The aim of this study was to evaluate the effect of Regumate® product in association with other hormonal products as a method for oestrus synchronization in gilts. The study was carried out between October 2016 – March 2017 in a private unit in Cluj County, and involved 16 gilts, 8 months of age. The synthetic progesterone Regumate was fed daily at 20 mg Altrenogest/gilt for 18 days. For all animals, 24 hours after cessation of progesterone treatment a PMSG hormone (Folligon) was administered (500 IU/gilt). After a rest period (48 hours) gilts received one injections of hCG hormone (Chorulon), 500 IU/gilt. Gilts were checked for oestrus twice daily and were artificially inseminated. Oestrus occurred on average 5 days after completion of treatment. All gilts expressed signs of oestrus between 24 and 30 hours with a mean value of 28.37 hours. Pregnancy rate was 75% after second insemination. The mean value of farrowed piglets was 10.16 and the average number of weaned piglets in was 9.58. Altrenogest, the active ingredient in Regumate® is effective for regulating the oestrus of gilts in commercial pig farms.
