    Ectoparasites and haemoparasites of indigenous chicken (gallus domesticus) in Ibadan and environs.
    (Tropical Veterinarian, 2003) Sadiq, N.A.; Adejinmi, J.O; Adedokun, O.A.; Fashanu, S.O.; Alimi, A. A.
    This research undertook the study of ectoparasites and haemoparasites found on and in the body of indigenous chicken (Gallus domesticus). Six hundred and nineteen ectoparasites were collected from 375 chicken from 28 households in and around Ibadan city between February and November, 1999. Of these, 455 (72.72%) were lice, among which 253 (40.12%) were Menopon ga/linae, 53 (8.4%) were Columbicola columbae, 48 (7.75%) were Goniocotes hologuster, 33 (5.33%) were Goniodes gigas, 31 (5%) were Chelopistes meleagridis, 23 (3.7%) were Liperus capon is and 15 (2.42%) were Cuclotogaster heterographus. One hundred and twenty one (19.55%) were identified as the soft tick Argas persicus. Fourty three (6.94%) mites, identified as Dermanyssus gallinae were also found. Giemsa stained smears from 150 uncoagulated chicken blood samples examined at x 1,000 magnification, revealed presence of Plasmodium species (spp.) in 48 (32%) of the samples. Leucocytozoon spp accounted for 30 (20%), while Haemoproteus spp was identified in two (1.3%) of the samples. Mixed infection with Plasmodium spp and Leucocytozoon spp w'ere identified in 14 (9.33%), while Leucocytozoon spp and Plaemoproteus spp were identified in four (2.67%) of the blood samples. Six (4%) of the blood samples have the three haemoparasites. The need to control these ectoparasites was stressed

    Newcastle disease, infectious bursal disease and EDS ’76 antibodies in indigenous Nigerian Local Chickens
    (Tropical Veterinarian, 1999) Adedokun, O.A.; Durojaiye, O.A
    A serological survey was conducted to determine the prevalence of Newcastle disease (ND), infectious bursal disease (IBD) and egg drop syndrome ’76 (EDS ’76) antibodies in indigenous Nigerian local chickens. The survey was carried out in Ekiti, Osun, Oyo, Ogun and Lagos States in southwestern Nigeria. Out of 2010 serum samples assayed for ND, 1890 (94%) were positive. 720 (34%) out of 2090 samples were positive for IBD, while 500 (29%) out of 1740 samples were positive for EDS ’76. The prevalent rates are high enough to suggest that ND, IBD and EDS ’76 are still very active in these indigenous chickens. The implications of these findings in the control of ND, IBD and EDS ’76 in the commercial exotic poultry flocks are discussed.

    Lice lipeurus caponis infestation in turkey and chicken in Ibadan, Nigeria
    (2005-12) Sonibare, A.O.|; Ayoade, G.O.; Adedokun, O.A.; Kumshe, H.A.; Olufemi, E.B.; Otesile, E.B.
    Louse infestation in chickens and turkeys in Ibadan is reported. The birds including guinea fowl were housed together fed on corn, guinea corn shaft and household left overs and left to roam together in an enclosed area in a semi intensive system type of management. Report was made on a sudden drop in egg production in the birds, which finally stopped in the chickens and turkeys. Clinical examination revealed massive lice infestation in the turkeys and chickens but the guinea fowls had no louse. Examination of blood samples from 47% of the birds revealed no haemoparasites and haomatological parameters were within normal range. The lice was identified to be Lipeurus caponis
