A Biofilm is an often invisible community of bacteria which can build up on any equipment or surface. Many species of bacteria can form in a biofilm and this can play a significant role in harbouring and transferring pathogens.

A biofilm is usually undetectable by eye, however an extreme build up may cause a yellow or white scum to appear.


Even low levels of the wrong bacteria can cause a calf to scour. persistent scour is both detrimental to both calf health and long term performance.
