Cattle producers are looking at their hay supply for the colder months. For some, that means it’s time to start considering the purchase of hay, but is all hay the same? The answer is simply, no. For example, the University of Missouri Extension states that Missouri ranks fairly high in the nation in hay production, but that hay is not always the greatest quality. Missouri excels in cool season grass or fescue hay, but falls around 20th in the say of high-quality hay production, such as alfalfa. No matter what type of hay a producer buys or feeds, it should be tested. to a dry matter basis. Using the dry matter basis results allows for accurate comparison between wetter vs. drier feeds because the water content of the hay or silage is excluded from the reported dry matter nutrient results. Crude protein, the item most producers seem more concerned about, is estimated by measuring the amount of nitrogen in the sample and multiplying it by 6.25. This factor is used because most forage stem and leaf tissue proteins contain 16-percent nitrogen. Higher crude protein is usually better, but must be considered in the context of plant maturity, species, fertilizer rate and nitrate concentrations. Another major aspect of a hay test is the 417-863-8446 • 1-888-360-9588 Why is hay testing fiber analysis.

The voice of the Ozarks Forages furnish essential energy, proteins, vitamins, minerals and fibers in livestock diets. Factors such as variety, maturity, growing conditions, handling practices and so on affect forage quality prior to the time it is fed, according to Oklahoma State University Extension. Without proper testing, producers can overestimate or underestimate the feed value of forages. The lower the quality, the digestible portions) and some remains (the indigestible portions). The residues are reported as Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF). NDF provides an estimate of forage intake while ADF is used to calculate estimated energy levels in the forage.
