Abstract
The sheep production constitutes a highly important livestock activity in Europe and other Mediterranean countries. The productivity improvement, and especially of the reproductive parameters is important for the sustainability of these systems. With the aim of characterising the productive situation of sheep systems, information of the most important reproductive parameters has been collected (fertility), gestation efficiency (abortion) and lamb mortality. Technical responsibles from the breeders associations or working improvement programs were contacted, from each of the 20 sheep system of the 7 partner countries. Systems were classified according to their geographical situation (mountain, low land, etc.), reproductive system (1 lambing per year or accelerated strategies), and the productive aptitude (meet, dairy or double propose). A huge variability between productive systems and flock were observed into the analysed reproductive parameters. As well as a generalized data lack, especially those reporting the abortion and lamb mortality rates. The lamb rate per ewe reported is low (<1.5), even into the accelerated strategies. Thus, a big improvement could be done in sheep productivity.
