Graded Levels of Dietary Valine in Protein‐Restricted Diets: Effects on Reproductive Performance and Tissue Morphology in Laying Japanese Quail

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
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

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 710-718, August 2026.
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)

open access: yesPLoS ONE, 2011
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

Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
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 ...

Assessment of the feed additive consisting of lasalocid A sodium (Avatec® 150G) for turkeys, pheasants, guinea fowl, quails and partridges except laying birds thereof for the renewal of its authorisation (Zoetis Belgium SA)

open access: yesEFSA Journal, Volume 24, Issue 8, August 2026.
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.

Evidence of Small Changes in Daytime Body Temperature in Active Black‐Capped Chickadees in Response to Supplemental Food Availability

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
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.

Desempenho de codornas de corte submetidas a diferentes níveis de proteína bruta e energia metabolizável Performance of meat-type quails subjected the different levels of crude protein and metabolizable energy

open access: yesCiência Rural, 2013
Objetivou-se avaliar o desempenho de codornas de corte, submetidas a diferentes níveis de proteína bruta (PB) e energia metabolizável (EM). Avaliaram-se 720 codornas distribuídas em delineamento em blocos ao acaso, em esquema fatorial (5x3), com cinco ...
