Effect of Uniformity of Eggshell Thickness on Eggshell Quality in Chickens
The Journal of Poultry Science, 2014 Numerous parameters have been proposed to evaluate eggshell quality in order to reduce losses from damaged eggshells. The uniformity of eggshell thickness (UET), as a newly proposed parameter, is defined as the reciprocal of the coefficient of variation

Excess Dietary Chloride Depresses Eggshell Quality
Poultry Science, 1984 Abstract An experiment was conducted to determine the influence of dietary monovalent electrolytes on egg production by Single Comb White Leghorn hens. Diets containing nutritionally adequate or excessive levels of sodium, potassium, or chloride were provided to hens during the first year of egg production from 206 to 233, 331 to 360, and 465 to 490 ...

Polymorphisms in eggshell organic matrix genes are associated with eggshell quality measurements in pedigree Rhode Island Red hens [PDF]
Animal Genetics, 2008 SummaryNovel and traditional eggshell quality measurements were made from up to 2000 commercial pedigree hens for a candidate gene association analysis with organic eggshell matrix genes: ovocleidin‐116, osteopontin (SPP1), ovocalyxin‐32 (RARRES1), ovotransferrin (LTF), ovalbumin and ovocalyxin‐36, as well as key genes in the maintenance and function ...
