“…Cholesterol and cholesteryl esters in serum were both lower when vitamin E was in the oleic plus ascorbic acid diet. These results agree with previous work done in this laboratory which showed that vitamin E significantly reduced serum cholesterol in cockerels fed a 5% Wesson oil plus 1% cholesterol diet (Klopfenstein and Clegg, 1977). More vitamin E-related changes were associated with the 10% oleic acid diet than with the palmitic acid diet.…”

“…Recent studies have shown that dietary components interact and that all nutrientscarbohydrates, proteins, fiber, vitamins, and minerals, as well as lipids -can affect serum and tissue cholesterol, cholesteryl ester, and triglyceride compositions (Kritchevsky, 1978). Previous work in our laboratory has demonstrated the influence of ascorbic acid and vitamin E on serum lipid composition in cockerels fed Wesson oil and cholesterol (Klopfenstein and Clegg, 1977) and in cockerels administered diethylstilbestrol (Clegg et al, 1976).…”

Serum, aorta, heart, and liver tissues of cockerels reflected numerous changes in cholesterol and triglyceride composition when 5 or 10% oleic or palmitic acid, ascorbic acid, and vitamin E were added to their diets. Heart cholesterol concentration and liver cholesteryl ester content increased with the 10% oleic acid diet. Heart and liver cholesterol increased when ascorbic acid was added to 5% fatty acid diets, and heart cholesterol increased when ascorbic acid was added to the 10% palmitic acid diet. Vitamin E exerted a cholesterol- or cholesteryl ester-lowering effect on both 10% palmitic and 10% oleic acid diets. Heart and liver triglycerides were lower with the 5% oleic acid diet than with the 5% palmitic acid diet. The opposite effect was observed with the 10% fatty acid diet. Dietary ascorbic acid appeared to have some triglyceride-lowering effect. Dietary fatty acid composition was reflected in cockerel aorta, heart, liver, and serum fatty acid distribution, with oleic acid having the greater influence.

The work indicates the link bctween the serum cholesterol, atherosclerosis and certain metal metabolism. 122 adult albino rats were used in this study and classified into 5 groups: Control group, 29 rats fed the stock diet; group I, 32 rats fed the stock diet with 1 X cholesterol for 6 weeks; group 11, 36 rats fed the stock diet with 1 96 cholesterol for 8 week, group IIIA, 17 rats fed the stock diet and 0.2 ml oil/day orally for 8 weeks and group 11113, 18 rats fed the stock diet and 0.2 ml oil with cholesterol daily (50 mg cholesterol/l ml oil) for 8 weeks. The results obtained showed that: 1. A positive correlation was found between serum total cholesterol and serum coppcr, cadmium and Cd/Zn ratio, whereas a negative correlation occurred between serum total cholesterol and serum Zinc and Zn/Cu ratio. 2. A positive correlation was found between serum total cholesterol and cadmium, Zn/Cu and Cd/Zn ratio in liver. On the other hand, a negative correlation occurred between serum total cholestcrol and copper in liver. 3. A positive correlation was found between serum total cholesterol and Zn/Cu ratio in heart which was negative in heart copper, cadmium and Cd/Zn ratio. Histopathological examination of liver sections of animals treated with cholesterol revealed the presence of mild degree of fatty change, while the kidney tissues showed glomerular lesion in the form of obliteration of Bowman's capsule with increased cellularity inside, beside degenerated tubules and interstitial fibrosis.

An experiment was made to investigate the effect of diet composition on the utilization of beef tallow by adult cockerels. The birds were starved for 24 hr and then force-fed 1 of 3 basal diets (30 g) supplemented with 0, 1.5, 3.0, or 4.5 g of beef tallow. Excreta voided in the subsequent 24 hr was collected. True metabolizable energy (TME) and lipid availability values were measured. The TME value of tallow differed between basal diets and with the level of tallow input. A corn basal permitted greater TME values than a wheat basal but a supplement of soybean lecithins made the wheat basal as effective as the corn basal. Linoleic acid and phospholipid concentrations in the diet appeared to influence tallow utilization. The basic procedures of the TME bioassay permitted measurement of total lipid and fatty acid availability data. Lipid availability paralleled the TME data. Total lipid utilization ranged from 78 to 93% while the utilization of individual fatty acids varied both between acids and within acids between dietary treatments. Unsaturated fatty acids were well utilized (85 to 96%) while saturated acids were less well utilized (57 to 90%), particularly at high levels of input.
