    ADSA Foundation Scholar Award: Shakin' off the rust—Oxidative stress and redox status as underlying factors of immune dysfunction in periparturient cows and preweaning calves by Angel Abuelo

    Published 2025-08-01
    “…A key factor responsible for the development of immune dysfunction in transition cows and newborn calves is oxidative stress (OS), which results from the imbalance between the production of reactive oxygen and nitrogen species (ROS/RNS) during times of high metabolic demands and the availability of antioxidant defenses that are needed to reduce oxidant-induced cellular damage and subsequent loss of function. Elevated OS is linked to increased disease susceptibility, impaired immune responses, and inflammation. …”
