CHO Metabolism. CHO Metabolism. CHO constitute 70% or more of the DM Major precursor of energy Partitioning CHO into fiber & non-fiber. CHO Metabolism. Optimal utilization of diets influenced by: - Chemical composition - Physical characteristics (particle size & density
- Chemical composition
- Physical characteristics (particle size & density
- Physical characteristics can influence: animal health, ruminal fermentation & utilization, &animal performance.
refer to ability of fiber to maintain milk fat production and animal health effectively
related to physical characteristics of fiber (primarily particle size) that influence chewing activity and the biphasic nature of ruminal contents (floating mat of large particles on a pool of liquid and small particles)
