COMPARATIVE-STUDIES OF THE SERUM-LIPOPROTEINS AND LIPIDS IN DOMESTIC SWINE AND WILD BOAR

The differences between the concentrations of serum lipoproteins and l ipids of domestic swine and wild boar under physiological conditions, were investigated in this paper. The results obtained demonstrate that the major part of the lipoproteins in domestic swine and wild boars c onsisted of beta lipoproteins (43-54%) and alpha lipoproteins (about 3 0%), as in man. The concentrations of total serum lipoproteins and bet a lipoproteins did not differ between domestic swine and wild boar. Ho wever, wild boars had concentrations of serum cholesterol and serum ph ospholipids significantly lower (p<0,001) than domestic swine. The dis tribution of cholesterol and phospholipids between the various lipopro tein fractions of the sera of domestic swine and wild boars was simila r to that found in humans. Most of the serum cholesterol (64,0% in swi ne and 70,0% wild boars) was in beta lipoproteins and most of the seru m phospholipids (60,0% in swine and 71,0% in wild boars) were found in the high density lipoprotein fraction.
