Studies in the field of goat breeding have shown that the most widely used and effective way to induce and synchronize estrus in the breeding season is the hormonal method with Chronogest sponges and the administration of Folligon and a prostaglandin. In the present study, we looked at the reproductive performance of a batch of 148 Alpina goats synchronized in April with Chronogest sponges maintained intravaginally for 11 days and the injection of 400 IU Folligon without prostaglandin administration. Artificial insemination with frozen semen was performed 43 +/- 2 hours after the removal of the sponges and the following reproductive aspects were established: the degree of the cervix opening at the time of artificial insemination, ultrasound diagnosis of 50 days gestation after artificial insemination with the identification of cases of pseud-gestation (4.05%), the rate of calving (56.76%) and prolificacy (310.71%). In farm conditions, specific to our country, the exclusion of prostaglandin administration decreases the risk of abortions by lysis of luteal bodies in possibly pregnant goats at the time of treatment and insemination.
