The experiment was performed on 48 crossbred pigs (Polish Landrace x Pietrain), divided into three feeding groups: group I - fed a cereal-soybean diet containing 15 percent of total protein (1), group II - fed a diet containing 10 percent of wheat straw (2), group III - fed a diet containing 15 percent of wheat straw (3). The crude fiber content of the diets was as follows: (1) - 3.52 percent, (2) - 7.30 percent, (3) - 8.62 percent. The pigs were kept in litter pens (two animals per pen), fed at libitum and fattened from 70 to 110 kg of live weight. Dietary supplementation with wheat straw at the second stage of fattening negatively affected daily gains and feed conversion ratio. Differentiated feeding had a significant effect on the fatty acid profile in m. longissimus dorsi samples. The addition of wheat straw to diets had no impact on the blood biochemical indices analysed in the study
