Methods of improving the utilization of cereal straw by ruminants. III. A note on the effect of ensiling straw treated with urea

Straw treated with urea was offered to lambs either freshly prepared (EN₀) or after ensiling with urea for 30 days (EN₃₀). The lambs also received 10 g dry matter (DM) of shredded, artificially dried grass per day per kg of metabolic liveweight. Ensiling straw significantly increased its intake from 32 to 41 g DM per day per kg of metabolic liveweight, and its DM digestibility from 375 to 450 g per kg.
