Resumo
This study mapped cattle carcass lesions and associated the isoline maps with the occurrence factors of these lesions. Isoline maps were drawn by common kriging. The associated occurrence factors were the layout of the boards in the crowding tub (CT), characteristics of the hauling truck (general state and the presence of loose and/or sharp boards), broken boards in the corral (BBC), type of road covered (TRC), and animal falls upon unloading at the slaughterhouse (FAUS). The BBC showed a higher number of carcass lesions in the rib region. The data on FAUS and deterioration of hauling trucks fit an exponential model, with more carcass lesions in the rib and hindquarters, and plate regions, respectively. The data on spaced boards in the CT and TRC (mixed) showed greater carcass lesions in the rib region. Therefore, this method provides important information about the spatial distribution of lesions in bovine carcasses, and the drawing sheet used is adequate to represent such lesions.(AU)
