ABSTRACT
2
This study aims to evaluate the oxidative stress during hot summer season using
3
serum oxidative stress biomarkers and elucidate the effects of serum antioxidant
4
vitamin levels in dairy and beef cows in a daytime grazing system. Blood samples
5
were collected once a month from eight Holstein Friesian (HF) and 10 Japanese Black
6
(JB) cows from November 2013 to October 2014. Serum values of derivatives of
7
reactive oxygen metabolites (d-ROMs) tended to be higher in March in both breeds
8
and those in HF cows were kept at higher (P
