Feed Analysis Packages by NIR[Highlights only]

Comprehensive Nutrition Analysis: Comprehensive Nutrition Analysis Package Information Sheet

  • The most inclusive Near-Infrared (NIR) analysis on the market
  • Includes Total Fatty Acids (TFA) and individual fatty acids
  • Includes Total Amino Acids (TAA) and individual amino acids
  • Includes multi-time point starch digestion analysis (0,3,7,16, and 24-hour) and an improved starch Kd
  • An easy-read results report incorporates 60-day and 4-year averages, and NDF and starch rumen digestion graphs

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

NIR Analysis for Commodity Feeds and Grain Mixes

  • Rapid and inexpensive options to understand commodity and grain mix variation due to vendor, date or time, or crop year
  • Two packages include: Comprehensive Commodity, Commodity and Grain Mix by NIR

                   -The Comprehensive Commodity package includes core nutrients and NDF digestibility measures

                   -The Commodity and Grain Mix by NIR package includes core nutrient measurements

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
