Abstract:
The present investigation “Hormonal intervention for improvement of fertility in repeat breeder buffaloes” was undertaken at Veterinary Polyclinic, Guntur and buffaloes presented to Veterinary Hospitals in and around Guntur District of Andhra Pradesh. The study comprised 32 repeat breeding buffaloes with a history of failure to conceive even after three consecutive artificial inseminations (AI) with good quality frozen semen from a fertile sire. GnRH (Group 1 – 10µg of GnRH 8 hours before AI at observed estrus and Group 2 – 10µg of GnRH 8 hours before AI at observed estrus and 13th day of post insemination), whereas, hCG (Group 3 – 1500 IU of hCG 8 hours before AI at observed estrus and Group 4 – 1500 IU of hCG 8 hours before AI at observed estrus and 13th day of post insemination) protocols for enhancement of fertility studied in 32 repeat breeding buffaloes in comparison with normal cyclical buffaloes as untreated control (Group 5). The conception rates of repeat breeding Graded Murrah buffaloes in Group 1, 2, 3, 4 and control group (Group 5) were recorded to be 25.00, 50.00, 62.50, 75.00 and 42.85 per cent, respectively. In, conclusion hCG treatment groups revealed higher per cent of conception rates when compared with that of GnRH treatment groups.
