A farmer intends to raise 120 chickens to a market weight of 2.2 kg each within 8 weeks. Each chick starts at 0.5 kg. The average daily gain (ADG) depends linearly on the protein content of the feed: at 18 % protein the ADG is 30 g day⁻¹ and at 20 % protein the ADG is 35 g day⁻¹. The feed conversion ratio (FCR) varies with protein according to \(\text{FCR}=1.8-0.05\times(\text{protein}\% -18)\). Determine the minimum protein percentage required in the feed to meet the target weight and, using that protein level, calculate the total amount of feed (in kg, rounded to the nearest kilogram) needed for the whole flock.

Answer Options

A. Minimum protein ≈ 17.8 % ; total feed ≈ 380 kg
Correct Answer B. Minimum protein ≈ 18.14 % ; total feed ≈ 366 kg
C. Minimum protein ≈ 19.2 % ; total feed ≈ 400 kg
D. Minimum protein ≈ 18.6 % ; total feed ≈ 350 kg
Correct Answer
B
Correct Option:
Minimum protein ≈ 18.14 % ; total feed ≈ 366 kg
