Livestock Genetics program is a valued and globally
recognized partner which provides:
• state-of the-art breeding technology and data platforms
• leadership in the areas of gene discovery, genetic diversity
characterization utilization of the results in integrating these
in the R&D contexts to continuously improve, deliver and
promote use of more productive and healthy livestock under
tropical systems
The desired program outcome:
Appropriate livestock breeds are readily available, affordable
and widely used by poor women and men livestock keepers,
resulting in increased livestock productivity, improved food and
nutritional security, better livelihoods and improved natural
resource that support them.
3. Objectives
• To determine the most appropriate genetic
improvement strategy for different systems
• Discover genes responsible for productivity &
resilience and develop/adapt technologies to efficiently
incorporate them in breeding programs
• Design and support implementation of sound breeding
programs & delivery of the desired genetics to a range
of livestock keepers
• Identify policy gaps & provide evidence for and need
for policies and institutional arrangements that would
enable improved access, sustainable use of livestock
genetic resources.
4. Why genetics: Need to close the livestock productivity
gap

Figure 1: Realized lactation curves of improved (crossbred or higher) dairy cows achieved by
different farmer types in Kenya
Commercial/Intensive dairy farmers –
~6,500 kg/lactation --- ~2% of farmers
Best smallholder farmers - ~2,500
kg/lactation --- ~5% of farmers
Average smallholder farmers --- ~1,400
kg/lactation --- >90% of farmers
• Mitigate risks (e.g. effects of CC,
emerging diseases (zoonotics))
• Work towards ensuring equity (focus
on chicken, and small ruminants and
crossbred dairy cattle & buffalos to
widen our reach)
• Ensure environmental health (e.g.
increasing productivity/animal to
reduce GHG emissions)

6. Program Strategy
Short term:
• Apply existing ICT & Genomic technologies to better understand the existing genetic diversity
• Roll out systems for on-farm testing and models for delivery of promising existing genetics
Medium term:
• Identification of genes / gene-networks underpinning important traits and incorporate these in the
breeding programs
Long term: Integrate breeding and molecular technologies to design and deliver optimized genetcs
programs
7. What do we work on:
Sheep
Dairy cattle
Pigs
Dual purpose
cattle
Poultry Goats
8. Where we work
Future livestock demand scenarios indicate that most of the supply of livestock products is likely to come from
smallholder and agro/pastoral production systems for the foreseeable future in Africa (Herrero et al., 2014) and Asia
(Hemme et al., 2015). Therefore, the Livestock Genetics Program will target the smallholder sector for achieving
sustainable impact at scale.

20. Cross program linkages- Greater impact through
partnerships within and outside ILRI
Significant interaction between other
programs at value chain levels:
Focus on joint project design, technology
development/testing and delivery, influencing:
Sustainable Livestock production systems-Livestock
AVCD
Policy, Gender –Dairy- AVCD,ADGG.ACGG
Forage and Feed Resources- gene discovery/
genomics for improvement, Genetic Gain
Human and Animal Health- pathogen/host resistance,
Microbiome research (chicken & dairy)
Impact at scale-AVCD, ADGG/links with development
partners
Tool & Data systems support- RMG, Big data.
Significant yield gaps are seen on-farm. While dramatic increases in yields have historically been driven by highly
accelerated genetic gains, the full potential is not realized without the delivery of appropriate technologies,
improve feed, disease management, and delivery.

23. Time for a new search for variation underlying tropical adaptation and
productivity
Identify and make use of the genetics
underlying natural variation.
There has been no systematic search for
the genomic basis of adaptation. Because
until now we have had no validation
tools and no delivery tools.
New Genome Editing tools change the
landscape.

Senegal Dairy Genetics
What is the most appropriate cattle breed-type
for the production system & environment?
Via trade-off analysis – productivity, livelihood
benefit, environmental sustainability, food safety
3500 animals from 220 households monitored for almost
2 years- production, economic, gender data
Different breeds / cross-breeds & management levels
Breed-types assigned based on genomic data -
~30% match between farmer assigned breed-type & that
from the genomic data
