Reproductive performance in buffaloes is greatly affected by postpartum anestrus condition. So, the purpose of the current study was to compare between the normal cyclic and postpartum anestrus Egyptian buffaloes (Bubalus bubalis) in their serum hormonal, metabolic and minerals profile. Blood samples were collected from 20 normal cyclic animals at day 11 of the estrous cycle and other samples were taken from 20 postpartum anestrus animals. Gyneco-clinical and ultrasonographical examinations were performed for confirmation of cyclic and anestrus condition after calving. Anestrus animals had a significant reduction in serum progesterone (P4), estradiol (E2), thyroxine (T4), triiodothyronine (T3), total cholesterol, phosphorus (P) and zinc (Zn). Nonetheless, blood glucose, protein, triglycerides, HDL - cholesterol, calcium (Ca) and copper (Cu) levels did not vary between regular cyclic and anestrus condition. In conclusion, these findings may improve our understanding of some aspects related with postpartum anestrus buffalos which may lead to better procedures for reproductive management.
