Dietary supplementation of 0.95% valine in protein‐restricted diets optimizes reproductive performance, egg quality, and ovarian follicular development in laying Japanese quail. Higher levels do not provide additional benefits and may increase hepatic metabolic demand, highlighting the importance of precise amino acid formulation in low‐protein feeding

ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

Spatial Orientation in Japanese Quails (Coturnix coturnix japonica)
Finding a given location can be based on a variety of strategies, for example on the estimation of spatial relations between landmarks, called spatial orientation. In galliform birds, spatial orientation has been demonstrated convincingly in very young domestic chicks. We wanted to know whether adult Japanese quails (Coturnix coturnix japonica) without

Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lasalocid A sodium (Avatec® 150G) as a coccidiostat for turkeys, pheasants, guinea fowl, quails and partridges. The additive currently on the market complies with the existing conditions of authorisation.

We experimentally manipulated the presence of supplemental food at a bird feeder and monitored subcutaneous temperature (Tsub) in 15 overwintering black‐capped chickadees (Poecile atricapillus) during feeder visits to investigate whether food availability shapes daytime Tsub.
