Download or read book Evaluation of Corn Condensed Distillers Solubles in Beef Cattle Diets and Grazing Double cropped Forages Following Corn Harvest written by Benjamin H. Hansen and published by . This book was released on 2017 with total page 119 pages. 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 2013 with total page 116 pages. 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 2008 with total page pages. 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

This book was released on 2004 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beef industry is in a constant search for new feedstuffs to be used in the production process. This occurs for several reasons. Nutritional support of gain in growing beef cattle needs to, at minimum, match improvements realized in the genetic capability for growth. Feed costs constitute one of the largest beef production costs and economics has dictated that feed cost per kilogram of gain be reduced to remain competitive in the world market. Manufacturing of goods for human consumption has created numerous by-products with little economic value for human use. Dried distillers grains with solubles (DDGS), a by-product of ethanol production, represents a product which could be used as a replacement for soybean meal (SBM) in cattle rations. A national need for fuel-grade ethanol has driven dramatic increases in its production and subsequent increases in DDGS supply. The state of Missouri has been targeted as an area for development of ethanol production. The by-product of the process, DDGS, is high in protein, digestible fiber, and lipid content. This makes it a potential Nitrogen and energy source for ruminant rations. A series of experiments was conducted to evaluate the impact of DDGS as a protein and energy source in beef cattle. We compared DDGS and SBM in growing heifers consuming corn-silage, soyhull, and corn-based diets to evaluate the performance and cost-effectiveness of the two supplements. Similar dietary N levels were evaluated. Inclusion of DDGS in the diet resulted in increased final weight, ADG, DMI, and lower cost of gain as compared to heifers consuming SBM. Grazing is utilized in a large portion of Missouri cattle production, with summer generally requiring supplementation. A study was conducted which evaluated increasing levels of DDGS for heifers grazing tall fescue. Performance criteria were evaluated for animals receiving 0.45, 0.91, or 1.36 kg DDGS and a 0.1 kg soyhull negative control. Average daily gain was quadratically improved as level of DDGS in the diet was increased, with 0.91 kg DDGS providing the greatest ADG. Intake of forage DM and cost of gain were not affected by treatment. The final experiment examined the post-ruminal amino acid flow of mature steers consuming timothy hay and supplemented with DDGS, SBM, a SBM/DDGS blend, or negative control. Supplementation increased duodenal flow of total essential and non-essential AA, while Met, Leu, and Trp were linearly increased by greater inclusion of DDGS in the diet. Dried distillers grains with solubles appears to be a valid replacement of SBM in highforage growing diets.

This book was released on 2018 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The effect of feeding corn by-products on cow reproductive performance, as well as offspring growth and reproductive performance has been investigated through four separate studies. The first study was conducted to evaluate the use of dried distiller’s grains with solubles (DDGS) in beef cow diets during early lactation on both dam and heifer offspring growth and reproductive performance. Three diets, consisting of 0, 2.5 or 4.7 kg/d DM of DDGS were formulated to be isocaloric but the DDGS diets exceeded protein requirements. Milk production was not different, however, milk components increased with the addition of DDGS. Resumption of cyclicity of dams, as well as days of age at puberty in heifer offspring were not different. However, while not statistically different, time-artificial insemination (TAI) rates of both cow and heifer offspring were numerically improved with the addition of DDGS in the diet. Plasma urea nitrogen (PUN) concentrations in the cows followed the trend of being higher with increasing levels of DDGS. While PUN concentrations did reach levels that are considered detrimental to fertility, they did not seem to have a negative impact on conception.In the second study, the use of corn gluten feed (CGF) in dam diets and its effects on their reproductive performance was investigated. Three diets, consisting of 0, 3.3 or 6.7 kg/d DM of CGF were formulated to be isocaloric but the CGF diets exceeded protein requirements. Milk production and milk components were not different with the exception of fat, which tended to be greater in the high CGF treatment. Resumption of cyclicity and TAI conception rates were not improved when CGF was added to the diet. Plasma urea nitrogen concentrations did not approached what would have been considered detrimental to fertility.The third study was conducted to evaluate feeding DDGS during the second trimester or the second and third trimester (3.0 or 3.5 kg/d DDGS, respectively), on heifer offspring reproductive performance. Growth performance of heifer offspring did not differ among treatments. There were no differences in TAI conception rates in heifer offspring from dams fed DDGS but, dominant follicles tended to be larger in heifer offspring from dams fed DDGS during the second trimester. Due to the lack of improvement in reproductive performance in this study, it has been hypothesized that lactation may be a more critical time point for improvements in heifer offspring reproductive performance.The fourth study followed the hypothesis of the third study. Because heifer offspring reproductive performance was positively impacted when dams were fed DDGS during early lactation, evaluation of dams fed DDGS during early lactation on bull offspring performance was investigated. Bull offspring growth performance was not impacted by dam diets during early lactation. Scrotal circumference, testosterone concentrations and semen analysis were used to evaluate days of age at puberty, however, puberty attainment in bull offspring was also not impacted. In summary, feeding DDGS as a primary source of dietary energy during early lactation had a positive impact on both cow and heifer offspring reproductive performance, but this does not seem to be true for bull offspring.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Six experiments using 3,659 nursery and finishing pigs were conducted to evaluate the effects of dietary soybean hulls and ingredient processing in corn-soybean meal or corn-soybean meal-DDGS diets on nursery and finishing performance. Experiment 1 tested increasing soybean hulls (0, 5, 10, 15, and 20%) and increasing soybean hulls decreased ADG and G:F. Experiment 2 evaluated increasing soybean hulls (0, 10, and 20%) in diets balanced or not for NE and showed reduced performance with increasing soybean hulls. Balancing for NE resulted in G:F similar to pigs fed the control. Experiments 3 and 4 evaluated increasing dietary soybean hulls in corn-soybean meal and corn-soybean meal-DDGS diets. Soybean hulls in either diet worsened G:F and improved caloric efficiency, suggesting current INRA (2004) values for soybean hulls underestimate their energy value. Experiment 5 evaluated 10 and 20% ground or unground soybean hulls in meal and pelleted diets. Caloric efficiency improved with high levels of soybean hulls. Pelleting improved ADG and eliminated negative effects on G:F with increasing soybean hulls, while grinding soybean hulls reduced performance. Experiment 6 tested increasing ground and unground soybean hulls (0, 7.5, and 15%). Increasing soybean hulls worsened G:F, carcass yield, and hot carcass weight. Grinding soybean hulls to finer particle sizes did not improve ADG and worsened G:F. Experiments 7 and 8 evaluated the replacement of corn with wheat and crystalline amino acids in nursery and finishing pig diets. Replacing 50% of corn with wheat did not affect growth performance in either nursery or finishing; however 100% replacement of corn with wheat reduced performance. In addition, feeding wheat improved carcass fat IV, while use of high levels of crystalline amino acids in wheat-based diets did not influence performance in either study. Experiment 9 evaluated the replacement of soybean meal with high-protein dried distiller's grains with solubles and crystalline amino acids. High-protein DDGS and crystalline AA can replace 50% of the SBM in finishing diets without negatively affecting performance or carcass yield. Replacing 100% of SBM with high-protein DDGS reduced growth rate, but increasing crystalline AA levels can help mitigate negative effects on carcass yield and fat IV.
