  1. The effects of dietary forage, social hierarchy, and stocking density on stress in lactating cows during relocation

    Pence, Kristen JeanVirginia Tech2005

    … effects of treatment on MY, lameness, behaviors, plasma cortisol, cow cleanliness, and DMI were monitored. In experiment one, cows fed grass or alfalfa hay diets had higher plasma cortisol concentrations on the day of relocation than cows fed TMR, but there were no differences in DMI or MY. Cows …

  2. Cortisol responsive gene networks in cardiovascular disease

    Bankier, Sean AlexanderThe University of Edinburgh2022

    Increased plasma cortisol levels are associated with Cardiovascular Disease (CVD) and CVD risk factors, however the tissue specific mechanisms underpinning this process are poorly understood. A genome wide meta-analysis by the CORtisol NETwork (CORNET) consortium identified genetic variants, …
