Abstract
|
|
|
In a trial involving 120 pigs, the effects of transport time on blood profile and meat quality in pigs were investigated. One group of 60 animals was subjected to 20min and the others to 2 h transport time, and held in lairage for 1 h 30min. There was not significantly different in the carcass weight, backfat thickness and carcass grade between groups. Cortisol and lactic dehydrogenase(LDH) concentrations were significantly(P＜0.05) higher in the group transported for 2 h compared with the group transported for 20min. There was not significantly different(P＞0.05) in meat quality(?_(１), ?_(ｕ), drip loss, cooking loss, hardness, CIE L^(＊), a^(＊), b^9＊) and NPPC) and skin damage of port carcass between groups.
These results imply that the stress could be affected by transport time in transit without meat quality.
