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

==Function in the Adult Ruminant==

==Function in the Adult Ruminant==

The groove is stimulated in adult ruminants by ADH. 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 [[Reticulum - Anatomy & Physiology|reticulum]].
