Spread the forage evenly on the plate and place To test the moisture content of corn silage withĪ microwave oven, weigh out exactly 100 grams ofįresh silage on a paper plate (Don't forget toĪdjust for the weight of the paper plate). Measuring moisture content with a microwave oven Maturity and storage facility you choose for you Theĭesired feeding program may influence the The kernels) that changes rumen dynamics. Plant digestibility but now the energy is comingįrom an entirely different source (starch from Harvesting later (2/3 to ¾ milk line with someīrown leaves) will mean about the same whole (from lower percentage of kernels), while Yield more digestible stover and less starch Sugars, and less digestible fiber than earlier With harder seed coats, more starch and less Mature corn silage will have more, drier grain Other considerations for timing the harvest ofĬorn silage are that as the corn plant matures, Gallons to add = ( - FW )/(8.33)įDM = desired final dry matter (e.g., 0.35) Of forage to 65% moisture (35% dry matter): Matter would require 137 gallons of water to getĪmount of water needed to raise moisture content For example, using the equationīelow, a 4000 lb load of silage at 45% dry Often, adding water to a dryįorage becomes impractical because of the amount In dry, overmature corn silage the stove is less Source: Wiersma and Carter, University of Effect of harvest stage on yield and quality of corn silage. Recommended moisture contents for corn silage stored in various Protein levels decline, fiber levels either remain constant or decline,Īnd digestibility remains relatively constant (table 4). Harvest is delayed from full dent to black layer (no milkline) crude In addition, the kernels become harder and less digestible. Silage that is too dry will haveĪir pockets that prevent anaerobic fermentation and allow molds toĭevelop. Seepage removes nutrients, particularly soluble nitrogen andĬarbohydrates, and can damage the silo. Silage ensiled too wet may ferment poorly and seep. Table 3 will promote good packing and will minimize losses due to Corn should be harvested for silage at a moisture content that willĮnsure good storage in the silo.
