Abstract

Sixty-four stocker steers were offered endophyte-free fescue hay ad libitum, with either bromegrass or high-endophyte fescue seed screenings and supplements with or without Amaferm8 (Aspergillus oryzae fermentation extract). Steers offered bromegrass seed screenings gained faster (P<.01), consumed more feed (P<.01), and converted feed dry matter to gain more efficiently (P<.01) than those fed fescue seed screenings. Amaferm did not affect stocker performance or reduce rectal temperature. Therefore, feeding high-endophyte fescue screenings reduced intake and daily gain, and Amaferm did not offset those effects.
