this is some footage i shot of cnn shooting footage of us.  the crew took several hours of footage at both farm burger and at fowler farm, so clearly a lot of action was cut out to make the final product. 

in this clip, farmer j is explaining our use of temporary electric fencing and rotational grazing in the context of how the great wild herds around the world evolved to graze. 

the fences mimic predators—always lurking on the perimeter—and the predators cause the herd to graze in a tight formation. 

this mob grazing has long term and exponentially beneficial effects on the pasture through an even distribution of both grazing and hoof impaction by the herd.  furthermore, the biggest, strongest, swiftest, and smartest of the bunch will avoid the predators most effectively—grazing in the center, and pushing the weak to the edges to their likely respective deaths.  natural selection at work.

in attempts to mimic this system, a good grazier will identify these instincts in his own domestic herd and cull—slaughter, removing from the gene pool—to improve overall herd quality.

nature is our instruction manual.
