Abstract
Simple SummaryIn Uruguay, extensive, welfare-friendly beef production is a substantial part of the economy and culture. Transport of beef cattle to the slaughterhouse compromises animal welfare. The objective of this study was to assess transport conditions related to carcass bruising. A total of 242 trucks with 8132 animals were assessed on loading, transport, unloading conditions, and carcass bruising. In 39.3% of the loadings only a flag was used. The fastest unloading time was performed using a flag only. Carcass bruises were assessed by trained observers inside the plant. Although the number of bruises was high, there were no grade 3 bruises, the deepest and severe ones. It appeared that animal welfare training of truck drivers worked out well and the use of flags to move animals increased compared to a previous study in 2008.In Uruguay, extensive, welfare-friendly beef production is a substantial part of the economy and culture. Transport of beef cattle to slaughterhouse compromises animal welfare. The objective of this study was to assess transport conditions related to carcass bruising. A total of 242 trucks with 8132 animals were assessed on loading, transport, unloading conditions, and carcass bruising. Average loading time was 26 min and 21 s and the perception of the truck drivers was correlated with the time took for loading and the use of devices. In 39.3% of the loadings only a flag was used. The average unloading time was 5 min and 54 s with a significant difference in time for the use of devices; only flag 3 min 51 s, cattle prod 6 min 43 s and sticks 8 min 09 s. Of the carcasses observed, 772 (9.5%) had no bruises, 873 (10.7%) had one bruise, 1312 (16.1%) two, 1231 (15.1%) three and 3944 (48.5%) had four or more bruises. Prevalence of bruises were highest on the Tuber-coxea (hip) (29.3%) following forequarter (22.4%), Tuber-ischiadicum (rear) (17.3%), ribs/flank (14.1%), rump/round (10.1%) and loin (6.8%). Bruises were 68.7% grade 1 and 31.3 % grade 2; there were no grade 3, the deepest ones, observed. It appeared that animal welfare training of truck drivers worked out well and the use of flags increased compared to a previous study in 2008.
Highlights
In Uruguay, beef production is an important part of the economy
In the extensive production system used in Uruguay, which is generally welfare friendly, one of the most important stressors for cattle is the transport to the slaughterhouse [3]
Several initiatives, including activities focused on the impact of pre-slaughter conditions on beef cattle, have been carried out in Uruguay and in the region to promote animal welfare and improve meat quality [20,21]
Summary
In Uruguay, beef production is an important part of the economy. Worldwide product quality is crucial for the export position, and animal welfare is part of this condition [2]. In the extensive production system used in Uruguay, which is generally welfare friendly, one of the most important stressors for cattle is the transport to the slaughterhouse [3]. These animals are not used to being handled by humans and handling animals on farm, loading and unloading from vehicles, transportation, occasionally passing through livestock markets, and lairage can all affect their welfare [4]. Reducing physical and emotional stress during transport and associated events can improve both carcass quality and animal welfare [5]
