Prevalence and financial loss estimation of parasitic diseases detected in slaughtered cattle in Kwara State, North-central Nigeria.

Parasitism is of great concern to the wellbeing, productivity and reproductivity of animals and it causes great financial loss to the economy of any nation. This study was conducted to determine the prevalence and the economic loss from carcass and viscera condemnation due to parasitic diseases in slaughtered cattle in Kwara State, North-central Nigeria. A 16 year (2003-2018) record of parasitic diseases detected in cattle slaughtered at the major abattoirs in Ilorin city was retrieved from the Kwara State Veterinary department of the Ministry of Agriculture and Natural Resources. The total prevalence as well as the yearly, monthly and seasonal prevalence of each of the documented parasitic diseases was determined. The financial losses associated with each of the parasitic diseases were estimated in Nigerian Naira (₦) and US Dollar (USD) considering the market price and weight of viscera condemned. Fasciolosis, hydatidosis, dicrocoeliosis, cysticercosis and oesophagostomiasis were the parasitic disease conditions with fasciolosis (6371/832,001) and cysticercosis (134/832,001) been the most and least prevalent disease conditions respectively. The yearly and monthly prevalence of each disease conditions showed an undefined pattern. There was a significantly difference in the prevalence of the detected parasitic conditions within seasons. The total financial loss associated with these disease conditions was 304,133.82 USD (46,161,433 Nigerian Naira). This study showed that parasitic diseases are of great financial drain to the livestock economy of Nigeria and this study will serve as baseline information on the economic losses associated with parasitic diseases of cattle at slaughter in Nigeria. © Indian Society for Parasitology 2019.
