This study investigated whether hydroxy-selenomethionine (OH-SeMet) improves broiler oxidative stress response to a greater extent than sodium selenite (SS) or seleno-yeast (SY) under environmental stress. Day-old male Cobb 500 broilers (12 cages/diet, 9 broilers/cage) were fed a selenium (Se)-deficient diet (0.047 mg Se/kg) supplemented with SS, SY or OHSeMet at 0.3 mg Se/kg for 42 days. Animals ...

The induction of oxidative stress by heat exposure, as well as the relationship between selenium (Se), selenoproteins and oxidative stress, is well described in the scientific literature (Habibian et al.,2015). Zhao et al. (2017) showed that hydroxy-selenomethionine (OH-SeMet) differently affected the expression of the selenogenome as compared to sodium selenite (SS). Hence, it was hypothesised th ...

A variety of oxidative reactions occur continuously within our cells in a dynamic environment. One common type of reaction – reduction-oxidation or redox reaction – plays a vital role in maintaining cellular functions. During these reactions, one couple loses electrons (becomes oxidised) and another gains the same electrons (becomes reduced). As a result, our cells have to maintain a d ...
