PROTEINS, LIPOPROTEINS AND LIPIDS OF GOAT BLOOD-SERUM

The concentrations of proteins, lipoproteins and lipids in the sera of goats (Saanen, Alpen and crossbred) under physiological conditions, were investigated in this paper. The results obtained demonstrate that the concentrations of total proteins and relative contributions of the protein fractions separated by paper electrophoresis do not differ between Saanen, Alpen and crossbred goats. Goats have concentrations of total lipoproteins, beta lipoproteins and serum cholestelor significantly lower than man, but they are within the normal limits for lipid and lipoprotein in domestic animals. Only the phospholipid values were comparable with those in man. In agarose gel the serum lipoproteins of goats were separated into four fractions corresponding to human beta, pre-beta and two fractions with alpha mobility: alpha and pre-alpha lipoproteins. The major part of lipoproteins in goats was found as alpha lipoproteins (65-70%). The greater part of the phospholipids (about 70%) in the serum and about 45% of the cholesterol were carried in the high density liproprotein fraction.
