Quick rotational grazing with 2 days/plot, on average.
Going from a 5 days/plot rotational grazing to a 2 days/plot to better use grass and increase grasslands valorization.
The plots are 1 ha large on average with 4 moves of 45 dairy cows in 2 days. Fencing with movable wires and setting of complementary water troughs.
The decision to use rotational grazing was taken with Bongrain with regard to the « Carbon footprint »: pilot farm where one thinks about the heifers’ rearing length (age at first calving), the concentrates consumption, the valorization of grass…
Reason for the innovation
The farmer’s strategy is set up regarding a cost reduction.

Why it is working
The will of the breeders in the implementation of this innovation is the first factor of success. They wish to do reasonable things with a good distribution of workload and autonomy of the current system.
