Abstract
Background and aim: Liver
abscesses in feedlot cattle have a major economic impact in the
beef industry because of liver condemnation and reduced animal
performance and carcass yield. The aim of this study was to
document the clinico-pathological and ultrasonographic findings in
cattle and buffaloes with hepatic abscess.
Materials and Methods: Three male feedlot cattle and 5
buffaloes suffered from liver abscesses were investigated.
Clinical, hemato-biochemical and Ultrasonographic were performed.
Liver abscesses were confirmed through centesis and aspiration
under ultrasonographic guidance which yield purulent material.
Necropsy and histopathological studies were applied on 3 of them,
where ultrasonographic diagnosis was confirmed.
Results: Altered appetite, loss of body weight, dull
demeanor and decreased ruminal motility were recorded in all eight
animals. Systemic disturbance and feces abnormalities were
appeared with variable degrees. Icterus and abdominal pain were
observed only in one cattle. Leucocytosis, hypoalbuminaemia and
hyperglobulinaemia were reported in all animals while liver
enzymes were mildly elevated only in 3 cattle and one buffalo.
Abscess appeared by ultrasonography as hypoechoic to echogenic
circumscribed mass, pinpoint to 10 cm in diameter, with or without
echogenic wall, located in the right lobe 7th to 12th intercostal
spaces. Abscesses were located intra-hepatic in 7 (3 cattle and 4
buffaloes) animals and peri-hepatic (between liver and reticulum)
in one buffalo.
Conclusions: Ultrasonographic results were of considerable
value for ante-mortem diagnosis of hepatic abscesses.
Keywords: abscesses, buffaloes, feedlot cattle,
histopathology, liver, ultrasonography.
