The present study was conducted in two parts. Part I included ten apparently healthy bovine animals (5 cows and 5 buffaloes). In part II, 34 clinical cases of bovine (19 cattle, 15 buffaloes), mean age 5.54±0.42 years, suffering from intestinal obstruction (n=11), caecal dilatation (n=16) and peritonitis (n=7) were included. In healthy animals, ultrasonographically, strong motility characterised by constantly changing lumen of small intestine was seen. The mean lumen diameter of the small intestine in healthy buffaloes (2.48±0.17) was significantly (p<0.05) higher than that of cattle (1.95±0.12). Duodenum was seen from the right flank to 10th intercostal space (ICS) medio-ventral to the gallbladder and in the dorsal flank region. In all the sick animals clinical, haemato-biochemical and ultrasonographic examinations were conducted. Majority of the animals had single episode of colic, complete anorexia, abdominal distension, absent or reduced rumen motility and loss of defecation with or without passing of mucus. Significant increase in TLC with relative neutrophilia and hypochloraemic hypokalemic partially compensated metabolic alkalosis was recorded, non-specifically, in all the groups of animals. Ultrasonographically, dilated loops of small intestine with ileus were recorded and lumen diameter of more than 4 cm and non-visualization of cecum was associated with intestinal obstruction. Ultrasonographically, scanning of a few dilated along with collapsed loops of small intestines suggested proximal obstruction whereas multiple dilated loops suggested distal obstruction. Ultrasonographic visualization of cecum from the right flank upto 12th ICS is suggestive of healthy cecum in bovine whereas when seen at 11th ICS or cranially suggests cecum dilatation. Exploratory laparotomy from the left flank following evacuation of rumen contents is a versatile approach to diagnose and treat various lesions causing intestinal obstruction. High TLC, high lactate in blood and high total protein in peritoneal fluid are considered as poor prognostic indicators in animals suffering from intestinal obstruction in bovine
