Four metabolism and two finishing trials were conducted to determine the effects of imposed feed intake variation on acidosis and performance of finishing steers. In metabolism trials, intake variation of 3 lb DM/day increased acidosis of limit-fed steers as measured by ruminal pH. However, when steers were fed at ad libitum levels of intake, intake variation of up to 4 lb DM/day did not increase acidosis. In finishing trials, imposed intake variation of 4 lb DM/day neither decreased daily gain nor feed efficiency of steers fed at ad libitum levels of intake.
