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...

Unlike mosquitoes, which produce yolk-loaded eggs only after a blood meal, Drosophila egg production is not invariantly coupled to nutrition. Before this study, precisely why the immature egg stages do not accumulate yolk by endocytosis was unknown. By following the expression patterns of the Drosophila transmembrane vitellogenin receptor, Yolkless, the authors found transcripts and receptor pr...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

An experiment was conducted to investigate the effects of using different levels of Red Pepper powder (RP) and Marigold flower powder (MF) on egg production, egg yolk color andsome blood metabolites in laying hens. Ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. The birds were fed a corn-soybean...

background and objectives: diagnosis of avian tuberculosis by conventional culture method is still considered as the “gold standard” technique. the main objective of this study was to compare growth of mycobacterium avium subsp. avium on four specific mycobacterial cultures such as glycerinated lowenstein-jensen medium, pyruvate-enriched lowenstein- jensen medium, mycobactin j-supplemented herr...

Serum (n = 1,636) and egg yolk (n = 802) samples collected from hens on four commercial egg farms in Florida were tested for the presence of specific antibodies to Mycoplasma gallisepticum in a commercially available enzyme-linked immunosorbent assay. No significant differences were noted between serum and egg yolk samples with respect to distribution of positive, suspect, and negative test res...

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 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...

When one heats the yolk, changes occur in the fragile elements that serve to support the vital life force within the egg. The egg yolk, in many ways, is not very different from your own cells. Once your temperature goes above 105 degrees you will start to suffer serious health problems. Similarly, heating the yolk above 105 degrees will also start to cause structural changes in many of the high...
