title: Left abomasal displacement between the uterus and rumen during bovine twin pregnancy.
abstract: Here, we describe two cases of left displaced abomasum (LDA) in Holstein cattle at 6 and 9 months of twin gestation. Clinical examination revealed signs of proximal ileus with marked abdominal distension, but no ping sounds. An unusually high position of the gravid uterine horn on the left side was bserved with ultrasound. Left exploratory laparotomy confirmed that the abomasum was displaced to the left and entrapped between the rumen and twin gravid uterine horn. A left surgical approach was necessary to correct the condition. Both animals recovered and gave birth to healthy twins. The present cases indicate that the subomental position of a heavy twin gravid uterine horn is a possible mechanical cause of LDA.
