The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding
Animal Research and One Health, EarlyView.A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

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 ...

Mass sperm motility is associated with fertility in sheep.
Animal Reproduction Science, 2015 The study was to focus on the relationship between wave motion (mass sperm motility, measured by a mass sperm motility score, manually assessed by artificial insemination (AI) center operators) and fertility in male sheep. A dataset of 711,562 artificial

Animal Research and One Health, EarlyView.Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...
