Implication

Replicated Latin square study demonstrates improved ruminal fiber degradation kinetics in cannulated beef steers, suggesting enhanced digestion of high-quality fiber.

Key Points

Ruminal degradability of high-quality fiber fractions increases in beef steers supplemented with bacterial direct-fed microbial Treat-A, enhancing digestion.
Effective degradable fraction of neutral detergent fiber increases (P = 0.02) under Treat-A, and the hemicellulose potentially degradable fraction expands.
Replicated 3 × 3 Latin square design evaluates six cannulated beef steers fed a steam-flaked corn finishing diet, tracking in-situ degradability over 96 hours.
Highlights potential for direct-fed microbial blends to enhance ruminal fiber disappearance, though post-ruminal nutrient disappearance warrants further assessment.
