The effect of a dietary supplementation of gallic acid and linoleic acid mixture (MGL) and their synthetic salt, sodium 2,3-dihydroxy-5-(((9E,12E)-octadeca-9,12-dienyloxy)carbonyl)phenolate (NGL), on egg quality was investigated. A total of 120 laying hens were allotted into five groups over 4weeks of the experimental period. Birds were fed the following diets: (1) control [commercial diet (CD)...

Screwworm flies, Cochliomyia hominivorax (Coquerel), were fed on honey and spray dried egg product; honey, molasses, and spray dried egg product; honey and spray dried meat protein; as well as on a control diet of honey and horsemeat, which is the standard diet used for screwworm adult colony in the mass-rearing facility. In general, the weight of eggs laid by females fed on the diet of spray d...

The present study was carried out to determine some egg quality characteristics and storage related changes using computer assisted digital image analysis (CADIA) in an 18-month old moulted brown layer (Lohmann Brown) flock. A total of 150 newly laid eggs was randomly divided into two groups: eggs from the control group were broken immediately, while the remainder were stored at 18 C and 55% RH...

Egg is an important source of animal protein with its nutritional substances. These substances and the quality characteristics egg are affected by physicochemical changes effect various factors during storage. Different studies have been carried out to preserve values eggs In these studies, Ultraviolet applications were mostly used for sanitation eggs, while made determine internal without brea...

Egg white is an important contributor to the protection of eggs against bacterial contaminations during the first half of incubation (day zero to 12), prior to the egg white transfer into the amniotic fluid to be orally absorbed by the embryo. This protective system relies on an arsenal of antimicrobial proteins and on intrinsic physicochemical properties that are generally unfavorable for bact...

Egg yolk undergoes an irreversible gelation process at temperatures below −6 °C, which greatly impairs its application and increases apparent viscosity. This work was aimed to investigate the effect of salt pH in preventing frozen-thawed egg yolk. Before freezing, 5% added into pasteurized liquid yolk, then adjusted different levels (5.7, 6.0 6.3) with citric acid. After that, stored −18 °C for...

In this study, the effect of basil seed gum (BSG) on the stability and rheological properties of egg white albumin (EWA) emulsions was investigated. A constant amount of EWA (0.5% w/v) and different concentrations of BSG (0-0.3% w/v) were used for the manufacture and stabilization of oil-in-water emulsions (30% w/w). The results showed that by increasing BSG concentration, the storage (21 days)...

The aim of this research was to evaluate the changes in the Gelato ice cream properties at different levels of sweet whey protein concentrate (WPC) substitutions of egg yolk. Samples were made with two levels of egg yolk (4.5 and 9%). For each level one control sample with no WPC addition and four levels of WPC substitutions (20, 50, 80 and 100%) were made. Three replications of each treatment ...

BACKGROUND The yolk of insect eggs is a cellular domain specialized in the storage of reserve components for embryo development. The reserve macromolecules are stored in different organelles and their interactions with the embryo cells are mostly unknown. Acidocalcisomes are lysosome-related organelles characterized by their acidic nature, high electron density and large content of polyphosphat...

This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...
