Subcutaneous or oral administration of the polyunsaturated fatty acid linoleic acid prolongs survival of skin allografts in mice. Mice fed on a diet deficient in polyunsaturated fatty acids show a relative immunopotentiation, as indicated by accelerated skin allograft rejection and decreased incidence and rate of development of methylcholanthrene-induced tumors. These observations support the h...

The fatty acid composition of liver mitochondrial phospholipids from rats rendered deficient in essential unsaturated fatty acids has been determined, and compared with that of rats fed a diet containing corn oil. In addition to marked reductions in the amounts of linoleic and arachidonic acids esterified a t the &position of ethanolamine-, inositol-, and choline glycerophosphatides, the defici...

The present study aims to evaluate the effects of feeding palm oil by-products based diets on different muscle fatty acid profiles in goats. Thirty-two Cacang × Boer goats were randomly assigned to four dietary treatments: (1) control diet (CD), (2) 80% decanter cake diet (DCD), (3) 80% palm kernel cake diet (PKCD) and (4) CD plus 5% palm oil (PO) supplemented diet (CPOD). After 100 days of fee...

We examined the effect of the positional distribution of fatty acids within dietary triglycerides on serum lipoproteins. Sixty subjects consumed two diets of equal fatty acid composition for 3 wk each. In the palm oil diet 82% of palmitic acid was attached to the outer two carbon atoms of glycerol, and 18% to the middle carbon. In the diet rich in enzymatically modified palm oil these figures w...

The aim of the study was to evaluated the content of selected fatty acids in muscle tissue of pigs fed with feed mixtures with different sources of fat. Forty crossbred gilts were divided into four groups and fed with control diet (C) or diet containing sunflower (S), linseed (L) or CLA. The highest content (P<0.001) of linoleic acid was found in CLA and S group, the highest amount of alpha-lin...

In order to study the response of a poorly differentiated tumor to nutritional manipulation, the Yoshida ascites hepatoma (AH 130) was grown in rats fed an essential fatty acid (EFA)-deficient diet and in rats fed a control diet. Hepatomas, livers, and blood plasma from host rats and normal rats were studied as to the effects of EFA deficiency on the lipid composition. Normal rats fed an EFA-de...

The influence of pyridoxine upon the metabolic conversion of linoleic acid to arachidonic acid was studied in the livers of rats maintained w ith different kinds and conditions of dietary fats. In the basal diet group, the liver phospholipid fraction of the pyridoxine deficient animals revealed significantly higher percentage of linoleic acid and significantly lower percentage of arachidohic ac...

OBJECTIVE: We investigated whether the intake of virgin olive oil or sunflower oil and performance of physical exercise (at different states) affect plasma levels of triacylglycerols, total cholesterol, and fatty acid profile in rats. METHODS: The study was carried out with six groups of male rats subjected for 8 wk to a diet based on virgin olive oil (three groups) or sunflower oil (three grou...

I. Changing cows from a diet with low hay and high flaked maize content, which depressed milk fat secretion, to a high-roughage diet resulted in increased milk fat secretion and in changes in the pattern of rumen fermentation and in the composition of the blood plasma. 2. During the 1st week following the change in diet the proportions of propionic and valeric acids in the rumen decreased and t...

The objectives of this study were to determine the effects of conjugated linoleic acid (CLA) or betaine on the growth performance, carcass characteristics and fatty acid composition in backfat and belly fat of pigs fed distillers dried grains with solubles (DDGS). Thirty-two (60±2 kg) crossbred barrows (Duroc×Landrace×Yorkshine) were assigned to one of four diets randomly: (1) the control diet ...
