Soybean hulls price

Soybean hulls is a fiber source, fed for effective fiber and gut fill more than for nutrients. On a dry-matter basis it runs about 12.4% crude protein and 77% TDN, roughly 0.78 Mcal of net energy for lactation per pound of dry matter, at about 90% dry matter as fed. Those figures come from University of Arkansas Cooperative Extension, Composition of Selected Livestock Feeds (FSA3043), from NRC Beef Cattle 1996 + Dairy One. TDN spans 62.6% (NASEM Beef 2016) to ~80% (NRC Beef 1996); 77 is the higher-history midpoint. The leaderboard uses them to convert this week's board price into a cost per pound of protein and per pound of energy, so it can be ranked against corn and soybean meal. Prices are quoted per ton, and the cheapest board price is not the cheapest fed price once freight and moisture are counted (see the FOB-vs-delivered guide).
