|
In a trial involving 124 pigs, the effect of spring, summer and winter transport on pig behaviour, skin damage of carcass, muscle pH and color were investigated. They were transported for on average 1hr 30 min from farm to 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 percentage of standing pigs during the journey were highest in spring, and lowest in summer. The percentage of lying pigs were examine highest in summer. The skin damage scores of carcasses was significantly (p$lt;0.05) higher in spring transport than those in summer and winter. The pH₂ and pHu values of pork were significantly (p$lt;0.05) higher in spring transport than those in summer and winter transport. In analysis of meat color, lightness (CIE L) values were significantly (p$lt;0.05) higher in summer transport than those in spring and winter transport. Redness (CIE a) and yellowness (b) was significantly (p$lt;0.05) lower in spring transport than those in summer and winter transport.
