If a flock has an FCR of 1.8 and another has 2.0, which is more feed-efficient?

• A. 2.0
• B. 2.0
• C. 1.8
• D. 3.0

Answer: (A)

Lower FCR means better feed efficiency. Feed Conversion Ratio (FCR) is the amount of feed needed to gain a unit of body weight. So, a lower number means less feed is required for the same weight gain.

Between 1.8 and 2.0, the flock with 1.8 needs less feed per unit of weight gained, making it more efficient. For example, to gain 100 kg, the 1.8 flock would need about 180 kg of feed, while the 2.0 flock would need about 200 kg. Higher FCR values indicate less efficient conversion of feed into body weight.
