General Context • Population increase
• 2012 -7 Billion • 2030 -9 Billion
• One billion people involved in
animal farming
• 70% rural poor depend on livestock for their livelihoods
• Domestic animals supply 30% of
total human requirements for food and agriculture
![Page 4: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/4.jpg)

How can the challenge be met?
– Increase in number of animals
• In developing countries- the
trend is increase in number
• But this has negative effect on
the already fragile ecosystem
– Improve productivity
![Page 6: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/6.jpg)
Opportunities
• Diverse and large number of genetic resources available –remains largely unexploited
• Available results – untapped potentials
– Productivity could be doubled
• Creative use of existing & emerging technology
![Page 7: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/7.jpg)
Challenges- general • Arrangements to correct past failures in livestock breeding
initiatives
– technology-driven productivity growth has largely failed
• Human, research and institutional capacity in developing
countries (E.g. States of the Worlds AnGR)
• Appropriate use of genotypes (local & exotic)
• Focus on “improvement”, not just breeding! “Empowering” not
“Restricting” the farmer
• Response to market demand (Example from Ethio.)
• Climate change –direct and indirect effect on AnGR -demand for
adapted genetics? (E.g. CBBP)
![Page 8: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/8.jpg)

Chicken!!
• Fulfilling different purposes in different times
• Forms of production systems
in LDC’s
• Large in number and wider in distribution
• Transformed to big industry
![Page 13: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/13.jpg)
Production systems in the tropics
• Village production system
• Commercial production system
• Small scale production system
Based on:
• Objectives of the producer
• Type and number of animals
• Management system followed
![Page 14: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/14.jpg)
Village production system
Predominant production system
• 40 to 90% of meat and egg
• Source of protein and small cash
• Continuous predominance of markets
Little attention to the system and animals
Even though local chicken are:
- good in a number of fitness treats
- Good mothers
- Requires low input etc
• 60 to 90% of chicken population
![Page 15: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/15.jpg)

![Page 20: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/20.jpg)
Transforming village poultry systems into small agro-business
ventures

Case number 1
![Page 21: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/21.jpg)
Background!
• Chicken research and development approach in the tropics
– exotic breeds of cockerels of 15-20 weeks of age in exchange for local cockerels of rural subsistence
– The other approach which is still being implemented is based on distribution of exotic breeds of chicken to individual farmers, a maximum of 6 chickens (5 pullets and 1 cockerel) per household.
– Although introduction of exotic breeds in the form of fertile eggs (Alemu and Tadelle 1997).
![Page 22: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/22.jpg)
Background cont..
• These schemes have been in effect since the beginning of poultry research and development in Ethiopia in the mid 1950s, and millions of improved breeds of chicken have since been distributed in the different forms (Alemu and Tadelle 1997).
• Despite such a large number of improved breeds introduced into the village system improvement was limited mainly due to the high mortality rate of modern breeds as a result of their poor adaptation to the rural environment.
• Distribution of 6 exotic chickens per household may still be considered useful in rural areas where opportunities for intervention at higher scales would be limited due to limited access to infrastructure and market.
![Page 23: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/23.jpg)
objectives
• To transform village poultry production into viable commercial venture in potential areas, and
• To generate sustained income for poor households,
![Page 24: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/24.jpg)
The implementation process
• Construction of poultry houses, hay box brooders and equipment
• Supervision, data recording, monitoring and evaluation
![Page 25: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/25.jpg)

layer strain • Feed: Formulated rations • Vaccination: Newcastle and Marek's disease • Drugs and chemicals: Antibiotics, vitamins and
disinfectants • Equipment: Waterers and feeders • Poultry house: Constructed of locally available
materials • Hay box brooder: Constructed of lumber and hay • Recommended management and health care practices
![Page 26: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/26.jpg)
Results Social assessment
• Attitudinal and institutional changes
– the awareness creation workshop and as time passes by and benefits realized, all parties got a conviction to consider the technology as a viable agricultural venture.
![Page 27: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/27.jpg)
Biological Assessment
• Egg production
– Birds attained egg laying at the age (5%) of 20 weeks
– Mean hen day egg production reached 41% after 20 weeks of laying.
![Page 28: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/28.jpg)

Mortality
• Survival of chicks during the first 8 weeks of brooding using this modified hay-box was almost 100% (99.5%).
• Only 3 chicks died in one household in Ada Wereda
![Page 30: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/30.jpg)
Mortality in the growing and laying
stages • On average about 96% of the chicken survived
to the laying age while mortality to from 19 to 40 weeks of age was less than 5%.
• The overall mortality of the flocks in the peri-urban village households was surprisingly less than 8%,
– a level even lower than the commercial standards ranging from 10-20.
![Page 31: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/31.jpg)

Socio-economic assessments
• The results from the economic trends implied by 20 weeks of egg production (about 40 weeks of bird's age) indicated that the operation is quite viable and has a very positive prospect of profiting
• Cost benefit analysis at farm household level
– net returns ranging from Birr 1939.00 to Birr 2806.00 were obtained with the total cost of production ranging from Birr 5788.00 to Birr 6311.00 in the periods considered.
![Page 33: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/33.jpg)
• The prospect from the rising trend of egg production coupled with the net benefit obtained so far (for the 20 weeks of egg production), clearly indicated the comparative position of poultry production to crop production. – For instance, comparing the average returns of Birr
2470.00 obtained from poultry production from only 18 m2 size of land to the profitability of crop production from 1 ha of land
• it was found that production of chickpea which was the most profitable crop in Ada-Liben gave returns to land, labor and management of 4505.00 Birr/ha followed by bread wheat (3999.00 Birr/ha) and tef (3827.00 Birr/ha)
![Page 34: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/34.jpg)
Manure!
• Considering the fact that poultry manure under such production system contains about 4 to 7 percent of nitrogen (Mitchell and Donald 1995),
– on average the economic value of the plant nutrients in poultry manure, produced from 100 birds, can be approximated as Birr 810.00 for the first 40 weeks of bird's age
![Page 35: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/35.jpg)
Challenges!
• Major challenges faced, potential threats to adoption of the model and issues for further consideration
– At the set out of this project there were persistent doubts and fear of risks both by the participant farmers and a few of the anticipated collaborators regarding the success of such a 'bold' initiative.
– As a result of such lingering doubts 3 farmers dropped out of the 18 farmers selected and trained to participate in the activity.

Poultry production in Ethiopia • Village system responsible for majority of poultry
production (more than 90% meat and egg)
Poultry offers poor people pathway out of poverty
(by and for the poor!!!!!! –real opportunity)
![Page 39: Village poultry production systems: challenges and opportunities …€¦ · · 2015-02-17Village poultry production systems: challenges and opportunities in achieving food security](https://reader034.fdocuments.in/reader034/viewer/2022051601/5ad84b277f8b9a991b8d1fa8/html5/thumbnails/39.jpg)
Vicious cycle of high poultry mortality and low productivity requires systemic change
High mortality
Limited care of flock
Reduced productivity
High mortality drives a vicious cycle
• High mortality and low productivity
reduces the incentive for farmers to
invest significant effort in caring for
birds
• Without basic care and vaccination,
mortality remains high, impacting
productivity.
• Basic practices such housing,
watering, egg removal are not applied,
further impacting productivity
Justification for change
• Low feasibility of vaccination in
backyard systems (low demand, plus
access challenges) means a health or
genetic intervention alone would be
unlikely to deliver sustainable benefit
• Establishing a breeding program creates
the infrastructure and scale (especially
for vaccinating chicks) as well as the
financial incentive for farmers to take
better care of their poultry
• Opportunity to break the vicious cycle,
improving both productivity and
survivability through a mix of moderate
breed improvement, and vaccination
• Requires establishment of a delivery
system that should become self-
sustaining in the long-term

Selection / development
Dissemination / multiplication
Supply to smallholders
• Research project identifying and testing different sources of indigenous chickens.
• Could involve within-breed selection or cross-breeding
• Might take 2 to 3 years (we have it).
• Establishment of multiplier flock.
• Starts with initial flock of female birds (and suitable number of cocks) selected or developed in Phase 1
• Rapid multiplication over period of 24-30 months to achieve scale
• Ongoing supply of chicks from the multiplier flock
• Some chicks retained as replacements to sustain multiplier flock
• Male and female chicks vaccinated and sold to farmers K

• Create initial flock:
– 100 hens
– Appropriate # of cocks
• Grow multiplier flock (hens)
– Start: 100
– 12 months: 1,970
– 18 months: 38,800
– 24 months: 765,000
– 30 months: 15 million
• Supply vaccinated chicks to farmers, while sustaining flock
– 10 male, 10 female per year
– Benefit: $???? per smallholder
– millions smallholders
– More million smallholders
Phase 1 Phase 2 Phase 3 2 years Ongoing
Scale can be achieved quickly through multiplier flocks in village-based mini-hatcheries

• Continue animal health investment to determine if lifelong disease resistance can be conferred by either a single vaccination to the chick, or through breeding (Newcastle, Marek’s disease)
• Opportunity to breed for disease resistance, or for synergy between breed and vaccine

As seen in the developed world, huge gains can be
unlocked through genetics
To fully benefit from breed improvement requires a system
approach (community/farmer) participation, health, nutrition
etc
This can also be a catalyst for improving the wider system
–triggering input supply, better marketing etc
Unlike many other types of intervention, benefits can span
generations
however…
but…
and…
Genetic improvement of livestock is complex, but
can deliver substantial and long-lasting benefits
