CAT and fetal growth restriction: Results showed that IUGR pigs had higher MDA (p < 0.01) and PC (p = 0.03) levels in leg muscles and had significantly lower GPX (p = 0.02), CAT (p < 0.01) and POD (p = 0.02) activities than NBW pigs but did not show significant difference in GSH and TSH contents (p > 0.05).
