To investigate whether Bacillus-based direct-fed microbials can reduce blood stress markers in feeder-calves during a 60-day feedlot program.
Eighty-four Angus calves were weaned and transported to a feedlot.
Calves were randomly allocated to receive either Bacillus-based DFM or a control treatment.
Blood samples were collected at multiple time points for biomarker analysis.
Calves receiving Bacillus DFM had lower plasma cortisol levels on day 14 compared to controls.
Plasma haptoglobin concentrations were also significantly reduced in the DFM group.
No significant effects were observed for plasma glucose, serum non-esterified fatty acids, and beta-hydroxybutyrate.

No takes yet. Share an insight, caveat, or question.

Supplementation with Bacillus-based DFM reduces stress markers in feeder-calves, suggesting improved welfare and adaptation.

Limede et al. (2026) studied this question.
