| dc.description | Carcass quality is one of the main parameters to evaluate broiler welfare, and the presence of back scratches indicates that the birds were submitted to stress. The objective of this study was to identify the best management practices during rearing and catching, taking into consideration broiler genetic differences (genetic lines A and B) and sexes. The survey was carried out in 351 broiler houses belonging to an integrated company and located in the region of Dourados, MS, Brazil. Between January and October, 2010, 2% of broilers of all ages (one to 43 days old) in all flocks were sampled. The sampled flock was evaluated in 21 d intervals. Scratches were classified as present or absent. The results indicated that catching management has the strongest influence on back scratches (73%), followed by rearing management (17%) and equipment management (10%). In general, strain A females presented the lowest probability of presenting scratches after weighing, equipment management, and catching. It was concluded that, although rearing and equipment management practices affected the presence of scratches, catching caused the highest percentage of lesions in birds of both strains, and therefore, it is considered critical. Broilers from distinct that genetic strains reacted differently to management practices due to their temperament and growth rate. Therefore, broilers should be housed according to genetic strain due to their different temperaments. | |
