Prevalence of intestinal helminth parasites of pigeons (Columba livia domestica Gmelin 1789) in Kano State, North-Western Nigeria

In Nigeria, helminths have over the last decades been established as important parasite of poultry including pigeons. However, the prevalence of these parasites of pigeons in Kano State is yet to be established. The prevalence of helminth parasites of domestic pigeon (Columba livia domestica) in Kano State, Nigeria was investigated in this study. The differences in the prevalence of infection between the pigeons examined on the basis of sex of the pigeon and season of the year were analyzed statistically using the students’ “t” –test. The intestinal contents of 144 pigeons were examined for gastrointestinal helminths between February and April representing the dry season and between June and August for the wet season. Pigeons were grouped according to Squabs (chicks) (0-4 weeks), Squeakers (Juveniles) (5-8 weeks) and Youngsters (Adults) (9 weeks onwards). Intestinal parasites found include Cestodes: Raillietina tetragona, 20 (13.80%), R. echinobothrida, 11 (7.64%), Amoebotaenia cuneata, 5 (3.47%), Hymenolopis contaniana, 10 (6.95%), Davainea proglottina, 1(0.69%) and Ornithostrongylus quadriatus 1(0.69%). Nematodes: Capillaria obsignata, 10(6.95%) and Ascaridia columbae, 9(6.25%). Forty-two (29.16%) of the birds had mild infection, 17 (11.81%) had moderate infection, 9 (6.25%) and 2(1.39%) had heavy and severe infection, respectively. The prevalence was higher during the wet season (36.65%) than during the dry season (27.97%). Of all the age groups, only Youngsters, 34 (23.61%) were infected with intestinal helminths. However, there were statistically significant differences between the age, sex and seasons in this study (P < 0.005). Pigeons raised on semi-intensive had the highest rate of infection (37.50%) and those raised on intensive management had the lowest rate of infection (9.03%). A number of measures are recommended for the control of these helminthic parasites.
