Towards to Changes in Blood Indices as Early Diagnosis of Retained Placenta

This study aims to examine hematological parameters for early diagnosis of retained placenta (RP) during three stages of postpartum periods in dairy cattle. For this purpose, thirty post calving dairy cows with RP (group I) and healthy (group II) were selected (n=15 each). The cows were placed into 3 stages of period, from 1 to 3 weeks after parturition. Then, blood samples were collected from two groups. No significant differences were observed in hematological indices between two groups of cattle. The results showed that RP does not cause to significant changes in some hematological parameters as well as total protein and albumin (Alb) when compared to the healthy cows (p<0.05). Also, significant increases in the concentration of fibrinogen (Fb) was observed in diseased cows during 1 to 2 weeks when compared to the healthy (p<0.05). Our results indicated, in spite of hematological parameter, some serum indices including Fib could be successfully applied as indicators for RP in post calving dairy cattle. Therefore, blood indices cannot be used for early diagnosis of RP in dairy cattle.
