Abstract
There are no published abattoir bovine hepatic lesion prevalence studies in cattle in Rwanda. This studyestimated that 12.3% of the livers (n = 4751) examined at Nyabugogo slaughterhouse in Kigali were con-demned. Condemnation prejudiced the nation of 3492.00 kg of meat with attendant economic losses ofUS$8932.40 during the study period. Risk factors for these lesions were also assessed. Male and femaleanimals from 11 districts were used in this study. Hepatic lesions were higher in females (14.6%; n = 1494)than in males (11.1%; n = 3257). About 78.7% of the condemnations were due to fascioliasis, followed byabscesses (5.7%), hepatitis (5.3%), cirrhosis (4%) and other lesions (6.3%). Female animal livers showedmore fascioliasis and abscesses (82.2% and 9.5%) than male animal livers (73.3% and 3.3%). The high-est rate of condemnation was observed from Kayonza (40.2%; n = 413) and the least was from Gakenkedistrict (0.9%; n = 1031). Cattle from the Eastern Province showed significantly (P < 0.05) higher preva-lence of condemnations (26.8%) than the rest of the provinces. Liver specimens of animals below 3 yearsand above 6 years of age had a significantly higher (P < 0.05) condemnation rate (14.4%) (n = 3000 andn = 769) than the 3–6 year age-group at 4.1% (n = 982). We conclude that fascioliasis was responsible fora significant proportion of the liver condemnations at Nyabugogo slaughterhouse. Being a zoonosis, werecommend an epidemio-surveillance, implementation of control measures and anthelmintic resistanceinvestigation for fascioliasis in Rwanda.
