Abstract Livestock abortion is a source of economic loss for farmers, but its impact has not been estimated in many Low and Middle-Income Countries. This article presents an estimation methodology estimates the gross net cost based on sample livestock-owning households three regions northern Tanzania market data. We then generate aggregate losses across Tanzania. estimate annual about $263 Million (about TZS 600 billion) $131 million 300 billion), respectively.

Livestock keepers in sub-Saharan Africa face a range of pressures, including climate change, land loss, restrictive policies, and population increase. Widespread adaptation response can lead to the emergence new, non-traditional typologies livestock production. We sought characterise production systems two administrative regions northern Tanzania, an area undergoing rapid social, economic, environmental change. Questionnaire spatial data were collected from 404 livestock-keeping households...

Abstract Livestock abortion is an important cause of productivity losses worldwide and many infectious causes are zoonotic pathogens that impact on human health. Little known about the relative importance livestock in Africa, including subsistence farming communities critically dependent for food, income, wellbeing. We conducted a prospective cohort study abortion, supported by cross-sectional serosurveillance, to determine aetiologies abortions Tanzania. This approach generated several...

Abstract Background Human and animal cases of Rift Valley fever (RVF) are typically only reported during large outbreaks. The occurrence RVF that go undetected by national surveillance systems in the period between these outbreaks is considered likely. last Tanzania occurred a outbreak 2007–2008. Methods Samples collected 2017 2019 from livestock suffering abortion across northern were retrospectively tested for evidence virus infection using serology reverse transcription quantitative...

Neospora caninum is a protozoan intracellular parasite of animals with global distribution. Dogs act as definitive hosts, infection in cattle leading to reproductive losses. Neosporosis can be major source income loss for livestock keepers, but its impacts sub-Saharan Africa are mostly unknown. This study aimed estimate the seroprevalence and identify risk factors N. northern Tanzania, link herd-level exposure Serum samples from 3,015 were collected 380 households 20 villages between...

Rift Valley fever virus (RVFV) is a mosquito-borne pathogen that has caused epidemics involving people and animals across Africa the Arabian Peninsula. A number of studies have found evidence for circulation RVFV among livestock between these but population-level incidence infection during this inter-epidemic period (IEP) rarely reported. General force (FOI) models were applied to age-adjusted cross-sectional serological data reconstruct annual FOI cattle, goats, sheep in northern Tanzania...

Abstract A neurological syndrome of small ruminants, known locally as ‘ ormilo ’, has been reported among pastoralist livestock keepers in Tanzania. This study was carried out four affected pastoral communities to determine the prevalence and associated risk factors, characterise clinical signs investigate aetiology syndrome. Questionnaires were administered at all households (n=480) within villages. Overall, 94 per cent least one case previous 12 months. By village, individual‐level...

Fasciolosis is recognised as a major problem in dairy cattle Cajamarca, Peru. The infection has an annual cycle, with the period of from January to March. A control programme, involving two doses fasciolicide triclabendazole aimed at reducing passage Fasciola hepatica eggs on pasture, together use molluscicide, niclosamide, was evaluated against traditional treatment programmes. double regimen did not significantly reduce overall parasite burden, measured by faecal egg counts, but parasites...
