Relative feed value has been used for a number of years to indicate the overall feed value of forage. In recent years, there have been some changes considered to make this assessment more accurate in regards to predicting the feed value of forage.It is well accepted that there is a correlation between the acid detergent fiber (ADF) portion of forage and the energy value of the forage. One of the p ...

IntroductionFrom the moment the alfalfa is cut until it is delivered to the animal, biological and mechanical processes take place that decrease quantity and nutritional quality of alfalfa. Our goal is to conserve the digestible fiber, protein, and energy in the forage and to maintain protein in a form that can be effectively utilized by the ruminant.The approach is to harvest at the correct stage ...

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 ch ...

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 ...

IntroductionDairymen 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 perf ...
