“…The overall seroprevalence of 14.5% reported for FMD in this study is indicative of its importance in feedlots business. The individual animal seroprevalence result obtained in this study was in close agreement with the previous findings from Andassa dairy farm (Mazengia et al, 2010) and Jijiga zone (Mohamoud et al, 2011) in which seropositivity of 14.6 and 14.05% were reported, respectively. On the other hand, the prevalence reported in this study is a higher value than previous reports of 8.18% (Molla et al, 2010) and 9.5% (Megersa et al, 2009) in South Ethiopia.…”

The study was conducted in central part of Ethiopia in 2011 with the objectives to determine seroprevalence and associated economic impact on cattle feedlots. From the total of 38,187 bulls examined for foot and mouth disease (FMD) antibody, 5,536 (14.5%) was found positive and subsequently rejected from international market. The seropositivity of FMD varied from site to site and the variations were statistically significant (χ 2 = 3.28, df = 9, p < 0.001). Similarly, there was statistically significant (χ 2 = 4.55, df = 9, p < 0.001) difference between months of the year. The total annual (2011) economic loss due to bulls rejection from international market was estimated to be 3,322,269 USD which is equivalent to 56,345,682.24 ETB (1 USD = 16.96 ETB). This study indicates that FMD resulted in bulls' rejection from international market which affect livelihood of actors in the value chain and have a major threat to national economies as they tend to affect the international trade. Therefore, directing surveillance and controlling activities at pastoral production system where FMD risk arise and appropriate intervention measures along the market chain are critical factors necessary to prevent the introduction and spread into feedlots.

“…Presence of wildlife population along the national park in Borgu Niger State Nigeria where cloven hoofed species come in contact with live stock was shown to be the probable exposure factor that contributed to high FMD sero-positivity in livestock observed in the area (37). The results from this study corroborate with other studies in South Africa, Zimbabwe, Zambia, Botswana, Namibia, India, Chad and Iran that demonstrated FMDV antibodies in wildlife (40, 10, 41, 42, 43, 28, 11, 44, 45). High FMDV prevalence in waterbuck observed in this study reflects their ecology and living ecosystem which is consistent with other findings in East Africa and Zimbabwe (41, 27, 46).…”

“…The current trend of FMD occurrence in Nigeria showed that there are regular outbreaks, poor control measures and lack of enforcement of legislation guiding disease reporting to veterinary authority (24, 25). The presence of antibodies to FMDV in several wildlife species have been documented in studies conducted in different countries of Africa mainly eastern and southern regions (26, 27, 28). There has been limited monitoring of infectious diseases like FMD in wildlife in Nigeria.…”

18Background 19 Foot and mouth disease (FMD) is one of the most economically important transboundary 20 animal diseases with devastating consequence on livestock production and wildlife 21 conservation. The objectives of the study were: to determine the seroprevalence of FMDV in 22 wildlife and cattle and identify circulating FMDV serotypes in wildlife and identify potential 23 risk factors that will contribute to transmission of the disease at the wildlife-livestock 24 interface in Yankari Game Reserve and Sumu Wildlife Park in Bauchi State, Nigeria. 25 Methods 26Blood samples were collected between 2013 to 2015 from some wildlife and cattle 27 respectively within and around Yankari Game Reserve (YGR) and Sumu Wildlife Park 28 (SWP) in Bauchi State, Nigeria. The Wild animals were immobilized for blood collection 29 using a combination of Etorphine Hydrochloride (M99® Krüger-Med South Africa ) at 0.5-2 30 mg/kg and Azaperone (Stresnil®, Janssen Pharmaceuticals (Pty.) Ltd., South Africa) at 0.1 31 mg/kg using a Dan-Inject® rifle (Dan-Inject APS, Sellerup Skovvej, Denmark) fitted with 3 32 ml dart syringe and for reversal, Naltrexone (Trexonil® Kruger-Med South Africa) at 1.5 mg 33 IM was used, cattle were restrained by the owners for blood collection. Harvested Sera from 34 blood were screened for presence of Antibodies against FMDV using prioCHECK® 3 ABC 35 NSP ELISA kit and positive samples from wildlife were serotyped using Solid-Phase 36Competitive ELISA, (IZSLER Brescia-Italy). Data obtained were analysed using Graphpad 37 Prism version 7. 38 Results 39The results showed that 197 (65.7%) of the 300 serum samples from cattle and 13 (24.5%) of 40 the 53 serum samples from wildlife tested positive for antibodies to the highly conserved 2 41 non-structural 3-ABC protein of FMDV and statistically significant (P <0.05). Classification 42 of cattle into breed and sex showed that detectable antibodies to FMDV were higher (P 43 <0.05) in White Fulani 157 (72.8%) than red Bororo 23 (39.7%) and Sokoto Gudali 17 44 (33.3%) breeds of cattle whereas in females detectable FMDV antibodies were higher (P 45 <0.05) 150 (72.8%) than in males 47 (50.0%). In the wildlife species, antibodies to FMDV 46 were detected in waterbuck 2 (28.6%), elephant 1 (25.0%), wildebeest 4 (33.3%) and eland 6 47 (25.0%). Four serotypes of FMDV: O, A, SAT-1 and SAT-2 were detected from the 3-ABC 48 positive reactors in waterbuck, elephant, wildebeest and eland. Contact of wildlife and cattle 49 during utilization of the rich resources in the conservation areas is a potential risk factor for 50 the spread of FMDV in the study area. 51 Conclusions 52 Presence of FMDV antibodies in cattle and some wildlife were observed and serotypes of 53 FMDV: O, A, SAT-1 and SAT-2 were detected from the 3-ABC positive reactors in some of 54 the wildlife. The study highlights the need for active surveillance of FMDV in wildlife and 55 pastoral cattle within and around wildlife conservation areas in Nigeria. FMD surveillance 56 system, control and prevention progra...

“…A study conducted at Andassa Government Dairy Farm (Ethiopia) indicated that the incidence of FMD in dairy cattle was found to be 14.5% and the average milk production for cows that contracted FMD was low. The average milk yield ahead of 10 days of FMD infection was found to be 1.183 kg while 10 days after infection was 0.603 kg, the difference of which was found to be statistically significant (Mazengia et al 2010). In relation to this, the discussion of key informants indicated that problems related to access to veterinary service, medication supply, and cost of medication aggravated milk productivity in particular and dairy farm production in general.…”

Empirical studies on smallholder dairy farmers' risk perceptions and management strategies have still received little attention in agricultural research of developing countries. This study focuses on farmers' risk perception and management strategies of smallholder dairy farms in urban and peri-urban areas of Tigray in northern Ethiopia. Based on data collected from a sample of 304 smallholder dairy farm households, we used descriptive statistics for analyzing farmers' risk attitude and factor analysis for analyzing and classifying risk sources and management strategies. The majority of dairy farmers considered themselves risk takers towards farm decision that may have a positive impact on technology adoption. Factor analysis identified technological, price/market, production, financial, human, and institutional factor as major sources of risks. In addition, factor analysis indicates that disease reduction, diversification, financial management, and market network are perceived as the most effective risk management strategies. Our findings indicate that perceptions of risk and management strategies are farmer-specific; therefore, policy-makers need to consider tailor-made strategies that would address farmers' individual motives to manage risks and shocks.
