Ease of Handling and Physiological Parameters of Stress Carcasses and Pork Quality of Pigs Handled in Different Group Sizes

摘要

The effect of different group sizes of pigs (3, 5, and 10 pigs) during handling on physiological parameters, carcasses, and pork quality traits at the farm and slaughterhouse were evaluated in 360 pigs. Ease of handling decreased as the group size increased. Moving pigs in smaller groups improve animal welfare parameters and carcass quality. However, meat quality classifications of the carcasses were not affected by the groups size used in preslaughter handling. Based on the results, moving groups of five pigs seems to be the best strategy to improve animal welfare and carcass quality.
