    Analysis and evaluation of mortality losses of the 2001 African swine fever outbreak, Ibadan, Nigeria
    (2007-08) Babalobi, O. O; Olugasa, B. O.; Oluwayelu, D.O.; Ijagbone, I. F.; Ayoade, G. O.; Agbede, S. A.
    The mortality losses of pigs of various age groups affected by the 2001 African swine fever outbreak in Ibadan Nigeria were analyzed and evaluated. Thirty one thousand nine hundred and sixteen (31,916) pigs on three hundred and six (306) farms reported by the Pig Farmers Association of Nigeria and the State Ministry of Agriculture and Natural Resources were involved. Gross mortality was ninety one percent (91%), while age group mortality ranged from 75.9% (growers), 83.1% (weaners), 91.2% (finishers) and 99.8% (piglets); to 100.0% in gilts, sow and boars. Losses were estimated to worth nine hundred and forty one thousand, four hundred and ninety one dollars, sixty seven cents (US $941,491.67). Highest financial loss was from sows (29.5% of total loss), followed by gilts (16.6%), finishers (15.2%), weaners (10.7%), boars (10.6%), growers (10.6%) and piglets (8.2%). Average mortality loss per farm of $3076.77 was of great financial and socioeconomic consequences for a developing country like Nigeria with a low Gross Domestic Product figures. In conclusion, the need to immediately revisit and take recommended actions on the 1998 Report of the FAO Consultancy Mission to Nigeria on Control and Eradication of an Outbreak of African swine fever in Western Nigeria is stressed

    Ano-rectal malformations in pigs: a report of a striking case in an eight-week-old piglet (a case report)
    (2011) Eyarefe, O. D.; Abiola, J. O.; Oguntoye, C. O.; Ayoade, G. O.
    Anorectal malformations are rare congenital disorders in animals. In swine, atresia ani occurs with an incidence of 0.1—1.0 % and it is the most important cause of intestinal obstruction in that species. This paper reports a striking case of atresia ani et recti in an eightweek- old piglet. The surgical management and preventive measures are discussed

    Differential diagnosis of a swine epizootic of unknown etiology in Ibadan, Oyo State, Nigeria
    (2003) Babalobi, O. O.; Ayoade, G. O.; Olugasa, B. O.; Oluwayelu, D. O.; Oyedele, O.
    Outbreaks of unconfirmed infections associated with high mortalities in pig herds were reported at the University of Ibadan Teaching and Research Farm, and in other parts of Ibadan, Nigeria between June and October 2001. Based on a tentative diagnosis of African Swine Fever and differential diagnosis of classical swine lever, encephalomyocarditis virus and anthrax, research was initiated between July and November 2001 to confirm the cause of the outbreak. This included farm visit, to observe clinical signs, collect samples and do necropsies, electronic mail communication of presenting signs. Internet web searches. laboratory tests and serological (immunoblotting assay) tests A confirmatory diagnosis of the infection as African Swine Fever (ASF) was reached. This diagnosis is important to enable researchers and appropriate authorities to introduce monitoring and control measures.

    Intenstinal helminth and protozoan parasites of pigs reared under intensive management system in Ibadan, Nigeria
    (Tropical Veterinarian, 2001) Adejinmi, J. O.; Adedokun, O.A; Ayoade, G. O.; Obadua, A. A.
    Two hundred and seventy two pigs of different age groups reared in an intensive management system in 10 different locations in Ibadan were screened for intestinal helminth and protozoan parasites. The following incidences were recorded. Ascaris suum, 25.4% Oesophagostomuir. dentatus 13.6%, TricJiiiris suis, 10.7%; Strongylodes ransomi, 7.0%; Eimeria debliecki, 31.3%, Eimeria suis, 2.2% and Balantidium coli. 0.74%. Mixed infections with these parasites were common. No helminth egg was detected in all the piglets screened. The incidence of helminth parasites increased with age. So also was the worm burden. To prevent widespread infection with these parasites strict adherence to good management and hygiene in piggery pens is recommended
