LOMILLOS PEREZ, Juan Manuel e ALONSO DE LA VARGA, Marta Elena. Osteochondrosis in fighting bulls and evaluation of its effect on the animal mobility. Rev. mex. de cienc. pecuarias [online]. 2017, vol.8, n.4, pp.453-462. ISSN 2448-6698. https://doi.org/10.22319/rmcp.v8i4.4301.
Osteochondrosis is a degenerative process of the joint surfaces. It is a disease of animal development widely described in the horse, with few references in cattle and virtually non-existent in the fighting bulls. The aim of this study was to record the prevalence of osteochondrosis in bulls and steers considering their possible causes and analysing the impact of this disease on the mobility of the animal during the fight. One hundred and twenty (120) fighting bulls, 3, 4 and 5 yr old fought at different bullrings were studied. During the dressing of cattle after fighting a macroscopic study of the carpal-metacarpal joint was performed, for studying the presence of injury in the joint faces involved and their severity. Alongside the fight, each animal was video recorded in order to analyse his mobility and evaluation of the falling syndrome. The results reflect articular cartilage damage in varying degrees in about 80 % of the animals studied, appearing in 63 % of cases on the medial aspect of the joint and mostly bilaterally. A negative influence was observed in the rate of falls expressed by the bull during the fight, and further research will be recommended and studies aimed at determining possible causes: nutritional alterations and inadequate training protocols.
