Egg yolk oil is a natural source of bioactive compounds such as unsaturated fatty acids, oil soluble vitamins, pigments and others. Bioactive compound content in egg yolk oil depends from its content in eggs, from which oil was extracted. Many studies show that bioactive compound content in egg is correlated to the content of these compounds in hen feed, but there is also an opinion that hen ho...

BACKGROUND In any calf rearing system it is desirable to obtain healthy animals, and reduce morbidity, mortality, and economic losses. Bovine syndesmochorial placentation prevents the direct transfer of bovine immunoglobulins to the fetus, and calves are born hypogammaglobulinemic. These calves therefore require colostrum immediately after birth. Colostrum is rich in immunoglobulins (Ig) and it...

Excess consumption of egg especially its yolk has been implicated in hyperlipidaemia (high level of cholesterol and triglyceride in the blood). Conversely, soluble dietary fibers, probably due to their ability to bind free lipid molecules, appear to play an important role in protecting against hyperlipidaemia. This study sought to evaluate the comparative effects of selected sources of fibers: ...

This study was conducted to investigate the effect of fenugreek and copper sulfate supplementation levels and their combinations in diets on productive, physiological performance, lipids profile in blood, liver or yolk, fertility and hatchability of Japanese quail for a period of 7 weeks (from 8 to 14 weeks). A total number of 162 mature Japanese quail birds were used in this study. Quail birds...

The avian egg is an excellent source of nutrients consisting of components with beneficial properties but there is limited knowledge on the effect of cooking methods and gastrointestinal digestion on the antioxidant activity of eggs. The present study was focused on the effect of cooking and simulated gastrointestinal digestion on antioxidant activity of eggs using ORAC, ABTS and DPPH assays. T...

MIESCHER [1870] observed that after prolonged peptic digestion of egg-yolk an insoluble substance separated out. This substance was foundby Bunge [1885] to contain iron in organic combination and was named by him " haematogen" because of its close resemblance to haemoglobin, at least so far as empirical composition was concerned. The chemical nature of this substance was investigated in more de...

Mercury contamination of wildlife populations has been documented widely in recent years as biomonitoring has become an important tool for assessing environmental contamination. Avian eggs provide an ideal assay material for Hg biomonitoring, particularly when the collection of eggs is simplified by using cavity-nesting species that nest in easily monitored nest boxes. However, studies are need...
