Effects of certain risk factors on presence and severity of carcass bruising in cattle: A study in Turkey.

The aim of the study was to examine the effects of some pre-slaughter factors on the total carcass bruise severity score and the presence of carcass bruises. Bruises on 1027 cattle carcasses were evaluated with the "The Australian Carcass Bruise Scoring System," and at least one bruise score was determined in 92.7% of the carcasses. The total carcass bruise severity score increased as the animal's age, transport time, and AWACT (the Welfare Impact Score of Stockperson Actions) score increased (P < 0.001). The probability of the presence of carcass bruising increased 2.751 times in the autumn (P = 0.031) and 2.200 times in the summer (P = 0.072) compared to the winter. Carcass bruises tended to be 1.747 times more common in females than males (P = 0.065), and 65.9% less in the Simmental than Brown Swiss breed (P = 0.060). Human contact (OR = 1.685; P = 0.079) and electric goad using (OR = 1.762; P = 0.069) on the slaughter corridor tended to increase the probability of the presence of carcass bruises. In conclusion, to reduce the presence and severity of carcass bruises, it may be beneficial to focus on the improvement of handling and coercion practices applied by the stock person, to slaughter the cattle in the nearest slaughterhouse, and to pay more care to the handling of culled cattle.
