Prevalence of fasciolosis in Zambian cattle observed at selected abattoirs with emphasis on age, sex and origin.
The aim of this study was to determine the prevalence and some factors influencing occurrence of fasciolosis in cattle, carried out at selected major abattoirs in Zambia. Of 841 cattle livers inspected and 677 faecal samples analysed, prevalence rates of 53.9% and 48.9%, respectively, were found. Cumulative prevalence of 60.9% (n = 677) was recorded. According to age, no significant difference of infection was found. Female cattle on liver inspection (59.3%) and coprological examination (65.2%) had significantly higher (P < 0.001) rates than males (44.5% and 36.3% respectively). Origin of cattle had a significant influence (P < 0.001) on the prevalence rate. According to fluke egg count classification, 68.5% of cattle had light infection, 20.9% moderate, 4.4% heavy and 6.2% severe. These results indicate that Fasciola gigantica infection is an important condition that leads to high liver condemnations and/or trimmings in cattle tendered for slaughter.
