This study evaluates the economic losses caused by lesions during shipping and pre-management in cattle slaughtered in Mato Grosso, Brazil. From 1,021 carcasses evaluated, 433 (42.4%) presented injuries caused hrough transportation and pre-slaughter management. Lesion frequency varied significantly with shipping times (P<0.05). Animals transported for up to 2 hours presented 1,82 lesion/carcass. In turn, animals transported 2 to 8 hours exhibited 2.05 lesion/carcass, what however did not differ statistically from the number of lesions in animals transported for more than 8 hours (2.07 lesion/carcass; P>0.05). Injured animals presented up to six lesions, although most (96.9%) had up to four lesions. Cattle transported for more than 2 hours presented more lesions than animals shipped for less than 2 hours (P<0.05). Most lesions were obsetrved on the loin (50.35% of lesions), followed by the rump (36.38%). Total weight loss of animals accounted for 115.76 kg, Annual economic losses in a midsized slaughterhouse were estimated at R$ 200,000 by lesions caused during transport and pre-slaughter management of cattle. |
