NIR Package Components of Interest
Unique aspects to Rock River Laboratory NIR nutrition analysis
Rumen in situ starch digestion: included in Comprehensive Nutrition, Dynamic CNCPS, and Corn Grain Digestibility packages
- Research-backed and accurate rumen starch digestion measure
- Proven more reliable than in vitro starch digestion
- Best reflects how cows will respond to starch in corn grain, snaplage or earlage, and corn silage
TTNDFD: Included in all NIR dynamic and comprehensive packages
- A real-time fiber digestion assessment tool
- Reflects real cow digestion and performance by forecasting how high-producing cows will respond to a new forage, before actually feeding it
- Proven through university in vivo digestion trials
- Licensed from the University of Wisconsin-Madison
