Answer
D.
40 - 50%

Answer: Option C

Solution

Answer: Option C
Solution:
TDN in legume fodder is 30 - 40%.
The TDN value represents the utilizable energy content of feedstuff and it is calculated as the sum of digestible carbohydrate + 2.25 × digestible lipid + digestible protein.
TDN is determined by multiplying the digestion coefcient for organic matter, D, by a conversion factor calculated by the formula: F = M (0.01 + 0.000125 E) where M is the per cent organic matter in the dry matter of the feed and E is the ether extract as per cent of the organic matter.
