Response of three laying hen genotypes to two feed calcium levels
Czech Journal of Animal Science, 2019 The present study aimed to evaluate the effect of two dietary Ca levels (3.00% vs 3.50%) in three hen genotypes (ISA Brown, Bovans Brown and Moravia BSL) on their laying performance and quality of their eggs.

Errors in Measuring and Calculating Eggshell Quality
Poultry Science, 1994 Abstract Three experiments were conducted to examine potential errors in measuring or calculating eggshell quality. In Experiment 1, specific gravity of eggs was measured in increments of .001 and .0025, and the increments of .0025 were combined for increments of .005.

Eggshell Conductance and Other Functional Qualities of Ostrich Eggs
Poultry Science, 1996 Eggshell conductance was measured and eggshell conductance constants were calculated for eggs from ostriches. In addition, egg water, yolk, albumen, shell, and total solids were measured in an effort to determine the maternal investment of ostrich eggs.

Polymorphisms in eggshell organic matrix genes are associated with eggshell quality measurements in pedigree Rhode Island Red hens [PDF]
Animal Genetics, 2009 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 ...

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 ...
