Genome study will be used to breed more productive and resilient African cattle

Scientists have discovered a set of detailed genetic markers in African cattle that are associated with valuable traits such as heat and drought-tolerance, the capacity to control inflammation and tick infestations, and resistance to trypanosomiasis. The findings, published in Nature Genetics, emerged from a collaborative effort to sequence the genomes of 172 indigenous cattle by […]

Database of infectious cattle diseases in East Africa

A database of East African cattle health has been developed over three years by an international team of researchers led by the Roslin Institute. The Infectious Diseases of East African Livestock (IDEAL) database, developed from a study of more than 500 East African calves, gives users free access to extensive data on genetics and physical […]

Efforts to control PPRV should focus on herd management style, not age

A study in Tanzania explored the rate of Peste des petits ruminants virus (PPRV) infection across ages and livestock management styles of sheep and goats, as well as in cattle, which do not express symptoms but can be infected by the virus. The study, published in the journal Viruses, provides insight into how to target […]

African buffalo provide insights into the genetics of tuberculosis resistance

Morris Animal Foundation-funded researchers at Oregon State University discovered areas in the African buffalo (Syncerus caffer) genome linked to risk for tuberculosis (TB) infection. The researchers discovered areas of genetic code variation near genes associated with immunity to bacterial infections and demonstrated that these variations correlated with TB resistance. The team published their findings in […]

PPR risk associated with herd management system in Tanzania

A study published in Epidemiology and Infection provides an updated picture of the prevalence of Peste-des-petits-ruminants virus (PPRV) in northern Tanzania. According to the research team, livestock managed in a system where they are the sole source of an owners’ livelihood are more likely to become infected with PPRV than livestock managed in a system […]

Antimicrobial resistance at the wildlife-livestock-human interface in Nairobi

In a paper published in The Lancet Planetary Health, scientists from the University of Liverpool and the International Livestock Research Institute (ILRI) show that urban wildlife in Nairobi carry a high burden of clinically relevant antimicrobial resistant (AMR) bacteria, resistant to recently developed drugs that the World Health Organisation deems critically important to human medicine. […]

Cost of PPR vaccination in Ethiopia estimated

A study led by The Pirbright Institute has created the first framework for determining the true cost of peste des petits ruminants (PPR) vaccine campaigns based on case studies in Ethiopia. The new approach to cost estimation is important for the Global Control and Eradication Strategy launched by the Food and Agriculture Organization (FAO) and […]

Integration of livestock and wildlife may reduce the abundance of ticks in East Africa

A study, reported in the journal Nature Sustainability, has found that the integration of livestock and wildlife in a large region of central Kenya (Laikipia County) can have ecological benefits, reducing the abundance of ticks and improving forage. “Laikipia County hosts 10 percent of Kenya’s wildlife, but none of the country’s national parks or preserves,” […]

Project aims to boost productivity and health of village chickens

Adopting a more local and flexible approach to sustainable development could be key to improving the productivity of small-scale chicken farms in Ethiopia, according to a study published in Nature Sustainability. The research was led by the University of Liverpool, in collaboration with the University of Edinburgh, University of Nottingham, the Royal Veterinary College, Wageningen […]

Adaptation of Ugandan cattle to East Coast fever: landscape genomics analysis

Researchers have investigated the genetics of tolerance to theileriosis in indigenous cattle from Uganda. They first produced a map showing the areas of Uganda where the disease is most prevalent. The map is the result of a novel method compiling epidemiological data collected from 823 indigenous cattle along with their location. Using an environmental genomics […]
