OCHOA, Ximena et al. Seroprevalence of infectious bovine rhinotracheitis in dairy herds Toca - Boyaca. Rev.MVZ Cordoba [online]. 2012, vol.17, n.2, pp.2974-2982. ISSN 0122-0268.

Objective. Determining the Seroprevalence of infectious bovine rhinotracheitis (IBR) in dairy herds in the municipality of Toca - Boyaca. Materials and methods. 80 blood samples were collected from female cattle that were in production or, that had a delivery reported in their charts, specifying data on each one of them: identification, age, number of deliveries, reproductive problems they presented as well as the types of reproductive impairments present. Serum samples were processed to determine the presence of antibodies of the disease. Results. The seroprevalence of IBR in the municipality of Toca - Boyaca, was of 35.65%, distributed as follows: 17.9% in specimens between 24-60 months, 60.7% in animals of 72-108 months and 21.4% in animals older than 109 months; the test was positive in 32% of cows with reproductive problems (n = 8), a history of abortion and positive test was reported in 1.25% (n = 1) of the sample. Conclusions. This work constitutes the first report of analysis of this disease in the municipality of Toca-Boyacá, demonstrating the presence of disease in the area. Concurrently, it suggests that this condition may be one of the possible risk factors affecting the economic profitability of dairy production.
