Synchronization of oestrus in goats with norgestomet


, : Synchronization of oestrus in goats with norgestomet. Problematiche di biologia, fisiopatologia e clinica della riproduzione animale: 25-34

27 Ionica female goats were given 3 mg norgestomet ear implants in Apr. The implants were removed after 14 days, and the females were injected with 400 IU PMSG and 2 mg PGF2 alpha on the day of removal. 20 females exhibited standing oestrus by 24 h after implant removal, and all females by 48 h.

Three twin pregnancies occurred among 24 pregnant swamp buffaloes in which oestrus had been synchronized by norgestomet or norgestomet plus PMSG. There was a [male] and a [female] in each pair of twins in 2 pregnancies, while the other buffalo was...

The possibility of using transrectal ultrasonography for the detection of ovulation was studied in buffaloes exhibiting natural oestrus (n=20) and in those where oestrous has been synchronized after treatment with prostaglandin (n=9) or norgestome...
