This study was conducted to investigate the ultrasonographic findings of diaphragmatic hernia (DH) in buffaloes. Each 10 of healthy non pregnant, pregnant and buffaloes with DH were investigated. The most observed signs of DH were dullness, depression, inappetence, tympany and scanty feces. Reticulum of all buffaloes with DH was detected at the level of 4th/5th intercostal space (ICS) by ultrasonography. Contraction manner was either biphasic (n=6), monophasic (n=2) or non-motile (n=2). Contraction frequency was either reduced (n=6), normal (n=2) or increased (n=2). Also, hypoechoic inflammatory adhesion was found between reticulum and thoracic organs (n=6). Herniated reticulum was imaged beneath lung (n=6) and beneath heart (n=4). Hemato-biochemical analyses revealed significant elevations in total leucocytes, total protein, globulin and fibrinogen in comparison with control groups.  Collectively, not only ultrasonography of DH in buffaloes was based on reticulum location at 4th/5th ICS, but also other investigations should be evaluated.
