Most research on mechanisms of aging is being conducted in a very limited number of
classical model species, ie, laboratory mouse (Mus musculus), rat (Rattus norvegicus …

The egg-laying rate is an important indicator of egg production of laying ducks. Egg
production directly impacts the economic benefits of the duck industry. In order to obtain …

Abstract Background Japanese quail (Coturnix japonica), a recently domesticated poultry
species, is important not only as an agricultural product, but also as a model bird species for …

The preoptic area (POA) is one of the most evolutionarily conserved regions of the
vertebrate brain and contains subsets of neuropeptide-expressing neurons. Here we found …

Chemical risk assessment for avian species typically depends on information from toxicity
tests performed in adult birds. Early‐life stage (ELS) toxicity tests have been proposed as an …

RT-qPCR is the gold standard for candidate gene expression analysis. However, the
interpretation of RT-qPCR results depends on the proper use of internal controls, ie …

Early-life stage (ELS) avian toxicity tests have been proposed as a more ethical alternative
to traditional standardized tests with adult birds. At the same time,'omics approaches are …

Introduction Japanese quail are of significant economic value, providing protein nutrition to
humans through their reproductive activity; however, sexual dimorphism in this species …

Carcass yield of meat-type quails is strongly correlated with the weight of the birds at
slaughter (slaughter weight [SW]; body weight at 45 D of age). Moreover, prediction of …

Sexually dimorphic behaviors are often regulated by androgens and estrogens. Steroid
receptors and metabolism are control points for evolutionary changes in sexual dimorphism …
