Internal and external qualities of eggs deteriorate with time. This process deterioration cannot be stopped but the rate at which it occurs can reduced. The aim this study is to evaluate main effect temperature storage duration on egg quality characteristics sensory evaluation fertile non-fertile eggs. A total 600 were obtained from Lohmann Brown hen, 44 weeks age. Roosters removed hen that lai...

Following the intra-allantoic injection of influenza A virus in embryonated eggs, a latent period of 4 to 6 hours has been observed, during which little or no active virus can be recovered from any of the embryonic fluids or tissues (1, 2). Microbial toxins probably exert their effect by altering cellular metabolism. Pappenheimer and Hendee have suggested that the diphtheria toxin, for example,...

The present study was carried out in co-operation between the Poultry Production Unit, Nuclear Research Center, Atomic Energy Authority, Cairo, Egypt and Ostrich Farm belonging to Faculty of Agriculture, Al-Azhar University. In an effort to improve the hatchability and hatching performance of ostrich eggs via testing the effect of in ovo injection of several nutrients and vitamins, as no simila...

the aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of ross 308 broiler chicks. fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...

The effects of broiler breeder hen age and dietary n-3 oils on yolk n-3 and n-6 fatty acid composition, egg quality, fertility, and hatchability were investigated. A total of 2,200 eggs were collected from wk 26 through 62 from Cobb breeder hens fed diets containing 1.75% fish oil + 1.75% yellow grease (low n-3) or 3.5% fish oil (high n-3). Eggs obtained from a commercial source were used as th...
