1Apparent degradability is the percentage of the nutrient degraded and true degradability is the percentage of the nutrient degraded discounting for the nutrient present in the bacterial pellet. DM, dry matter; OM, organic matter; CP, crude protein; NDF, neutral detergent fiber; ADF, acid detergent fiber.
2Levels of inclusion ranging from 0 to 90 g/25 kg of total mixed ration.
3Contrast: linear and quadratic, there was no cubic effect, thus P-values are not presented.
