Introduction The Céréopa, who are we?
The PerfAgro approach

PerfAgro An original way to grasp the issue
of sustainable performance
PERFORMANCE OF THE SYSTEM
4
PerfAgro A global approach which takes
simultaneously into account, into details, crop
and animal productions
Purchase of crop inputs
Purchase of livestock feed
Zones Yields Crop management Nutritional
properties Etc.
Diet in function of the age Grazing calendar Etc.
Various external transfers
Various external transfers
5
PerfAgro A global approach which gives diverse
and precise indicators of sustainable performance
Examples of output indicators
Economicmargin(/year)
Diets of dairy cows atdifferent stages
oflactation duringthe winter
Quantity of work(hours/year)
Fossile energyuse on the farm(MJ/year)
Constraints costs(milk quotafarm area, etc.)
Etc.
6
PerfAgro A new approach of questions which
widens the response spectrum
Example the issue of protein autonomy on a farm
Ration calculations to replace soya by rapeseed
?
CLASSICAL APPROACHES
PROTEIN AUTONOMY
With PerfAgro, many new opportunities appear gt
Choice of crop rotationgt Rapeseed crushing gt
Level of intensificationgt Etc.

PerfAgro A tool in development
Limited for the while to
DAIRY COW PRODUCTION
Being developed risks management, global energy
use on the farm minimization, bursts of work,
environmental indicators.

Conclusion
PerfAgro Beyond decision making
An approach of the complexity of agricultural
systems which gives the possibility to
benchmark varied breeding systems in different
situations
In France
and abroad
Sustainable agriculture a complex issue gt
Simplification is not always the best gt Why not
trying to get opportunities from it ?
