Prevalence and economic importance of Fascioliasis in cattle, sheep and goats in Kenya.
journal. : University of Nairobi Press Abstract
A 10-year (1990-1999) retrospective study using post mortem records was carried out at veterinary Department Headquarters Kabete to determine the prevalence and economic importance of fasciolosis in cattle, sheep and goats in Kenya. Records from abattoirs from 38 districts in 7 provinces of Kenya were examined. Fasciolosis prevalence was calculated using an average weight of (3kg) for cattle and (0.5kg) for sheep and goats. The monetary loss occasioned by condemnation of Fasciola infected livers was calculated using and a market price of US$ 2.0 per Kg. Out of 5,421,188 cattle, 1,700,281 sheep and 2,062,828 goats slaughtered, 427,931 cattle (8%), 61,955 sheep (3.6%) and 48,889 goats (2.4%) were infected with Fasciola. The highest prevalence was recorded in Western province (16% for cattle, 10% for sheep and 9% for goats). The lowest was in Coast province (3.5% cattle, 0.74% sheep and 0.5% goats). The economic loss due to condemnation of infected livers from cattle, sheep and goats was estimated to be US$ 2.6 million, US$ 61,955 and US$ 48,889 respectively. It was concluded that fasciolosis is prevalent in cattle, sheep and goats in Kenya and is a major cause of economic loss, as a result of condemnation of infected livers.
