A dairy cow produces 25 L of milk per day while consuming 20 kg of dry‑matter feed, giving a feed conversion ratio (FCR) of milk (L) per kg DM. The farmer aims to increase milk yield by 20 % without changing feed intake. (a) What will be the new FCR? (b) Typical FCR values for dairy cows range from 1.2 to 1.5 L kg⁻¹. Is the required FCR realistic? Justify.

Answer Options

A. New FCR=1.2 L\/kg, which falls below the typical range and is therefore unrealistic.
B. New FCR=1.8 L\/kg, which exceeds the typical range and is not realistic.
C. New FCR=1.0 L\/kg, which is well within the typical range and thus realistic.
Correct Answer D. New FCR=1.5 L/kg, which is at the upper limit of typical range and therefore marginally realistic.
Correct Answer
D
Correct Option:
New FCR=1.5 L/kg, which is at the upper limit of typical range and therefore marginally realistic.
