Pregnancy termination in bitches during early pregnancy with antiprogestin (Aglepriston-AlizinReg.).

摘要

10 mismated bitches, <8 years old, were treated at the Clinic for Obstetrics and Reproduction, Faculty of Veterinary Medicine, University Zagreb, between January and April 2002. Owners confirmed that the bitches were bred and demanded pregnancy termination. Sperm was found in vaginal smears in 7 out of 10 bitches after two days of breeding. More than 80% superficial cells in vaginal smear cytology confirmed the oestrus in all 10 bitches. On day 15 after breeding, all bitches were passed gynecological examination and antiprogestin aglepristone (Alizine) was administered at a dose of 10 mg/kg body weight (0.33 ml/kg). Equal dose was administered in 24 h later. Abdominal ultrasonography 20 days after the treatment did not confirm any pregnancy.
