Description et évaluation des méthodes de gestion de la reproduction dans les élevages ovins du Sud-Est et étude de l'acceptabilité de nouvelles technologies pour détecter, induire et synchroniser les chaleurs en élevages biologiques et conventionnels

Abstract : Sheep have a seasonal breeding activity. So, shepherds need to use reproductive technics in order to provide lamb meat all year. Nowadays, hormonal treatments are the most effective solution to induce and synchronize ovulation. It is also the only method available for a fixed-time insemination. This study is a part of Reprobio project, a national research and development project to develop and test two alternative technologies : the use of male pheromones to induce ovulation and an automatic heat detector. The goal of this internship was to describe methods of reproduction management used by meat sheep farmers of Sud-Est region and to evaluate their receptiveness about these technologies. 22 organic farmers and 25 conventional farmers have answered to a qualitative survey in the form of a semi-structured interview. According the analysis, more than half farmers are in favour to the use of male pheromons. They estimate that it could be a good way to manage birth periods of their sheeps. Organic farmers look like more reluctant about this technology. The automatic heat detector is less well-liked by meat sheep farmers both organic and conventional farmers. Less than one third is in favour of this technology because they think there no interest to use it. To complete these conclusions, a study of the results in other production areas is in progress.
