Abstract This study aimed to investigate the effects of dietary supplementation with modified-hen-egg-yolk on plasma lipids and lipoprotein profiles in rats. During four-week-experiment, 64 Wistar rats were divided into four groups 16 (eight both sexes), fed commercial rat food (group C); containing 70% mixture 30% freshly cooked egg yolk originating from laying hen eggs 3% fish oil F); palm ol...

since many years it has been a general belief in iranian traditional medicine that unripe grape juice (verjuice) has lipid-lowering effect. this study was designed to test this hypothesis. fifty rabbits were selected and divided into 5 groups with 10 rabbits in each. group 1 had no supplemental diet. group 2 were fed 10 ml egg yolk daily and group 3 were fed 10 ml egg yolk plus 20 ml verjuice d...

This experiment was conducted to investigate the effects of different levels of L-carnitine on productive performance, egg quality and blood parameters in laying hens. Forty-eight Hy-Line W-36 egg Layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage). Four dietary treatments were prepared by supplementing L-carnitine (0, 50, 100 and 150 mg/kg of diet)...

BACKGROUND Lutein and zeaxanthin may reduce the risk of dry, age-related macular degeneration because of their photo-oxidative role as macular pigment. OBJECTIVE The present study evaluated serum lutein, zeaxanthin, and macular pigment optical density (MPOD) responses at 0.25 degrees , 0.5 degrees , and 1 degree retinal eccentricities to the consumption of 2 and 4 egg yolks/d by older adults ...

BACKGROUND Because of egg cholesterol content, reduction in egg consumption is generally recommended to reduce risk of cardiovascular disease. Recently, however, evidence has been accumulating to suggest that dietary cholesterol is less relevant to cardiovascular risk than dietary saturated fat. This randomized controlled crossover trial was conducted to determine the effects of egg ingestion o...

The purpose of this study was to examine the effect of biopolymer encapsulation on the digestion of total lipids and cholesterol in egg yolk using an in vitro human digestion model. Egg yolks were encapsulated with 1% cellulose, pectin, or chitosan. The samples were then passed through an in vitro human digestion model that simulated the composition of mouth saliva, stomach acid, and the intest...

this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...

this experiment was conducted to investigate the effects of various levels of cichorium intybus andcopper on performance and egg yolk cholesterol. total of 324 layer hens (hy-line w-36) were used in arandomized complete blocks with nine treatments, three replications of 12 birds in each from 38 to 50weeks of age. experimental diets include control, four levels of copper (150, 200, 250 and 300 m...

To study the pathogenesis of cholesterol gallstones, we fed 24 adult male prairie dogs a high cholesterol, egg yolk diet. 13 control animals received a cholesterol-free diet. All animals fed the egg yolk diet formed multiple gallstones in 2-6 months' time. These stones contained cholesterol, 77+/-14% by dry weight. No stones ocurred in the control group. The egg yolk-fed animals developed bile ...
