The Sulfur Dioxide Preservation of Grass Silage

Abstract

Grass silage prepared from timothy-red clover and preserved with 5 lbs. of sulphur dioxide per ton of green material was equal in feeding value in terms of milk production and gains in body weight of dairy cows to similar material preserved with 200 lbs. of hominy per ton of green material. Because of the carotene content, palatability, ease of handling, feeding value of silage preserved with it and low cost, it appears that sulphur dioxide may be of value in the preservation of grass silage.
