OverviewAI-generated summary
Brittni P Littlejohn's research focuses on the physiological and molecular responses of animals to environmental stressors. Her work investigates the influence of factors such as diet, endophyte-infected forages, and maternal stress on animal health and development. A significant portion of her research utilizes DNA methylation patterns as a biomarker for stress and programming effects. She has studied these epigenetic changes in various tissues and leukocytes in Brahman cattle, exploring their potential as surrogates for stress-axis tissues. Additionally, her projects examine the impact of melatonin supplementation on uterine hemodynamics and offspring growth in beef cows grazing endophyte-infected tall fescue. Her work also extends to investigating the effects of gossypol from cottonseed meal on pig growth performance and blood parameters. Littlejohn has published 64 papers and has an h-index of 6 with 134 citations.
