ABSTRACT
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.
