Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

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 ...
