Question

To meet the copper requirements of a growing pain, the feed must contain 4 mg copper per kilogram of dry matter of feed. If a pig is eating 5 pounds (on a dry matter basis) daily, how many milligrams of copper is the animal consuming?

a) 15 mg
b) 20 mg
c) 9 mg
d) 10 mg

Answer 1

option (c) 9 mg

Explanation:

Data provided:

Amount of copper that must be contained in the feed = 4 mg per kilogram

Amount of dry matter being consumed by the pig = 5 pounds

Now,

1 pound = 0.45 kilograms

thus,

5 pounds = 0.45 × 5 = 2.25 kilograms

thus,

amount of dry matter being consumed by the pig = 2.25 kg

therefore,

the amount of copper consumed = 4 mg per kilogram × 2.25 kg

or

the amount of copper consumed = 9 mg

Hence,

the correct answer is option (c) 9 mg
