| Popis: | Oestrus induction in various canine breeds was attempted in 32 bitches. A group of 8 bitches were treated 80-160 d following their previous oestrus (G1) whereas a second group of 24 bitches (G2) were implanted 200-590 d following their previous oestrus. The treatment for each bitch consisted in one Deslorelin implant (Suprelorin® 4,7 mg, Virbac, France), inserted subcutaneously in the post-umbilical region. Ovulation, pregnancy rate and litter size were recorded. All bitches came in heat 4.3 ± 1.4 d after implantation (2-7 d). Ovulation was reported in 62.5% in G1 and 87.5% in G2. One bitch refused mating and since no AI was performed, she was not considered for further analysis. Pregnancy was obtained in 25% in G1 versus 78.3% in G2. Mean litter size was 6.7 ± 3.5 puppies (1-14). Luteal failure was suspected in 3 bitches, two that remained non-pregnant and one which aborted 58 d post-ovulation since the owner refused progesterone supplementation. Deslorelin implants can therefore be considered as a valuable alternative to induce fertile oestrus in bitches in anoestrus. Follow-up of the luteal phase is recommended, since some bitches might encounter luteal failure. |
