Abortion rates vary between 2 and 20 % and there is little information regarding non-infectious factors affecting fetal stages. We analyzed the joint relationship of infectious and non-infectious factors with the probability of abortion in dairy cows. We used dairy cows from the Ñuble province of Chile (n = 148) at 42 days of pregnancy. We then took monthly blood samples until abortion or calving. We determined plasma concentrations for the following: amino transferase, albumin, cholesterol, globulin, fibrinogen, â-hydroxybutyrate, retinol, á-tocopherol, calcium, phosphorus, glutathione peroxidase, total proteins and urea. Serology was performed for infectious diseases and body conditions were recorded. Our study used a multivariable logistic regression model and proportional hazard regression. There was an (p < 0.05) association with abortion, (or = 4.27) for <em>Neospora caninum </em>and (hr = 94.35) for <em>Leptospira interrogans</em>, with a low cholesterol concentration (p < 0.05) in the fourth month of pregnancy (or = 0.61), and a decrease in body condition from month three to four (or = 0.32). bas is associated with negative energy balances, protective effects of high cholesterol plasma concentrations in the first trimester of gestation and incidences of <em>Neospora caninum</em>, <em>Leptospira interrogans</em>, and a conjunction of the two. It is important to provide epidemiological surveillance tools that help anticipate herd reproductive losses through management measures, infectious disease control and proper nutritional management.</p>}, journal={Veterinaria México OA}, author={Gädicke L’Huissier, Paula and Chihuailaf, R and Letelier, R and Allende, R and Ruiz, A and Junod, T}, year={2022}, month={Jun.} }
