This study was conducted to estimate the influence of season of lambing on the postpartum interval to return of ovarian activity, conception and subsequent lambing (lambing interval) among 78 Djallonke ewes reared on-station in the Guinea Savannah zone of Ghana. Serum progesterone measurements were used to determine the postpartum return to ovarian activity for ewes lambing in two major seasons; the rainy and dry seasons. The results showed that Djallonke ewes resumed ovarian activity 63.7±2.7 days postpartum and conceived by 97.4±4.2 days postpartum, achieving a mean lambing interval of 249 days. Ewes lambing in the rainy season resumed postpartum ovarian activity significantly earlier than their counterparts lambing in the dry season (55.1±4.1d vs 71.5±3.2d, respectively) (P
