The aim of this study was to investigate the ultrasonographic reticular features in normal and hardware diseased buffaloes. The study was conducted on 20 apparently normal and 85 hardware diseased buffaloes. Transcutaneous ultrasonography was performed in standing buffaloes without sedation. The area from 6^th to 8^th intercostal space was examined with a 3.5-5 MHz convex transducer. The ventral aspect of the thorax on the left and right of the sternum as well as the left and right lateral thorax up to the level of elbow were examined. Buffaloes with local peritonitis, abdominal and thoracic abscesses, traumatic pericarditis and pleuropnemonia exhibited significantly lower frequency of reticular contractions than the control. There was a significant increase of reticular thickness between buffaloes with traumatic pericarditis, local peritonitis, abdominal and thoracic abscesses and normal buffaloes. The distance between reticulum and abdominal wall was significantly higher in hardware diseased than normal buffaloes. There was a significant difference in the durations of 1^st, 2^nd and total reticular contractions and the relaxation period were significantly longer in buffaloes with traumatic pericarditis (except the 1^st. contraction), local peritonitis, abdominal and thoracic abscesses than healthy buffaloes. Buffaloes with traumatic pericarditis, local peritonitis, abdominal and thoracic abscesses had significantly lower amplitude of 1^st reticular contraction than the normal buffaloes. Buffaloes with all recorded complications of hardware disease had significantly lower amplitude of 2^nd reticular contraction than healthy buffaloes. In conclusion, ultrasonography provides exact information concerning the reticular features in the various complications of hardware disease in buffaloes.
