Principal Investigator: Jillian Gordon. Dairy cattle have the potential to be affected by poor dental health more than other farmed ruminants. This is because dairy cattle are fed a high concentrate, high preserved forage diet both of which are acidic. It is not known how much pain dairy cows may suffer during dental disease, nor is it known how this effects their behaviour or production levels. This research project aims to pilot a grimace-scale using soon-to-be culled dairy cows in combination with post-mortem dental health investigation, to determine if these cattle have dental problems and if this is something that can be identified while they are alive.
