(a) Relationship between SOD activity and day of lactation in the plasma of piglets fed a control (Δ symbol) or a hemp seed diet (□ symbol); (b) Relationship between CAT activity and day of lactation in the plasma of piglets fed a control (Δ symbol) or a hemp seed diet (□ symbol); (c) Relationship between GPx activity and day of lactation in the plasma of piglets 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 = 8). Asterisk (*) indicates significance (p < 0.05 *).
