Impact Of Feeding Distillers Grains Or Isolated Components In Distillers Grains To Growing And Finishing Cattle, And The Comparison Of Protein Content And In-Situ Digestibility Of Feeds Commonly Used In Feedlot Diets, Brianna B. Conroy
Department of Animal Science: Dissertations, Theses, and Student Research
The use of distillers grains originating from biofuel production has become widely used in feedlot diets. Distillers grains has been identified as having an increased feeding value relative to dry-rolled corn, in recent years the composition of distillers grains has begun to change due to greater refinement in the ethanol production process. Two feedlot trials were conducted to evaluate the contribution of fat, fiber, and protein from distillers grains in the diets of growing and finishing cattle. Growing steers were fed a grass hay-based ration, including a corn control diet compared to a diet containing modified distillers grains plus solubles, …

Finishing cattle performance and mass balance was evaluated with Micro-Aid was fed in diets containing wet distillers grains plus solubles (WDGS) at 35% (DM basis). Micro-Aid is a feed ingredient derived from a Yucca extract which contains saponins, and was included in the treatment diet at 1 g/hd daily in the supplement. There was no difference in performance and carcass characteristics between treatments. In the winter experiment, cattle fed Micro-Aid had a greater amount of OM and DM removed from the pen surface. Micro-Aid in the diet increased the amount of manure N and decreased N lossis in the winter. …
Distillers Grains With Solubles For Feedlot Cattle - Finishing Performance, Lipid Metabolism, And Ethanol Greenhouse Gas Balance, Virgil R. Bremer
Distillers Grains With Solubles For Feedlot Cattle - Finishing Performance, Lipid Metabolism, And Ethanol Greenhouse Gas Balance, Virgil R. Bremer

Previous University of Nebraska feedlot research trials have characterized the feed value of wet distillers grains plus solubles (WDGS). These trials were summarized with meta-analysis methodology and indicated the feed value of WDGS interacts with corn processing type, cattle age (calf-fed or yearling), and inclusion level. Two steer finishing studies and a metabolism study were conducted to understand the impact of different lipid sources in WDGS on WDGS feed value. A biphasic lipid extraction procedure was developed to analyze feed samples from these trials that was more effective than Goldfisch ether extraction at lipid analysis of byproduct feds. These trials …
