Objective. To identify the risk factors associated with the increasing of the probability of bovine abortion enabling the execution of effective control programs. Materials and methods. Abortion in the department of Nariño has prevailed more tan 5%, according to the information gathered by Colacteos in 2003. Risk factors in relation to abortion existence were grouped in infectious and non-infectious source. In order to identify the risk factors, the data gathered through files and record systis was analyzed between 2006-2007. This data reported abortion cases in milk-producing farms. The insufficient information was completed by a survey carried out in every farm including the variables which were rated as risk factors. A case and control study was the design used to identify these factors in which the Odds Ratio for every variable was estimated and then validated with the regression logistic multivariate model. Results. The values obtained for the variables were the shortage of drainage systis with an OR 4.42 (p 0.006) and the shortage of a septic well with OR 5.59 (p 0.033). Conlusions. the variables considered as risk factors were the shortage of drainage systis and the shortage of a septic well.
