The effect of a diet fortified with polyunsaturated
fatty acids on the level of selected elements in the
myocardium of growing pigs

The experiment was carried out on 3 groups of fatteners (Large White x Polish Landrace), 7 per group, housed in individual cages for 102 days from a body weight of 25 to 102 kg. They were fed complete feed containing 4% of the following types of fats: lard, linseed oil, fish by-product oil. After slaughter, samples of the myocardium were collected from the pigs and the content of elements was determined spectrometrically. It was found that linseed oil added to the mixture significantly (P < 0.05) increased Fe and Cr contents, whereas fish by-product oil increased (P < 0.05) the Mg and Cr level in dry matter of heart tissue in pigs.
