BACKGROUND Baked egg is tolerated by a majority of egg-allergic children. OBJECTIVE To characterize immunologic changes associated with ingestion of baked egg and evaluate the role that baked egg diets play in the development of tolerance to regular egg. METHODS Egg-allergic subjects who tolerated baked egg challenge incorporated baked egg into their diet. Immunologic parameters were measur...

kutum, rutilus frisii kutum, is an commercially important fish in the caspian sea. the fish enters the rivers leading to the caspian sea for spawning. one of these rivers is shiroud river. in the artificial propagation process of kutum, different factors are involved in quality and quantity of female broods eggs and also in the best temperature and migration time for spawning. the influence of ...

  This study involves the investigation of Tinca tinca (L., 1758) living in Kapulukaya Reservoir in Turkey. It was observed that the fish reach sexual maturity at the age of III and the breeding period starts in May and ends in July. The mean monthly gonadosomatic indices varied from 1.38 ±0.06 (in October) to 8.01±1.03 (in May). According to monthly variations of the GSI, spawning of the tench...

an experiment was conducted to evaluate the effect of dietary crude protein and lysine levels on quality and quantity of egg production. fifteen diets consisted of 3 levels of protein (14, 15 and 16%) and 5 levels of lysine (0.71, 0.74, 0.77, 0.80 and 0.83 %) in a 35 factorial arrangement were provided. each diet was randomly fed to 4 replicates of 12 birds, during four periods of 4 weeks (28-...

This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...

INTRODUCTION Egg allergy is an adverse immune-system reaction of an IgE-mediated type, which can happen in children after egg intake and several times after their first egg intake. OBJECTIVES Compare the results of the oral egg-challenge test in two groups of egg-sensitised children, with and without prior intake. PATIENTS AND METHODS Retrospective study of two egg-sensitised groups (72 sub...

this study was conducted to evaluate the effect of egg yolk and cooling on ram coated spermatozoa. semen was collected from three ram by artificial vagina contacted with a tube containing tris- fructose-egg yolk 15%. samples were pooled, centrifuged by 700 g for 10 min and removed supernatant. then, samples were diluted by tris-glucose and centrifuged again to remove seminal plasma and egg yolk...

Between 1997 and 1998 the breeding density, nest sites, clutch size and egg dimensions of the magpie (Pica pica) was investigated in a 7 km2 area in the Krapina river valley. We recorded a high breeding density of 4.79 pairs/km2 (during both years). The nests were situated at a height of 1–16 m above ground (mean = 6.74 m). Magpie nests were found in at least 9 species of bushes and trees. We r...

Sodium bentonite can bind to dietary pigment and decreases yolk color scale. Sodium bentonite is one of the main parts of Formycine® Gold, the effect of different levels of Formycine® Gold and dietary pigment on egg quality, egg yolk color and performance criteria of laying hens from 26 to 34 week of age were studied. One hundred ninety two Hy-Line hens were divided into 24 groups of 8 birds ea...
