In recent years, the consumer’s desire for healthier foods has increased the demand for animal products containing low cholesterol and enriched with omega-3 fatty acids. In response to the perceived need, poultry researchers have focused on reducing egg yolk cholesterol to satisfy the health conscious of consumers. The present study was conducted to determine the effects of dietary forage legum...

an eight week study was conducted to investigate the effect of inclusion of tomato waste meal in layer diets on laying performance, egg quality and lipid profile as a means to reduce feed cost and pollution. four laying diets containing tomato waste meal (twm) at four levels of 0, 3, 6 or 9% were assigned randomly to 4 groups of 40 birds divided among four replicates of 10 birds in each dietary...

A 3 × 2 factorial arrangements with completely randomized design, with a total of 72 Leghorn Hy-line (W-36) laying hens in the second cycle (98 wk old) of production were randomly assigned to 24 wire cages (45.7×30×30 cm3) and fed with diets containing three levels of guar meal (GM; 0, 4 and 8%) and two levels of β-mannanase (Hemicell®) enzyme (0.00 and 0.05%) for 12 wk period. There...

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 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...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

The effect of a dietary supplementation of gallic acid and linoleic acid mixture (MGL) and their synthetic salt, sodium 2,3-dihydroxy-5-(((9E,12E)-octadeca-9,12-dienyloxy)carbonyl)phenolate (NGL), on egg quality was investigated. A total of 120 laying hens were allotted into five groups over 4weeks of the experimental period. Birds were fed the following diets: (1) control [commercial diet (CD)...

The aim was to evaluate the functional efficiency of a probiotic strain Enterococcus faecium M74 in the feed on egg yolk weight, egg yolk fat and cholesterol contents of Shaver Starcross 288 hens. Feed in the experimental group was enriched with a probiotic additive containing of 5*10 viable Enterococcus faecium per g. Egg samples a total 30 pcs per group were collected during the first egg-lay...

In this work the cholesterol content of chicken eggs produced by two lines (high and low weight) representing the 31st generation of selection for divergent growth was studied. Divergent selection for body weight at 8 weeks of age resulted in changes in egg size and consequently in the weight of egg components. Higher values (P≤0.001) were observed in eggs from the high weight (D+) line for egg...

Experiments were conducted to evaluate the potential for dietary garlic to influence egg yolk cholesterol concentrations and overall performance in different layer strains. Thirty-six, 28-wk-old, Hisex Brown,Isa Brown, Lohmann, Starcross, Babcock, and Starcross-579 strains (six hens per strain) were fed diets supplemented with 0 (control), 2, 4, 6, 8, or 10% sun-dried garlic paste for 6 wk.
