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]
²Day implies the sampling at respective days of the gestation period (108 and 112), and days of lactation period (2, 16, 28)
³Such fatty acids as C4:0, C8:0, C10:0, C12:0,C15:0, C17:1, C20:0,C22:0 were present (< 0.3%)
⁴Effect of day is significant for all sampling days, except C18:4n-3 P > 0.05
^a,bMean values within a row with unlike superscript letters are significantly different
