--- It was conducted an epidemiological study of bovine viral diarrhea (BVD) and neosporosis in 425 cows in production of 37 herds of Mantaro’s Valley-Junín Region, Peru, by ELISA and identifying their risk factors by applying an epidemiological survey. The values of DVB prevalences were: sample 66.33%, praedial 97.3% (36/37) and average/herd 64.78%, Concepción had prevalences average/herd and sample higher, then Jauja, Chupaca and Huancayo; the prevalence of animals persistently infected (PI) with DVB was 5.8%. The values of neosporosis prevalences were: sample 15.29%, praedial 56.76% (21/37) and average/herd 12.76%; Huancayo had the highest sample prevalence and Concepción the highest average/herd prevalence, Jauja registered lower values for both. Were risk factors for DVB: number services/pregnancy (2-3 OR: 3.9 and > 3 OR: 32); repeater cows (OR: 5.5); breeding with guinea pigs (OR: 5.8); wild animals (OR: 3.75); open herd (OR: 2.58); location in Conception (OR: 3.5) and Jauja (OR: 3); being protective factors the breeding with alpaca (OR: 0.08) and birds (OR: 0.2), existing positive association between high prevalences DVB and the presence of repetitive cows, abortions and abnormal births as well as the use of irrigation ditch as drinking water. Were risk factors for neosporosis: placenta retention/metritis (> 3) (OR: 11.7); artificial reproduction (IA or IA/MN) (07 OR:5.), breeding birds (OR: 4.7); high presence of rats (OR: 6.8); use of springs (OR: 3.7) and close to the herd to the towns (OR: 2.8); was protection factor the use of adecuate cattle facilities (OR: 0.26); there was a negative association between seroprevalence of neosporosis and presence of cows repeaters high values , and positive association between cases of abortions and abnormal births with use of water from irrigation ditches. (DVB and neosporosis) co-infection was 8.9% and the exogenous epidemiological risk was most important for neosporosis as endogenous epidemiological risk for DVB. Key words: bovine viral diarrhea, neosporosis, seroprevalence, persistently infected, risk factors
