7 billion and counting
More and more people to feed
More and more are not producing food
The rest need to produce more
Over 50% urban
Production has to move close to urban areas
![Page 4: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/4.jpg)
The livestock revolution
• 1970-Mid 1990s
• Demand-driven, in difference to green revolution
![Page 5: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/5.jpg)
Not only demands Food security and sustainability
Bridging the gaps between demand and supply – global level
•FAO projections to 2030, demand for meat will increase by 3.7% and milk 2.7%
•60% more food than is produced now will be needed
•75% of this must come from producing more food from the same amount of land
•The higher production must be achieved while reducing poverty and addressing environmental, social and health concerns
•This greater production will have to be achieved with temperatures that may be 2−4 degrees warmer than today’s
![Page 6: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/6.jpg)
Why increasing demands?
Increased demands
for animal-source food
More and more people
Continued urbanization
Growing middle classes
Globalization
Changing preferences

Steinfeld et al. 2006
Big productivity gaps -largely due to poor animal health
Some developing country regions have gaps of up to 430% in milk productivity
![Page 11: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/11.jpg)
Industrialization
• Increased profits
• Growth of off-farm income
• Reduction in greenhouse gases per unit of animal-source food produced
• Intensive units can maintain higher biosecurity
• Separates animals from humans
• Increased incomes may render people less vulnerable to disease.

The white revolution of India
Why?
• >1 billion people
• Many vegetarians
![Page 14: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/14.jpg)
The white revolution of India
• The leading milk producer (since 2001)
• The biggest fleet of cows and buffaloes in the world

Milk consumption in India
• Milk consumption 46 kg per capita in 1983 - 62 kg per capita
in 1997-106 kg in 2011-12
• Estimated total annual consumption of 60 million megatons
• India consumed 13% of the milk in the world
![Page 17: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/17.jpg)
Food-borne diseases
• Food-borne diseases are very important
• 1.4 million children die every year of diarrhea
• The majority is food and water-associated
![Page 18: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/18.jpg)
Risks and benefits with urban dairy
Good and bad
• Milk is nutritious
• Closeness to the market, farm inputs & services
• Lesser cost & time for transportation
• It is an opportunity to provide food for the family and an income
• Local markets for live/ dead animals
• Poor sanitation & inadequate space for farm waste disposal
• Living in close proximity to the animals kept
• High density of people and animals
![Page 19: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/19.jpg)

In practice
• Traders
• No difference in if milk was free from dirt (3.5% were not)
• 82% of trained traders had clean clothes, compared to 50% of untrained (p<0.001)
• Producers
• No difference in the number of milk containers were free from dirt (92% were not)
• No difference in if milk was free from dirt (2.5% were not)
• 79% of trained producers had clean clothes, compared to 68% of untrained (p<0.001)

Improving production- not always rocket science
• Follow up in 2014
• Trained farmers reported less diseases and higher milk production (p<0.001)
• No difference in Brucella prevalence
Average milk production in
liters per cow and day 2 years
ago/before ILRI training
Average milk production in
liters per cow and day now
Trained farmers 7.0 (range 2.5-10) 7.8 (range 3-15)
Untrained farmers 7.3 (range 2.5-14) 6.8 (range 2.5-14)

Moving forward
• Continue monitoring
• Continue evaluation of the training
• Mastitis frequency
• Antibiotic use, residues and resistance
• Animal health, welfare and productivity
![Page 35: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/35.jpg)
Project 2: Peri-urban milk production
• Can we affect the incidence of bovine tuberculosis?
• Can we affect the prevalence of antibiotic residues?
• Evaluate the risks
• Identify risk practices
• Pilot interventions
![Page 36: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/36.jpg)
Risk mitigation at the human-livestock interface
• It is possible to change people’s perceptions and habits- but difficult to assess the effect
• Farmers at high risk for zoonoses
• Milk is a risk product
• Assess the risks- mitigate the risks- increase the profits
![Page 37: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/37.jpg)
Mycobacterium bovis
• Tuberculosis can be caused by 2 bacteria, Mycobacterium
tuberculosis and Mycobacterium bovis
• Chronic disease in both humans and animals
• Fatal
• Difficult to treat
• Best method is to stop the spread
![Page 38: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/38.jpg)
Antibiotic residues
• Unregulated antibiotic
• Risk for antibiotic residues in the milk- there is no
testing, and no control
• The problem- residues or resistance
![Page 39: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/39.jpg)
Study design
1. Estimate the burden
Estimate the prevalence of Mycobacterium bovis,
Brucella abortus, Coxiella burnetii, Listeria
monocytogenes infection among livestock in small
holder dairy farms in peri-urban areas
Describe and quantify antibiotic use and associated
levels of milk production, including testing of pooled
milk samples for antibiotic residues
2. Design an intervention and pilot it!

Project 3: Animal health in Bihar
• Bihar is one of the poorest and least developed states
• Common farm size: 1-3 dairy cows or buffaloes
• 3-5 litres of milk
• Little known about the limitations to the dairy production
![Page 42: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/42.jpg)
Scoping study about the animal health problems
• Collecting morbidity and mortality data
• Including mastitis and antibiotic resistance
• Production and cost estimates
• Serology for selected diseases
• Brucella, leptospira, q-fever, haemorrhagic septicemia
• Special focus on Brucellosis
• Evaluation of rapid tests
• Molecular testing

Finding the best bet interventions
Identifying the limitations
Risk factors
Identifying what is feasible
Pilot
Evaluate sustainability and long term effects
![Page 44: Challenges in intensifying India smallholder dairy](https://reader030.vdocuments.mx/reader030/viewer/2022012701/61a3b2b5bd2178620b002145/html5/thumbnails/44.jpg)
Conclusions!
• Dairy very important in India and in spite of large efforts, productivity is suboptimal
• Milk products contribute to human morbidity
• Still much to do and a need for a one health perspective!
