AB  - The present study, researchers evaluated for the first time serum and salivary 
  8-Hydroxy-2'-deoxyguanosine (8-OHdG) and salivary Total Antioxidant Capacity 
  (TAC) during different stages of lactation and also during the dry period in 
  dairy cows. Cows at dairy farms that belong to Morioka City (Iwate, Japan) were 
  classified into five groups according to the month of lactation starting from 
  postpartum till the dry period. Oxidative DNA damage marker (8-OHdG) and TAC 
  were measured in saliva and serum samples using commercial ELISA kits. The results 
  revealed that salivary 8-OHdG levels were higher (p<0.01) than its corresponding 
  serum levels during both lactation and dry period. Serum levels of TAC were 
  significantly higher (p<0.01) than their salivary levels during lactation 
  and dry period. It could be concluded that oxidative DNA damage was prominent 
  during the dry period. Cows at the dry period have the highest serum level of 
  8-OHdG and the lowest salivary level of TAC when compared to lactating cows.
