In this study, 162 students in the 6 year Pharmacy Program at the School of Pharmacy, Iwate Medical University were asked to prepare liposomal preparations using chicken egg yolk and to evaluate their properties with the aim of developing novel liposomes. High-purity lecithins are generally used for preparing liposomes but they are expensive. On the other hand, egg yolk has various components, ...

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01)...

experiment was conducted to evaluate the effect of different levels of egg yolk for coating and storing spermatozoa. ejaculates were collected from four rams. in each session, second ejaculates (n=4) were collected in a tube containing 1 ml coating buffers which were prepared by 10, 15 or 20% egg yolk plus tris-fructose. samples were pooled, centrifuged and the supernatant removed in the labora...

a total of 2000 records of egg quality of 746 birds and body weight data from 17th generation of fars native fowl breeding station were used to estimate the genetic parameters of egg quality and body weight traits. six univariate animal models with different random effects were fitted for each trait. a model with direct additive genetic and maternal permanent environmental effects was the most ...

Protein by-products from the extraction of lecithin from egg yolk can be converted into value-added products, such as bioactive hydrolysates and peptides that have potential health enhancing antioxidant, and antihypertensive properties. In this study, the antioxidant and angiotensin converting enzyme (ACE) inhibitory activities of peptides isolated and purified from egg yolk protein were invest...

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. The...

Egg-tempera painting is a pictorial technique widely used in the Middle Ages, although poorly studied its physico-chemical aspects until now. Here we show how NMR relaxometry and rheology can be combined to probe egg-tempera paints shed new light on their structure behavior. Based recipes of 15th century, model formulations with egg yolk green earth have been reproduced characterize physicochem...

Immunoglobulin Y (IgY) is the predominant antibody found in hen's (Gallus domesticus) egg yolk. This antibody, developed against several microorganisms in hen egg yolk, has been successfully used as an alternative to immunoglobulins from mammals for use in immunodiagnostics and immunotherapy. Enteropathogenic Escherichia coli (E.coli) F4 is the main etiological agent associated with swine neona...

In the current scenario of increasing and emerging drug resistance in various microbial pathogens, traditional antibiotics are becoming less effective and thus globally research has focused on developing alternative therapeutic regimens having efficient germ killing abilities. The leading alternatives include use of phages, prebiotics, probiotics, cytokines, avian egg yolk antibodies, toll like...

Twenty-four, 79-wk-old White Leghorn hens were assigned randomly to three diets containing 0, 2.5, or 5.0% conjugated linoleic acid (CLA). The diets were fed for 4 wk to determine the effect of dietary CLA on quality characteristics of eggs. Eggs were collected daily and stored at 4 C for 1, 7, 21, or 49 d. At the designated times, the eggs were processed to evaluate water content, fatty acid c...
