Thanks Olawale. My thoughts are that we shouldn’t think of any intervention as something that is universally needed – we should target it to systems where demand for the intervention exist, and also where other ‘success factors’ apply (e.g. favourable policy and institutional environment, or ability to create these). My feeling is that recording…[Read more]

Thanks Raphael for this update of the Dairy Genetics East Africa project, as well as your thoughts on how this could expand in the future. Their is often discussion on what is the minimum size of a reference population needed for genomic selection in African systems, such as smallhold systems (where their is often a lot of environmental noise…[Read more]

And on parentage testing – many people who have completed the survey indicated that they felt this was in demand from stakeholders. Are there examples of livestock parentage testing in African systems, and if so for what purpose …. or how do you see this being beneficial (or not).

Several people have mentioned using genomic approaches to determine breed composition of animals (where it cannot be assigned based on phenotype, or due to lack of recorded pedigree). Are their other examples of people using this in their research, or who would find this beneficial in relation to future research? And what about industry application?

Thanks for the update Baitsi. Do you see any demand for tracing of livestock products (where genomics could play a role) versus tracing animals (where ear-tags seem more cost-effective)?

Thanks for raising the excellent point on capacity. I will raise capacity building needs as a specific point in the forum next week.

Thanks – do you know of any countries actively working on traceability?

Yes, and those of us involved in Research for Development projects, are being increasingly asked to provide evidence on project outcomes (or, as you put it, real world impact)

On the question “Which genomic or genetic applications have the most potential to positively impact on the rural poor in Africa – in the near future and the longer term” we have had a number of responses in relation to genomic selection, including the varied constraints associated with implementation of such a scheme. But what about other g…[Read more]

Thanks Chanda. Africa also has the problem of scarcity of impact-oriented genomic studies, and it would be great to see more focus on this.

Yes I agree that increased productivity requires a ‘intervention package’ approach – jointly addressing genetics, feeding, and health-care amongst others. Also, that farmers need access to markets, a voice in value chain governance etc.
I would like to hear more from experts in genomic selection on their thoughts in relation to size of…[Read more]

HI – yes I agree that there has been a lot of confusion related to the term superior – many people think of this only in the terms of e.g. milk yield or growth rate, rather than also adaptability to harsh environmental conditions, disease resistance etc. Breeding animals is suit the needs of the production system / environment they are in, is very key.

Yes and the record keeping could also inform farm management decisions – which I think is a more immediate incentive than monitoring genetic progress.

Hi – Thanks for your comment. Please expand on what you would like debated – as this is a great forum for that.

Thanks. We have a project here (ILRI) looking at scaling of fixed-time AI. Also, we are testing a recording and feedback tool for AI service providers that is mobile-phone based (and aimed at increasing AI success rate, as well as improving service provision)

Yes in developed country dairy systems the use of genomic selection has reduced the cost of progeny testing. But do we have this evidence for African systems that are not analogous? I think more cost:benefit modelling studies would be useful to this end – particularly on the issue of what scale of operation is required.

Great to hear of these activities are the link or genetic improvement to dissemination programs.

Thanks for sharing the link to this cornerstone document. Advocacy on investment in African Livestock is indeed critical.

Great to hear about experiences from India!
Yes what you propose would be immensely beneficial. Can you say more on what India is doing towards building the required reference populations (with both genotyped and phenotyped animals) needed for this?

Hi all – looking forward to more contributions on current genomics / genetics work being performed on livestock systems in Africa, and what you think are the key applications of genomics / genetics that will impact positively on Africa’s rural poor. A summary of discussions to date on the first point can be found here.
