Cows on semidesert grass-shrub range ate less than 1/2 lb/day of 3:1 meal-salt mix when it was fed 1 to 2 1/2 miles from water. No injury to cattle due to either inadequate or excessive salt intake was observed. Compared to feeding at water, placing salt or meal-salt 1 to 2 1/2 miles from water increased average utilization of perennial grasses where use was usually light, but it did not materially decrease use near water.
