Plasma concentrations of 25- hydroxy vitamin D 3 (A) and α-tocopherol (B) of pigs fed experimental diets. Samples were analysed before (basal) and after (final) feeding diets containing 23% casein or 23% lupin protein isolate for 4 weeks. Values are means (n = 12) with standard deviations. *Significantly different between the two groups (P < 0.05, Student’s t- test). #Significantly different between basal and final means within one group (P < 0.05, paired t-test).
