Abstract
This study aimed firstly to early diagnosis of clinical cases of postpartum endometritis between 21 and 28 days in milk using different methods like external inspection of discharges on tail or prenium, palpation per rectum of uterus followed by ultrasonography, vaginal inspection and finally vaginal smear and secondly to study the effect of the endometritis treatment on postpartum reproductive parameters. In this study, animals were divided into 3 groups; Group1 (Control group): Healthy cows that did not receive any treatment. Group2 (Cephapirin group): Each case received 500 mg cephapirin intrauterine .Group3 (PGF2α group): Each case received 500 µg cloprostenol. The results of this study showed that conception rates were 100%, 95% and 85% in control group, cephapirin group and PGF2α group, respectively. Moreover, in the control group the first service conception rate was 85 %, while in the cephapirin group the first service conception rate was 10%. On the other hand, administration of PGF2α showed first service conception rate of 20 %. The services per conception were 1.3, 2.21, 1.76 in control group, cephapirin group and PGF2α group, respectively. In the control group, the average days open was 67.90± 2.8 while on using cephapirin the average days open was 82.00± 4.0 which is significantly higher than in PGF2α group (75.58 ± 2.2). The calving interval for control group was 337.90 ±2.8. On the other hand, the calving interval was significantly higher in cephapirin group (352.00 ± 4.0) than in PGF2α group (345.58± 2.2). From this study it could be concluded that administration of PGF2α as well as cephapirin are very effective for treatment of postpartum bovine endometritis with subsequent improvement of bovine reproductive performance
