Abstract

|
|
|
In a trial involving 130 pigs, the effect of mixed-gender(gilts 50% + barrows 50%), gilts and barrows groups transportation on pig behaviour, skin damage of carcass, muscle pH and color were investigated. They were transported for on average 1hr 30 min from the farm to a slaughter house, and held in lairage for 1hr. Stocking density during transport was 0.4㎡ per 110㎏ live weight, and population density in lairage was 0.7㎡. The percentages of standing pigs were high for gills and low for barrows during their transport. The percentage of sitting or lying pigs were high for barrows during (heir transportation. The muscle pH and meat color were not significantly (p$gt;0.05) different among the mixed gender, gilts and castrates transportation. The skin damage scores of carcasses were significantly (p$lt;0.05) lower in mixed sex transportation than those in the transportation of gilts and castrates.
