Outline of presentation Background Materials & methods Results & Discussion Conclusion Acknowledgments
Introduction 50% livestock sector & Livelihood to many Hh Low productivity due to inadequate nutrition Scarcity & inappropriate utilisation of available
feed resources Knowledge on feed formulation rarely used Ration formulation programmes : DRASTIC Objective: Benefit of precise feed formulation
Materials & MethodsFigure 1: Flow diagram of feeding trial
Diet I = FMC+ Basal
Diet II = MUM + Basal
Diet II = BSG + Basal
Diet IV = Farmer’s practice

Conclusion
Precise ration formulation improved
the milk production and farm profits
BSG is as effective as FMC or MUM
Choice should be based on
availability & cost
