Our estimates and projections are subject to all the variable factors that impact livestock markets and weight gain, which may be different for your circumstances. Before doing the calculation please read the following. Silage piles normally do not have straight sides or ends, so compared to other storage methods, piles are the most difficult to measure when calculating inventory. estimated by the following equation: Feed Value Lost ($) = Bunker Capacity (total ton DM) x Difference in Estimated Losses SKU: ff-bcvr-001. This maximum height of silage is assumed to be midway between each wall. The feed value lost as a result of not covering the silage can be Also assume, for this the feed recovery from a bunker silo.

If you have an existing bunker silo use this calculator to determine how much silage you have on hand. Wheat variety performance test by various testing methods and data interpretation. Silage moisture content and density Silage density is proportional to moisture content; the dryer the silage, the lower its density. (fraction of % loss) x Value of Silage ($/ton DM), Feed Value Lost = 196 tons DM x 0.15 fraction loss x $40/ton DM = $1176. It is avg. Remember, you should remove at least six inches per day. For example, assume 3,000 lbs. 50 (ft) x 30 (ft) x 12 (ft) = 18,000 cubic feet 18,000 cubic feet x 40 lb/cubic feet = 720,000 lb silage 720,000 lb of silage / 2000 lb/ton = 360 tons of silage in this silo.
