Abstract

This study sought to evaluate the number of bruises on bovine carcasses and their relationship with loading rates in different truck models. Bruising percentages in the hindquarter, forequarter and short rib regions were evaluated. The space occupied on the truck by each animal in m2 was defined as the Practiced area, obtained by dividing the body area by the number of males and females transported in straight trucks (10.60 × 2.40 m) and livestock trailers (14.80 × 2.60 m), 240 and 168, and 120 and 93, respectively, and 80 males in a straight truck with trailer configuration (17.50 × 2.60 m). The minimum area occupied by the animals was assessed according to the Farm Animal Welfare Council (FAWC) and Animal Welfare Advisory Committee (AWAC). The data was analyzed in a completely randomized design and included two se× classes, three carcass regions and three truck types. For males, the minimum areas (m2) calculated by the FAWC and AWAC were smaller (1.37 and 1.29 m2, respectively) for the straight truck. The straight truck with trailer configuration had the lowest (P=0.0025) bruising inde× in the forequarter region (15.1%) and the highest (P=0.047) in the short rib region (30.5%). Females transported in the livestock trailer had a higher (P<0.001) percentage of bruises in the forequarter region (51.7%). There was a relationship between the high bruising rates and the loading rate Practiced for the males. Estimations made by the AWAC are close to those practiced in the upper Pantanal region of Mato Grosso do Sul, Brazil.
