An additional five farms that did not alter their standard hoofcare routine were also included. These dairies averaged 143 cows and a prevalence of active digital dermatitis (DD) lesions (hairy warts) of 15%.

For the QAC group, chronic DD lesion prevalence decreased at the same rate for weeks 0\u20136, but then leveled off between 6 and 12 weeks. The QAC treatment also did not decrease the proportion of cows with active DD lesions. The researchers concluded that QAC was inferior to CuSO<sub>4<\/sub> for footbath control of hairy warts. This is unfortunate, as a viable alternative to CuSO<sub>4<\/sub> would be useful to reduce the amount of copper that ends up in pastures and crop fields (via manure handling and application systems).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a Canadian study published in the July 2017 issue of Journal of Dairy Science, researchers compared a quaternary ammonium compound-based (QAC) footbath to a more conventional copper sulfate (CuSO4) footbath.
