The effect of HD on antioxidant enzyme activities in the plasma of sows throughout the lactation period. (a) Relationship between superoxide dismutase (SOD) activity and day of lactation in the plasma of sows fed a control (Δ symbol) or a hemp seed diet (□ symbol); (b) Relationship between catalase (CAT) activity and day of lactation in the plasma of sows fed a control (Δ symbol) or a hemp seed diet (□ symbol); (c) Relationship between glutathione peroxidase (GPx) activity and day of lactation in the plasma of sows fed a control (Δ symbol) or a hemp seed diet (□ symbol). The p-values for the effects of treatment (diet), time and diet-time interaction are shown. Data are means ± SEM (n = 5). Asterisk (*) indicates significance (p < 0.05 *).
