TAILIEUCHUNG - Synchronisation of oestrous in stall fed Malnad gidda cattle: A comparative study

Number of estrus synchronization programmes is available in cattle with hormones combinations of PGF2α, Gonadotrophin Releasing hormone (GnRH), and Leutinizing Hormone (LH). Comparative study of different estrus synchronization protocols in Malnad Gidda cows was done in stall fed Malnad Gidda cattle. The study was conducted in stall fed cattle with repeat breeding. Group I served as control in which the animals were artificially inseminated whereas the group II animals received a treatment of GnRH on day 0, PGF2α on day 7 followed by administration of another dose of GnRH on day 9 and AI on day 10. The group II animals were administered with first dose of GnRH on day 0, a dose of PGF2α on day 7 and a dose of hCG on day 9 followed by insemination on day 10. Whereas, the group III animals administered with two doses of PGF2α on day 0 and day 11 after palpation of active CL. On day 13 GnRH was administered and on day 14, the insemination was done. The conception rate was, in control group, group I, group II and group III, conception rate was of , , per cent respectively. The present study revealed the synchronization of oestrous give the better conception rate. | Synchronisation of oestrous in stall fed Malnad gidda cattle: A comparative study
