Radiographic study of the distal phalanx position and their possible correlation with obesity in patrol horses from the Military Police of Minas Gerais

With the aim to verify possible correlations between the spatial relationship between the distal phalanx and the hoof and signs of obesity, 55 horses from the Cavalry Regiment Alferes Tiradentes of Minas Gerais State Police - RCAT had x-rays taken from their thoracic hoofs. After that, horses were classified based on their subjective (body condition and neck scores) and objective (body mass index, neck circumferences, ultrasound measurement of fat tissue of the tail and on abdomen) methods for adiposity. Within the population, the body mass index showed that 52.6% of horses were overweight. Neck circumference at 50% of its dorsal length and ultrasound measurement of fat thickness on the insertion of the tail were the best objective methods. We identified specific radiographic characteristics of the population that were different from international parameters. Significant correlations among signs of obesity and measurements that indicate lamintis were found, suggesting association between these conditions in this horse population.
