Parameter Untreated Straw
Parameter Untreated Urea-treated
DCP% 0% 4–5%
TDN% 40% 50%
Digestibility 46% 70%
Mechanism

Urea hydrolyses to NH₃ + CO₂. NH₃ acts as alkali, breaking ester bonds between lignin and hemicellulose, increasing cell wall degradability. Urea treatment @ 4% of straw: 100 kg straw + 4 kg urea + 40 litres water (water:urea = 10:1).
