The oesophageal groove is present in newborn ruminants. It is a channel taking milk from the [[Oesophagus - Anatomy & Physiology|oesophagus]] into the [[The Rumen - Anatomy & Physiology|rumen]], [[The Omasum|omasum]] and then [[The Abomasum|abomasum]], bypassing the [[The Reticulum|reticulum]].

*The groove can also be closed in adult ruminants by the administration of drugs, e.g copper sulphate, which is of use to prevent drugs becoming diluted in the forechambers. Instead, it directs the drugs directly to the [[The Reticulum|reticulum]].
