Induction of estrus in anoestrus bitches using cabergoline and gonadotropins (eCG, hCG) |
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 a total number of 59 mixed bitches. The 53 canines were randomly divided into two groups. Bitches from group I (n = 28) were administered cabergoline for 21 days. In group II (n = 25) eCG was administered for 10 consecutive days in a dose of 20 I.U. per kg. b.w. Additionally, on the 10th day of induction each bitch received 500 I.U. of hCG. Effectiveness of estrus induction in group I was 52%, while in group II 64%. In bitches treated with cabergoline, clinical signs of estrus were similar to signs which were observed in bitches with spontaneous heat. In bitches of group II, edema of the vulva, vulvar discharge and standing behavior were not as visible nor as sharp as estrus signs in bitches from the control group. Percentage of bitches with ovulation was in group I 76.9% and in group II 83.3%. |
