Epidemiological Survey on Abortions in Domestic Ruminants in the Governorate of Biskra, Eastern Arid Region of Algeria

Abortions in ruminants can have several causes. A very few studies were realized in Algeria about abortions in domestic ruminants. The aim of this study was to collect necessary epidemiological data concerning observed characteristics of abortions in ruminants of the governorate of Biskra. Therefore, we elaborated a field investigation using a questionnaire, that touched 31 private veterinary practitioners. Statistical analysis was performed by SPSS software. Results showed that the most observed frequency of occurrence of abortions is « many per annum » (45.2 %). Autumn was mentioned as the highest risk period of abortions in ruminants. The most observed epidemiological form of abortions is (Enzootic in herds with epizootic pics) ; (41.93%).The pregnancy stage of high risk of occurence of abortions is (Tound trimester) ; (58.06 %). Chisquare test showed a high positive significant correlation (r = + 0,03) between the variable « region » and the variable « frequencies of occurrence per annum ». Abortive causes in ruminants are so various, and with no specific symptoms in the main time. Generally, epidemilogical data are not sufficient to a full diagnosis. Techniques with high specificity and sensibility as PCR and ELISA should be widespread.
