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 15 percent of oat bran (2), group III - fed a diet containing 30 percent of oat bran (3). The crude fiber content of the diets was as follows: (1) - 3.30 percent, (2) - 6.22 percent, (3) - 9.69 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 oat bran negatively affected daily gains and feed conversion ratio. Carcass meatiness was high in all experimental groups and was not differed statistically in groups. Crude fiber levels in diets had a significant effect on the concentrations of polyunsatureted fatty acids in m. longissimus dorsi samples. The addition of oat bran to diets resulted in an increase in the blood levels of HDL cholesterol and a decrease in the blood levels of LDL cholesterol
