As carotene and nitrogen contents of pasture herbage are associated, experiments were designed to investigate the relative values of artificially dried grass, grass silage and normal winter rations for stock, and their effect on butter and milk production. It is found that the yellow colour of butter (an indication of its carotene and vitamin A content) is not materially affected by grass silage.
