SEM standard error of mean
¹H = basal diet and hemp seed oil in ratio 95:5, HS = basal diet and mix of soybean and hemp seed oils (50:50) in ratio 95:5; S = basal diet and soybean oil in ratio 95:5; basal diet formulated according to Danish Nutrient Standards for Lactating Sows [24]
²Effect of day is significant for all lactation stages, except total n-3 fatty acids P = 0.12
^a,b,cMean values within a row with unlike superscript letters are significantly different
