  1. WBC total white blood cells, NLR – neutrophils to lymphocytes ratio, MCV the mean cell volume-the ratio of the haematocrit to the concentration of red blood cells, MCH the mean corpuscular haemoglobin-the ratio of the total mass of haemoglobin to the number of red blood cells, MCHC the mean corpuscular haemoglobin concentration - identifies the amount of haemoglobin in a single red blood cell
  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. 2Effect of day is significant for all ages
  4. a,b,c,d,e,f,gMean values within a row with unlike superscript letters are significantly different
