Actualization of strategies for beef quality control in south western Nigeria
(2005-06) Olugasa, B. O.; Cadmus, S.I. B.; Atsanda, N.N.
A major private abattoir wd meat processing plant in south-westem Nigeria was studied in this article to determine its compliance with control over dissemination of parasitic and microbial diseases from beef to man. To ensure total quality control, a private veterinarian sourced for cattle on farms and supplied these to the abattoir. In addition, a public health veterinarian in government service at the abattoir carried out antemortem tests, postmortem inspection and removal of unwholesome cattle. Diseases such as fascioliasis, tuberculosis, cysticercosis and brucellosis were effectively controlled in this way. Hence, United African Company (UAC) Foods provides wholesome beef to the community

African swine fever control in Ibadan, Nigeria: problems, needs and veterinary extension opportunities
(2008) Olugasa, B. O.
African swine fever (ASF) is a widely discussed disease in Ibadan, Nigeria, where high mortality losses occurred in outbreaks in the city between 2001-2006. To study the level to which ASF containment technologies were adopted and factors associated with adoption behavior, a sample of 60 pig farmers was selected from six local government areas in and near Ibadan. Essential data were collected using a questionnaire. Assessment criteria in forms of frequency, percentage, mean and product moment correlation coefficient were calculated. Results showed that the majority of pig farmers did not adopt ASF biocontainment technologies, since 86.7% (52/60) were at a low level of adoption behavior, 10% (6/60) at a medium level, and 3.3% (2/60) at a high level. A farmer’s income from piggery, knowledge of biocontainment technologies, and frequency of extension contact had positive and highly significant relationships (r 0.787) on levels of adoption. Specific needs and emerging opportunities for farmer participatory learning were indicated. It was recommended that Pig Farmers Association should constitute Farmer Field Schools, where the State Ministry of Agriculture and Natural Resources (MANR) would be involved in production of ASF virus-free pigs, and the current services by University-based officers to the early detection of pigs infected with the ASF virus will be optimized
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
Animal health management perspectives of rural livestock farmers in Southwest Nigeria: the place of community based animal health workers
(2010) Idowu, O. S.; Babalobi, O. O.
A case study of a typical community based rural livestock production system in South-west Nigeria was undertaken using participatory epizootiology (PE) to understand local preferences for animal health management practices and observe if there is any justification or place for community based animal health workers (CBAHW ) in rural livestock health and production management. Sheep and goats were the major animals kept by 46.7% of the respondents, followed by chicken (29.3%), dogs (13.3%), ducks (8.0%) and pigs (2.7%). The major health and production problems identified were Pestes des petit ruminants (PPR) (30.0% of respondents), mange (23.0%) and crop destruction (20.0%); while cannibalism by hawks/eagle was the major problem of poultry production as highlighted by rural women (15%). While more respondents (42.7%) rate modern animal health practitioners as more effective than Fulani pastoralists healers (33.67%) and indigenous local healers (25.0%), modern animal health practitioners were described as least truthful/ unreliable (91.7%), less available (91.7%), most expensive (66.7%) and inaccessible (25.0%). On the other hand, indigenous local healers were rated as very available and more accessible (66.7%) while Fulani pastoralist healers were rated as more available and ready to provide veterinary services (58.3%) compared to indigenous local healers (33.3%) and modern animal health practitioners (8.3%). These results are similar to those obtained in other African countries. In conclusion, despite the prevailing professional apathy to the CBAHW concept by influential veterinary authorities in Nigeria, health issues highlighted by the community-based rural livestock farmers could be adequately addressed by CBAHW.
Antibiotic Use and Resistance Development: Exploring Livestock Owners' Knowledge, Attitudes and Practices in south-western Nigeria.
(0020) ADESOKAN, H.K; ADETUNJI, V.O; AGADA, C.A; ISOLA, T.O.
Antibiotic injudicious use and resistance development remains a growing public health concern globally putting the livestock industry and human health at stake, given the resulting increasing emergence of resistant strains of pathogenic bacteria. Despite this, the role of livestock owners who manage the majority of the national herds in most developing countries especially Nigeria remains largely un-investigated. We conducted a qualitative study among 216 randomly selected livestock owners in south-western Nigeria to explore their knowledge, attitudes and practices on antibiotic use and resistance development using semistructured questionnaires. Data were analysed using SPSS version 15.0. The results revealed indiscriminate use of antibiotics by the livestock owners on ready-for-sale cattle. Only 49.54% had good knowledge which was significantly associated with tertiary education (p = 0.01) and 81.02% were unaware of antibiotic withdrawal period. Also, approximately two-thirds (63.89%) had poor attitudes with only 11.11% concerned with the need to observe withdrawal periods. In addition, 91.67% claimed that their veterinarians had never advised them to observe withdrawal period and 95.37% had never observed it. Poor professional attitudes of the so-called veterinarians as well as lack o f law enforcement against uncontrolled sales of veterinary drugs were attributed to the livestock owners' poor knowledge, attitudes and practices. The role of livestock owners should be considered when designing programmes towards preventing antibiotic injudicious use and resistance development. Furthermore, efforts geared towards regulating sales of veterinary drugs as well as enforcement of veterinary professional ethics are needed to safeguard antibiotic effectiveness in both animals and humans, now and in the near future.
Antibody levels against rabies among occupationally exposed individuals in a Nigerian University
(2010) Olugasa, B. O.; Odeniyi, A. O.; Adeogun, A. O.|; Adeola, O.A
The authors investigated the levels of antiglycoprotein antibodies against rabies virus in the sera of occupationally exposed humans at the University of Ibadan, Nigeria. A quantitative indirect enzyme‐linked immunosorbent assay (ELISA) was used to detect rabies virus anti‐glycoprotein antibodies in sera from 20 zoological garden workers, 20 veterinarians and 30 clinical veterinary students at the University of Ibadan. The sera were obtained between September 2008 and February 2009. Of these 70 healthy individuals, 29 (41.4%) consisting of 15 zoological garden workers (75.0%), 13 veterinarians (65.0%) and 1 veterinary student (3.3%) were immune to rabies virus (antibody titre >0.5 equivalent units per ml), while 41 (58.6%) were not immune. The prevalence of rabies anti‐glycoprotein antibody was higher within the older segment of the study population than among the younger veterinary students. Almost all those who had spent at least 10 years on the job had higher levels of rabies vaccination compliance and were immune. Our results indicated that there is low anti‐rabies immunity among occupationally exposed individuals at the University of Ibadan. There is a need for a complete course of primary and booster vaccinations of professionals exposed to the rabies virus. The impact of these results on rabies control in Nigeria is discussed.
Application of geographical information systems to assess the risk of trypanosomosis in Apete, Ibadan
(2001) Oguamanam, L.; Babalobi, O. O.; Fabiyi, O.
Geography information System (GIS) was applied to assess the risk of trypanosomosis at Apete area, Ibadan, Nigeria where the University of Ibadan’s Veterinary Teaching Hospital has a satellite station. Primary data were collected from physical field observations and interviews with residents and community leaders in the area between September 2000 and March 200.1 Secondary data sources included maps from Oyo State ministry of Land, Housing and Survey, International Livestock Research Institute ILRI. Internet Search and consultation with GIS personnel at the Geography Department of the University of Ibadan. Data analysis was done at DISEG Niq Ltd Ibadan. Software used included Arcview GIS Version 3.1® Atlas GIS® and Arc info GIS Microsoft Word 98® was used for typing Epizootological criteria chosen included the Forest Reserve Area Rivers and An-mal Host locations at Apete area. Results classified Apete area into high risk and medium risk areas and highlight the potential of GIS for landscape epizootological research. Recommendation are made for provision of relevant database of high quality which should be regularly updated. There is need for collaborative efforts with the GIS unit of Geography Department of the University.
The application of geographical information systems to veterinary medicine: an overview
(Faculty of Veterinary Medicine, University of Ibadan, Ibadan, 2002) Babalobi, O. O.; Fabiyi, O.; Oguamanam, L.
Geographical Information Systems, (GIS), are powerful computerized systems with inputting, storage, mapping, analysis and display of spatial data capabilities (spatial data are associated with a location on the earth’s surface). Geographical Information Systems have tremendously enhanced Ecological Epizootiology, the study of diseases in relation to their ecosystems. It has found increasing application for surveillance and monitoring studies, identification and location of environmental risk factors as well as disease prediction, disease policy planning, prevention and control. This article is an overview of the application of GIS to veterinary and medical research, education, decision support and information systems indifferent parts of the world, including Nigeria.
Assessment of seroconversion against peste des petits ruminants vaccine among sheep and goats in Buchanan, Liberia
(2012) Olugasa, B. O.; Anderson, J. R. N.
Serological response to a live commercial vaccine of Peste des petits ruminants (PPR) virus administered to sheep and goats in Buchanan, the capital city of Grand Bassa County, Liberia was assessed in view of its importance for effective restocking of small ruminants in the city. Forty-four paired serum samples (pre- and post-vaccination) were collected from vaccinated sheep and goats during a nation-wide campaign for food security promotion from March to October, 2011. Sheep and goats were vaccinated against PPR in late April, 2011. Pre-vaccination samples were collected in mid-April, 2011. Post-vaccination samples were collected in mid-October 2011 from the same groups of sheep and goats (6 months after vaccination). Paired serum samples gathered were stored at -4 0C until tested. Competitive Enzyme Linked Immunosorbent Assay (c-ELISA) was used to determine antibody levels against PPR virus. Only 34(77.3%) out of 44 paired serum samples were adequate in quantity and quality for the test. Test results indicated 27(79.4%) out of 44 paired serum samples increased significantly in antibody levels from pre-vaccination to post-vaccination levels that were equal or above threshold of Percentage Inhibition (PI > 50%) against PPR vaccine. The importance of these findings to effective veterinary services delivery for the control of this neglected animal disease in Liberia is discussed. The present seroconversion status against PPR virus is considered to be a milestone in rebuilding veterinary services systems in Liberia towards national efforts for food security after prolonged civil war (1989-2003) in the country.
Attitude of poultry farmers towards vaccination against newcastle disease and avian influenza in Ibadan, Nigeria
(2012) Oluwole, O..A.; Emikpe, B. O.; Olugasa, B. O.
Newcastle disease (ND) and Avian Influenza (AI) are among the important viral diseases of poultry with very high economic implications. ND is enzootic in most parts of the world while Highly Pathogenic AI (HPAI) is an emerging zoonosis in Nigeria. This study was carried out to assess the perception and attitude of poultry farmers in the selected Local Government Areas in Ibadan towards vaccination of birds against these diseases, and to find out the types of vaccines that were available for the control of the two diseases. A total of 84 respondents out of 100 (84%) completed and returned the questionnaires administered. The results indicated that all farmers vaccinated their birds against ND. The regime for ND vaccination was not the same across the local government areas. Some 32 (38.1%) farmers operated vaccination schedules provided by hatchery technicians, while 43 (51.2%) farmers vaccinated their birds at about 4-6 weeks interval. Nine (10.7%) farmers combined hatchery and laboratory evaluation to determine schedule. Thirty nine farmers (46.4%) indicated that they were aware of national policy of non-vaccination against AI. However, 14 out of 84 farmers (16.7%) vaccinated their birds against HPAI. There is a need to continue the national policy of slaughter of HPAI infected poultry birds and compensation of farmers, albeit allowing strategic use of vaccine to effectively control HPAI outbreaks in south-western part of Nigeria.
Bovine fetal wastage in Southwestern Nigeria: a survey of some abattoirs.
(2009) CADMUS, S.I.B.; ADESOKAN, H.K
As a result of inadequate veterinary services and indiscriminate slaughter of animals inmost Nigerian abattoirs, pregnant animals are often slaughtered resulting in wastage of scarce protein made available to the people. To this end, an evaluation of the volume of pregnant cows slaughtered at some abattoirs in Southwestern Nigeria between 2005 and 2007 based on meat inspection records was carried out with a view to determining the level of fetal wastage in this part of the country. A total of 321,448 cows were slaughtered, out of which, 16,092 (5.01%) were pregnant. The fetal wastages across the four seasons of the study period were statistically significant (P<0.05); the late dry season showing the highest percentage. There was a downward trend across the years, and this was considerably lower in 2007 than the other 2 years which were not statistically different from each other (XA2005=224.33; XA2006=216.38; XB2007=126.38). Our results indicated a considerable level of slaughtering of pregnant cows in the abattoirs studied. Hence, we advocate stepping up routine veterinary checks and interventions among trade animals in order to salvage the high level of fetal wastage in the region and the country at large.
Brucellosis In trade cattle in Lagos State: an investigation of two abbatoirs.
(2009) Cadmus, S.I.B; Osikoya,I.E; Adesokan,H.K
brucellosis affects domestic and wild animals as well as humans (charters,1980). Humans are usually affected due to zoonotic transmission from animals (mostly ruminants). Bovine brucellosis is usually caused by brucella abortus, less frequently by B. melitensis and rarely by B. suis (FAO,2003). it is usually manifested by abortion, with excretion of the organisms in uterine discharges and in milk. diagnosis depends on the isolation of brucella sp. from aborted material, udder secretion or from tissues removed at post-mortem examination. on the other hand, brucella antigens can be demonstrated through specific cell mediated or serological reactions(FAO,2003) the disease is endemic in Nigeria's livestock (Adamu and Ajogi,1999; Ishola and Ogundipe,2001) and serological prevalence rates of between 0.20% and 79.70% have been reported in various parts of the country 9Ocholi et al.,1977; Falade 2002; Cadmus et al;2006), therefore pointing at its public health implications. Lagos state is the second most populous state in Nigeria (NPC,2006) and the economic nerve centre of the nation. beef constitutes a major source of protein for the people in the state and equally a ready source of transmission of zoonotic diseases. since the last documented report of bovine brucellosis in Lagos state was about three decades ago(Esuruoso and ayanwale,1980), we therefore sought to determine the current status of the diseases among trade cattle in the state.
Causes and implications of bovine organs/offal condemnations in some abattoirs in Western Nigeria.
(2009) CADMUS, S.I.B.; ADESOKAN, H.K
Food animals though sources of protein and revenue to man, also serve as vehicles of disease transmission. This work reviews a three year record of slaughtered cattle in 12 abattoirs/slaughter slabs in western Nigeria to determine the economic and public health issues associated with their disease conditions. Out of 641,224 cattle slaughtered, 51,196 (7.98%) were attributable to 14 diseases/conditions including tuberculosis, pneumonia, fascioliasis, pimply gut, paramphistomosis, cysticercosis, dermatophilosis, tonsillitis, taeniasis, ascariosis, abscess, mange, mastitis and immature fetuses. Pneumonia (21.38%), fascioliasis (20.28%) and tuberculosis (7.95%) were major reasons for condemnations; least being ascariosis (0.01%). The lungs (45.66%) and liver (32.94%) accounted for most organ condemned while the heart (0.02%) was the least affected. The proportions of pneumonia, fascioliasis and immature fetuses observed were not statistically different (Mean = 3895.7; 3654.0; 3467.3); however, asignificant difference existed with other conditions (MeanA = 3895.7; 3654.0; 3467.3; MeanB = 1359.7; 1057.7; 510.3). Organs/offal condemnations constituted loss of revenue and animal protein as 124,333 kilo kilogrammes worth of meat valued in Naira at N41,613,043 ($332,904) was lost over the period giving an average of N13,871,014 ($110,968) annually. This, coupledwith fetal wastage represented an economic loss; with associated public health implications.

Community based participatory epizootiology of livestock kept by Awotan Women, Ido LGA, Oyo State, Nigeria
(2007) Ogunwale, I.; Babalobi, O. O.
Participatory Epizootiology (PE) is the use of participatory approaches and methods, involving the community based livestock keepers, to improve the understanding of their animal diseases and production problems, and to design appropriate veterinary intervention and other action plans for these problems Women are generally responsible for small stocks of livestock species kept in local communities This study was to investigate by the use of semi structured interviews, livestock diseases and health problems of traditional animal health projects in the study area, Awotan in Ido Local Government Area of Oyo State; with livestock keeping women as the primary respondents. The major species of animal kept were sheep and goats (51%), domestic fowl (27%), and dog (4%). They were kept under a semi intensive system of management in which the farmer have no adequate control over the animals. Common livestock diseases and health problems is encountered by female livestocks at Awotan were ranked by respondents as follows, Diarrhea (26%), Newcastle disease (22.7%), Mange (18%), Fowl pox 8.4%) petos des petite ruminants PPR (7.8%), Lice infestation 5.8%, Foot and nose bots 5.2%, Tick infestation 3.0%and Contagious Caprine Pleuro-pneumonia CCPP (1.95%). The farmers regard traditional intervention on the disease of their animals as very effective as a palliative treatment and modern veterinarian services as curative but less accessible and very expensive. Veterinary staff associated with the community complained about non conducive working environment and lack of mobility ambulatory vehicle, problems of ‘quacks’ that have motor cycles and go around disguising as veterinary doctors. Recommendations are made for the training of some educated community members as community animal health workers, the control of quackery in the Awoton, the provision of adequate mobility and conducive working environment for Veterinary staff, as well as provision of veterinary services to farmers at affordable prices.
A comparative assessment of the nutritional contents of ‘wara’ a West African soft cheese using calotropis procera and cymbopogon citratus as coagulants
(African Scholarly Science Communications Trust, 2011) Adetunji, V. O.; Babalobi, O. O.
The processing line of West African soft cheese varieties (processed with Calotropis procera (Sodom apple) and Cymbopogon citratus (lemon grass) leaf extracts was assessed for nutrient compositions (nitrogen, crude protein, fat, lactose, moisture content), pH, total aerobic plate count and trace elements (Fe, Zn, Cu, Mn, Na, Ca, Mg and K). The percentage of nutrient composition, pH and the total aerobic plate count of microbes were: milk (nitrogen (2.05), protein (2.78), fat (5.33), lactose (1.86), moisture contents (88.75), pH (3.91) and total aerobic plate count (7.3logcfu/ml); Calotropis procera processed cheese (nitrogen (2.00), protein (2.56), fat (4.43), lactose (1.72), moisture contents (62.89), pH (3.58) and total aerobic plate count (7.34logcfu/ml); Cymbopogon citratus processed cheese (nitrogen (2.01), protein (2.53), fat (4.33), lactose (1.68), moisture contents (63.56), pH ( 3.56) and total aerobic plate count (7.43 logcfu/ml). There were significant differences between the parameters measured in the raw milk and processed cheese at 95% confidence limit. However, the parameters measured varied slightly in the two cheese varieties (Calotropis procera and Cymbopogon citratus). The total aerobic plate counts in milk and cheese were higher than international standards set by Codex alimentarius. Addition of leave extracts (Calotropis procera and Cymbopogon citratus) increased the total aerobic plate counts but the counts dropped at the curdling point during processing. Cymbopogon citratus cheese had a higher total aerobic plate count than the Calotropis procera cheese although not at a significant level. There was an increase in Fe, Zn, Cu and Na along the processing line, but a decrease ensued in Mn, Ca, Mg and K. There was no significant difference in the Zn, Cu, Mn, Ca, Mg, K, N, protein, fat and lactose contents of the two cheese types although all trace elements and nutrients assayed were higher in the Calotropis procera processed cheese with the exception of Fe content. The study suggests the use of Cymbopogon citratus leaf extract as a local milk coagulant due to reports of probable health hazard from the use of C. procera. However, further work on improving the yield of cheese when Cymbopogon citratus is used as coagulant is still necessary.
Comparative evaluation of productivity and cost effectiveness of catfish fingerling production in earthen pond and recirculation system in Ibadan, Nigeria
(2011) Adeyemo, O. K.; Ganiyu, O. I.; Olugasa, B. O.
Despite the popularity of the African catfish and its great market potentials, the production is still basically at subsistence level due majorly to inadequate supply of seed for stocking. This has been linked to the absence of reliable production techniques for the mass production and rearing of the species under practical farming conditions. The purpose of this study therefore, was to find a suitable culture system for the mass production of catfish (Clarias gariepinus) fingerlings. Protected earthen pond and a unit of recirculation system were used. Fertilized eggs from female were divided into two equal halves and incubated under the same conditions. Forty-nine thousand frys each were stocked into the protected earthen pond and a unit recirculation system respectively. The frys in the two systems were raised for twenty one days and fed the same quantity and quality of feed throughout the period. The survival rate of the frys in the recirculation system was 79% as against 17% in the earthen pond. However, bigger sized (2.2 ± 0.23g) fingerlings were obtained from the earthen pond relative to those cultured in the recirculation system (0.9 ± 0.07g). The cost of raising frys in a recirculation system (N34,000) was twice that needed for earthen pond (N17,000), but this was more than made up for in the profit from sales, which was N311,360 and N99,156 respectively. The main reason for fish farming is the expected return to be, therefore, the choice of income-generating activities, amongst several options available, should be made on the grounds of their expected returns.
