CANNED GRASS FOR COWS
AMERICAN METHODS Canned grass, for winter eating, is the newest addition to the American cow’s bill of fare. The cans are Bft. in diameter and 25ft. high, and are m£)de of boiler iron. Freshly-mown grass is hustled through a silage cutter, and dry ice is mixed with it as it goes into the cans. The ice cool's the grass, changes to gas, drives out the air, and stops fermentation.
Sliding, rubber-edged tops settle down with the grass and allow the air to escape around their edges, but prevent entrance of outside air.
The 651 b. of dry ice which is required per ton of grass costs Cs Cd.
