There was a significant difference in the shell strength of chicken eggs with different curvatures of the large end. Holding temperatures of eggs significantly influenced shell strength but not shell membrane strength. There was a significant negative correlation in chicken eggs between shell strength and membrane strength in small and medium curvature groups but not in the large curvature grou...

the experiment was designed to study the changes in production performance and egg quality of old laying hens after injection of different doses of growth hormone (gh) and testosterone (ts). a total of 160 old laying hens (hyline w-36) at 73 wks of age were randomly assigned to four treatments with four replicates and 10 birds in each replicate in a completely randomized design. treatment group...

zyme (LY) are the major allergens for patients with egg allergy.2・5-7) OA, OT, OM, and LY constitute 51, 12, 11, and 3.5weight%, respectively, of the total protein in egg white.S) Some groups reported that OM plays a more important role in the pathogenesis of allergic reactions to egg white than other egg white proteins.9・'O} OM is a highly soluble glycoprotein with a molecular weight of 28,OOO...

Many insect eggs are able to avoid mechanical injury and desiccation because they are protected by an egg-shell or chorion which is tough, rigid and relatively waterproof. These properties tend to make it impermeable to gases, and since the egg contains a living embryo, there must be provision for the diffusion of an adequate volume of oxygen into the egg. The way in which this is achieved has ...

This study was carried out to investigate the effect of two housing systems on external and internal egg characteristics of a commercial laying bird. Two hundred and eighty pullet of Nera layers were divided into two even group kept in different housing systems (deep litter vs cage). External and internal egg quality traits were examined at 26, 30, 34 and 38wk. Data were then collected on egg w...

In the present study, silica aerogel- egg shell was synthesized for dye removal of colored wastewater. The nano composite structure was characterized by Fourier transform infrared spectra FTIR and scanning electron microscope SEM.The ability of nano composite absorption was assessed for removal basic violet 16BV16 dye from aqueous solutions and was compared with two other adsorbents such as egg...

Shell eggs were irradiated and the physico-chemical, and functional properties of egg yolk and white were determined. The color of egg yolk was not affected, but the viscosity of egg white was dramatically lowered and became watery by irradiation. The foam capacity and foam stability of egg white were significantly decreased due to protein oxidation by irradiation. However, the texture characte...
