This syndrome appears to be closely related to a gall bladder displacement syndrome (GBD), with obstruction and dorsiflexion of the sigmoid flexure. I operated on two DSFV cases and one GBD case between April and June 2012 and have operated on three DSFV cases and one GBD case between April and July 2013, with three more DSFV cases being found by colleagues during the same period of 2013.

Cows with DSFV typically present with agalactica, anorexia, ventral rumenal and abomasal distension, and moderate to severe dehydration. Ataxia, bruxism, reluctance to rise, lack of faeces in the rectum and nasal reflux of rumen fluid appear common in the later stages. Cows with DSFV exhibit tachycardia and a focal area …
