Abstract
A feedlot study with individually fed steers (n=60) was conducted comparing a natural feed additive (Direct Fed Microbial) to no feed additive (control) on performance and liver abscess rate of finishing beef cattle. There were no significant differences between treatments on intake, gain, feed conversion, or hot carcass weight and carcass traits. Liver abscess occurrence and severity were similar for both treatments with 4/29 steers having abscessed livers in the control group and 3/29 steers in the group that received direct fed microbials. The direct fed microbial feed additive fed in this exploratory study did not significantly affect performance, liver abscess rate, or the severity of liver abscesses of finishing beef cattle.
