A foam footbath mat for the parlour entrance or exit. Fill it with your footbath solution by bucket or watering can; as the cows walk over it the foam compresses and wets their feet, then soaks the solution back up.
Top it up after about 80 cows. After milking, hang it over a wooden rail and hose it off. Footbath solutions can mark galvanised rails. An envelope that holds the solution in the mat for longer is sold separately.
