Pages: The pounds of silage in the silo is calculated by multiplying: Length (ft) x width (ft) x depth (ft) x density (lb/cu-ft) at the final moisture content. For example the silo is 50 feet long by 30 feet wide and the silage averages 12 feet deep.

50 (ft) x 30 (ft) x 12 (ft) = 18, cubic f cubic feet x 40 lb/cubic feet =lb silage. 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 silage should have a light, pleasant smell with only a slight vinegar odor.

It should be slightly brown to dark green. If it is dark brown or has an odor that is fruity, yeasty, burnt or rancid (butyric acid. Dry matter density for silage in bunker silos is quite consistent ranging from to kg/m 3 ( to Ib/ft 3) for cereal and grass silages respectively.

Dry matter density is used to calculate silo size because it is independent of moisture content within a range of 50 to 70%.

An example would be a field that yielded 25 ton of 65% moisture forage. A forage test indicates the silage contains 33% starch. The dry matter yield of starch is: DM starch yield = as fed silage yield × % dry matter × % starch (DM basis) adiii (example) idiiii = 25 ton × 2, lb./ton × (1-moisture) × We frequently get questions about the amount of silage in a silo bag.

One way to estimate this value is to calculate the volume in the bag and multiply by its density. The volume of a round bag is calculated as: V = × (D 2 ÷ 4) × L. Where: V = Volume (ft 3) spacespacii D. To estimate the settled depth of silage, multiply the selected wall height by Settled Depth (ft) = Wall Height (ft) x If the bunker wall height in our example is 10 feet, the settled depth is: Settled Depth = 10 x = ft Finally, decide what the face removal rate will be.

Density Score Card. Earlier investigations have recommended that a bunker silo dry matter density goal should be a minimum of 14 lbs dm/ft³. Of the 22 bunkers sampled in only seven (7), 32%, achieved a silage density greater than 14 lbs dm/ft3 and eight (8), 36% averaged less than 12 lbs dm/ft³.

Then estimating a bushel corn grain yield at $ per bushel or a 23 tons per acre corn silage yield at 35% dry matter, the average of minimum price and maximum price is $ per ton of silage. This is times the corn price as unharvested or $ per ton of silage which is times the corn price or as a harvested crop.

We fill our heifer silage silo and move the blower to the home farm to put some there too. I show some footage of the forage harvester. The next morning we l. There are also some rule of thumb calculations that can be used: One estimate of silage yield for corn plants without ears or poorly pollinated ears is 1 ton of dry matter (30%) for each foot of plant height.

This does not include the tassel. Corn that is 4 feet high would yield about 4 tons of 30% dry. The storage capacity of the bag system is estimated at tons of wet silage per linear foot (10 ft diameter bag), 1 ton per linear foot (9 ft diameter bag), and ton per linear foot (8 foot diameter bag) when forage is ensiled at 40% dry matter.

Therefore, compute the weight remaining as follows: Example 1. Use the table to find the original contents before the silo was opened.

50’ of settled silage in a 20’ silo weight T. Estimate depth of silage removed and determine in weight from table. Weight removed in 32’= Tons 3. Silage, also called ensilage, forage plants such as corn (maize), legumes, and grasses that have been chopped and stored in tower silos, pits, or trenches for use as animal protein content decreases and fibre content increases as the crop matures, forage, like hay, should be harvested in early green material should be chopped fine enough to assure good packing and the.

This Factsheet contains estimates of tower silo capacities for alfalfa silage, whole-plant corn silage and various types of high moisture corn based on a series of analyses of silo capacity carried out at the University of Guelph and on research done at research establishments in the Netherlands and Sweden.

Cut-ting the silage into 3/8 to 1/2-inch pieces will help packing. Removing as much oxygen as possible will decrease the time needed to. If corn is unusually dry and has little grain, deduct 15 per cent. If the silo is filled rapidly and no time allowed for settling, deduct 10 per cent.

ESTIMATING THE WEIGHT OF SETTLED SILAGE When silage has been In the silo for one month or more, use Table 2 for estimating the weight. While the materials in the 25 to 30 percent dry TABLE 2 Density of corn silage as affected by the amount of pressure applied and by stage of growth of crop Growth Av.

Mature, high-yielding grain corn should contain 50 percent grain by dry-matter weight.

The above example is typical of good-quality mature corn made into silage. (d) A variety of corn adapted for silage use only, when the corn is reported for insurance as grain, e.g., TMF (Totally Managed Feedstuffs) corn, etc.

(4) Any acreage of the insured crop damaged before the final planting date, to the extent that. 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.

For a crop of corn silage still standing in the field, multiply the price of corn. The yield estimate determined will only be a guide and assumptions made from the estimates contain a degree of uncertainty. This type of yield estimation is one of the easiest and quickest to complete and should be able to be used in a number of situations on a grain growing property.

Grain losses both before and during harvest can be. silage. Silage that is too dry may result in poorly packed material, causing more mold and spoilage due to air trapped in the silage. In dry, over mature corn silage, the stover portion of the plant is less digestible and contains lower amounts of sugars and vitamin A.

It will not pack well in the silo, more. Silage from 10 ft. silo Corn Soybean (11) pounds pounds 'Values at the greater depths were influenced by gravitational moisture. Sorghum and kafir silages did not differ widely from corn silage. Depth in silo. The importance of harvest moisture and maturity to corn silage quality and animal performance is often underestimated.

Not only is it important to minimize fermentation dry matter and spoilage losses, it is difficult to compensate for poor forage quality in ration balancing and animal performance.

Don't get caught harvesting corn silage past optimum moisture and maturity. the silo capacity has been estimated to decrease by about 25%. The maximum capacity of a tower silo filled with corn silage is achieved when the moisture is between 60 and 65%.

Managing the Moisture Content of Silage The best way to manage moisture content of corn silage is to harvest at the proper stage of plant development. Despite an unusually wet spring followed by an unusually cool June, America’s corn farmers planted even more than they did last year. U.S.

farmers have planted million acres of corn inaccording to the National Agricultural Statistics Service (NASS). That’s about 69 million football fields of corn and 3 percent more corn than last year, far more acres than the next largest crop. If the silo is filled but once and is not refilled after the silage has settled, not more than two-thirds the capacity of the silo can be obtained in settled silage.

Thus if the silo can be filled in the manner first mentioned one should be constructed which has a maximum capacity one-third greater than for the amount of silage : Cornell University. Station. Producing high-quality forage as silage, while avoiding DM losses as much as possible, is a challenge.

The silage-making process is commonly divided in 4 phases: (1) the initial aerobic phase in the silo immediately after harvest, (2) the fermentation phase, (3) the stable storage phase in the silo, and (4) the feed-out phase when the silo feed face is open and the material is exposed to air.

Given a corn price of $/bu., these factors would result in silage being priced at $ to $ per ton. I prefer to use a method that is more complicated but takes into account moisture content of the silage in addition to the price of corn grain.

First, the method assumes that the dry matter of whole plant corn silage contains 50% grain. In today's video we chop the last loads of silage, fill the silo to the brim & level out silage at the top of the silo. To better understand and predict silage density in bunker silos, chopped whole-plant corn was placed in layers of,and m in a x mm rectangular container simulating.

NOTE: When a silo is partially unloaded from the top, the remaining silage is more tightly packed and heavier than the same volume in an unopened silo. Therefore, compute the weight remaining as follows: 1. Use the table to find the original contents before the silo was opened.

(Example: 50' of settled silage in a 20' silo = tons). Removing the chute doors on the silo down to the level of the settled silage will permit natural ventilation where gas tends to be concentrated. Keep the doors between the silo room and the barn closed to protect livestock.

Length of cut Corn silage should be cut into particles 1/2 to 3/4 inches in length. Yield Input” spreadsheet will provide an estimate of corn silage yields and value. Besides knowing the yields of either corn grain or silage, the dry matter of the silage should be.

determined. Recommended dry matter (DM) for corn silage ranges from percent DM for bunkers and bagged silage, and percent DM for silos. universityofillinois agriculturalexperimentstation bulletinno cropsforthesilo,costoffilling, andeffectofsilageonthe flavorofmilk.

urbana. However silage cut at this greater height has been shown to have 8 to 15 percent less silage yield and 2 to 12 percent less milk per acre. So, the lower tonnage with high-chop silage is seldom justified in the absence of high nitrate levels. When harvest begins, fill silos rapidly to reduce exposure of silage to oxygen and to reduce fungal growth.

The Corn Silage Crop Calculator is a Microsoft Excel-based program that comes in two parts. One part calculates silage price based on silage yield from the field, while the other calculates silage price based on corn grain price.

Either part can be used to arrive at a price for corn silage.Capacity of the Silo.-The capacity of the silo should depend on the needs of the farmer.

A cubic foot of silage under average conditions will weigh 35 to 40 pounds. Ordinarily, this amount is enough, with other food, for a day's feeding for one cow.

A beef animal should not be fed quite so heavily as a dairy cow, and 50 pounds is ample for a.
