Abstract


The study was carried on 1425 ewes Transilvanian Merinos sheep in the farm belonging to SC Sinnagro SA, Timis country, regarding the reproduction during breeding season and in extra- season. The investigation revealed that these sheep held in good condition do express estrus (88%) during spring-summer (May-June) and are lambing during autumn (82%) with a lower prolificacy (109%). During fall, almost all sheep (98%) displayed estrus, lambing in a proportion of 94,8%, with a prolificacy of 127,1%. The statistical analysis emphasized that all reproductive indexes are higher (p<0.01) subsequent to breeding during normal season, compared to the extra-season, excepting fertility. These findings suggest that Transilvanian Merinos sheep are suitable for generating autumn lambs, for which does exists a great demand abroad.
