Item 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.Item Serological investigation of bovine brucellosis in three cattle production systems in Yewa Division, South-Western Nigeria(2013) CADMUS, S.I.B.; ADESOKAN, H.K; stack, J; Alabi, P.I; Dale,E.JLimited data are available on the risk factors responsible for the occurrence of brucellosis amongst different cattle production systems in Nigeria despite its significant impact on livestock production. Consequently, a cross-sectional study was conducted to determine the prevalence of bovine brucellosis in three cattle production systems in Yewa Division of Ogun State, south-western Nigeria. A total of 279 blood samples (sedentary = 88; transhumance = 64; trade = 127) were examined for antibodies to Brucella sp. using the Rose Bengal test (RBT) and competitive enzyme-linked immunosorbent assay (cELISA). Overall, 24 (8.6%) and 16 (5.7%) of the animals tested seropositive for Brucella using RBT and cELISA, respectively. The herd seroprevalences based on RBT and cELISA were 31.6% and 15.8%, respectively. The results using cELISA reveal higher seroprevalence in the trade cattle (7.9%; confidence intervals [CI] = 3.2% – 12.6%) and those in a sedentary system (5.7%; CI = 0.9% – 10.5%) than in cattle kept under a transhumant management system (1.6%; CI = 1.5% – 4.7%). Age (> 3 years; p = 0.043) and breed (Djali; p = 0.038) were statistically significant for seropositivity to brucellosis based on cELISA, but sex (female, p = 0.234), production system (trade and sedentary; p = 0.208) or herd size (> 120; p = 0.359) was not. Since breeding stock is mostly sourced from trade and sedentary cattle, it is important that routine serological screening should be conducted before introducing any animal into an existing herd.Item Bovine fetal wastage in Southwestern Nigeria: a survey of some abattoirs.(2009) CADMUS, S.I.B.; ADESOKAN, H.KAs 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.Item Causes and implications of bovine organs/offal condemnations in some abattoirs in Western Nigeria.(2009) CADMUS, S.I.B.; ADESOKAN, H.KFood 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.
