Induction of oestrus in anoestrus bitches using cabergoline and gonadotropins (eCG, hCG).

摘要

The aim of the study was to estimate the effectiveness of oestrus induction in bitches using cabergoline as well as equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG). The study was performed on 59 mixed breed bitches. 53 dogs were randomly divided into two groups. Bitches from group I (n=28) were administered cabergoline for 21 days. Group II (n=25) was administered with eCG for 10 consecutive days at 20 IU/kg bw. Additionally, on the 10th day of induction, each bitch received 500 IU of hCG. Effectiveness of oestrus induction in groups I and II was 52 and 64%, respectively. In bitches treated with cabergoline, clinical signs of oestrus were similar to signs which were observed in bitches with spontaneous heat. In bitches of group II, oedema of the vulva, vulvar discharge and standing behaviour were not as visible nor as sharp as oestrus signs in bitches from the control group. The percentage of bitches that showed ovulation was 76.9 and 83.3% for groups I and II, respectively..
