two breeds of chickens were used to develop reference family and detect qtls affecting egg quality traits: cocks of a native polish breed green-legged partidgenous (glp) and hens of rhode island red (rir). during the first 100 days of the laying period, the glp hens lay about 40 eggs weighting on average 50 g, whilst the rir flock laid 83 eggs with a mean weight of 60 g. qtl analysis of egg qua...

The difference between progeny from selected and unselected parents (T) was experimentally partitioned into net genetic change (G(A)), temporary favorable epistatic combinations (G(EP)) and egg-transmitted maternal environment (M) in two strains of Leghorns selected over 14 years for early pure-strain egg production. Differences among progeny from selected sires and dams, selected sires only, s...

BACKGROUND Accurate diagnosis of egg allergy by IgE testing is challenged by a large number of atopic subjects sensitized, but clinically tolerant to eggs. In addition, discrimination between allergy to raw only, or raw and cooked egg allergy is important. In this study, we investigate the diagnostic performance of IgE tests to native and denatured egg proteins. METHODS According to food chal...

Egg allergy is a wide spread condition which affects mainly children. Of all the other food allergies, egg allergy is the second most common one and has a high prevalence in developed countries. Egg allergy is caused by antigens found within the egg white and the egg yolk. Four egg white allergens have been identified and extensively studied over the past two decades, and the two identified egg...

The goal of this experiment was to investigating of effects of different levels of nano chromium (N-Cr) in diet on egg quality and blood chromium content of japanese quail. Two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. Experimental treatments include: 1) control national research council (NRC,...

The use of egg protein preparations in clinical trials to reduce the incidence of egg allergy among infants includes a number of preparations of egg. These include whole egg, egg white protein, and egg yolk preparations. The study of the differential immune responses to these allergenic proteins in comparison is suggested as a future research area of investigation.

Egg is the food that most often causes allergy in young Spanish children, with an incidence of 2.4-2.6% in the first 2 years of life. The prevalence of sensitisation and allergy to egg is greater in children with allergy to cow's milk and in those suffering atopic dermatitis. The protein component from egg white is the cause of the allergic response in child. The major allergens in egg white ar...
