Groups of 20 growing Large White castrated males were fed from 30 to 60 kg liveweight on diets containing different kinds of added fat: animal fat (group II), rape seed oil (III) and fat with 15 (group IV) or 20% (group V) unsaturated fatty acids (EUFA) content, and control group (I) without supplememnt. During the fattening period from 60 to 100 kg liveweight all the pigs were fed on the same mixture without fat supplementation. The use of fat additives containing high levels of EUFA (groups III, IV and V) increased the linolic acid content in back fat of fatteners slaughtered at 100 kg liveweight.
