Delivered in the Bunk: Due to the ensiling process, corn silage will experience shrink and dry matter loss from 10% to 20% or more between when silage is packed into the silo and when it is removed to be fed. In addi-tion to a higher crude protein content, sunflower silage made from oil seed varieties contains 10 to 12 percent fat compared to 2 to 3 percent fat in corn silage. Assuming a silage-based feed ration requires 33 lbs (or 12 lbs DM) of barley silage per day for a beef cow in mid-pregnancy with a body condition score of 3.0, and silage yield is at 8 ton/acre (or 3 ton/acre DM); production from one acre of land can support three cows over a 150-day winter feeding period. Corn silage is somewhat tougher to determine a price on in comparison to other forages. If you know the silo size, how many feet of silage was put up and what the moisture was, silo charts can be used to calculate tons stored. A higher yield goal may be ap-propriate if management improvements are expected to result in increased yield. The BMR Corn Silage Calculator: What are the economic trade-offs for yield and quality? Corn has a decimal % moisture of 0.155 when a bushel of corn weighs 56 pounds. Many of the top hybrids for corn silage also work well for dry grain and high moisture corn applications. Then estimating a 180-bushel corn grain yield at $3.75 per bushel or a 23 tons per acre corn silage yield at 35% dry matter, the average of minimum price and maximum price is $30.75 per ton of silage. The land use efficiency of corn silage production has steadily improved since 1990, indicating increasing yields per acre harvested (Figure 1.3.4). In the Northwest, the USDA has not released corn silage estimates, but grain corn yields are expected to be lower in Washington and Idaho. Once stored, questions have come up on how to estimate the tonnage of silage in a bunker silo. At each estimation site, measure off a length of a single row equal to 1/1000th acre. ... Count and record the number of ears on the plants in the 1/1000th acre of row that you deem to be harvestable. ... For every fifth ear in the sample row, record the number of complete kernel rows per ear and average number of kernels per row. ... More items... Corn grain yield improves from 0 to 43 percent between full dent and black layer, with about 9 to 13 percent of the final grain yield determined after 50 percent kernel milk.

Additional charges or costs should be made to cover the additional costs such as fertilizer, harvesting and storing of silage compared to corn grain. It includes features for adjusting the corn silage price and estimating yield calculations. In Washington, grain corn yields are anticipated to be 12% lower. Best management practices (BMPs) for high yield potential and quality silage includes corn product selection, planting date, fertility, pest management, fungicides, harvest height, delivery rate, and harvest dry matter (DM) content. Normally corn silage is half grain and half stover. Hybrids that are later in maturity than this are at increased risk of not reaching the proper harvest stage for corn silage prior to the first killing freeze. Calculators offer a way for you to get customized measurements for your farm. Silage Price standing in field, wet basis (C÷1xU) Silage Price standing in field, wet basis (V÷100x2000) Value of standing crop (DxX) Table 1. Corn silage is a popular forage for ruminant animals because it is high in energy and digestibility and is easily adapted to mechanization from the stand-crop to time of feeding.Corn silage should have a light, pleasant smell with only a slight vinegar odor. of gluten meal (60% protein), and 1.5 lbs. Having an on-farm scale and weighing loads is the gold standard to determine silage yield, but … To better understand the economic effect of bmr corn in dairy operation, Dr. Randy Shaver et al. AMES, Iowa — Those who use silage in their beef rations are invited to consider using a free calculator from Iowa Beef Center that provides helpful information. Masters Choice hybrids are well known as industry leaders in corn silage, but the hybrids have great versatility. The expected yield should be about 105 percent of the five-year yield average. Hybrids still need to be able to handle stressful environments, adapt to multiple soil types and out-yield the competition. However, you can mow whatever grass is on your land, so you do not need to use up a field to do this on the side. Our leading products are protected by traits and technologies to maximize the genetic and yield potential of your Pioneer® brand seed. A variety of approaches to price corn silage based on corn grain prices end with a similar range of values. Maximizing Corn Silage Yield and Quality Greg W. Roth Associate Professor Department of Crop and Soil Sciences Penn State 2003 4 State Forage Conference. To calculate the moisture content, subtract the dry matter content from 100. Corn Silage Quality Ranking Metrics • Model based approach • Predicting milk yield based on overall diet. 2. University of Nebraska–Lincoln research has shown that corn silage priced standing in the field before harvest should be at valued at 7.65 x the price per bushel of corn where a ton of corn silage is harvested at 60-65% moisture. Adjust Your Yield. Corn Silage. At Masters Choice we tend to lean towards lower, more moderate populations than the industry has been heading. Bruce Anderson, forage specialist from the University of Nebraska, offers up a simple approach to consider. of gluten feed (20% protein), 2.5 lbs. We have provided a form that will allow you to put in some numbers and it will calculate your estimated corn yield. Because it can be used at a relatively early stage of kernel development, the Yield Component Method may be of greater assistance to farmers trying to make a decision about whether to harvest their corn for grain or silage. x 7.65 = $26.78 per ton in the field. Once your new values are entered, re-click or tap “Calculate Savings” to see your personalized savings and bottom line results. The old thumb rules for pricing corn silage are still used extensively: For fermented, shrunk and stored corn silage, multiply the price of corn by a factor of 10 to get a price per wet ton. Lower yield potential should be expected with BMR corn, and a dairy with limited acres available to produce corn silage may be required to purchase additional silage from other producers. This is shown below: 1 bushel of corn: When drought causes yield reduction of 20 to 40 percent below normal, the silage produced appears to be equal to much higher yielding corn, but tons per acre are reduced proportionally.

But with corn for silage you can’t stop there. Multiply average grain moisture by 1.411. starch ÷ 0.72 ÷ 0.845 Repeat for 5 to 7 representative areas in the field 7. starch Grain yield spaci = lbs starch ÷ (% starch content) ÷ (DM % of shell corn/56 lb./bu) sdai (example) aidf = 5,775 lb. Corn should be in full dent and the stalks should still be green. Hybrids planted for silage should be about 5 units greater in relative maturity than hybrids planted for grain. Dr. Bill Weiss at Ohio State indicates that immature corn silage is worth about 85% of the economic value of normal corn silage – if it is the same dry matter content. Heat the sample again on high for 1 minute. This is the largest variable you have control over. Estimated yield would be [(24 x 0.5) / ((1.411 x 30) + 46.2)] x 1,000, which equals 135 bu/acre. Change in output for a 20% increase in various hybrid inputs for a 500-cow dairy farm feeding corn silage as two-thirds of total forage. For example, if corn is priced at $2.00 per bushel and grain yields were determined to be 150 bushels per acre then corn silage at 65% moisture would contain 7.4 bushels of grain per ton of corn silage. Based on this information, we can calculate the actual yield to the theoretical yield and determine the percent yield we can achieve for ethanol conversion. Weight corn harvested. The yield drag can increase to 10 to 20% if the wrong relative maturity or wrong product is selected when compared to non-BMR corn products.
