Abstract
Summary
The serum lipoproteins of normal dogs were studied while on different dietary regimens including low fat and various high fat diets containing coconut, olive, safflower, or menhaden oil. The serum low density (beta lipoprotein) fraction was increased nearly threefold by feeding coconut oil in contrast to the other diets which, except for a small increase with olive oil, showed little effect on the lipoproteins. High density lipoproteins, while constituting the major fraction in dogs, did not respond to the diets. Reasonably good separation into alpha and beta lipoprotein by ultracentrifugation was demonstrated by electrophoresis of the fractions on polyacrylamide gels.
