All other approaches up until now use batching- you make a footbath and run a batch of cows through it. The issue with batching, however, is that the first cow gets a good treatment while the last cow gets nothing. Batching was originally developed when herds were too small to destroy footbath chemistry, so this approach does not work efficiently for large herds.
When a bath needs to be emptied, cleaned, and refilled after a batch of cows, it can cause serious disruptions to cow traffic, ultimately resulting in a slower milking process.
Current ways of running a footbath only allow for the first cows in a large group to receive an adequate footbath. The Hoofbath Tender system would reduce the lameness rate within a herd.
The old batch bath system must be filled 50% too deep in order to last through a large herd. This results in excessive spillage which wastes an enormous amount of chemicals.
The bath cannot be made consistently well between groups by a cow pusher who is rushed.
