In a trial involving 172 pigs, the effects of transport stocking densities of 0.3, 0.4 and 0.5㎡/per 110㎏ pig on blood profile, skin damage of carcass, muscle pH and color were investigated. The pigs came from a fawn and were transported by six times. They were transported for on average 1hr 30 min from farm to slaughter house, and held in lairage for lhr. Blood profile including cortisol, β-endorphin, glucose and lactate dehydrogenase was not significantly (p$gt;0.05) different among al! stocking densities. However, the Creatine phosphokinase (CPK) level of a stocking density of 0.3㎡ was significantly (p$lt;0.05) higher than those of other stocking density groups. This result suggested that higher transport density resulted in more physical stress to pigs during transportation. There were no significant difference in skin damage scores of carcasses among stocking density groups. However, samples of 0.4㎡ stocking density group showed significantly (p$lt;0.01) higher pH₂ and pH_u levels compared to 0.5㎡ stocking density group. There were no significant differences in meat color (CIE L and a) among stocking density groups.
