A dairy cow produces 25 L of milk per day and consumes 22 kg of dry‑matter total mixed ration (TMR) per day. The TMR contains 16 % crude protein and provides 2.8 Mcal of metabolizable energy per kilogram. (i) Calculate the feed conversion efficiency (FCE) in kg milk per Mcal. (ii) Determine whether the cow meets the recommended minimum FCE of 0.9 kg Mcal⁻¹ and the crude protein requirement of 6 kg per day (assume 1 L milk ≈ 1 kg).

Answer Options

A. FCE = 0.41 kg Mcal⁻¹ (below 0.9); CP intake = 3.52 kg (below 6 kg) - diet meets requirements
Correct Answer B. FCE = 0.41 kg Mcal⁻¹ (below 0.9); CP intake = 3.52 kg (below 6 kg) - diet is inadequate
C. FCE = 0.41 kg Mcal⁻¹ (below 0.9); CP intake = 4.80 kg (below 6 kg) - diet is inadequate
D. FCE = 0.55 kg Mcal⁻¹ (below 0.9); CP intake = 3.52 kg (below 6 kg) - diet is inadequate
Correct Answer
B
Correct Option:
FCE = 0.41 kg Mcal⁻¹ (below 0.9); CP intake = 3.52 kg (below 6 kg) - diet is inadequate
