Relationship between oxidative stress and the success of artificial insemination in dairy cows in a pasture-based system

The use of digital infrared thermography and measurement of oxidative stress biomarkers as tools to diagnose foot lesions in sheep

“…Albumin is a free radical scavenger but it is also the predominant oxidised protein contributing to AOPP formation (Celi, 2011b). Indeed, concentrations of AOPP can be associated with embryonic losses and are considered an indicator of inflammation and oxidative stress in dairy cows (Celi et al, 2011(Celi et al, , 2012. The lack of differences in albumin and AOPP concentrations between HG and FL affected rams may reflect the mild level of lesions observed in this study.…”

Plasma oxidative stress biomarkers and progesterone profiles in a dairy cow diagnosed with an ovarian follicular cyst

“…It is plausible that OS plays a crucial role in the cause and progression of a number of reproductive events and can influence the reproductive axis at different levels. For example, previous studies have shown that OS is associated with embryonic loss (Celi et al 2012;Celi et al 2011) and that OS has a role in the pathogenesis of follicular cystic ovarian disease (Rizzo et al 2009). Therefore, the objective of this study was to examine the plasma concentration of progesterone and OS biomarkers that were measured in cow 1285 diagnosed with an ovarian follicular cyst.…”

Clinical Use of Progesterone and Its Relation to Oxidative Stress in Ruminants

“…High ROS levels may also cause adverse pregnancy outcomes or embryonic/fetal losses [120][121][122] and are implicated in the etiopathogenesis of cystic ovarian disease [123]. ROS and the oxidative stress index in cows may be higher in the luteal phase than follicular phase, especially when progesterone is high.…”
