Two trials were conducted to study the effects of different dietary fats on the performance, carcass quality and meat quality of 75 crossbred growing pigs. The experimental diets contained 14.3% butter oil (BO), low erucic acid rapeseed oil (RO), sunflower oil (SO) or partially hydrogenated sunflower oil (HSO). The cream (CR) content of the diets was 29.4%. The dietary fat addition comprised about 36% of the net energy content of the diets. The fatty acid composition of the dietary fats had a clear influence on the fatty acid composition of the adipose tissue of the pigs. Vegetable oils (RO and SO) increased the unsaturated fatty acid content of the adipose tissue and decreased the firmness of the backfat compared to the effects by milk fat (80, CR) (p
