Extract

Human dietary science gives preference to animal products low in fat and rich in polyunsaturated fatty acids (PUFA), especially n-3 (Goodnight, 1993). Dietary n-3 PUFA decreased the level of cholesterol and its low-density lipoprotein fractions in blood serum (Ulbricht, 1992). The problem of how to decrease the cholesterol content of meat by way of nutrition is still unresolved. Full-fat flax seeds and linseed oil are particularly rich in n-3 PUFA. Our studies failed to show a clear effect of linseed on cholesterol content of fattening pig tissues (Barowicz et al., 1997). The aim of the studies was to determine the effect of Ca salts of fatty acids made partly from linseed oil (Erafet M), linseed oil and full-fat flax in diets for finishing fatteners on total cholesterol content in the longissimus dorsi muscle. Moreover, the influence of fatteners sex was also taken under consideration.
