The technique was troscopy (NIRS): efficacy of broad based calibration equations. J. Dairy Sci. â first applied to measure moisture content and was devel- Akin, D. E., and A. Chesson In order to determine the nutrient content in forage it is best to take samples and get them analyzed by a forage testing lab (contact your local County Extension Office for testing information or see the fact sheet, FS, Analysis of Feeds and Forages for Horses). Legumes are usually higher in protein, calcium, and energy than grasses.
The aim of the chapter was to evaluate and predict the nutritive and feeding value of unknown and underutilised forages. Underutilised forages were collected from various regions. Chemical composition and degradability of forages in the rumen were determined. A dataset was created bearing degradability parameters of feeds from 40 studies. Using the dataset, a step-wise regression . For dairy and beef producers, rye can also be considered for additional grazing or forage value. Based on surveys from several Northwest Ohio producers who have used rye as a spring feed source, it can provide additional feed tonnage on idle acres in a corn-soybeans rotation and with minimal effort or expense.

Our data ( Nebraska Beef Report pages ) suggest that DGS are % of the feed value of corn in forage-based diets. Final Thoughts. Sampling forages and understanding a forage analysis will result in supplementation strategies that meet the cows' nutrient requirements, but also will impact profit potential of the enterprise.
Knowing the moisture content of forage assures the buyer of its nutritional value and the seller of its fair market value.
A Pacific Northwest Extension Publication Oregon • Idaho • Washington Valuing Forages Based on Moisture and Nutrient Content T. Downing and M. Gamroth THIS PUBLICATION IS OUT OF DATE. For most current. 22 _____ Beef Cattle Nutrition Workbook Chapter 2 • Forage Value Book values and Extension publications It has long been recognized that book value nutrient analyses for forages grown in other parts of the country do not accurately represent Oregon forages.
In general, haylage has a moisture content of between 15 percent to a maximum of 40 percent (60 to 85 percent DM). Silage has a moisture content of more than 40 percent (DM less than 60 percent). Both haylage and silage can be found in plastic-wrapped round bales. In silage with the higher moisture content, the preservation of the forage is as.
DM content, simply subtract the moisture content from Forage and feed nutrient composition can be eval-uated on a DM or as fed (as received) basis. The as-fed basis includes moisture content in each nutrient listing. For a given sample, as-fed nutrient values are always smaller than DM nutrient values.
Most nutritionists prefer to view. value of concentrate relative to forage. The NIR analysis method does not estimate the energy (TDN) content to wet (WDGS) or dry (DDGS) distillers grains.
plus solubles very well. Our data suggests that WDGS and DDGS are percent the energy value of corn in forage diets.
Therefore if corn is 90 percent TDN on a dry-matter basis then. Dry matter: Typical dry matter (DM) values are shown, but the moisture content of feeds can vary greatly. Thus, DM content can be the biggest reason for variation in feed composition on an “as-fed” basis.
For this reason, chemical constituents and biological attributes of. The forage of both of these grasses can support high dry matter intake levels and are suitable for animals with high nutritional requirements, including lactating dairy cattle.
With good fertility both species provide rapid growth during periods of cool temperatures and when sufficient levels of soil moisture. A basic hay analysis costs about $ Optimum horse hay moisture ranges from 10 to 16 percent. ADF values between 30 and 35 percent are good for horses.
NDF values between 40 and 50 are good for horses. The adult horse at maintenance should have a Ca to. High-quality forages are essential for livestock, as premium products provide the optimal amounts of energy, protein, minerals, fiber and other essential nutrients.
Forage quality relies upon many factors, including climate, soil fertility and harvesting technique. Production of premium forages is extremely complex.
Methods of estimating or analytically determining nutrient content of forages include visual appraisal, chemical analysis, and near infrared reflectance spectroscopy.
Each method has strengths and weaknesses for use in selecting hay for horses. Visual appraisal is the oldest and most common method of selecting hay. Forage appearance is. When purchasing feeds, most sales are based on an “as-fed” basis which includes the moisture.
Since moisture content varies between forages, it is best to adjust to a DM-basis whenever possible to avoid paying for excess water.
When storing forages or grain, knowing moisture content helps to understand if spoilage or poor fermentation may. Start studying Animal Nutrition - Forages. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Search. What forage moisture content allows for minimum storage and harvesting losses. 50 - 60% What value does neutral detergent fiber represent. These calculations are based on crude protein (CP) and net energy lactation (NE l) content of the forages.
Forage DMI is calculated using a forage neutral detergent fiber (NDF) intake of 1% of body weight. Projected milk production is based only on the nutrients contained in the forage after accounting for the animal maintenance requirements.

NIR on-farm – moisture “NIR is a very robust technology used around the world to predict organic bond based constituents,” says Goeser.
“The moisture tool uses a reflective wavelength of light which is bounced off the forages. Some of the light is reflected back, which in turn relates to the moisture content. Based. or forage as it is fed to the animal including the moisture content. While as fed is an accurate representation of the feed being offered, it does not provide a good indication of the nutrient composition of the non-water feed components, particularly when the moisture content is high.
Consider the following examples of converting “as fed. As a general rule, forages would be 70% or above DIP and therefore 30% or less UIP. These values change based on maturity and type of forage. Corn is about 45% DIP and 55% UIP meaning if corn is 10% crude protein, that 45% of the 10% is DIP and 55% of the 10% is UIP.
Urea is % DIP. Triticale can have a uNDF value ranging from 15% to 30% of dry matter. Rye forage typically provides the lowest uNDF of the small grain species and will often have a uNDF value even lower than a good corn silage.
Rye, however, can be difficult to harvest at the right stage and moisture level given weather conditions in early spring. All nutrient conversions from one basis to another can be set up using equivalent ratios as shown in Figure 2.
The known nutrient value for a given dry matter expression (dry matter, as-fed or air-dry basis) is placed over its associated and known dry matter percentage to establish the .It’s hard to create a ration for beef cattle without a forage analysis since nutrient values can vary so much, even within the same type of plants.
Brome grass hay could be 6 percent protein or as high as 12 percent, depending on stage of maturity and weather conditions while growing and during harvest.Nutrient contentOnce digested, will the forage provide an adequate level of nutrients?
Living forage plants usually contain 70 to 90% standardize analyses, forage yield and nutrient content are usually expressed on a dry matter (DM) dry matter can be divided into two main categories: (1) cell contents (the non-structural.
