Minnesota dairy farmers blame overloaded power lines and stray voltage for making their cows sickMINNEAPOLIS - As dead cow No. 79 lay stiff in a tractor scoop one recent cold morning on Greg Siewert's dairy farm, it was pretty clear in the nearby sick barn which would become No. 80. Wobbly on three legs, the fourth swollen and kinked at her side, a cow stared out below stooped shoulders, her black and white coat hanging dull and low from a grim row of ribs.
