the Island of Marajo, Para, Brazil, present a variety of pathological conditions and the most commonly found were: osteoporosis characterized at the radiographic examination for the bone decreased radiopacity, change in bone trabeculae (medullary expansion) and cortical thinning, followed by pathological fractures with high incidence in the ribs. The low body condition, the underdevelopment and cachexia states of the animals in this study indicate the lack of an appropriate prophylactic conduct and a proper feed management. Therefore, the low reserves of P and Cu in the organism may have contributed to the osteoporotic process and, possibly, also to the protein-energy deficit, leading to secondary bone changes and causing a lack of productivity in the herd.pt_BR
