The objective of this study was to comparatively analyse the physical parameters, basic chemical composition and the macro- and microelement content of offal obtained from fattening pigs raised in deep litter and slatted floor housing systems. The experiment involved a group of 80 Puławska fatteners, including 40 pigs kept in deep-litter pens (group I) and 40 pigs in slatted pens without bedding (group II). Offal (tongues, kidneys, hearts, lungs and livers) was evaluated for weight, physical characteristics (pH45, pH24, WHC), chemical composition (water, protein, fat) and the content of minerals: macro- (K, Na, Mg, Ca) and microelements (Zn, Fe, Mn, Cu). Based on the results obtained, associations were found between housing system and basic chemical composition of some offal, i.e. percentage of water (slatted floor&lt;deep litter) and protein (slatted floor>deep litter) in lungs, content of protein (slatted floor>deep litter) and fat (slatted floor&lt;deep litter) in liver, and content of fat in heart (slatted floor&lt;deep litter). The amount of macro- and microelements was significantly differentiated by the housing system with regard to the kidneys: potassium, magnesium, calcium and manganese (slatted floor&lt;deep litter), sodium (slatted floor>deep litter); lungs: sodium (slatted floor>deep litter), potassium (slatted floor&lt;deep litter); and liver: iron (slatted floor>deep litter) and copper (slatted floor&lt;deep litter). In general, the housing system of fattening pigs modified the physical parameters and chemical composition of the analysed offal.

Based on the results obtained, associations were found between housing system and basic chemical composition of some offal, i.e. percentage of water (slatted floor<deep litter) and protein (slatted floor>deep litter) in lungs, content of protein (slatted floor>deep litter) and fat (slatted floor<deep litter) in liver, and content of fat in heart (slatted floor<deep litter). The amount of macro- and microelements was significantly differentiated by the housing system with regard to the kidneys: potassium, magnesium, calcium and manganese (slatted floor<deep litter), sodium (slatted floor>deep litter); lungs: sodium (slatted floor>deep litter), potassium (slatted floor<deep litter); and liver: iron (slatted floor>deep litter) and copper (slatted floor<deep litter). In general, the housing system of fattening pigs modified the physical parameters and chemical composition of the analysed offal.
