<abstract xmlns="http://www.w3.org/1999/xhtml">Animal health and welfare can be assessed using biochemical and haematological markers of the blood. The values of these parameters depend in part on the quantity and quality of feed ingredients, i.e. feed protein and feed additives. The aim of the study was to determine the effect of including fermented rapeseed meal (FRSM) in dry feeding system on haematological and biochemical blood parameters of sows and piglets. The experimental material comprised 30 primiparous gilts and 30 multiparous sows after their second lactation. They were randomly divided into two groups of equal size – control and experimental. The animals in control groups CG (15 gilts) and CS (15 sows) received a standard diet for pregnant or lactating sows, depending on the reproductive period. Experimental groups EG and ES were 15 gilts and 15 multiparous sows, respectively, receiving feed with a 4% share of FRSM in place of soybean meal up to 100 d of gestation. In addition, from 100 d of gestation to 7 d of lactation, the sows in these groups received feed with a 9% share of FRSM, and then again a diet with a 4% share of FRSM until the end of lactation. Blood samples were taken from 6 animals from each group in two periods: at 100 days of pregnancy (late pregnancy) and at 27 days of lactation (late lactation). Blood from piglets was taken at 27 days of age (before weaning), from two piglets from each sow (one gilt and one barrow), taking into account the average body weight in the litter. Haematological parameters: Ht, Hb and RBC were determined in whole blood. The plasma content of minerals, activity of selected enzymes and biochemical parameters of sows, gilts and piglets were determined. The diet containing fermented rapeseed meal, fed to pregnant and lactating sows, increased the level of Ht and Hb and RBC content and mineral content (phosphorus, calcium and iron) in the plasma. This effect was mainly observed in primiparous sows. The inclusion of FRSM in the diet of sows reduced the plasma content of total cholesterol and triacylglycerols in sows and piglets, as well as liver enzyme activity, particularly AST in piglets. The use of fermented rapeseed meal in sow diet resulted in better use of mineral compounds, improvement of production effects and health parameters of sow and piglet blood.</abstract>
