Add Tag | Summary: | The Bovine Viral Diarrhea Virus (BVDV) is one of the pathogens of worldwide distribution that affects domestic and wild ruminants causing economic losses due to transplacental, respiratory and digestive tract infections. The objective of this research is to determine the prevalence of Bovine Viral Diarrhea using the ELISA-i technique in the cantons of Latacunga, La Maná and Sigchos in the Province of Cotopaxi. The number of samples to be collected was 465 cattle of which 224 samples were distributed proportionally, corresponding to the rural parishes of the aforementioned cantons. Blood samples were taken for analysis, after which serum was extracted and the BVD Elisa kit was performed. The Chi-square test (χ²) was used to test hypotheses referring to frequency distributions of each of the variables obtained; also to identify if there is a relationship between the risk factors with the presence of the disease, in which the results were determined with the help of tables and charts. The results show a total prevalence of 14.73% distributed among the three cantons, with the highest prevalence found in the canton of Latacunga with a percentage of 10.26%, followed by the canton of Sigchos with 4.01% and finally the canton of La Maná with 0.44%, which had a low number of positive cases compared to the other cantons. Regarding the risk factors studied, it was determined that age (cattle > 4 years old) was associated with a prevalence of 8.92% with 20 positive cases; in the case of sex, a greater number of positive cases were detected in males, 36 with a prevalence of 16.07% compared to females, giving a low number of positive cases and a prevalence of 2.23%. Finally, the breed factor showed a higher prevalence of 13.83% and 31 positive cases corresponding to the Holstein breed. |
