AB  - This study aims to evaluate the oxidative stress during hot summer season using 
      serum oxidative stress biomarkers and elucidate the effects of serum antioxidant 
      vitamin levels in dairy and beef cows in a daytime grazing system. Blood samples 
      were collected once a month from eight Holstein Friesian (HF) and 10 Japanese 
      Black (JB) cows from November 2013 to October 2014. Serum values of derivatives 
      of reactive oxygen metabolites (d-ROMs) tended to be higher in March in both 
      breeds and those in HF cows were kept at higher (P<0.001) levels than those in JB 
      cows during the study period. Serum levels of biological antioxidant potential 
      (BAP) in both breeds were maintained at almost the same values during study 
      period. The OSI [(d-ROMs/BAP) x 100] values in both breeds showed similar 
      seasonal changes, i. e. increase from December to March and decrease from March 
      to August or September. In addition, the OSI values in HF cows were kept at 
      higher (P<0.01) levels than those in JB cows during the study period. Serum 
      concentrations of alpha-tocopherol, beta-carotene, blood urea nitrogen and total 
      cholesterol showed similar seasonal changes in both breeds, low in the winter and 
      high from spring to summer, which may be attributed to the pasture grass intake. 
      Opposite changes in OSI values and serum concentrations of alpha-tocopherol and 
      beta-carotene indicated that antioxidant vitamin levels could affect oxidative 
      stress status.
