When you make all the calculations the total value of lost silage is $15,322, total cost of covering is $1,746, and the net benefit of covering equals $13,575. This provides a 7.8 to 1 return on your investment which is exactly what Kansas State University researchers have reported. So this investment returns nearly $8.00 for every $1.00 invested; plus your valuable animals are not exposed to the potential toxins in the spoiled silage. If you can find any other activity paying that kind of return, please give me a call! The bottom line is that sealing the exposed surface is one of the most cost effective management decisions in any silage program.
I have put together a simple spreadsheet model you can use to assess the cost/benefit of covering your bunker silo(s). If you would like a copy send me an e-mail requesting the “Bunker Silo Covering Model.”
