Eggs have a high nutritional value and are an important ingredient in many food products. Worldwide foodborne illnesses, such as salmonellosis linked to the consumption of eggs and raw egg products, are a major public health concern. This review focuses on previous studies that have investigated the procedures for the production of microbiologically safe eggs. Studies exploring pasteurization a...

Keeping Japanese quail is an economic way for producing egg, because of their early sexual maturity (laying egg after 35 days), high egg production (250–270 eggs per year), resistance to most of poultry disease and great egg production persistency on a high level (approximately 14–18 months) (MURAKAMI and ARIKI, 1998). Japanese quail maturation happens in about 6 weeks of age and mature females...

The nutrient composition of postparasitic females (newly emerged juveniles, newly molted adults, and spent adults) and eggs of Romanomermis culicivorax was studied. Throughout post-parasitic development, proteins increased and lipids decreased progressively as a proportion of the dry weight; the proportion of glycogen within the nematodes remained stable. The greatest decrease in the lipid moie...

Reciprocal and homologous mating experiments between Malaysian Aedes aegypti and Aedes albopictus mosquitoes were conducted in the laboratory. Two methods were employed, namely an artificial mating technique and a natural cage mating technique. The study demonstrated there exists a strong reproductive isolation between Ae. aegypti and Ae. albopictus. Insemination occurred in cross-mating experi...

In myrmecophilous Lepidoptera, mostly lycaenids and riodinids, caterpillars trick ants into transporting them to the ant nest where they feed on the brood or, in the more derived "cuckoo strategy", trigger regurgitations (trophallaxis) from the ants and obtain trophic eggs. We show for the first time that the caterpillars of a moth (Eublemma albifascia; Noctuidae; Acontiinae) also use this stra...

The aim of this study was to investigate the impact of production system (organic, conventional) on the quality of chicken eggs. Energetic value, carbohydrate, cholesterol, protein, fatty acid, sodium, potassium, phosphorus, dry matter and vitamin contents were evaluated. The mean content of cholesterol was 30%, and potassium 7%, greater in the organic eggs compared with the conventional eggs. ...

Eggs play an important role in the human diet and nutrition as an affordable nutrient-rich food commodity that contains highly digestible proteins, lipids, minerals, and vitamins (Fisinin et al., 2008). Over the past 35 years, global egg production has grown 203.2%, due to a rapidly increasing demand for proteins in the developing world (Windhorst, 2007). In 1970, the US was the greatest egg pr...

the aim of this study was to investigate the effects seaweeds gracilariopsis persica in diets on performance and tsh, t3 and t4 hormones in serum of laying quail. a total of 112 laying quails were randomly allocated into four dietary treatments (diets containing 0, 1, 3 and 5% seaweed) with 4 replicates of 7 birds each. the birds were fed on experimental diets for 12 weeks. eggs were collected ...

Production performance, including egg quality, and proportion of eggs laid in nests were studied in furnished experimental cages incorporating nests, litter baths, and perches. The study comprised a total of 972 hens of two genotypes: Lohmann Selected Leghorn (LSL) and Hy-Line White. The birds were studied from 20 to 80 wk of age, and conventional four-hen cages were included as a reference. In...

BACKGROUND INFORMATION At fertilization in mammalian eggs, the sperm induces a series of Ca(2+) oscillations via the production of inositol 1,4,5-trisphosphate. Increased inositol 1,4,5-trisphosphate production appears to be triggered by a sperm-derived PLCzeta (phospholipase C-zeta) that enters the egg after gamete fusion. The specific phosphatidylinositol 4,5-bisphosphate hydrolytic activity ...
