Abstract

|
|
Eighty pigs (40 pigs per farm aged 40 days old) that had been raised on two commercial pig farms A and B were used to evaluate oxidative stress status. The results from each farm were compared to investigate a relationship between pig performance and oxidative stress status. Pig performance on farm A was relatively better than that on farm B for the period of 3 years. The level of plasma total antioxidant status (TAS) of the pigs in group 1 (farm A) was significantly higher (p=0.045<0.05 ) than that of the pigs in group 2 (farm B). The level of plasma total oxidant status (TOS) and oxidative stress index (OSI) value of the pigs in group 2 were significantly higher (p= 0.045<0.05 and p=0.001<0.05) than those of the pigs in group 1 These results revealed that pig performance was associated inversely with oxidative stress status.
