Food Science &Nutrition, Volume 13, Issue 9, September 2025.High energy levels in the diet increased weight gain and improved feed conversion ratio. Increasing the stocking density to 16 birds/m2 did not negatively impact broilers performance. ABSTRACT This study aimed to evaluate the effects of dietary metabolisable energy (ME) levels and stocking density (SD) on growth performance, carcass traits, blood ...

ACTH Stimulation Induced Self-Mutilation Behavior in the Golden Conure (Guaruba guarouba)
Animals, 2020 Psittacidae are very susceptible to chronic stress and behavioral disorders. Information regarding the endocrinology of the golden conure is scarce, especially about adrenocortical activity.

Social huddling and physiological thermoregulation are related to melanism in the nocturnal barn owl. [PDF]
, 2015 Endothermic animals vary in their physiological ability to maintain a constant body temperature. Since melanin-based coloration is related to thermoregulation and energy homeostasis, we predict that dark and pale melanic individuals adopt different ...

Neurogenomic landscape associated with status‐dependent cooperative behaviour
Molecular Ecology, Volume 34, Issue 15, August 2025.Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

Canadian Journal of Animal ScienceFault bars are visible deformities in the feather structure potentially related to the stress response and may be an interesting trait that can reflect robustness. This study’s objective was to describe fault bars along the length of domestic turkey feathers and investigate whether fault bars are associated with feather corticosterone (FCORT).

Manipulating Individual State During Migration: Carry‐Over Effects of Cumulative Stress on Survival
Ecology and Evolution, Volume 15, Issue 7, July 2025.Our field experiment examines the physiological consequences (stress hormone and body condition) of a prolonged stress on survival. A single prolonged stress event that occurs during a pivotal period (pre‐migration fattening period) can have lasting effects over several months impacting adult survival, a key demographic trait.

Feather corticosterone evaluated by ELISA in broilers: A potential tool to evaluate broiler welfare
Poultry Science, 2014 The measure of corticosterone (CORT) in feathers has been recently recognized as a valid and easily obtainable measure of chronic glucocorticoids secretion in avian species. This measure provides meaningful interpretations of how individuals respond to environmental perturbations. The growing interest of the public toward animal-food production welfare
