Effect of iron glycine chelate supplementation on egg quality and egg iron enrichment in laying hens
Poultry Science, 2019 This study was conducted to evaluate the effects of iron glycine chelate (Fe-Gly) on egg quality of laying hens. A total of 810 laying hens (HyLine Variety White, 26 wk old) were randomly assigned to 6 groups, and each group consisting of 135 hens (5 ...

FEBS Open Bio, EarlyView.This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

Type of grinding of the main cereal of the diet affects production of brown egg-laying hens [PDF]
, 2014 The influence of method of grinding of the cereal of the diet on production and egg quality was studied in 420 Hy-line brown egg-laying hens. The design was completely randomized with six treatments arranged as a 3 × 2 factorial with three cereals ...

FEBS Open Bio, EarlyView.CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

Effects of cryogenic cooling of shell eggs on egg quality
Poultry Science, 2002 This study was conducted to investigate the effects of cryogenic cooling on shell egg quality. Gaseous nitrogen (GN), liquid nitrogen (LN), and gaseous carbon dioxide (GC) were utilized to rapidly cool eggs in a commercial egg processing facility and were compared to traditional cooling (TC).

Challenges in organic egg-production related to the nutritional quality of foraging material and introduction of 100% organic feeding [PDF]
, 2009 Organc hens have daily access to foraging material and the quality are important for egg-production due to varying contents of amino acids (aa) and dietary fibres (Hammershøj and Steenfeldt, 2005; Steenfeldt et al., 2007).
