Demand for crop residues
• feed demand and supply scenarios, fodder marketing
Exploit existing variation
• example sorghum but valid for most key cereal and
legumes
• mainstreamed in some, taken on board in most crops
(NARES, CRP, PS)
• includes grains
Targeted enhancement
• conventional breeding (recurrent selection,
hybridization) molecular breeding, genetic selection
Price premium for quality stover
Dairy rations based on lower (47%) and higher (52%)
