Feeding dairy cows whole cottonseed byproduct boosts milk fat, researchers find

Despite U.S. per capita-milk consumption falling significantly in recent decades, according to the U.S. Department of Agricultural, Americans are consuming a record amount of dairy in butter and cheese — products made from milk fat. In a new study, a team led by researchers at Penn State demonstrated that supplementing dairy cattle feed with 15% whole cottonseed, a byproduct of processing cotton for fiber, can increase milk fat concentration and yield.
