all over Iowa | You need to know the dry matter level of both feeds to make the comparison. Dry gluten is typically 90% DM. So, I would divide the dry gluten cost by 90% to get the 100% DM cost. Then I would multiply the 100% DM cost by the 45% DM (55% moisture) of the other feed to get the value at that moisture.
$150 divided by .9 = $166.67/ton of dry matter $166.37 x .45 = $74.87/ton.
So if you can buy the wet feed for $50 a ton it is a better buy, because it is less than $74.87/ton. This is also assuming the two feeds are the same protein and energy levels on a dry matter basis. |
