Última Not All DDGS Are Created Equal: Nutrient-Profile-Based Pricing to Incentivize Quality AgEcon Fabiosa, Jacinto F.. This study finds that distillers dried grains with solubles (DDGS) is a dominant feed ingredient in hog finishing rations, despite variability in the product’s nutritional content. The optimal inclusion rate has remained at the maximum allowable limit of 20%, suggesting that when a particular DDGS product has low nutrient content, feed compounders simply supplement with corn and soymeal, whatever deficits in nutrients are created as a result. The study examines DDGS products from 40 different ethanol plants and finds that, relative to the DDGS product with the lowest feed ration cost, the optimal feed ration costs of DDGS products from the other 39 ethanol plants are $0.002 to $0.42 more per cwt of feed. The implied price discount from this cost...

Ano: 2008 URL: http://purl.umn.edu/44755 Land-Use Credits to Corn Ethanol: Accounting for Distillers Dried Grains with Solubles as a Feed Substitute in Swine Rations AgEcon Fabiosa, Jacinto F.. Many studies on the impact of biofuels on greenhouse gas emissions do not consider indirect land-use change and land use avoided because of co-products utilization. This paper provides estimates of the land-use credit for corn ethanol when its by-product—distillers dried grains with solubles (DDGS)—is used in swine feed rations to substitute for corn and soymeal. The range of estimates used here covers the land-use credit used in the literature. Moreover, this study departs from earlier studies because feed rations from a least-cost optimization are used rather than rations from feeding trials, and DDGS nutrient profile variability is fully accounted for. As a result, displacement rates and the land-use credit can be better characterized using a...
