What is feed efficiency?

Explanation:
Feed efficiency measures how well feed is turned into body mass. It’s about how much feed is needed to gain a unit of weight. If an animal requires less feed to gain the same amount of weight, it has better feed efficiency. That’s why the statement describing the amount of feed needed for growth best captures this concept. The other ideas—growth in weight alone, permanent marking, or an ID device—don’t reflect how efficiently feed supports growth. In practice, people also talk about how much growth you get per unit of feed, or the feed conversion ratio (lower is better) or the feed efficiency ratio (higher is better).
