Mitonuclear incompatibility as a hidden driver behind the genome ancestry of African admixed cattle por Kwon, T., Kim, K., Caetano-Anolles, Kelsey, Sung, S., Cho, S., Jeong, C., Hanotte, Olivier H., Kim, H.

“…By contrast with B. indicus-enriched genome ancestry of African admixed cattle, local ancestries at these selection signatures were enriched with B. taurus alleles, concurring with the key expectation of selection induced by mitonuclear incompatibility.Our findings support the current genome status of African admixed cattle as a potential outcome of male-biased B. indicus introgression, where mitonuclear incompatibility exerted selection pressure against B. indicus mitochondria. This study provides a novel perspective on African cattle demography and supports the role of mitonuclear incompatibility in the hybridization of mammalian species.…”

Development and validation of a model for soil wetting geometry under moistube irrigation por Dirwai, T. L., Senzanje, A., Mabhaudhi, Tafadzwanashe

“…This implies the model’s applicability for estimating wetted distances for an MTI lateral placed at 0.2 m and MTI operating pressure of 150 kPa. We concluded that the models are prescriptive and should be used to estimate wetting geometries for conditions under which they were developed. …”

Antibiotic use by poultry farmers in Kiambu County, Kenya: exploring practices and drivers of potential overuse por Kariuki, J.W., Jacobs, J., Ngogang, M.P., Howland, Olivia

“…Antibiotic use was influenced by factors such as high disease burden, access to medicines and economic pressure. Common practices included prophylactic use, use of antibiotics to enhance production, self-prescription use, use of combination antibiotics (A combination antibiotic is one in which two or more antibiotics are added together for additional therapeutic effect.), and antibiotics classified as critically important in human medicine. …”

Watershed rehabilitation using rainwater harvesting and shrub establishment methods in Northern Afghanistan por Louhaichi, Mounir, Abdallah, Mohamed, Safi, Navin, Hassan, Sawsan, Gamoun, Mouldi, Ates, Serkan

“…Watershed rangelands in Northern Afghanistan provide various ecosystem services that support the livelihoods of local people, but they are now highly degraded essentially due to the continuous high grazing pressure and recurrent droughts. Effects of shrub establishment method enhanced by water harvesting techniques to rehabilitate degraded rangelands have not been well addressed. …”

Enclosures in West Pokot, Kenya: Transforming land, livestock and livelihoods in drylands por Nyberg, Gert, Knutsson, Per, Ostwald, Madelene, Öborn, Ingrid, Wredle, Ewa, Otieno, David Jakinda, Mureithi, Stephen, Mwangi, Peter, Said, Mohammed Y., Jirström, Magnus, Grönvall, Antonia, Wernersson, Julia E.V., Svanlund, Sara, Saxer, Laura, Geutjes, Lotje, Karmebäck, Vera, Wairore, John N., Wambui, Regina, Leeuw, Jan de, Malmer, Anders

“…Dryland livestock production systems are changing in many parts of the world, as a result of growing human populations and associated pressure on water and land. Based on a combination of social and natural science methods, we studied a 30-year transformation process from pastoralism to a livestock-based agro-pastoral system in northwestern Kenya, with the overall aim to increase the understanding of the ongoing transition towards intensified agro-pastoralist production systems in dryland East Africa. …”

Effect of Tithonia diversifolia (Hemsl.) A. Gray intake on in vivo methane (CH4) emission and milk production in dual-purpose cows in the Colombian Amazonian piedmont por Rivera, Julián Esteban, Villegas, Gonzalo, Chará, Julian, Durango, Sandra G., Romero Sánchez, Miguel Antonio, Verchot, Louis V.

“…We conclude that the inclusion of T. diversifolia in the forage feed base in the humid tropics such as the Amazon piedmont can be used as a tool to both mitigate enteric CH4 emissions and to increase animal productivity and hence reduce emissions intensity, and thus reduce pressure on the agricultural frontier in critical areas such as the Amazon.…”
