Discovery to delivery: Livestock and Fish
– Maize CRP Collaboration on dual
purpose maize hybrids
Michael Blümmel, PH Zaidi, M Vinayan and Babu Raman
ILRI Institute Planning Meeting
4-7 October 2016
Rationale
 Maize replaces sorghum in many rain-fed systems
 Concerns if maize can meet the typical dual purpose demand
expected from sorghum
Approaches
 Use conventional and molecular breeding to concomitantly
improve maize grain and stover traits
 Address maize stover use in the production system with dairy
producers, fodder traders, feed processors etc.
Genomic Selection

Blümmel et al., 2016
Is maize stover necessarily inferior to sorghum stover?
Dairy buffalo in peninsular India respond
Parameter Maize
stover
Sorghum
stover1
Stover offered (kg/d) 9.5 9.5
Conc. mixture offered (kg/d) 6.50 6.50
Milk yield (kg/d) 9.36 8.87
Income through sale of milk (Rs./d) 262.1 248.4
Cost per kg milk (Rs/kg) 14.5 18.2
1 Farmer paid 6 to 6.5 Rs/kg sorghum stover
However: transport costs favour sorghum
over maize stover
One DCM truck transports 2.4 tons of un-chopped sorghum stover but only 1 ton of un-chopped
maize stover. Chopping decreases this ratio to 1.5
Conclusions
 We, with partners, need to work concomitantly along all key entry
points in value chains
 At least one partner needs to have sufficient understanding of
key areas related around discovery to delivery
 Perhaps one of CGs real comparative advantages

Dual purpose maize hybrids for livestock feed

  • 1. Discovery to delivery: Livestock and Fish – Maize CRP Collaboration on dual purpose maize hybrids Michael Blümmel, PH Zaidi, M Vinayan and Babu Raman ILRI Institute Planning Meeting 4-7 October 2016
  • 2. Rationale  Maize replaces sorghum in many rain-fed systems  Concerns if maize can meet the typical dual purpose demand expected from sorghum Approaches  Use conventional and molecular breeding to concomitantly improve maize grain and stover traits  Address maize stover use in the production system with dairy producers, fodder traders, feed processors etc.

  • 6. Is maize stover necessarily inferior to sorghum stover? Dairy buffalo in peninsular India respond Parameter Maize stover Sorghum stover1 Stover offered (kg/d) 9.5 9.5 Conc. mixture offered (kg/d) 6.50 6.50 Milk yield (kg/d) 9.36 8.87 Income through sale of milk (Rs./d) 262.1 248.4 Cost per kg milk (Rs/kg) 14.5 18.2 1 Farmer paid 6 to 6.5 Rs/kg sorghum stover
  • 7. However: transport costs favour sorghum over maize stover One DCM truck transports 2.4 tons of un-chopped sorghum stover but only 1 ton of un-chopped maize stover. Chopping decreases this ratio to 1.5
  • 8. Conclusions  We, with partners, need to work concomitantly along all key entry points in value chains  At least one partner needs to have sufficient understanding of key areas related around discovery to delivery  Perhaps one of CGs real comparative advantages

Editor's Notes

  1. Four Topics: 1) demand as reflected by scenarios and in practice by fodder marketing, 2) what impact would it have if we address CR, 3) how to do it, 4) where to go
  2. The simplicity of the work-flow projected here masks the magnitude of shift it represents, when implemented successfully. I believe the GS approach and the specific genomic region based approaches can go hand in hand, complementing each other.
