This book was released on 2017. Available in PDF, EPUB and Kindle. Book excerpt: Corn condensed distillers solubles (CDS) is a protein and energy dense by-product from dry-milled production of ethanol. Recent oil extraction has posed modifications to the nutrient profile of CDS, suggesting that de-oiled CDS needs to be re-evaluated in beef cattle diets. Three experiments were conducted to evaluate the effects of CDS in high-concentrate diets, forage-based diets, as well as evaluate the effects of CDS on diet digestibility and rumen fermentation parameters in forage-based diets. Feeding CDS in high-concentrate diets up to 20% of the diet DM or in combination with wet distillers grains plus solubles (WDGS) improved performance and resulted in greater energy value compared to corn. Feeding values of 20% CDS or the combination of 16% CDS and 20% WDGS were 147 and 129% compared to corn, respectively. Feeding CDS in forage-based diets up to 40% of the diet DM diminished performance and resulted in a lesser energy value compared to corn. Linear decreases were observed in total tract digestibility of NDF and the acetate to propionate ratio in rumen fluid. Double-cropped forages following corn harvest offer livestock producers an opportunity to extend their grazing season on high quality forage in the fall. Additionally, crop producers may benefit from the implementation of grazing animals due to added soil nutrients and removal of residue. Therefore, an experiment was conducted to evaluate the effects of double-cropped oats following corn silage (CS) or high-moisture corn (HMC) on calf gains, forage production, and subsequent cash crop yields. Oats seeded after CS produced more forage biomass than oats seeded after HMC. Both treatments produced high quality oats (22% CP, 39% NDF, and 24% ADF averaged across treatments). Calf gains were greater grazing oats following CS compared to HMC at 1.10 and 0.84 kg / d, respectively. Across 1-yr of data, subsequent cash crop yields were not different for HMC and soybeans with increased CS yields in both covered/grazed and non-covered/non-grazed treatments compared to the covered/non-grazed treatment..

This book was released on 2008. Available in PDF, EPUB and Kindle. Book excerpt: Three trials were conducted using dried distiller's grains with solubles (DDGS) to evaluate effects on feedlot performance, carcass characteristics, ruminal fermentation, and diet digestibility in cattle fed steam-flaked corn-based diets. In trial 1, crossbred yearling heifers were used in a finishing trial to evaluate interactions between corn-DDGS feeding levels and roughage source (alfalfa hay vs corn silage) in terms of impact on feedlot performance and carcass characteristics. Experimental diets were based on steam-flaked corn and contained 0% DDGS with 6% alfalfa hay (AH), 0% DDGS with 10% corn silage (CS), 25% DDGS with 6% AH, or 25% DDGS with 10% CS (DM basis). Results indicated no interaction between levels of DDGS and roughage source. Heifers fed DDGS as a partial replacement for steam-flaked corn had similar growth performance and carcass merit compared to heifers fed diets without DDGS. Corn silage and alfalfa hay were comparable roughages when a portion of steam-flaked corn was replaced with DDGS. The second trial was a companion metabolism study in which ruminal fermentation characteristics and diet digestibility were examined in 12 cannulated Holstein steers fed steam-flaked corn finishing diets with or without DDGS, using alfalfa hay or corn silage as roughage sources. Diets were similar to those fed in the performance study and consisted of steam-flaked corn with 0 or 25% DDGS (DM basis) and 6% AH or 10% CS (DM basis). Feeding DDGS decreased ruminal pH and ruminal ammonia concentrations, and digestion of DM and OM were less compared to diets without DDGS. The decrease in digestibility was largely attributable to poorer digestion of CP and, to a lesser extent, a reduction in starch digestion. The third study was designed to investigate effects of pH (5.0, 5.5, and 6.0) on in vitro fermentative activity by ruminal microorganisms from cattle adapted to a finishing diet containing 25% DDGS (DM basis). Higher pH led to greater dry matter disappearance in vitro (P

Download or read book Effects of Drying Distillers Grains Plus Solubles on Feedlot Cattle Performance and Nutrient Digestibility written by Brandon L. Nuttelman. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: All dry milling ethanol plants produce wet distillers grains (WDG) and distillers solubles (DS). Depending on the plant, WDG and DS will be combined to produce wet distillers grains plus solubles (WDGS). Some plants will partially dry WDGS and market modified distillers grains plus solubles (MDGS), or other plants will completely dry WDGS to produce dried distillers grains plus solubles (DDGS). These products have been shown to contain greater feeding values than the corn it replaces in finishing diets. However, as drying intensity of distillers grains plus solubles (DGS) increases, the feeding value relative to corn decreases. Three finishing experiments and two metabolism experiments were conducted to evaluate the effect drying WDGS has on finishing cattle performance and carcass characteristics and the effects on nutrient digestibility. Diets containing DGS had greater ADG and were more efficient than the corn-based control. As a result, cattle fed DGS had heavier HCW and greater 12th rib fat thickness at harvest. Using the G:F values, all types of DGS regardless of moisture content had greater feeding values than the corn it replaced. Additionally, WDGS had greater feeding values than MDGS and DDGS, and MDGS had a greater feeding value than DDGS. Although not significant, diets containing WDGS had numerically greater NDF digestibility than diets containing DDGS. Organic matter digestibility was improved for WDGS compared to DDGS. Completely and partially drying WDGS reduces the feeding value in finishing diets and reduces OM digestibility.

This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Wet distiller's grains with solubles are the most common feedstuff generated by the ethanol industry, and this feedstuff has been utilized by the feedlot industry. Exploration of the effect of dietary distiller's inclusion on the form and quantity of protein or nitrogen (N) has received little attention. Assessment of degradable N needs in diets containing wet distiller's grains with solubles (WDGS) is needed to aid the cattle feeding industry in managing feed costs and potential environmental issues. In Exp. 1, 525 yearling steers (initial weight = 373 ±13 kg) received treatments in a 2 x 3 1 factorial. Factors included corn WDGS (15 or 30 percent of DM) and non-protein N (NPN; 0, 1.5, or 3.0 percent of DM) from urea. The control diet without corn WDGS contained 3.0 percent NPN (1.06 percent urea) and cottonseed meal. Overall gain efficiency among steers fed 15 percent corn WDGS was greatest for 1.5 percent NPN and least for 0 percent NPN (P = 0.07, quadratic), whereas gain efficiency decreased linearly (P 0.09) as NPN increased in the 30 percent WDGS. Dressing percent was greater (P 0.01) for the control diet than for 15 percent or 30 percent WDGS. In Exp. 2, 296 steer calves (initial BW = 344 ±12 kg) were adapted to a common finishing diet, blocked by BW, and assigned to treatments. Experimental diets included a control diet without WDGS (contained 3 percent NPN from urea, and cottonseed meal) and 15 percent WDGS with either 1.50, 2.25, or 3.00 percent NPN (0.52, 0.78, and 1.04 percent urea, respectively, on a DM basis). Overall gain efficiency on either a live or adjusted basis was not different among treatments (P 0.15). Dietary NPN concentration did not influence growth performance (P 0.21). Results suggest that optimum performance for cattle fed 15 percent WDGS occurred when the diet contained between 1.5 percent and 2.25 percent NPN. However, removing all supplemental NPN was necessary to support optimum performance in diets containing 30 percent WCDG.
