Glossary
The terms the brief uses, defined the way the feed trade says them.
- DDGS (Distillers Dried Grains with Solubles)
- The corn that is left after an ethanol plant ferments off the starch, dried for shipping and shelf life. It is a mid-protein, high-energy feedstuff, roughly 29 to 30 percent crude protein on a dry-matter basis, fed widely to dairy, feedlot and hog rations. It is this wire's headline ingredient.
- Solubles
- The syrup fraction of the distillers stream (the dissolved and fine-suspended material) that is added back onto the grains before drying. Grains WITH solubles are DDGS; the solubles are why DDGS carries more energy than distillers grains alone.
- WDGS (Wet Distillers Grains with Solubles)
- The same distillers co-product sold wet, around 30 to 35 percent dry matter, straight from the plant. It is cheaper per ton but mostly water, so it only pays inside a short haul radius. This wire prices it but does not score it on the leaderboard, because its wet dry-matter basis is not the verified dry coefficient.
- Crude protein (CP)
- The protein content of a feed, measured as nitrogen times 6.25, expressed as a percent of dry matter here. Crude protein is the axis the leaderboard ranks the protein feeds on: cost per pound of crude protein.
- TDN (Total Digestible Nutrients)
- The standard energy measure for beef and growing cattle, a percent of dry matter that sums the digestible energy fractions. Higher TDN is more energy per pound. The leaderboard ranks energy feeds on cost per pound of TDN.
- Net energy for lactation (NEl)
- The dairy energy metric, in megacalories per pound of dry matter, the energy a lactating cow actually captures. Where a primary source publishes it, this site shows a cost per megacalorie of NEl alongside the TDN read. Some feedstuffs carry no NRC-published NEl, so they are ranked on TDN only.
- Dry-matter basis
- Comparing feeds after their water is removed. A ration is balanced on dry matter, so the leaderboard converts every as-fed board price to a cost per ton of dry matter first. This is why a cheap wet feed is not automatically a cheap fed feed: you pay for the water once and it carries no nutrient.
- FOB plant vs delivered
- Where a price is quoted. FOB plant is at the plant gate, before freight. Delivered is at the mill or farm, freight in. The same ton of feed carries a higher delivered price the further it hauls, so this site labels every price with its basis and never compares an FOB quote to a delivered one as if they were the same number.
- Basis
- In the feedstuffs reports, basis has two meanings. It is the FOB-versus-delivered freight point above. It is also, on some lines, a price quoted as cents over or under a futures month rather than a flat number; USDA resolves those to a dollar range, which is what this site stores.
- Corn + soybean-meal benchmark
- The two commodities every feedstuff is priced against: corn as the energy anchor, soybean meal as the protein anchor. A nutritionist asks whether a feedstuff beats corn on cost per unit of energy or soybean meal on cost per unit of protein. That comparison is the leaderboard.
- Substitution leaderboard
- This site's flagship. Every feedstuff ranked by its cost per pound of protein and per pound of energy on a dry-matter basis, against corn and soybean meal. A feed under 100 percent of soybean meal on protein, or under 100 percent of corn on energy, is delivering that nutrient cheaper than the benchmark this week.
- Feedstuffs report
- The USDA Agricultural Marketing Service weekly reports this wire reads: the Grain and Oilseed Processor Feedstuff report, the Mill-Feeds and Miscellaneous Feedstuff report, the Animal By-Product Feedstuff report, and the Grain Co-Products report. Together they price the feedstuffs by region and basis.
- Corn gluten feed vs meal
- Two different corn-milling feedstuffs. Gluten FEED is the bran and steep, mid-protein and mid-energy. Gluten MEAL is the concentrated protein fraction, around 60 percent crude protein and priced far higher. They are not interchangeable and this site keys them separately.
