Nitrogen retention and utilization de-
creased significantly when the rations contained
10 or 20% coffee grounds. Coffee grounds de-
pressed feed intake and weight gain. However,
Mather and Apgar (1956), who studied the use
of dried coffee grounds as a feed ingredient for
dairy cattle, reported that grounds did not af-
fect milk production but did reduce significant-
ly body weight of cows and growth rates of
calves on starter rations.
