The objective of this study was to compare the efficiency of different estrus induction protocols in anoestrus goat. Does were assigned to seven groups (A-G). In the group A, the animals (n=25 ) received intravaginal sponges containing 30 mg of flugestone acetate FGA (Chronogest, Intervet) for 12 days and i.m. injection of 500 I.U. of PMSG (Folligon, Intervet) two days before sponges withdrawal. In the groups B(n=10), C (n=10), D (n=10) females received 12,5 mg progesterone (Progesteronum, Polfa Warszawa S.A.) per animal in i.m. injections respectively for 6, 12 or 2 days. Females from groups E (n=10) and F (n=10) received altrenogest (Regumate, Intervet) p.o. for 6 or 12 day. At the end of progestagen treatment the animals from group B, C, D, E, F received 500 I.U. of PMSG i.m. The goats from control group G (n=10) did not received any treatment. During the experiment, a significant difference was found in the effectiveness of the oestrus induction among applied methods. Oestrus occurred in 72% of females from group A, 60% from group B, 100% from group C and 20 % of females from group G. Oestrus was not observed in any female of group D, E and F. We concluded that the duration of the progestagen treatment significantly influenced the efficiency of the oestrus induction protocol in anoestrus goats.

Celem pracy było porównanie skuteczności różnych protokołów indukcji rui u kóz poza sezonem rozrodczym. Samice zostały podzielone na siedem grup (A-G). Zwierzętom z grupy A (n=25) zaaplikowano gąbki dopochwowe zawierające 30 mg octanu flugestonu FGA (Chronogest, Internet) na okres 12 dni oraz 500 I.U. PMSG (Foligon, Inter- vet) w postaci iniekcji domięśniowej na dwa dni przed usunięciem gąbek. Samice z grup B (n=10), C (n=10) oraz D (n=10) otrzymywały domięśniowe iniekcje 12,5 mg progesteronu (Progesteronum, Polfa Warszawa S.A.) odpowiednio przez okres 6, 12 oraz 2 dni. Kozy z grupy E (n=10) oraz F (n=10) otrzymywały per os altrenogest (Regumate, Intervet) przez okres 6 lub 12 dni. Ostatniego dnia administracji progesteronu/progestagenu samicom z grup B, C, D, E, F podano 500 I.U. PMSG i.m. Grupę kontrolną stanowiły samice z grupy G (n=10), u których nie stosowano żadnych środków hormonalnych. W toku eksperymentu stwierdziliśmy istotną różnicę w skuteczności indukcji rui u kóz pomiędzy poszczególnymi programami. Pełnowartościowa ruja wystąpiła u 72% samic z grupy A, 60% z grupy B, 100% z grupy C oraz 20% z grupy G. W grupach D, E, oraz F nie odnotowano ani jedne­go przypadku rui. Uzyskane wyniki wskazują na istotność długości stosowania programu opartego na podawaniu progesteronu na skuteczność wywoływania rui u kóz poza sezonem rozrodczym.
