Assessment of testicular corticosterone biosynthesis in adult male rats.

PLoS ONE, 2015
Corticosterone is synthesized in the adrenal glands and is circulated throughout the body to perform regulatory functions in various tissues. The testis is known to synthesize and secrete testosterone and other androgens.

Comparison of Corticosterone Concentrations in Dermal Secretions and Urine in Free-Ranging Marine Toads (Rhinella marina) in Human Care

Veterinary Medicine International, 2023
Corticosterone concentrations have been measured in amphibians by collecting blood or urine samples. However, blood sampling is invasive, and urine can be difficult to collect.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

Chronic treatment with glucocorticoids does not affect egg quality but increases cortisol deposition into egg albumen and elicits changes to the heterophil to lymphocyte ratio in a sex-dependent manner

Frontiers in Physiology, 2023
During chronic stress, there is an initial increase in glucocorticoid (GC) levels, but they then return to low, albeit not baseline, levels. Recent studies have renewed interest in cortisol in that it may also have important roles in the stress response.
