Journal ArticleDOI
Variations in the morphology, distribution, and arrangement of feathers in domesticated birds
TL;DR: Variations in the morphology, distribution and arrangement of feathers in domesticated birds require also a concern for animal welfare because certain alleles responsible for integumentary variations in domestication birds have pleiotropic effects, which often affect normal behaviour and viability.
Journal ArticleDOI
Current approaches to avoid the culling of day-old male chicks in the layer industry, with special reference to spectroscopic methods
M-E Krautwald-Junghanns,Kerstin Cramer,B Fischer,A. Förster,Roberta Galli,Friedrich Kremer,Emmanuel Urandu Mapesa,Sven Meissner,R. Preisinger,Grit Preusse,Christian Schnabel,Gerald Steiner,Thomas Bartels +12 more
TL;DR: One of the prerequisites of in ovo sex determination is a practicable method that can be used in industry, which needs to be rapid, cost‐efficient, and highly precise and negative impacts on hatching rate, animal health, and/or performance parameters should be limited.
Journal ArticleDOI
In ovo sexing of chicken eggs by fluorescence spectroscopy
Roberta Galli,Grit Preusse,Ortrud Uckermann,Thomas Bartels,Maria-Elisabeth Krautwald-Junghanns,Edmund Koch,Gerald Steiner,Gerald Steiner +7 more
TL;DR: The fluorescence of blood obtained in ovo by illumination of embryonic vessels with a IR laser displays spectral differences that can be employed for sexing of eggs in early stage of incubation, before onset of embryo sensitivity and without hindering its development into a healthy chick.
Journal ArticleDOI
Gender determination of fertilized unincubated chicken eggs by infrared spectroscopic imaging.
Gerald Steiner,Thomas Bartels,Allison L. Stelling,Maria-Elisabeth Krautwald-Junghanns,Herbert Fuhrmann,Valdas Sablinskas,Edmund Koch +6 more
TL;DR: FT-IR spectroscopic imaging allows the gender determination of unincubated eggs within a few seconds based on the accurate determination of the different DNA contents in blastoderm cells of both sexes.
Journal ArticleDOI
Sexing of chicken eggs by fluorescence and Raman spectroscopy through the shell membrane.
Roberta Galli,Grit Preusse,Christian Schnabel,Thomas Bartels,Kerstin Cramer,Maria Elisabeth Krautwald-Junghanns,Edmund Koch,Gerald Steiner,Gerald Steiner +8 more
TL;DR: It is shown that near infrared Raman and fluorescence spectroscopy can be performed on perfused extraembryonic vessels while leaving the inner egg shell membrane intact, and this approach offers the best premises towards practical deployment in the hatcheries.
