Many dairy farmers use a range of different footbath solutions to help control lameness, often switching from one to the other with little difference in performance. Many solutions arrive on the market with the promise of treating all lameness problems but fail to live up to expectations. So how do farmers decide what will work against their lameness problems, especially the complex digital dermatitis problem? One option is to listen to other farmers. However as every farm is different often what works on one farm will frustratingly not work on another. Another option is to consider independent peer reviewed scientific evidence.
