Feed Analysis Packages by NIR[Highlights only]

Comprehensive Nutrition Analysis: Comprehensive Nutrition Analysis Package Information Sheet

Beef Comprehensive Nutrition Analysis: Information Sheet

  • Includes all pieces of standard Comprehensive Nutrition Analysis (see above)
  • Includes a novel modified National Research Council (NRC) Beef Total Digestible Nutrients (TDN) value, and Net Energy of Gain (NEG) energy calculation

                    -Accounts for differences in starch digestibility, utilizing 7-hour rumen in situ starch digestion 

                    -Utilizes Total Tract Neutral Detergent Fiber Digestibility (TTNDFD) - a fiber quality appraisal - for more accurate Net Energy of Gain (NEG) calculations

                    -Supported by research from Dr. Garland Dahlke of Iowa State University

Fecal Comprehensive Nutrition Analysis

NIR Analysis for Commodity Feeds and Grain Mixes

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
