Abstract
Objective
The objective of this research was to determine the influence of Bacillus subtilis PB6 administration had on growth performance, carcass traits, and Salmonella prevalence in yearling steers placed on feed in March in southeastern South Dakota that were not subjected to marketing or environmental stressors during the finishing phase.
Study Description
Yearling crossbred beef steers (N = 238; initial shrunk BW = 886 ± 68.8 lbs) were used in a 140-d finishing study at the Southeast Research Farm (SERF) in Beresford, SD. Steers were allotted to one of 24 pens (N = 9 to 10 steers/pen) and assigned to one of two dietary treatments (12 pens/treatment): no probiotic (CON) or 0.5 g·steer-1·d-1 of a Bacillus subtilis PB6 probiotic (CLOSTAT®500, Kemin Industries, Des Moines, IA; CLO). Data were analyzed as a randomized complete block design and pen served as the experimental unit; an α of 0.05 determined significance.
