In livestock farming, feed recycling is a measure that describes the feed consumption per unit performance.
In meat production, feed recycling indicates how much fodder is needed for one kilogram of growth. With a better feed recovery, less feed is needed per kilogram of growth, so feed consumption is declining and the efficiency of feeding increases.
In milk and egg production, feed consumption per litre of milk or per egg is relevant.
