a total number of  5520 female and  480 male breeders (arbor acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. there were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

Egg size is a critical life-history trait because it can profoundly influence offspring fitness and the number of offspring that can be produced. Recently, interest has grown in how egg size influences fertilization rate and in turn how sperm availability might influence the evolution of egg size among broadcast-spawning marine invertebrates. In this article I review the empirical evidence on t...

Hen's egg white protein is a major cause of food allergy, and a considerable number of countries have introduced labeling directions for processed food products. To control compliance with these regulations, analytical assays for the detection of egg in manufactured foods have been developed. In this study, we have tested the performance of 3 commercially available kits for quantitative egg ana...

lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, gly...

Cichlid fishes are a textbook example of rapid speciation and exuberant diversity--this applies especially to haplochromines, a lineage with approximately 1800 species. Haplochromine males uniquely possess oval, bright spots on their anal fin, called 'egg-spots' or 'egg-dummies'. These are presumed to be an evolutionary key innovation that contributed to the tribe's evolutionary success. Egg-sp...

It has been suggested that follicle-stimulating hormone (FSH) may play a role in egg size/number trade-offs in oviparous vertebrates. We tested this hypothesis in an avian species by administering porcine FSH (pFSH) to intact, captive female zebra finches (Taeniopygia guttata) during egg formation. We predicted that (1) pFSH would increase the number of ovarian follicles recruited into rapid yo...

Chicken egg yolk antibodies (IgY) against camel immunoglobulins were generated and their specificity was shown by double immunodiffusion, immunoelectrophoresis, and Western blotting. Anti camel antibodies specifically react to camel antibodies in immunodiffusion and immunoelectrophoresis were demonstrated. Western blotting revealed that IgY antibodies recognize the heavy chain in a number of ma...
