Inheritance of hatchability in broiler chickens and its relationship to egg quality traits
44
TL;DR: In this article, the authors investigate the genetic basis of variability in hatchability over age using a longitudinal model and investigate the relationship between hatchability and internal and external egg quality traits measured at 48 wk of age.

Breed and feed affect amino acid contents of egg yolk and eggshell color in chickens.
TL;DR: It is suggested that it is possible to produce designer eggs with enriched components, including yolk amino acids, by adjusting both genetic and environmental factors, which represents a first step in understanding the mechanisms underlying the production of value-added eggs in chickens.

Metabolomics Approach Reveals the Effects of Breed and Feed on the Composition of Chicken Eggs.
TL;DR: This study shows that yolk and albumen metabolites will be affected by breed and feed, which is the first step towards manipulating genetic and environmental factors to create “designer eggs.”

Cuticle deposition improves the biosecurity of eggs through the laying cycle and can be measured on hatching eggs without compromising embryonic development
Maureen M. Bain,Jiangxia Zheng,Melissa Zigler,Natasha Whenham,Fiona Quinlan-Pluck,Anita C. Jones,Mark Roberts,Wiebke Icken,Victor E Olori,Ian C. Dunn +9 more
TL;DR: It is concluded that cuticle deposition is important in preventing bacterial penetration of eggs in genetically divergent breeds of chicken and that the measurement can be practically incorporated into breeding programs.

TL;DR: Hatch of fertile eggs has sufficient genetic variation in these White Leghorn lines to expect improvement by within-line selection, especially if supported by a reduction in total egg weight and selection for higher egg production, yolk percentage and shell breaking strength.

TL;DR: Negative genetic and phenotypic correlations were found between body weight at 12 week of age with egg number, egg mass, fertility, hatchability, egg shape index, yolk%, shell% and shell thickens, while the positive effect were found for body weight for sexual maturity, age at sexual maturity and the period until the first 10 eggs.

A new look at the statistical model identification
TL;DR: In this article, a new estimate minimum information theoretical criterion estimate (MAICE) is introduced for the purpose of statistical identification, which is free from the ambiguities inherent in the application of conventional hypothesis testing procedure.

Maximum Likelihood Approaches to Variance Component Estimation and to Related Problems
TL;DR: In this paper, the authors proposed a restricted maximum likelihood (reml) approach which takes into account the loss in degrees of freedom resulting from estimating fixed effects, and developed a satisfactory asymptotic theory for estimators of variance components.

Egg physical characteristics and hatchability
TL;DR: For those eggs, whose parameters do not fall in to the average range, the incubation process is more successful if the shell is thicker than average, the eggs are more pointed rather than round, and the contents firm, which results in the more successful hatching of embryos from heavier eggs.

Science and the Art of Incubation
TL;DR: The use of egg-cooling during incubation as a means of manipulating takeoff times, the use of water-vapor conductance monitoring by weight to predict the optimal humidity conditions for batches of eggs from different strains and species, cuticle-stripping to improve embryonic respiratory gas exchange, and some aspects of egg hygiene are dealt with.
