Synchronization of oestrus and ovulation in sows using placental gonadotropins


, : Synchronization of oestrus and ovulation in sows using placental gonadotropins. Nauchnye Osnovy Razvitiya Zhivotnovodstva v BSSR (17): 15-18

160 placentas from sows 6-12 weeks pregnant yielded 5000 mg FSH and 400-900 mg LH/kg raw placenta; the activity of FSH was 1 IU/mg and that of LH was 10 IU/mg.

Data on 49 gilts (13 with spontaneous oestrus) and 40 sows (all with induced oestrus and ovulation, using PMSG + HCG treatment) were analysed. The ovulation rate averaged 14.7 and 17.7 for non-induced and induced gilts resp., and ranged from 17.0...
