Egg yolk is an essential ingredient for the preparation of a large variety of food emulsions. Thereby the emulsifying properties of egg yolk depend mainly on the physiological status of the two egg yolk fractions, granules (HDL) and plasma (LDL), which can be influenced by environmental conditions. Recent studies substantiate that a separate use of each fraction in innovative food products will...

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...

An extender has been developed with low-density lipoproteins (LDLs) that eliminates the microbial risks associated with the use of whole egg yolk. The objective of this study was to assess the effects of substituting egg yolk with LDLs for use as an extender in sperm preservation at 4 °C, as well as on spermatozoa motility, plasma membrane and acrosome integrity, at two different concentrations...

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...

Background: Low density lipoprotein (LDL) of egg yolk has been successfully used for stallion and bull semen cryopreservation. However, there is limited information to clarify the effect of LDL or lyophilized LDL on ram semen quality. On the other hand, during semen collection, dilution and cryopreservation we need to protect the spermatozoa from lipid peroxidation. Clove bud has polyphenolic c...

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...

It is widely believed that female birds strategically allocate androgens to yolk in the manner that best equips offspring for feeding conditions during their development. Because most avian studies have focused on multi-egg clutch species, and interpreted results within the framework of sibling competition, we still know little about how yolk androgens might be allocated in direct response to e...

Low-Density Lipoprotein (LDL) extracted from egg yolk has recently known can eliminate the adverse effect associated in use of fresh yolk. The role LDL liquid preservation at 4°C ram sperm not been explored. This research evaluates effects substituting with 4 °C on 5 days. objective this was to assess for as an extender 4°C, well spermatozoa motility, viability, morphology, plasma membrane, and...

Ovomacroglobulin and LDL fraction of egg yolk were effective to maintain the growth of established human cancer cell lines (Kato III, QG-90, Raji). A serum-free medium (BEM-841) containing 10 mM HEPES, 50 micrograms/ml of ovomacroglobulin, 0.1% (V/V) of LDL fraction of egg yolk, 10(-8) M catalase, 5 micrograms/ml of insulin, 5 micrograms/ml of transferrin, 5 ng/ml of selenium, 1 mg/ml of BSA, a...
