Abstract
An active cross-sectional abattoir study was conducted to assess the prevalence, types and associated factors of liver lesions in sheep and goat at the Suame Abattoir in Kumasi- Ghana. A total prevalence rate of 13.2% liver lesions was recorded with a 7.3% and 5.9% prevalence rate in sheep and goats respectively. Liver abscess was recorded in 80.71% pathologic liver samples followed by liver fibrosis (5.71%), calcified cysts (2.86%), liver putrefaction (2.14%), liver cirrhosis (2.14%), melanosis (2.14%), hydatid cyst (1.42%) and fatty infiltration (1.42%), hepatitis (0.71%) and liver with urate deposits (gout) (0.71%). More liver lesions were found in the West African Dwarf Sheep (WADS) (54.5%) as compared to the Sahelian breed (45.5%) of sheep. The West African Dwarf Goat (WADG) had a higher occurrence (76.2%) of liver lesions than the Sahelian (23.8%). Female sheep and goats had higher occurrences of liver lesions as compared to the male. The adult (> 2 years) sheep and goats had more liver lesions compared to the young (< 2 years). Sheep and goats with good body condition score recorded higher liver pathologies with more recorded in the dry season. The differences in occurrence of liver lesions with respect to species of small ruminant was statistically significant (p < 0.05) whilst that of breed, sex, age and season of occurrence were not significantly different (p >0.05). Good animal husbandry practices should be employed to lower the incidence of liver pathologies in small ruminants. Expert policies to trace back to towns of origin of small ruminants that present with liver diseases should be put in place by the abattoir
