This study was conducted to evaluate the relationship between calving body condition score (BCS) as well as first and second milk test postpartum with clinical and subclinical mastitis prevalence. After calving 117 multiparous cows were divided to two groups based on their BCS as fat and normal conditioned and milk samples were taken in week one and two postpartum. The results showed BCS at calving time had no significant relationships with udder health. Milk protein and fat had significant associations with udder health in week 1 and 2 postpartum; however in none of weeks no meaningful relationships were found between milk fat to protein ratio with udder inflammation. Therefore, calving BCS and fat to protein ratio are not reliable markers for clinical or subclinical mastitis incidence; however milk fat and protein in week 1 and 2 postpartum can be used as proper markers for predicting subclinical mastitis in dairy cows at early lactation.
