In: Mansoura Unviersity Journal of Agricultural Sciences 2005.v.30(4)Summary: The aim of this study was to compare the accuracy of five different methods to diagnose pregnancy in sheep. A total of 466 of crossbred (Finnish x Rahmani) ewes were mated naturally in September (n=382) and May (n=84) mating season. Serum P4 concentrations at day 18 after mating were determined by RIA test. The ewes which showed blood P4 >1 ng were considered pregnant. Based on lambing data, the accuracy for diagnosing pregnant (positive) and non-pregnant ewes (negative) were 96.59 and 100% at day 18, respectively. By day 30 after breeding, an accuracy of 80 and 94.2% has been obtained for pregnant ewes using non-return to estrus as pregnancy diagnostic method at May and September mating season, respectively..
