Abstract:
The present experiment was conducted in summer months on thirty six crossbreed cows between 1st to 6th lactation that had not been detected in oestrus 6 to 24 months after parturition but having normal genital with sound health, maintained under rural management system. The aim of the present study was to evaluate the response of postpartum anestrus cow to progesterone implant and PGF2α on oestruos cyclicity. All the animals were divided in six groups having six animals in each group. Animals of group I received normal saline solution (2ml, I/M) on day 5 and day 15 and they served as control. The animals of groups II were received 1ml Duraprogen TM (250 mg progesterone) I/M after prostaglanding injection. Animals of group III received 1st first dose of 1ml Duraprogen TM on day 5 and second dose of 1ml Duraprogen TM on day 15. Animals of group IV were received 2ml Duraprogen TM (500 mg) progesterone) on day 5 after prostaglandin injection while the animals of group V were received 1st dose of 2 ml Duraprogen TM on day 5 and second dose of 2ml Duraprogen TM on 15 respectively. Animals of group VI received 3 ml Duraprogen TM (750 mg progesterone) I/M on day 15 after Fenbendazole administration. For the animals of group of VI Prostaglandin (Lutalyse, 25 mg) was administered 8th day after Duraprogen TM administration. Blood samples were collected from each animal on day 0 just before PGFadministration and on day 5, day 15 and day of oestrus in group I to V and from the animals of group VI on the day of progesterone and prostaglandin administration and on day of oestrus. None of the animals in control group was detected in oestrus while one animal of group II, six animal of group V and two animal of group VI were detected in oestrus 2 to 16 days after the last duraprogen injection. It was concluded that the crossbred cows having normal genitalia and sound health can be brought in to fertile oestrus during summer months by a combined treatment with 25 mg prostaglandin and 500 mg to 750 mg progesterone.
