Attempts to automatically disinfect teats after milking has had mixed results depending on the system used. '''Automatic spraying bars''' are located at parlour exits and work by detecting cow movement over the bar and directing the spray towards the udder. However, they often do not achieve adequate coverage. Their location outside the parlour also delays the application of the disinfectant compared to manual within parlour methods. The bar may also affect cow flow exiting the parlour, particularly for cows unaccustomed to its presence (i.e. heifers and bought in animals). Cows that resent its presence often rush over the bars meaning effective coverage is very unlikely. A further disadvantage is that their function may be difficult to monitor from the parlour (e.g. running out of solution during milking).

The use of [[Automatic Disinfection and Flushing (ADF|Automatic Disinfection and Flushing (ADF)]] systems is becoming increasingly popular and appears to be highly effective at limiting the spread of contagious pathogens in the parlour.
