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 …

Effects Of Feeding Distillers Grains On Beef Quality, Amilton S. De Mello Jr.

This research was conducted to understand the effects of feeding finishing diets containing distillers grains on beef quality. In the first and second studies, feeding wet distillers grains plus solubles (WDGS) increased proportions of PUFA, omega 6, omega 6/omega3, and trans fatty acids when compared to corn (P ≤ 0.05). Lipid oxidation was higher in muscles from animals fed WDGS when compared to corn (P ≤ 0.05). The third study examined the effects of feeding levels up to 50% of modified distillers grains plus solubles (MDGS) on fatty acid composition in beef. Linear increase (P ≤ 0.05) …
