ABSTRACT
Retained placenta causes prolonged days of open periods which decrease reproductive efficiency. The study aimed to detect several blood biochemical parameters such as total protein (TP), Blood Urea Nitrogen (BUN), glucose, and calcium (Ca) in the retained placenta (RP). A total of 46 dairy cows were used in this study consisting of 21 cows with RP and 25 cows with non retained placentas (NRP). Blood samples were collected ± 3 weeks prepartum, ±1 week prepartum, 12 hours postpartum, and 3 weeks postpartum via the coccygeal or external jugular vein for biochemical parameter measurement. The results showed that total protein ± 3 weeks prepartum in RP and NRP were not significantly different (7.76 Vs 7.78 g/dl) then at ± 1 week prepartum was a decrease in RP (7.72 g/dl) while In the NRP was increase (9.00g/dl) significantly. In the other side, BUN concentrations at ±3 weeks prepartum in RP and NRP were not significantly different (12.79 vs 13.20 mg/dl), however at ±1 week prepartum, there was increase significant higher in RP compared to NRP ( 16.60 vs 14.41mg/dl). Glucose levels both prepartum and postpartum showed no significant difference. Meanwhile, calcium levels ± 3 weeks and ± 1 week prepartum both in RP and NRP were not significantly different until 3 weeks post partus and still in the normal level. Our results indicated that one week prepartus, BUN level was a significant increase in in RP compared to NRP. Therefore, BUN can be a strong indicator for predicting RP in dairy cows.
