The abortion rate for small ruminants is usually estimated at 5%. In Belgium, for example, there is no systematic abortion census for this sector and this figure is currently difficult to confirm. According to the most recent studies on abortions of small ruminants, the notion of multifactorial has been put forward and the value of a differential diagnosis of abortion causes has been noted. The preface of this study lists the infectious and non-infectious causes of abortion in Belgium. For each factor, the means of transmission, the risk of zoonosis, the clinical signs, the diagnostic tests, the treatment and prevention have been analyzed. The originality of this work lies mainly in the fulfilment of an online questionnaire sent to small ruminant breeders. The aim of this questionnaire is to asses the situation with regards to abortion in this sector in Belgium. This study is a first and had never been carried out before. The analysis of the results of this study has enabled us to establish the profile of small ruminant breeders in Belgium (Wallonia), to give an estimate of the number of abortion cases, to know the feeding behaviour as well as the biosecurity and sanitary measures followed by the breeders. All these factors were analyzed in order to identify possible causes explaining the abortion rate. This study also revealed the measures that would be judicious to implement in order to increase diagnosis and in the long term to reduce the number of abortions in Belgium. ; Questionnaire: Gestion des avortements chez les petits ruminants (ovins-caprins).
