Stress ossidativo nella bovina da latte in correlazione alle modalità di allevamento

Abstract

The terms oxidative stress, oxidative damage, free radical and antioxidant have become an integrated part of the variety of scientific discussions. Oxidative stress biomarkers have been proposed as new and reliable indicators of animal welfare since stress of any origin can deplete the body’s antioxidant resources. Observations made in cattle kept in good or harsh conditions by the same research group have revealed that oxidative stress biomarkers were highest in cattle living in hard conditions. This observation highlights the need for a multidisciplinary approach to the diagnosis and resolution of OS-related diseases such as nutrition, metabolism, behavior (Marco-Ramell A et al., 2012) in order to ultimately satisfy the welfare of dairy cattle. The improving of the various breeding conditions optimizes the animal behaviour and reduces the incidence of oxidative stress.
