RESUMEN
We aimed to follow the epidemiologic evolution of bovine digital dermatitis (BDD) and other podal diseases grouped in a dairy farm in Central Brazil between the years 2010 and 2016. This study was carried out in a farm in Jataí, Goiás, Central Brazil, where the prevalence data of bovine digital dermatitis (BDD) and other podal diseases, as well as the composition, history, and management of the herd, was collected. We analyzed the collected data into the two annual pluviometric precipitation values in Central Brazil: rainy season and dry season. The cumulative frequency for comparison of prevalence between seasons throughout the years was calculated from 2011 to 2016. The comparison was carried out by post hoc chi-square test with the Bonferroni correction adopting a level of significance of 5% (p < 0.05). BDD was not diagnosed at the property in 2010; however, the disease became endemic from 2011, which coincides with the arrival of new animals to the herd. The comparison of the accumulated frequencies for prevalence of the diseases in the herd between 2011 and 2016 revealed BDD, as well as the grouped nutritional and metabolic foot diseases, has the highest prevalence in the period of lower annual precipitation in Central Brazil, which occurs between May and October. For a better control of BDD, we recommend greater attention in cattle management in the dry season of the year in Brazil, as well as in any other place in the world in which rainfall is seasonal.
