Abstract
Introduction
Two primary types of milling processes currently exist, resulting in quite different feed products. These processing plants produce and market a variety of feed products, but in general, the dry milling process produces distillers grains plus solubles (DGS), and the wet milling process produces corn gluten feed (CGF). These feeds can be marketed as wet feeds, or they can be dried and marketed as either dry corn gluten feed (DCGF) or dry distillers grains (DDG) with or without solubles.
For the purposes of this report, wet corn gluten feed (WCGF), wet distillers grains plus solubles (WDGS), DCGF and dried distillers grains plus solubles (DDGS) will be discussed. The term DGS will be used for undifferentiated discussion about WDGS and DDGS. The majority of ethanol plant expansions are dry milling plants that produce DGS; however, an increase in supply of WCGF is also expected. Therefore, these feeds may be very attractive for beef producers to use as feed sources. This report will focus on the production, composition, feeding values and economics of using these co-products in feedlot situations. Management strategies will be discussed as well, including grain processing and roughage levels when these co-products are used in feedlot diets, and the use of co-products in combinations, at high dietary inclusions, in replacement of forages in adaptation diets, and the effects of fat, fiber and sulfur with these products. Storage methods for wet products and nutrient composition and variability from co-products will also be discussed.
