Fasciolosis is a snail-borne disease of medical and economic importance which is distributed worldwide. In this study, we aim at determining the prevalence of fascioliasis in slaughtered goats in Bauchi North Senatorial Zone Abattoirs Bauchi State, Nigeria. Two hundred and seventy (270) faeces samples were collected randomly from slaughtered goats in the selected abattoirs for a period of three months (March -May, 2020). The samples collected were examined using formal ether concentration technique and the data were analyses statistically using chi-square and simple percentage. Out of the samples collected and examined, 120 were females and 150 males. The overall prevalence of 74(29.6%) was observed with the female species had the highest prevalence of 51(42.5%) and male with 23(15.3%). The prevalence rates between the different sexes of goat with fascioliasis in the area were statistically significant (𝑃 > 0.05). Open grazing of animals in swampy areas where snails are presence and watering of animal using streams, lack of regular de-worming are all influencing the prevalence rate of the parasite in study area. Public enlightenment to the farmers/rarer on the importance of regular de-worming and watering of their animals using clean water for their economic benefit and health conditions of their animals and consumers are recommended with the aim of maximizing the welfare of the farmer, improvement on profit of meat sellers as well as health condition of the consumers.

An epidemiological study was conducted from September-November, 2022 on the prevalence of gastrointestinal nematodes species among naturally infected ruminants slaughtered in Biu Local Area of Borno state, using centrifugal flotation techniques. Out of three hundred and eighty four (384) ruminants (162 goats, 110 sheep and 112 cattle) examined in the three selected abattoirs (Biu, Maringa and Buratai), 239 (62.34%) were infected. Maringa had the prevalence rate of 64.65%, Biu 63.89% and Buratai 63.16%. Although the highest faecal egg counts was recorded in Cattle 66.07%, the difference in prevalence rate between the different location and species of the animal were statistically insignificant p<0.05. The parasites identified were Ascaris lumbricoides 33.81%, Ancylostomidae spp 30.93%, Trichosrongylus spp 16.54%, Strongyloides stecoralis 11.27%, Haemonchus contortus 5.51%, and Entoribius vermicularis 1.91%. Fulani cattle breed had the prevalence rate of 20 (71.43%), Wad Sheep 45 (66.18%) and West African Dwarf goat 80 (65.57%). The difference in prevalence rate between the different breed of all the animals were not statistically significant p<0.05.The prevalence rate was 47 (72.31%) in male goats, 20 (41.67%) sheep and cattle 31 (67.39%) whereas female counterparts had 50 (51.55%), 48 (77.41%) and 43 (65.15%) in goat, sheep and cattle respectively. Both young and adults were infected with GI nematodes. Gastrointestinal nematodes are endemic in the study area. Therefore, mass administration of anthelmintic drugs, regular vaccination as well as educating the livestock’s farmers toward insuring production of healthy meat and improvement of their welfare is required to control the parasite in the study areas.
