Estudo da correlação de medidas radiográficas indicadoras de laminite em éguas da raça Mangalarga Marchador com e sem sinais de sobrepeso (Correlation study about radiographic measurements signaling laminitis in Mangalarga Marchador mares with or without signs of overweight)
2014
The radiographic evaluation of the hoof is essential in the diagnosis and follow-up of equine laminitis; however, few studies have been conducted in Brazilian breeds. The aim was to perform the morphometry of radiographic images taken from the digit of Mangalarga Marchador in order to obtain a profile of measurements indicative of laminitis in this population. We also compared measurements form mares without (body score 5 and 6) and with (body score 7 and 8) signs of overweight. There was no significant difference between measurements from the two groups (P> 0.05), but there was significant positive correlation between founder distance and signs of adiposity in the neck and in the base of the tail. Findings from this study demonstrate that radiographic morphology of the hoof from this population of Mangalarga Marchador mares differ from standard international reference values. Furthermore, in this group of mares, those with body condition grading 7 and 8 did not seem to be more prone to develop laminitis, since there was no difference when they were compared with mares showing lower grades. However, a significant correlation among founder distance and signs of adiposity in the neck and base of tail indicate that Mangalarga Marchador mares are also prone to obesity-associated laminitis.
