2. Structure of Presentation
• Feed costs as challenge to livestock producers and
therefore animal nutritionist
• Improving economics of feeding through animal nutrition
approaches
• Feed resourcing and feeding at the interface where
positive and negative effects from livestock are
negotiated
• Feed interventions and wider livelihood implication
3. Share of feed costs in total costs of dairy
production
(Hemme et al. 2013)
5. Feed Price and Milk Farm Gate Price
Developments in India
(GAIN Report IN7123, 2018)
6. Feed Costs as Challenge
• Feed costs already the major input cost into livestock
production
• Global and India feed prices diverge to the detriment of
the latter
• Feed prices in India rise faster than farm gate prices of
produce, producing a scissor effect
7. Improving economics of feeding through
animal nutrition approaches
• Importance of feed quality –price relations, develop a
culture to combine both information
• Improve feed biomass quality: support plant breeding,
upgrading ligno-cellulosic biomass
• Improving on-farm feeding, matching and balancing
nutrients and animal performance
8. Feed quality –price relations
Variations in prices in 65 compound and concentrate feeds
collected in Bihar in 2015 accounted for by CP, NDF,
ADF, ADL, IVOMD,ME and Fat using
stepwise multiple regression
(Singh et al. 2016)
Feed quality traits Partial R2 Total R2 P < F
Metabolizable Energy 0.155 0.155 0.001
Crude Protein 0.076 0.231 0.02
Feed dependent estimates to produce on additional kg of milk
ranged from 10.3 to 24.5 IRs
9. Forages and (in)attention to their quality:

Forage N (%) 2.00 1.55 - 2.22
Forage IVOMD (%) 49.1 42.3 - 53.4
Highly successful for example in
Mulkanoor Woman Dairy Co-operative!
But do we need to settle for a mean
IVOMD of below 50% in a green forage ?

12. Leveraging spin-off technologies from 2nd generation
for deconstructing ligno-cellulosic biomass
• 10 – 50 Billion tons biomass annually
and about 4 Billion tons are from
crop residues
• Billions of $ investment to leverage
for different steps along the value
chain starting from collection of high
bulk low density feed stocks to bio-
manufacturing and de novo synthesis
of enzymes
• Dissolve boundaries between food-
feed-fodder, livestock species and
even animal and human nutrition
• Potential game changer technologies
13. Efficient harvest and collection of high volume-low density
biomass
Balance central versus decentralized approach
Optimize physical form-transport-susceptibility to pre- treatment-
voluntary feed intake
Swell and disrupt hemicellulose-cellulose-lignin matrix
Partially hydrolyze xylan structure
Increase surface and porocity of fiber structure
Unclear benefit for ruminant nutrition, more research with new

18. Improve feed biomass quality: support plant
breeding, upgrading ligno-cellulosic biomass
Improving economics of feeding through
animal nutrition approaches• Co-operation of animal nutrition and plant improvement
can contribute significantly to more feed biomass with
higher fodder quality
• Potential game changer technologies to be harvested
from 2nd generation biofuel - animal nutritionists
need to be the driver!
19. Improving on-farm feeding, matching and
balancing nutrients and animal performance
performance
nimal nutrition approaches
Ration Balancing: a comprehensive approach of NDDB to apply
animal nutrition principles to improve on-farm feeding:
• Increase in production
• Increase in economics of dairy and its components
• Positive associated effects

21. Improving on-farm feeding, matching and
balancing nutrients and animal
performance
nimal nutrition approaches
• Ration Balancing applied to millions of dairy animals had significant positive
effect on key dairy productivity variables
• The comprehensive approach of NDDB to apply animal nutrition principles to
improve on-farm feeding has general appeal to LMC countries –
South to South collaborative opportunities
• A serious study is warranted (and facilitated) to understand if current findings
describe ceiling values for what is achievable through on-farm
targeted feed interventions

environmental foot prints

production

28. Feed resourcing and feeding and
environmental foot prints
Structure of Presentation
• Feed sourcing is the driving factor for livestock water
productivity
• With awareness, animal nutritionist can estimate water
requirement and design water use efficient rations
• Ration choice and design effect SCFA proportion and EMP
and both effect enteric CH4 production
• Intensification has potentially an overriding effect on
feed requirement and total and proportional
CH4 production
29. Feed interventions and wider livelihood
implications
• Feed interventions, feeding and labor
• Limitations to improvement of feed resources on-farm
• Need to increase affordable off-farm produced feed
• Win-win situation through production of affordable off-
farm produced feed

villages, India)
34. More off-farm produced feed and its
implication for wider rural livelihood
implicationsForages as a cash crop
• Simple, low biophysical and socio economic investment
• Highly competitive for example with vegetables
Fodder marketing, service provision
• Fodder collection and transactions
• Chopping, grinding
• Silage, hay making
Feed processing
• Mineral and other supplements
• Total mixed rations
35. Conclusions
• Increase the economic benefit from ASF production by decreasing feed
costs and/or increasing ASF production,
• Decrease the environmental footprint of ASF production
• Reduce labour requirements and drudgery involved in feed resourcing and
feeding
• Provide opportunities for micro, small and medium enterprises (MSME) in
feed production, marketing and processing
36. Conclusions
However to achieve this we need to work within a wide
disciplinary and institutional framework:
• Economists and socio-economists
• Natural resource management
• Plant improvement
• Key life science actors
• Development actors, NGOs
• Private sector
• Policy makers
