Assuming 15 per cent moisture and 20 per cent baling . pounds of dry forage per cubic foot (lbs DM/ft 3). [Weight may need adjustment due to moisture or. We will assume that the value of the cob, husks, etc. Hay bale density is determined by how much the baler compresses the hay. Silage densities can easily be measured using a special silage probe and a scale. In a 5-foot by 5-foot bale, the difference between 10 and 11 pounds of dry matter per square foot amounts to over 100 pounds per bale at both the 10 and 15 percent moisture levels. Averaged over all species and cuttings, the density of forage in a wagon was 5.0 pounds of dry forage per cubic foot (lbs DM/ft³). . hay or haylage," Cole says. This Factsheet contains estimates of tower silo capacities for alfalfa silage . Summary Bunker Silo Density Calculations. Weight of silage per cubic foot increases from top to bottom in tower silos. per cubic foot (cu. A dry matter density of 10 pounds per cubic foot is considered ideal. . For example, silage in a bunker silo has a dimension of 30 by 10 by 50 feet. Boerner Cargo Precision Riffle . Figure 35 to 40 pounds of silage per cubic foot in trench silos. Corn silage in growing rations Corn silage rations usually produce larger daily gains and more pounds of gain per acre of crop for growing beef calves than sorghum or milo silage or other silage crops. 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. Bales that deform slightly when pressed or spiked will likely have 10 pounds DM or less. The goal is to achieve more than 15 lbs of dry matter per cubic foot for corn silage and haylage. Densities ranged from 6.0 to 21.7 lbs dm/ft³. Figure 1: Concrete blocks and an extra tractor are effective ways to increase packing weight and silage density. ft. or .

DM per cubic foot. is about $70 per ton of DM, approximately that of baled crop residues. To convert to bushels of corn, multiply cubic feet times .8 (If the corn is 15.5% moisture). It will take about 0.5 pounds of grain per 100 pounds of body weight per head daily in the ration for grass-legume silage or haylage to give similar rates of gain to a full feed of corn silage. How can the total weight of a loaded forage box . After the last load is delivered and packed, get off the pile, as additional time spent on the pile will not improve density. determine the dry matter intake of that feed. Previous How much space does a cow need in a shed that allows them to go in and out? In Imperial or US customary measurement system, the density is equal to 114 pound per cubic foot [lb/ft³], or 1.055 ounce per cubic inch [oz/inch³] . The blended hay/silage feed mixture is input to the compression apparatus at a density of approximately 16.6 pounds per cubic foot and compressed to a density of 30-45 pounds per cubic foot, preferably about 40 pounds per cubic foot. Brian Holmes and Richard Muck, University of Wisconsin researchers, are encouraging the evaluation of density on the basis of as-fed weight per cubic foot of silage. . 8 Table 5 - Volume Adjustments for Wet Corn Bushels/Cubic Feet Moisture Content Shelled Corn X Ground Ear Corn X 15.5 .800 .515 16 .794 .510 17 .787 .508 How many cubic feet of hay are in a round bale 3.9 feet wide and 4 feet in diameter? Options for adding weight to a packing tractor include putting . the average body weight of the group of animals; the time frame in days that inventory needs to last; Another factor that comes into play is the forage dry matter intake, as a percent of body weight. 1 cubic yard of dirt weighs about 1944 pounds or 0.97 US tons. 7 This volume should be adequate for many rations that INCLUDE up to 20% (by weight) dry hay. A good rule of thumb is to add 3.5 gallons of water per ton of corn for each percentage point the corn is below 27 percent moisture. Calculate the Volume of a Pile in Cubic Yards. DM per cu. Grass forages were less dense and averaged 4.6 lbs DM/ft³. A 4 ft wide x 5 ft high round legume hay bale may weigh 1,000 lbs. A typical silage bale (4 feet in diameter by 5 feet in length) should weigh 1,300 to . DM per cubic foot.

Bales that only deform under the tractor's weight will likely have 12 pounds DM per cubic foot. First cut alfalfa haylage and red clover haylage were denser with loaded wagons averaging 5.6 lbs DM/ft3. Tons of wet silage or haylage = tons of dry matter / (1 - % moisture) Density = 0.8 bushels per cubic foot for corn or soybeans Density = 0.515 bushels per cubic foot for ground ear corn Density = 8.0 + (0.15 x depth of silage) (in feet) = tons of dry matter per cubic foot for corn silage (density increases with the depth of the silage) In a bunker or pile we want to achieve 18 lbs.+ of dry matter per cubic foot. Weight down the plastic cover to provide a tight seal so that all air is excluded. 1.41. Pack in thin layers of no more than 15 cm (6 inches) in order to get good air exclusion and high silage density. The capacity of a tower silo depends on: (a) the compressibility of the stored material; (b) the total volume of the silo; (c) the friction between the wall of the silo and the material; and (d) the ratio of the settled depth of silage to the diameter of the silo. A recent report from Kansas showed that buyers were paying $1 per relative feed value (RFV) point in alfalfa hay. . Table 1. Earlage is higher in energy than corn silage with similar protein content, but it has lower energy than dry or high-moisture corn grain (Table 1). For my current flock size (24 sheep) that would be 72 to 108# haylage or silage per day, lets say average of 90#. A typical silage bale ( 4 feet in diameter by 5 feet in 29 . Gallons = length x width x height (all in feet) x 7.5 gallons per cubic foot Weight = gallons x pounds per gallon Weight = 8.33 pounds per gallon for water Weight = 7.15 . with the Kansas apparatus gave an average of 33.1 pounds per cubic foot. In the last stage of compression, shown as step 120, the compressed feed product is compacted into a watertight bag. Pack, pack, pack and pack!!! Earlage is ensiled corn grain, cobs and, in some cases, husks and a portion of the stalk (depends on the harvest method). The general rule of thumb is tractor weight divided by 800 equals wet tons per hour. 4 Capacity based on 42 lbs. Bales that deform slightly when pressed or spiked will likely have 10 pounds DM or less. hay or haylage," Cole says. per ton of wet silage is equal to 18 divided by the tractor weight (tons). Sufficient tractor weight and packing time is critical. We can do this by matching packing tractor capacity and number of tractors with the tonnage of silage being delivered in. The average feed storage density in bunkers for haylage is between 12 to 15 pounds of dry matter per cubic foot, so our goal is always to be better than our density from the previous year. Bale density is measured in pounds per cubic foot. From this table, we can highlight some key weights of cubic yards of materials. It is possible to make high-quality silage or haylage using long (unchopped) forage crops baled with large round balers, although balers may need modification to handle wet material. He explains that a higher density is usually obtained with haylage, whereas the packing density for corn silage is usually a little lighter. The storage capacity of the bag system is estimated at 1.2 tons of wet silage per linear foot (10 ft diameter bag), 1 ton per linear foot (9 ft diameter bag), and 0.8 ton per linear foot (8 foot diameter bag) when forage is ensiled at . range will weigh about twice what the same size bale of hay would weigh.
