Description: Direct-fed microbials (DFM) are probiotic supplements fed to cattle to alter the rumen microbiome and improve health and performance (Uyeno et al., 2015). Inclusion of DFMs in feedlot diets has variable effects ranging from no improvements in average daily gain to reduced performance in some feeding systems (Wilson et al., 2016; Swanson et al., 2018). In this issue, two DFMs were assessed for their ability to alter nutrient digestibility and blood parameters (Ugunade et al., 2020). Although no effects were evident on total tract digestibility, the DFMs increased blood glucose suggesting improved energy status.
