Online published on 7 October, 2016. Abstract The present study was carried out on 33 apparently healthy cattle (n=17) and buffaloes (n=16). Out of which, 12 were non/early pregnant cattle; 5 were advance pregnant cattle; 11 non/early pregnant buffaloes; 5 advanced pregnant buffaloes. Ultrasonography was carried out on the right side from 4th to 12th intercostal space (ICS) and left side from 4th to 7th ICS with a 3.5/5.0 MHz convex probe. In apparently healthy non/early pregnant cattle, cranial most part of the reticulum was seen at 5th ICS from the right (83.3%) and left sides (75%), whereas in apparently healthy non/early pregnant buffaloes, it was seen at 6th ICS only. In all advance pregnant cattle and buffaloes, reticular wall was seen at 5th ICS from both the sides. The upper border of the reticulum on the right side, at each ICS, was more dorsally located as compared to the left, irrespective of species and pregnancy. The omasum was consistently visualized at the 8th and 9th ICS in all the animals irrespective of species and pregnancy. However, it had more cranial location in cattle (6th to 10th ICS) compared to buffaloes (7th to 11th ICS). Mild omasal motility was appreciable in 4 cattle and 5 buffaloes only. Majority of the animals had omasum size up to 4 ICS. It was concluded that in cattle, irrespective of pregnancy, and in advance pregnant buffaloes, reticulum is normally seen at the 5th ICS. There was no influence of species and pregnancy on the size of the omasum but advance pregnancy can lift the omasum dorsally in cattle and buffaloes.
