A study was conducted to establish the prevalence of gastrointestinal (GI) and ecto-parasites of pigs in Gboko area of Benue state in Nigeria. Pigs are mainly reared using the intensive and semi-intensive methods but the latter predominates. It was hypothesized that the prevalence of parasites in the pigs would be high. Ecto-parasites were collected from their bodies and identified. Faecal samples were collected and examined for the presence of parasites, parasite eggs and coccidian oocysts. A total of 408 male and female pigs of varying ages were sampled. Of the pigs sampled, 251 were young (less than 5 months old) while 157 were old (from 5 months and above). The prevalence of GI nematodes was high as a total of 360 (88.2%) pigs in the locality were infected. However, the prevalence rate of GI nematode infections was higher in the young pigs because up to 235 (93.6%) of the 251 young pigs sampled were infected compared to 125 (79.6%) of the 157 old pigs sampled. The GI nematode infected pigs harboured one or more species of the parasites. The egg types identified were strongyles (86.5%), Strongyloides (19.4%), Ascaris (2.5%) and Trichuris (1.7%). Coccidian oocysts were common with a prevalence of 34.6% (141) of which 38.2% (96) were young pigs while 28.7% (45) were adult pigs. Two hundred and ninety four pigs were screened for ecto-parasites as not all pigs could be restrained. Lice infestation was very common with 231 pigs being infected giving a prevalence rate of 78.6%. Fourteen percent of the pigs harboured fleas. Twelve (4.1%) pigs harboured ticks (Amblyomma species). Alopecia and wounds on the backs and ears were also common Parasitoses were widespread in pigs in Gboko area of Benue state and hypothesized and needs rigorous control measures for productive pig industry in the area.
