in the last. Bermuda hay made up a large part of the total dry matter intake during the last 47 days of the trial. Daily intake of protein should have been very adequate in the early part of the test, but would have declined to marginal levels during the last 56 days due to the weather related failure to grow green forage. The overall response to providing 200 mg. of monensin to cattle grazing fescue, later supplemented with bermuda hay, was excellent in a 112-day test conducted in southeast Oklahoma. Some question remains as to the response on high vs. low quality forage, but it appears that the response was larger as the forage quality was lowered.
