Surface coatings of eggs are used to extend the shelf life and minimize economic loss. Edible mineral oil is as a coating material but several problems associated with it plant waxes tested alternatives. “Boomi” (Litsea glutinosa) “dawul kurundu” (Neolitsea cassia) found throughout Sri Lanka barks these trees widely in indigenous medicine due their antibacterial properties. But, information on ...

Albumen was removed from broiler eggs before the start of incubation to induce prenatal protein under-nutrition in chicken embryos. With this method, the direct effect of protein deficiency was investigated, differing from mammalian models manipulating the maternal diet where indirect, hormonal effects can interfere. Based on the estimated albumen/egg weight ratio, 10 % of albumen was removed w...

The acoustic propagation properties of egg yolk and albumen are characterized in the frequency range 20-400 MHz by the bioultrasonic spectroscopy system using an ultrasonic transmission comparison method. Significant differences in the attenuation, velocity, impedance, and density among yolk and thick and outer thin albumen are observed. The acoustic properties of 10% aqueous solutions of ovalb...

The gonad of Helix aspersa contains a factor which can stimulate in a dose-dependent manner galactogen synthesis in albumen gland explants cultured in vitro. The stimulatory activity appears to be greater when the gonad is predominantly male than when it is predominantly female. The albumen gland of virgin snails does not respond in vitro to the gonadal influence. The receptivity of the albumen...

The external dimensions, weight and contents (yolk, albumen, shell) of Double Yolked (DY) and Single Yolked (SY) eggs of the duck (Anas platyrhynchos domesticus) were measured and compared. The yolks in DY eggs did not differ in weight (p = 0.144), although each double yolk was significantly lighter than the yolk of a SY egg (p<0.001). DY albumen weight was below that expected of a SY egg of co...

Industry observations indicate that a proportion of shell eggs exhibit an uncharacteristic spreading of the thin albumen when they are broken-out for fast-food preparation. Because the height and characteristics of the thick albumen are unaffected, the eggs are classified as Grade A. Preliminary observations discounted effects of egg storage or contaminated feed. Two experiments were conducted ...

This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...

The current research work was conducted to compare the external and internal egg quality parameters of different breeds peacock. For this purpose, 130 freshly laid eggs 2 species 11 (n = 10 per breed) were obtained from captive breeding facilities. In Pavo muticus muticus, higher weight (106.57 ± 0.69), length (7.21 0.01), width (5.31 breadth (28.18 volume (100.84 0.48) recorded. However, shape...

Recently, some nondestructive methods for the assessment of albumen freshness were developed. Among others, visible near-infrared transmission spectroscopy and low-resolution proton nuclear magnetic resonance (LR (1)H NMR) measurements were proposed. This study was performed to evaluate the potential of the combined measurement of visible near-infrared transmission spectroscopy and LR (1)H NMR ...
