This study was aimed at determining the effect of irradiation of shell eggs on the physiochemical and functional properties of liquid egg white during storage. Color and textural parameters of irradiated liquid egg white after cooking were also determined. Shell eggs were irradiated at 0, 2.5, 5, or 10 kGy using a linear accelerator. Egg white was separated from yolk and stored in at 4°C up to ...

The objective of this work was to determine the influence natural (marigold flower extract) and synthetic (canthaxanthin) pigments on shelf life eggs from light laying hens in final stages production. 288 birds were distributed a completely randomized design, with eight treatments, consisted four levels marigold extract (2.1; 2.4; 2.7 3 ppm) canthaxanthin (0.4 ; 0.7; 1,0 1.3 ppm), each treatmen...

a 70-days experiment was conducted to investigate the effects of natural zeolite (clinoptelolite) on the performance of commercial laying hens. 288 hy-line w36 strain laying hens (50 weeks old) were allotted to 6 dietary treatments including basal diet as control and basal diet supplemented with 1, 2, 3, 4 and 5% zeolite that were fed ad -libitum throughout the experiment. experimental diets fo...

The objectives of our study were to propose a new definition for persistency of egg production and to develop a mathematical model to describe the egg production curve, one that includes a new measure for persistency, based on the proposed definition, for use as a selection criterion to improve total egg production. Persistency of egg production is an important determining factor for total egg ...

A fitness function is needed for a Genetic Algorithm (GA) to work, and it appears natural that the combination of objectives and constraints into a single scalar function using arithmetic operations is appropriate. One problem with this approach, however, is that accurate scalar information must be provided on the range of objectives and constraints, to avoid one of them from dominating the oth...

Conventional gastrointestinal motility tests cause pain; therefore, newer noninvasive methods are desired. Noninvasive methods facilitate the measurement of motility close to the normal physiological state, provide new valid findings, and may contribute to the development of associated fields. Electrogastrography (EGG) measures the electrical activity of the stomach through electrodes placed ov...

We examined whether the previously reported low cost of embryonic development in pelicans could be attributed to a more efficient conversion of egg energy to hatchling tissues as a result of high initial egg water content, low embryonic metabolic rate and growth later in incubation than in more precocious species. We therefore determined egg and hatchling composition and the development of embr...

A study was conducted to determine the effect of feeding high concentrations of corn distillers dried grains with solubles (DDGS) on egg production and the internal quality of eggs from laying hens. Four diets were formulated to contain 0, 17, 35, or 50% corn DDGS. A total of two hundred forty 54-wk-old Single-Comb White Leghorn laying hens were randomly allotted to 2 birds per cage with 3 cons...
