BACKGROUND A few reports demonstrate the occurrence of egg allergy in adolescent and adult patients suffering from atopic dermatitis and the association of this allergy to other food and aeroallergens. AIMS AND OBJECTIVES The aim of this study is to evaluate the occurrence of egg allergy in patients suffering from atopic dermatitis at the age 14 years and older and to evaluate the relationshi...

When one heats the yolk, changes occur in the fragile elements that serve to support the vital life force within the egg. The egg yolk, in many ways, is not very different from your own cells. Once your temperature goes above 105 degrees you will start to suffer serious health problems. Similarly, heating the yolk above 105 degrees will also start to cause structural changes in many of the high...

In this experiment, a total of 128 Hy-line W36 hens at 63 weeks of age were used. The hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of Spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. All birds were housed in commercial cages, had ad libitum access ...

This study was conducted to evaluate the effect of different levels of sunflower meal (SFM) and niacin on laying hens performances, biochemical parameters, antioxidant status, and egg yolk cholesterol concentration. A total of 960, White Leghorn (Hy-Line W-36) commercial layers were randomly assigned to 12 groupsof 8 replicates with 10 hens each. Hens were allocated to diets 1 through 12 in a 3...

This study aims to determine the effect of using Hermetia illucens maggot in feed on internal and external quality broiler eggs.The used 80 laying hens aged 6 months which were divided into 4 treatments, 5 replications each replication consisted tails. The variables observed eggs (egg weight, egg shape index, shell thickness, weight) white yolk Haugh units, color). data obtained analyzed with a...

When Bacillus anthracis is grown in egg yolk medium, a reaction occurs which is presumably due to lecithinase (Colmer, 1948; McGaughey and Chu, 1948; Chu, 1949). In liquid egg yolk medium the lecithinase reaction is characterized by the formation of an opalescent suspension and flocculation of particles which rise to the top of the medium as a curd. A test such as this is usually referred to as...

Cryopreservation of semen from the Caspian brown trout (Salmo trutta caspius) and effects of extender type, freezing and thawing rates on fertilization ability were studied. After assessment of semen quality, one part of semen was diluted with three parts of different extender and decanted into 0.5ml straws. Freezing was carried out at two freezing levels, 1.5cm and 2cm above surface of liquid ...

A total of 2123 eggs obtained from Brown Leghorn hens (unselected since 1965, ISA Brown, commercial brown egg layer) and Babcock hens (commercial white egg layer) at 32, 50, and 68 wk of age were used to investigate relationships among measures of albumen quality and a functional property of albumen. The eggs were sampled fresh and after storage for 5 and 10 d. At sampling, eggs were weighed an...
