Digestible Crude Protein of Wheat Straw

Question

DCP of wheat straw is-

Select an answer

DCP of wheat straw is-

  1. 0% — Correct Answer
  2. 0.62%
  3. 1.2%
  4. None
Explanation:
Correct Answer: 0%

Wheat straw is an extremely poor-quality roughage. Its Digestible Crude Protein (DCP) is 0% because although it contains a small amount of crude protein (3–4%), this protein has essentially zero digestibility.

Wheat Straw — Nutritional Profile
Parameter Normal Straw Urea-Treated Straw
DCP % 0% 4–5%
CP % 3–4% Increased
TDN % ~40% ~50%
Digestibility % ~46% ~70%
Straw Treatment with Urea
  • Treatment: @4% of straw (100 kg straw + 40 L water + 4 kg urea)
  • Water:Urea ratio should be 10:1 for optimum utilisation
  • Urea treatment improves N content, DCP, TDN and digestibility significantly
Straw and Stover — General Facts
  • Deficient in all minerals (Ca, P) but rich in silica
  • Low protein, low energy (TDN ~40%)
  • High crude fibre, low digestibility
Why Other Options Are Wrong
  • 0.62% → this is above the actual digestible protein value for wheat straw; straw has 0% DCP
  • 1.2% → also overestimates; wheat straw DCP is 0% in standard tables
  • None → incorrect; DCP of wheat straw = 0% is the established Indian feeding standard value
