The document presents a value chain analysis of products and by-products from egg-laying birds in peri-urban Nairobi, highlighting the need to understand input-output flows to identify disease risks. It details methods of data collection through focus group discussions and interviews, findings on commercial and indigenous bird profiles, and challenges faced in poultry production. The conclusion emphasizes the relevance of the value chain framework for public health and zoonotic disease management in urban settings.

2. Population of layer birds in Nairobi
There is a need for better understanding of flow
of inputs and outputs between these systems to
identify and target disease risks.

3. Objectives
The objective was to map profiles of value chains
for products and by-products from commercial layers
and indigenous birds within the City of Nairobi.

4. Materials and methods – Study areas

5. Materials and methods – Data collection
• Focus group discussions with poultry farmers: layers,
Indigenous birds.
– Inputs (day old chicks, mature birds, water, veterinary care,
feed);
– Outputs (products, buyers, farm gate prices).
– Challenges of poultry production, disease and food safety
risk.
• Key informant interviews with extension officers
– Triangulation of information

6. Materials and methods – Data analysis
• Mapping the chain for each system
– Interaction between value chain actors
– Flow of products and inputs.
– Qualitative description of risk practises
• Ranking challenges using non-parametric methods
(Kruskal Wallis One way Anova).

dead birds
System Peri-urban areas Informal settlements
Commercial
layers
• Seek advice from
veterinarians, hatcheries
• Isolation of sick birds
• Slaughter before bird dies
• Take the sick birds to agrovets
and seek advice on treatment
of those remaining in flock
• Dead birds are boiled and fed
to dogs
• Burying dead birds
• Given to garbage
collectors
• Home consumption
• Slaughter before birds
die
• Disposal in public
damping sites
Indigenous
layers

• Taken to “agrovets” for advice
on how to treat those
remaining in flocks
• Slaughter before sick

12. Conclusion
• Value chains framework which have been described
are useful for:
–Findings are important for assessment of zoonotic pathogen
and risk of their spread within the urban areas and in similar
settings
–Value chain framework provides some context in which public
health officers and veterinarians can formulate policies for
control of zoonoses.
–Limited value addition activities along poultry value chains
(layers and indigenous birds).
