Key findings from sorghum stover fodder trading

High monetary value of stover, ratio grain: stover monetary value getting narrower

Apparently “small” differences in fodder quality can command surprisingly high price premiums

Interesting trans-regional similarities in price premiums

Key findings from value addition to stover and

bagasse Quite respectable levels of livestock productivity

possible on almost completely sorghum by-product based rations

No processing solution feeds fit all feeding situations

Economy driving, optimizing strategies required

More emphasis needed on decentralized processing options

19

Where to go from here: improve fodder trading of

stover and bagasse Establish actor linkage matrices of participants in

stover and bagasse trading

Improve linkages between pertinent actors and implement appropriate communication lines for example mobile phone based

Identify and implement small scale stover and

bagasse processing options that suitable for prevailing labor and infrastructural conditions

Develop capacity for more efficient fodder trading

20

Where to go from here: value chain development for de-centralized feed

processing option

Targeting of districts based on dairy systems, fodder demand, cropping pattern, labor availability, alternative feed resources etc

Inventory available feed resource and determine feed price-quality relations

Field test and monitor economically viable and self sustaining de-centralized feed processing options for small scale business entrepreneurs and dairy cooperatives

Develop scaling up strategy
