- •
20 Commercial dairy farms fed a range of California early lactation rations.
- •
Data documents ranges of microbial protein outflow and plasma amino acid concentrations.
- •
Procedures provide a real time database as a benchmark for comparisons.
- •
Data provides guidelines for evaluation of diet formulations using models.
- •
Data can be used to identify rumen microbial growth and/or absorbable amino acid issues.
