A 200‑kg farm animal receives 5 kg of feed per day. The feed contains 12 % protein. Calculate the amount of protein (in grams) the animal receives per day per kilogram of its body weight.
Answer
3 g/kg
The correct answer is 3 g/kg — Divide by animal weight: 600 g ÷ 200 kg = 3 g/kg
Step-by-step solution
- Convert feed to grams: 5 kg = 5000 g
- Compute total protein = 0.12 × 5000 g = 600 g
- Divide by animal weight: 600 g ÷ 200 kg = 3 g/kg
Common mistake: Dividing grams of protein by weight in kilograms without converting units or mis‑computing division
Concept tested: Protein intake per body weight
