Importance of adaptation and genotype × environment interactions in tropical beef breeding systems.
This paper examines the relative importance of productive and adaptive traits in beef breeding systems based on Bos taurus and tropically adapted breeds across temperate and (sub)tropical environments. In the (sub)tropics, differences that exist between breeds in temperate environments are masked by the effects of environmental stressors. Hence in tropical environments, breeds are best categori...
متن کاملThe use of indigenous cattle in terminal cross-breeding to improve beef cattle production in Sub-Saharan Africa
The role indigenous livestock can play in Africa’s Livestock Revolution is not always recognized. In many parts of Africa pure breeding with indigenous breeds is the only viable production strategy because of adverse climatic and nutritional conditions. However, there are scenarios where the higher demands of exotic breeds and their cross-breds can be met. This article discusses the possibility...
متن کاملConservation of indigenous cattle genetic resources in Southern Africa’s smallholder areas: turning threats into opportunities — A review
The current review focuses on characterization and conservation efforts vital for the development of breeding programmes for indigenous beef cattle genetic resources in Southern Africa. Indigenous African cattle breeds were identified and characterized using information from refereed journals, conference papers and research reports. Results of this current review reviewed that smallholder beef ...
متن کاملUtilization of a 17 Microsatellites Set For Bovine Traceability in Czech Cattle Populations
For identification of individuals and parentage control performed by cattle breeders in the Czech Republic, a novel Finnish Bovine Genotypes™ Panel 3.1was amplified by means of one multiplex polymerase chain reaction. Bovine Panel encompasses all the 12 STR loci recommended by the International Society for Animal Genetics (ISAG) for routine use in parentage testing and identification, including...
متن کاملCollaboration and Co-Production of Knowledge in Healthcare: Opportunities and Challenges
Over time there has been a shift, at least in the rhetoric, from a pipeline conceptualisation of knowledge implementation, to one that recognises the potential of more collaboration, co-productive approaches to knowledge production and use. In this editorial, which is grounded in our research and collective experience, we highlight both the potential and challenge with collaboration and co-prod...
