This study aimed to determine whether combination of the controlled-internal drug releasing device
(CIDR) within or before ovsynch protocols in acyclic postpartum buffaloes improves both the resumption of cyclicity
and conception rate compared to ovsynch protocols only. Thirty-one clinically healthy female buffaloes (3-5 yearsold; and 440.0± 10.0 kg b.wt) suffering from prolonged postpartum anestrous (3-9 months) were included. Buffaloes
with any disorders that may directly or indirectly affect reproductive performance were excluded. Blood sampling was
performed at these time-points; day -10, 0, 4, 7, and 9. Plasma progesterone and phosphorus (P) were assayed. Our
results showed that the conception rate was significantly higher (P<0.05) in the GPG ovsynch-treated compared
to the G-CIDR-PG but not the CIDR-GPG modified ovsynch-treated modified with conception rates of 57.1%,
30.0%, and 50.0 %respectively). This study found that, the P concentrations were significantly higher in the responsive
compared to the non-responsive CIDR-GPG-modified ovsynch-treated group. This study concluded that GPGovsynch would be beneficial for synchronization in postpartum buffaloes. Moreover, CIDR-GPG likely improve the
fertility, since the higher P levels can be utilized in activating the follicular dynamics
