Gender had strongest influence on carcass bruising, being first variable enter in majority models related sites. Female carcasses displayed higher all Densities above 401 kg/m² caused more bruising. With exception unacceptable, acceptable assigned farm resulted average Articulated vehicles with a greater capacity likely cause The effects causing act differently various In this sense, results suggested possible management practices specific problems during period minimize losses by different
