Minas Gerais (MG) State stands out in dairy goat with other states in the Brazilian Southeast Region. As the demands are specific, properties should be analyzed considering its profile, beef or dairy; intensive or subsistence production. Determining the prevalence according to the profile of commercial beef and dairy properties as small ruminant lentivirus (SRLV) enable the proposition state program for control of small ruminant lentiviruses. This study aimed to determine the SRLV seroprevalence in commercial goat herds in Minas Gerais, in 2011, considering the productive typology. Rating variables that has influence on SRLV seropositivity and characterize the properties with emphasis on SRLV. The sampling was performed in 70 commercial properties, 10 for beef and 60 for milk, in 12 MG regions. The 1400 serum was analyzed by the agar gel immunodiffusion test (AGID) and variables were obtained through epidemiological questionnaire. The prevalence and frequencies of variables were calculated based on IDGA results for the presence of SRLV infection. The overall prevalence in commercial goat herds was 13.8 % (202/1400), and when we consider the typology production, prevalence increased to 23 % (202/1194) in dairy goats and 0 % (0 / 206) in beef goats. The prevalence in commercial properties with at least one seropositive goat for SRLV was 81.4% (57/70) and 95% (57/60) in dairy properties and null (0/10) in beef properties. The prevalence increased with age, but it was not altered based on breed, gender and degree of blood. In 55.0% (33/60) is made of the properties some form of control for CAE in the herd, and of this 93.9% are positive for SRLV, demonstrating that failures occur in the control measures taken. The properties characterized by dairy feedlot perform collective management practices that favor the spread of SRLV, requiring the adoption of appropriate control measures. The cutting properties, zero prevalence, need for prophylactic measures to prevent introduction of the virus.
