Implication

Trial shows Bacillus licheniformis and Bacillus subtilis improve nutrient breakdown in high-concentrate diets for cows, indicating benefits for beef production.

Key Points

Evaluate the effects of Bacillus-based microbial supplementation on nutrient degradation in beef cows.
Used 15 rumen-cannulated cows in a randomized design.
Supplemented diets with Bacillus licheniformis and Bacillus subtilis.
Measured nutrient disappearance using in situ methods with Dacron bags.
Bacillus supplementation increased dry matter and NDF disappearance in some diets.
Fraction B degradation was greater with Bacillus compared to control.
No significant differences for NDF degradation were observed.
