In a day, a 1,500-pound Holstein cow consumes about 38 pounds of silage, 10 pounds of hay, 27 gallons of water and 38 pounds of grains and other feed.
So if all that goes in in a day, then what comes out? It's better than you might think.
That same cow is capable, in a day, of producing enough milk for 150 glasses, four pounds of butter, eight pounds of cheese or seven gallons of ice cream, according to an agricultural trailer on display Saturday at the Western Maryland Research and Education Center.
The trailer, filled with agriculture educational displays and activities, was featured in the center's first open house.
The 500-acre center near Keedysville is part of the University of Maryland's College of Agriculture and Natural Resources.
The open house was set up to teach people about the role of the center, Director Frank Allnutt said.
"It's geared toward the general public - to show what we do here and what the college does," Allnutt said.
