Indigenous goats make significant contributions to Cameroon’s national and local economy, but little effort has been devoted to identifying the populations. Here, we assessed the genetic diversity and demographic dynamics of Cameroon goat populations using mitochondrial DNA (two populations) and autosomal markers (four populations) generated with the Caprine 50K SNP chip. To infer genetic relationships at continental and global level, genotype data on six goat populations from Ethiopia and one population each from Egypt, Morocco,...

C. Arndt, A.N. Hristov, W.J. Price, S.C. McClelland, A.M. Pelaez, A.R. Bayat, L.A. Crompton, J. Dijkstra, M.A. Eugène, D. Enahoro, E. Kebreab, M. Kreuzer, M. McGee, C. Martin, C.J. Newbold, C.K. Reynolds, A. Schwarm, K.J. Shingfield, J.B. Veneman, D.R. Yáñez-Ruiz & Z. Yu
To meet the 1.5°C target, methane (CH4) from ruminants must be reduced by 11 to 30% of the 2010 level by 2030 and by 24 to 47% by 2050. A meta-analysis identified strategies to decrease product-based [PB; CH4 per unit meat or milk (CH4I)] and absolute (ABS) enteric CH4 emissions while maintaining or increasing animal productivity (AP; weight gain and milk yield). Next the potential of different adoption rates of one PB and/or ABS strategies...

Fidalis D. Mujibi, Edward Okoth, Evans K. Cheruiyot, Cynthia Onzere, Richard P. Bishop, Eric M. Fèvre, Lian Thomas, Charles Masembe, Graham Plastow & Max Rothschild
The genetic diversity of African pigs, whether domestic or wild has not been widely studied and there is very limited published information available. Available data suggests that African domestic pigs originate from different domestication centers as opposed to international commercial breeds. We evaluated two domestic pig populations in Western Kenya, in order to characterize the genetic diversity, breed composition and admixture of the pigs in an area known to be endemic for African swine fever...

Abdussamad, Margarethe Uerpmann, Hans-Peter Uerpmann, Bea De Cupere, Peter Magee, Majed A. Alnaqeeb, Bashir Salim, Abdul Raziq, Tadelle Dessie, Omer M. Abdelhadi, Mohammad H. Banabazi, Marzook Al-Eknah, Chris Walzer, Bernard Faye, Michael Hofreiter, Joris Peters, Olivier Hanotte & Pamela A. Burger
Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. We combined ancient DNA sequences of wild and early-domesticated dromedary samples from arid regions with nuclear microsatellite and...

The Technologies for African Agricultural Transformation (TAAT) is a program initiated by the African Development Bank (AfDB) as part of its Feed Africa Initiative. The main objective of the program is to improve the business of agriculture across Africa by raising agricultural productivity, mitigating risks and promoting diversification and processing in 18 agricultural value chains within eight Priority Intervention Areas (PIA). The program is implemented by IITA in close partnership with other CGIAR Centers and...

Data from: Modelling vaccination strategies against Rift Valley fever in livestock in Kenya: model code

John M. Gachohi, M. Kariuki Njenga, Phillip M. Kitala, Bernard K. Bett, Bernard Bett & Philip Kitala
The impacts of vaccination on the transmission of Rift Valley fever virus (RVFV) have not been evaluated. We have developed a RVFV transmission model comprising two hosts -- cattle as a separate host and sheep and goats as one combined host (herein after referred to as sheep) -- and two vectors -- Aedes species (spp) and Culex spp -- and used it to predict the impacts of: (1) reactive vaccination implemented at various levels of...

Data from: Understanding cryptic introgression and mixed ancestry of Red Junglefowl in India

Mukesh Thakur, Merwyn Fernandes, Sambandam Sathyakumar, Sujeet K. Singh, Ramesh Kumar Vijh, Jianlin Han, Dong-Dong Wu & Ya-Ping Zhang
Red Junglefowl (RJF), the wild progenitor of modern day chicken (DC), are believed to be in genetic endangerment due to introgression of domestic genes through opportunistic matings with domestic or feral chickens. Previous studies from India reported rare hybridization of RJF in wild, however, RJF population structure,pattern of gene flow and their admixture with DC populations are poorly understood at the landscape level. We conducted this study with the large sample size, covering the predicted...

Data from: Signatures of positive selection in African Butana and Kenana dairy zebu cattle

Hussain Bahbahani, Bashir Salim, Faisal Almathen, Fahad Al Enzi, Joram M. Mwacharo, Olivier Hanotte & Fahad Al Enezi
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst African indigenous zebu cattle because of their high milk production. Aiming to understand their genome structure, we genotyped 25 individuals from each breed using the Illumina BovineHD Genotyping BeadChip. Genetic structure analysis shows that both breeds have an admixed genome composed of an even proportion of indicine (0.75 ± 0.03 in Butana, 0.76 ± 0.006 in Kenana) and taurine...

Data from: Signatures of selection for environmental adaptation and zebu x taurine hybrid fitness in East African Shorthorn Zebu

Hussain Bahbahani, Abdulfatai Tijjani, Christopher Mukasa, David Wragg, Faisal Almathen, Oyekanmi Nash, Gerald N. Akpa, Mary Mbole-Kariuki, Sunir Malla, Mark Woolhouse, Tad Sonstegard, Curtis Van Tassell, Martin Blythe, Heather Huson & Olivier Hanotte
The East African Shorthorn Zebu (EASZ) cattle are ancient hybrid between Asian zebu × African taurine cattle preferred by local farmers due to their adaptability to the African environment. The genetic controls of these adaptabilities are not clearly understood yet. Here, we genotyped 92 EASZ samples from Kenya (KEASZ) with more than 770,000 SNPs and sequenced the genome of a pool of 10 KEASZ. We observe an even admixed autosomal zebu × taurine genomic structure...

Data from: Genetic diversity and population structure of Urochloa grass accessions from Tanzania using simple sequence repeat (SSR) markers

Salum O. Kuwi, Martina Kyalo, Collins K. Mutai, Angelo Mwilawa, Jean Hanson, Appolinaire Djikeng & Sita R. Ghimire
Urochloa (syn.—Brachiaria s.s.) is one of the most important tropical forages that transformed livestock industries in Australia and South America. Farmers in Africa are increasingly interested in growing Urochloa to support the burgeoning livestock business, but the lack of cultivars adapted to African environments has been a major challenge. Therefore, this study examines genetic diversity of Tanzanian Urochloa accessions to provide essential information for establishing a Urochloa breeding program in Africa. A total of 36...

Data from: Maasai pastoralists kill lions in retaliation for depredation of livestock by lions

Enoch M. Ontiri, Martin Odino, Antony Kasanga, Paula Kahumbu, Lance W. Robinson, Tom Currie & Dave J. Hodgson
The borders of national parks in Kenya are hotspots for human–wildlife conflict. The deliberate killing of lions by Maasai pastoralists is illegal, but continues despite mitigation attempts. Currently, there is a somewhat pervasive opinion, within the human–wildlife conflict literature, that lions are killed by Maasai people either as cultural ceremony or indiscriminately in response to the loss of livestock. We reconsider the indiscriminate reputation of lion‐killing, using a combination of structured dialogue and quantitative analysis....
