Feed conversion efficiency is a measure of how much feed is required to produce a certain amount of a desired output. Such outputs may be animal weight, the amount of milk or meat produced, or even nutritional value measured in calories or grams of protein. It is a metric used to compare animal breeds and species in terms of their ability to convert feed into food available for human consumption.
