Abstract
Liver abscesses considered a major economic problem and there exists very less information in association with liver abscesses in bovine. Although studies in several countries have reported on the incidence of bovine liver abscesses at abattoirs, few surveys have identified the etiology and pathological characteristics of liver abscesses. The present study was conducted to evaluate the prevalence of liver abscesses in cattle in Karbala province in Iraq, during the interval which extended from July 2014 to April 2016, the livers of 125 animals in both sexes aged from 1st to 8th years were slaughtered in at the Karbala abattoir, the prevalence of liver abscess was high in cattle aged four years (24%) while Sexes of animals were showed highly significant differences prevalence was high in female (68%) than male (32%). Also the gross evaluation of hepatic lesion according to liver abscess score showed high prevalence of score (A+) (70%) while the histopathological examinations of abscessed liver were observed abscess foci surrounding by the pyogenic membrane.
Highlights
The liver abscesses are one of the most challenging problems for the feedlot industry (Nagaraja and Lechtenberg, 2007)
The high prevalence of liver abscess in cattle fed on a mixture of dry-rolled corn and dry-rolled wheat compared to dry-rolled corn alone (Stock et al, 1990)
The gross examination of 125 were obtained from cows after slaughter have been showed multiple nodules varies in size which scattered on the hepatic surface as large nodules have sized about 0.5-1.5 cm which surrounded by thick membrane containing thick creamy or white-green pus or small abscess scattered in hepatic surface or within the parenchyma of liver, these nodules sized about 0.2 cm in diameter which filled with white yellow pus
Summary
The liver abscesses are one of the most challenging problems for the feedlot industry (Nagaraja and Lechtenberg, 2007). The prevalence of liver abscess in cattle has been ranged 12-32% in slaughtered animals but can be at low percentage 1% to 2% to a high percentage 90% to 95%, but averages 20% to 30% in most feedlots cattle in individual groups. Liver abscess has been considered the major economic problem which responsible of contaminating livers which are associated with less feed intake, weight gain, and dressing percentage. They increase trimming and as a consequence damage the profitability of feedlot producers and slaughter plant owners (Nagaraja and Lechtenberg, 2007)
