Abstract

One hundred forty-four predominantly Angus x Charolais steers were used to determine effects of different feeding regimens on performance, behavior and tympanic temperatures of steers under environmental heat stress. Steers were assigned to one of three treatments: 1) ad libitum fed at 0800 hr (ADLIB); 2) fed at 1600 hr with bunks slick by 0800 hr (BKMGT); and 3) fed 85% of predicted DMI at 1600 hr (LIMFD). Treatments were imposed for 23 days after which all steers were allowed ad libitum access to feed at 0800 hr. Overall performance was not affected by treatment. Altering feed time and amount reduced tympanic temperature and altered eating pattern.
