Q&A: How much feed value does whey from a cheese factory have for livestock?
Dr. Galen Erickson, Associate Professor of Animal Science, Animal Science, University of Nebraska
A: Whey can be fed to cattle and works quite well. The energy value is probably similar to corn or a bit less on a DM basis. If this is condensed whey (i.e, 50% DM or so), then the feeding will be a bit better in terms of energy than dried whey. However, the dried product is easier to handle.
