In this work the cholesterol content of chicken eggs produced by two lines (high and low weight) representing the 31st generation of selection for divergent growth was studied. Divergent selection for body weight at 8 weeks of age resulted in changes in egg size and consequently in the weight of egg components. Higher values (P≤0.001) were observed in eggs from the high weight (D+) line for egg...

A commercial egg-type chicken (ISA Brown; CEC) and a dual-purpose pure breed of the Korean Native Chicken (KNC) were compared for yolk to albumen (Y:A) ratio and their major egg characteristics at seven different ages. The eggs from KNC were significantly (P < 0.01) lighter in egg, albumen, and shell weight than those from CEC. However, the yolk weight and Y:A ratio of the eggs from KNC were si...

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 ...

Egg has valuable nutrients however; these may be affected by many factors. In this study, it was aimed to determine the effects of cage type, oviposition time and egg storage period on quality characteristics laying hens. A total 410 eggs were collected from unenriched enriched cages in morning afternoon. After weighed, they stored at 21oC 20% relative humidity until 30th day storage. It determ...

This experiment was conducted to determine in the threonine requirements laying japanese quail. A total of 240 female Japanese quails were used from 10 to 17 weeks of age, in a completely randomized design (CRD). Experimental treatments consisted of three treatments: basal diet (0.69% threonine), basal diet+0.05% L- threonine (0.74% threonine) and basal diet+0.1% L- threonine (0.79% threonine),...

The leopard gecko (Eublepharis macularius) exhibits temperature-dependent sex determination as well as temperature-influenced polymorphisms. Research suggests that in oviparous reptiles with temperature-dependent sex determination, steroid hormones in the yolk might influence sex determination and sexual differentiation. From captive leopard geckos that were all from the same incubation tempera...

The present study was carried out to determine some egg quality characteristics and storage related changes using computer assisted digital image analysis (CADIA) in an 18-month old moulted brown layer (Lohmann Brown) flock. A total of 150 newly laid eggs was randomly divided into two groups: eggs from the control group were broken immediately, while the remainder were stored at 18 C and 55% RH...

Cold and immobilization stressors can generate oxidative stress as well as skeletal muscle fatigue. Free radicals cause oxidative degradation of lipids, proteins, nucleic acids, and carbohydrates molecules, thereby compromising cell integrity and function. Quail egg had been described as being very functional biochemically, due to the essential biomolecules it contains in very regulated quantit...

Bacterial penetration shortly after inoculation has not been reported extensively. Four strains of bacteria, Salmonella typhimurium (ST), Escherichia coli (EC), Pseudomonas earuginosa (PE) and Stapylococcus aureus (SA), in chicken egg components of Bovan brown were analyzed by serial dilution and scanning electron microscopy. After exposing the fresh eggs to the bacterial strains at concentrati...
