haylage weight per cubic foot
Other important aspects of proper packing are the weight of packing tractors and the amount of time devoted to packing. 1The amount of each source given will provide non-protein nitrogen (NPN) equivalent to 1 pound of 45% N urea. A fifth phase may occur if improper silage production practices cause undesirable or abnormal silage fermentation. Follow the manufacturer's recommendations for refrigeration or freezing. All rights reserved. This increases the level of bound protein and ADF in the silage. Check plastic covers every two weeks during storage and immediately patch any holes. Ammonia also is not corrosive to most metal equipment. Foul-smelling silage usually contains high levels of butyric acid, but a variety of other compounds add to this odor. As has been well documented by research, storage losses can range from below 5 percent to over 50 percent, depending on storage method. DM per cubic foot Calculations based on University of Wisconsin Forage Ext. However, if the sample has normal moisture content and is well-sealed, it can be sent within 2 days. Missing the weight of a bale by 10 percent amounts to some pretty significant dollars if multiple tons are being purchased. This is because legumes such as alfalfa will make a denser bale than a grass species. Care should be used when interpreting the results of a shrink calculation. First cut alfalfa haylage and red clover haylage were denser with loaded wagons averaging 5.6 lbs DM/ft3. This phase of the fermentation process continues for one to two days and merges into phase 3. During browning, proteins combine with plant sugars to form a brown lignin-like compound. Note the considerable variation due to crop and dry matter content differences. For dairy-quality silage, consider harvesting alfalfa in the bud to early bloom stage and grasses in the boot stage. These testers can take several readings over a short period of time, but typically they must be calibrated or measurements must be converted. Commonly used non-protein nitrogen additives for corn silage. These thin layers are crucial to properly pack the silo. Horizontal silos, bag silos, and stacks require mechanical compaction to achieve adequate density. Two factors dictate the amount of sugar required for maximum fermentation: water and crop species. No.
Density = 0.628 bushels per cubic foot for ear corn To keep silage fresh in the feed bunk, remove uneaten feed, clean the bunk daily, and keep water out. Table 12. Mold prefers moisture levels greater than 12 percent, temperatures above 23F, at least 0.5 percent oxygen, and moderate pH. Grass forages were less dense and averaged 4.6 lbs DM/ft 3. Recommended removal rates are presented in Table 18.
Minimize the exposed surface area by removing silage evenly from the entire face to form a smooth, vertical surface that is perpendicular to the silo sides and floor. Moisture content of the forage plays an important role in the extent of fermentation, due to variation in bacterial populations and the buffering capacity of water. Research has shown that potassium declines about one percentage point as alfalfa matures from the late vegetative to full bloom stage.
Oxygen can penetrate several yards into a loosely packed silage mass, but dense forage limits the rate of oxygen infiltration. The amount of mycotoxin consumed, the specific toxins present, and each animal's level of tolerance influence the severity of toxic effects. Another factor in the success of microbial inoculants is plant sugar content. Another method gaining popularity is the silage facer, usually a rotating drum covered with blades.

Consult your dairy nutritionist when you suspect problems related to mycotoxins. Weight per cu. Table 1. If sorghum forage is stunted by frost, delay harvest until 4 days after a killing frost or ensile the material. In addition, crop species greatly influences the buffering capacity and carbohydrate level of plants before ensiling. When storing silage in upright silos or bags, inoculation at the blower or bagger is also acceptable. Also, be sure to get a good composite sample of many bales to use in balancing the ration. In concrete silos, cover the silage surface with 4 to 6 mil plastic and weight it with at least 12 inches of wet forage. These organisms also consume digestible nutrients and produce heat. Characteristics of silage that has undergone clostridial fermentation include pH above 5, high ammonia-nitrogen levels, more butyric acid than lactic acid, and a strong, unpleasant odor. 4Source: Dairy One Forage Lab. Measuring alfalfa or corn silage yield is necessary to adjust management practices, to maintain crop inventories, and for crop reporting purposes. Silage: Field to Feedbunk. Table 4. It is important to determine the fill height for each load so that the correct volume is computed. WebSince this was already after dark, after 9 p.m. we were glad to get it done! Preservatives may be useful where forages have short bunk life or when the crop is ensiled at less than 60 percent moisture.
This situation has led to the development of a custom operations industry in many areas. WebTypical hay bale density is 9 to 12 lbs per cubic foot. High-level management and sizeable financial outlays are necessary to efficiently produce, harvest, store, and feed silage. Frosted immature plants appear drier than unaffected corn of the same moisture content. To reduce the risk of rolling the packing tractor, avoid backing off the silage pile; instead, back onto the pile and drive forward off it. Provided the ensiled forage contains an adequate supply of readily available carbohydrates, fermentation in the silo will not progress to phase 5 when proper production practices are followed. Ft. will vary by amount of packing, fineness of cut, Moisture content, and depth of material. Source: Pennsylvania Agricultural Statistics Service. In addition, this example will assume an average forage density of 5.0 lbs DM/ft and a forage dry matter of 40%. Some silos that look fine may actually be ready to collapse. It's not an everyday problem, but there will be times when you need to calculate the capacity of something. It frequently is used to refer to the loss of feed during harvest, handling, and storage. In extremely wet seasons, flooding increases the number of yeasts, molds, and aerobic bacteria in the crop. Haylage varies due to the type and use of machinery, sward type and density, and, most of all, the dry matter of the crop harvested. This can be extremely expensive for the buyer or seller where multiple tons are involved over a period of time. Since all exposed surfaces of the silage mass allow oxygen to enter, spoilage happens during both storage and feedout. The earliest sign of possible toxicity is discoloration of mucous membranes in the vagina, mouth, or eyes. These compounds raise silage pH. Recommended ranges exist for individual forages, but the real value of the particle size measurement is combining forages to achieve the proper TMR particle size, which is much like combining feeds to achieve the proper protein level. High levels are often found in legume haylage because it contains more protein (greater buffering capacity) than corn silage. Wet weather tends to increase fiber levels and decrease protein content in alfalfa. Haylage can be safely fed to cattle, sheep, and goats. Immediately after filling the silo, manually level the surface and walk over the silage until it is tightly packed. trailer << /Size 234 /Info 169 0 R /Encrypt 187 0 R /Root 186 0 R /Prev 235248 /ID[<03c3f8c75692ed62b9f40aeef95d39f5>] >> startxref 0 %%EOF 186 0 obj << /Type /Catalog /Pages 172 0 R /Metadata 170 0 R /JT 184 0 R /PageLabels 168 0 R >> endobj 187 0 obj << /Filter /Standard /R 2 /O ( UV.`Dz-#_m_}g) /U (]pek+YTCYm{`N) /P -4 /V 1 /Length 40 >> endobj 232 0 obj << /S 607 /T 728 /L 800 /Filter /FlateDecode /Length 233 0 R >> stream Figure 10 was developed from alfalfa silage inoculation trials in Wisconsin and New York. DM per cubic foot 4 Capacity based on 42 lbs. Since sugars are the primary food for lactic acid bacteria, low sugar levels can limit bacterial activity and reduce the effectiveness of the inoculant. A caramelized or cooked odor, similar to tobacco or burnt sugar, is also abnormal. In addition, rapid harvest ensures that the majority of forage is at the correct moisture and maturity. The presence of visible mold does not mean mycotoxins are present, and mycotoxins may exist when mold is not visible. Weight = 7.15 pounds per gallon for diesel fuel (at room temperature) 260 Heady Hall Horizontal silos, bag silos, and stacks require mechanical compaction to achieve adequate density. This phase involves the production of butyric acid and other undesirable products, such as ammonia and small proteins called amines. Break-even curves for using bacterial inoculants in alfalfa silage wilted from 1 to 3 days, assuming inoculant costs $1/ton as fed and will result in a return of $3/ton. Typically, used tires are placed close together on the plastic and the edges are weighted with sandbags or soil. Replace any worn gears, belts, chains, bushings, and sprockets, and order replacement or spare parts. Grass forages were less dense and averaged 4.6 lbs DM/ft. Always avoid lifting from the bottom of the silage mass, which creates cracks that allow air to penetrate deep into the silage. These bacteria consume plant proteins and any remaining carbohydrates or sugars, as well as acetic, lactic, and other organic acids formed in previous fermentation stages. Properly fermented silage has butyric acid levels near zero.

When corn for silage contains more than 70 percent moisture, delay harvest until frosting, freezing, or advancing maturity lowers its moisture content. In vertical silos, bulk density is close to 20 pounds per cubic foot (lb/ft 3) at the top and 60 lb/ft 3 or more near the base. Sometimes growers sell hay from a field and require an estimate of the quantity removed or sold. Prevention and Control of Nitrate Toxicity in Cattle. Proper agronomic practices and fermentation in the silo can prevent mycotoxin production. Properly adjusting the number of knives and the feed roll to cutter head speed ratio improves the quality and accuracy of the cut and avoids tearing forage. Keep in mind that harvest time is the only opportunity to make forage particles longer. Storage facilities with an exposed silage surface must be sized to match the feeding rate to prevent spoilage. In wet forage, a lower pH is needed to prevent undesirable bacteria growth. 185 0 obj

The increased acidity also helps to limit the growth of undesirable organisms as silage ferments. In addition, other non-protein nitrogen compounds (NPN) are created from plant proteins, and some, such as putrescine and cadaverine, have particularly unpleasant odors. Research at The University of Wisconsin and Cornell identified a significant advantage for bunker silos with a density pack greater than 14 pounds of dry matter per cubic foot of silage. Density = 0.515 bushels per cubic foot for ground ear corn Legumes have a natural buffering capacity and require more acid to reach a low pH than grasses or corn. Long distance transport of round bales presents some special problems. Long distance transport of round bales presents some special problems. Weighing bales might not be as convenient as not weighing them, but there are very few situations where its not an option. Storing ammoniated silage in zinc-coated steel silos is not recommended because ammonia is highly corrosive to zinc, copper, and brass. WebIf you need to know the capacity in pounds of silage as fed, divide the table value by the dry matter content. Once wrapped, bales can be stored on end and stacked up to three layers high to increase density (very wet bales should not be stacked). Check the cutterbar surface to be sure it is sharpened, not rounded. Changes in nutrient composition of corn silage with advancing maturity. Webpounds of dry forage per cubic foot (lbs DM/ft 3). Excessive oxygen trapped in the forage mass will cause initial temperatures to rise well above 100F and limit lactic acid production. In this case, the ammonia acts as a buffer and allows more of the acids to build up in the silage. This phase begins as the supply of oxygen is depleted, and anaerobic bacteria that grow without oxygen begin to multiply. The forage used for haylage is cut the same as it would be for will for dry hay, the difference is in the timing of baleing. This loss can be reduced to 10 20 percent by using a simple ring feeder. These numbers will vary slightly depending on the moisture content and length of cut at harvest. Carbon dioxide build up in the silo also may occur during the respiration phase; inhaling concentrated carbon dioxide can cause asphyxiation. Progress Rpt. Microbial inoculants may benefit drought-stressed forages because normal bacteria populations tend to be low; these are best used when moisture content is normal or high. When purchasing baleage, it is always recommended to either weigh the bales or have a rock-solid moisture test. When selecting a microbial inoculant product, look for one or more of these lactic acid bacteria: Lactobacillus plantarum (or other Lactobacillus species), Pediococcus species, or Enterococcus (Streptococcus) species. Soybeans also can be made into round bale silage. Chop length for silage affects compaction and fermentation in the silo and roughage value and rumen function in the cow. Forage additives should be used as tools to improve silage management, not as a substitute for poor management. To reduce nitrate levels in drought-stressed plants, harvest crops in the afternoon on a warm, sunny day; be sure to wait 3 to 5 days after an appreciable rain or long cloudy spell. The recommended theoretical length of cut (TLC) is 3/8 to 3/4 of an inch for corn silage and 3/8 to 1/2 of an inch for alfalfa silage. These products usually contain a combination of acids, including benzoic, sorbic, acetic, or citric acids, but propionic acid typically is the primary ingredient due to its excellent ability to inhibit the growth of yeast and molds. Legume forages have greater buffering capacity than corn silage due to their high protein and mineral content, which means it takes more acid to lower the pH of legume silage. Clostridia are spore-forming bacteria that normally live in manure and soil and can grow in silage when oxygen is absent. Dry matter recovery was improved at greater depths, but losses still exceeded 25 percent. Both alfalfa and grass usually provide more energy and protein when harvested as silage than as hay. Once the crop is cut, storage, mixing, and feeding can only reduce particle size. Table 20. Web1 Capacity based on 16 lbs. 3Sorghum-sudangrass hybrid. WebTypical hay bale density is 9 to 12 lbs per cubic foot. These processes consume readily available carbohydrates stored in the plant and produce carbon dioxide, water, and heat. Research has shown variable effects and a degree of specificity that is not completely understood. Table 8. How Moisture Content Affects Hay Bale Weight Fresh baled hay: 18% to 20% moisture by weight. Plastic covers must be weighted to prevent air infiltration under the plastic. Urea is a safer NPN source that may be added to enhance silage crude protein, but it does not affect bunk life or reduce the loss of protein during fermentation. In some cases, byproducts of clostridial fermentation also affect the normal rumen microbial population and create additional feed intake depression due to reduced feed digestibility. Recommended methods of removing material from bunker silos or piles with a front-end loader include scraping from the top down, or, if space permits, shearing from side to side. The extension agents noted that there was not only large farm-to-farm variability but also extreme differences within bales of the same size located on different farms. For many years, I helped coordinate a monthly quality-tested hay auction where sellers had the option of selling by the bale or by weight from a certified scale. 0000015041 00000 n A quick inspection may save lives and thousands of dollars in lost feed and damaged property. Figure 7. In addition, if one stored forage contains over 1,000 ppm NO3-N, all forage and water sources should be tested to determine totalNO3-N intake. Patch any cracks or holes to keep the walls, floor, and roof air- and water-tight. Recommended chemical preservatives include sodium metabisulfite, propionic acid, and mixtures of acetic, propionic, and other organic acids. Alternatively, organic acids may be used at the rate of 10 to 20 pounds per ton to aid in preservation. Research at The University of Wisconsin and Cornell identified a significant advantage for bunker silos with a density pack greater than 14 pounds of dry matter per cubic foot of silage. The third phase of the fermentation process begins as the acetic acid-producing bacteria begin to decline in numbers. Density = 10 to 12 pounds per cubic foot for hay Tons of dry matter = 0.000393 x diameter x diameter x average depth of silage (all in feet) x (5.90 + (0.1 x depth)) for haylage WebAverage length x width x settled depth (all in feet) x 40 lbs 2000 lbs. Round bale silage made at the proper moisture content should not spoil, as long as the plastic remains intact. Silage acids can erode concrete or unprotected metal and can cause severe silo deterioration when seepage occurs. Keep the sample spread out thinly to promote uniform heating. Apply 7 pounds per ton on a 35 percent dry matter basis. Bale density also plays a rather large role in final bale weight. All bagged bales should be inspected regularly, and any holes in the plastic should be patched. Please enter your email address below to create account. Keep in mind that crop variation exists within the field, and in balage that variation may be concentrated into individual bales. As they mature, small grains change from vegetative growth to grain production.
Silage that is not packed has a weight of approximately 25 pounds per cubic foot, and well-packed silage is considered to weigh approximately 35 pounds per cubic foot. For cows to digest the starch in corn efficiently, the corn kernels in chopped and processed whole-plant corn must be broken into small particles. Particle size of the final crop must be within the ranges presented in Table 10, regardless of whether silage is processed. Repeat steps 7 and 8 until the sample weight does not change. Mail early in the week to avoid weekend delays. Silage and Hay Preservation. How can the total weight of a loaded forage box be estimated? Three to 8 percent of corn silage particles should be retained on the upper sieve of the separator (Table 10). For grasses, the change is about one-half of the levels found in immature forage. High levels of naturally occurring bacteria in silage make it difficult for inoculated bacteria to gain a competitive edge. Bushels = 0.314 x diameter x diameter x average depth of grain (all in feet) for ear corn, Bushels = width x length x average depth of grain (all in feet) x density (same values as previous), Bushels = Pi x diameter x diameter x depth of grain (all in feet) x density x (1 - % moisture) / .845, for number 2 shelled corn or ground ear corn Single enzymes or enzyme complexes are typically combined with microbial inoculants to formulate a silage additive. of Science and Technology
2Includes all types of forages harvested for haylage or green chop; dry hay is not included. 8 36 12 40 20 45 Feeding spoiled silage. However, once the silo is opened, the exposed face must be managed to limit the time silage is exposed to oxygen. Figure 2. Harvesting soybeans for silage can also enable earlier seeding of fall crops, such as wheat or rye. An EEO/AA employer, University of Wisconsin-Madison Division of Extension provides equal opportunities in employment and programming, including Title VI, Title IX, the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act requirements. Since this bacteria increases production of acetic acid, expect lower feed energy values and slightly higher acetic acid values in fermentation analysis. Transition Cow Management: Much More than Just Diet! In the past, silage stacks were primarily used for temporary storage. The ratio of lactic to acetic acid also may be calculated; ideally, the ratio should be 2:1 in favor of lactic acid (higher is better). Table 19. 
Also, the scale that comes with the Koster tester is not particularly accurate. Weight = gallons x pounds per gallon These factors affect the rate or extent of fermentation and the nutritional value of silage. Instead, focus on improving silage harvest and storage practices. Before each harvest, clean out all old feed and inspect the inside surfaces of each silo. Energy levels typically are within 10 to 20 percent of normal values. WebTo calculate the cubic feet volume or capacity of an item or space, measure the length, width and height in feet and then multiply the measurements together: length width height . DM per cubic foot 4 Capacity based on 42 lbs. 0000003418 00000 n
In addition, moisture levels in bales change throughout the day; bales made early in the day likely contain more moisture than those made at the end of the day. The information in this article should enable you to make more effective decisions about harvesting, managing, and feeding silage. Hay bale density is determined by how much the baler compresses the hay. These enzymes may digest readily available fiber but avoid highly indigestible fiber, which actually decreases forage digestibility. Webpounds of dry forage per cubic foot (lbs DM/ft 3). Z,5Aii:*rQVYo?n Be sure to follow the manufacturer's recommendations and ensile forage at the proper moisture content. Bushels = 0.628 x diameter x diameter x average depth of grain (all in feet) for shelled corn or soybeans Mycotoxin poisoning is less of a concern in dairy cattle than in monogastric animals, because toxins are partially degraded in the rumen. 0000011521 00000 n
Consider purchasing a small digital scale that is accurate to one-tenth of a gram. In a 1992 study, Curt Ruppel, Cornell determined that bunker silo dry matter losses approach 17 to 20% at silage densities less than 14 lbs dm/ft3. Table 24. 1Muck and Kung and Kung and Muck. Figure 6. Table 7 clearly demonstrates the changes in barley silage as it matures. Summary of common silage problems and possible causes.
