Used in research settings to measure levels of glutathione peroxidase enzyme activity in biological samples from bovine sources. Helps assess oxidative stress and antioxidant capacity in cattle, supporting studies in veterinary medicine, animal health, and livestock production. Commonly applied in monitoring disease states such as mastitis, metabolic disorders, and reproductive issues where oxidative damage plays a role. Enables researchers to evaluate the effectiveness of dietary supplements, antioxidants, and therapeutic interventions in improving bovine health and productivity.
