  1. SEM standard error of mean.
  2. 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]
  3. 2Sows’ weight was registered 24 h after completion of farrowing
  4. 3In the statistical model, weights were analysed with number of piglets of the sow as covariant
  5. a,bMean values within a row with unlike superscript letters are significantly different
