Serum Gonadotrophin/Serum Gonadotropin (PMSG)

Pregnant Mare Serum Gonadotropin (PMSG) is a pregnancy hormone found in the blood of mares. It is produced in the chorion of mares during early gestation (from day 40 to 140). PMSG does not appear in the urine of mares. Because of its close relationship with the human pregnancy hormone hCG (human chorionic gonadotropin), the hormone is also called equine chorionic gonadotropin (eCG).PMSG is used for the induction and synchronisation of oestrus in farm animals, in particular pigs. Through the administration of PMSG it is intended that the sows come into heat at the same time and the deliveries can take place synchronously. Thus, working processes for piglet producers become more efficient. Other animal species also treated with PMSG include sheep, goats and cows.
