Elevating Testosterone and Androstenedione Produces Temporary Sex-Dependent Variation in Japanese Quail (Coturnix japonica) Embryonic Development. [PDF]

open access: yesJ Exp Zool A Ecol Integr Physiol
ABSTRACT Vertebrate growth rates may respond to maternally supplied steroids, yet injections of individual hormones into avian eggs of different species have produced inconsistent results. This might be because diverse steroids' concentrations are naturally correlated in yolks, injections are not elevating hormones at critical times in development, or ...

Influence of environmental temperature and electrolyte balance on the performance of quails (Coturnix Coturnix Coturnix) [PDF]

open access: yesRevista Brasileira de Ciência Avícola, 2014
High environmental temperatures have a negative effect on the production efficiency of poultry reared in hot climates. This study evaluated the efficiency of electrolyte supplementation under high environmental temperature conditions by manipulating water and feed electrolyte balance (EB) on the survival and performance of European quails.

Digital Three-Dimensional Atlas of Quail Development Using High-Resolution MRI [PDF]

open access: yes, 2007
We present an archetypal set of three-dimensional digital atlases of the quail embryo based on microscopic magnetic resonance imaging (µMRI). The atlases are composed of three modules: (1) images of fixed ex ovo quail, ranging in age from embryonic day 5
