  IntroductionDr. David Mertens (2012), USDA-DFRC, proposed that the five most important nutritional measurements for hay crops are: dry matter (DM), ash, amylase-treated neutral detergent fiber (aNDF), some measure of digestibility or energy value, and crude protein (CP). More and more, these parameters can be estimated on-farm, or at least one can receive a flag as to when a parameter has ...

Phytate can be measured if a good data base of samples with chemistry exists to build the initial NIR Equation. The reliability and difference among equations for feed types depends on how the NIR equation is build. A reliable equation could be build to work across grain types. Many farmers have not bought real time NIR devices because of the cost and the extra time involved. I think it will e ...

Introduction Dairymen use feed and forage testing to reduce feed costs and maximize production. As such, accuracy of the feed tests are of great concern. The true objective of a forage or feed analysis is to predict animal performance from the forage and feed used in a ration formulated to meet nutrient requirements. This means that dairymen must consider, first, does the test relate to animal pe ...

Dr. Dan Undersander's research program has four major objectives that include: determining factors affecting alfalfa plant health and survival; best management for harvested forage - big bale wrapping, fermentation of silage; optimum management practices for intensively grazed pastures considering forage, yield, quality, and effect on wildlife; and developing equations for Near Infrared Reflectance spectroscopy for release to commercial forage testing laboratories.
