This book was released on 2014 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight Holstein and 8 Jersey multiparous, lactating cows were used to complete 56 energy balances to determine the energy content of reduced-fat distillers grains and solubles (RFDDGS). A repeated switchback design was used to compare treatments with and without RFDDGS. Diets consisted of 24.2 % corn silage, 18.4 % alfalfa hay, 6.94 % brome hay with either 22.9 % rolled corn and 14.8 % soybean meal (Control), or 8.95 % rolled corn, 28.8 % RFDDGS, and 0 % soybean meal (Co-P; DM basis). The inclusion of RFDDGS did not affect (P = 0.86) DMI averaging 21.4 ± 0.53 kg DM for all cows but milk production tended (P = 0.10) to increase from 29.8 to 30.9 ± 1.46 kg/d for Control and Co-P treatments. There was no difference between treatments in milk fat percentage or ECM (P = 0.81 and 0.22, respectively), averaging 4.33 ± 0.14 % and 34.1 kg/d, respectively. Milk protein was decreased (P

Download or read book Using Indirect Calorimetry to Investigate Feeding Value of Byproducts for Lactating Dairy Cattle written by Mickayla Ann Marie Myers and published by . This book was released on 2018 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Byproducts have played a major role in dairy nutrition by providing a cheaper protein and fiber source, while also utilizing a product that would otherwise be waste from the human perspective. Use of byproducts in the dairy industry should allow for continued and overall increases in production and efficiency of the dairy industry. Two of the more popular byproducts in the dairy industry today are dried distillers grains and solubles and canola meal. In the first experiment, 12 multiparous lactating Jersey cows were used evaluate the feeding value of dried distillers grains and solubles (DDGS) or canola meal. A replicated 4 × 4 Latin square design was used to compare four different dietary treatments. Treatments were composed of a control (CON) containing no byproducts, a treatment diet containing 10% (DM basis) reduced fat DDGS (pDDGS), a 10% DDGS treatment with an alternative distillers grains source (aDDGS), and a 10% canola meal (CanM) treatment. Results suggest that milk production can be maintained when feeding these byproducts. However, energy utilization differences are observed, specifically in gross energy, digestible energy, metabolizable energy and energy balance (Mcal/kg of DM). The alternative source of DDGS contained the greatest amount of gross energy, digestible energy, and metabolizable energy. The control and the alternative source of DDGS contained the greatest energy balance. Dry matter, organic matter, crude protein, and neutral detergent fiber digestibility differences were also observed between treatments, specifically the control and the DDGS treatments had the greatest digestibility. In the second experiment, a comparison of sample preparation methods of urine to be analyzed for energy content by bomb calorimetry was conducted. The two methods to be tested included a lyophilization and oven drying method. Results of this study suggest that there were significant differences in gross energy content and total urine energy depending on which sample preparation method was used. The lyophilization method resulted in a greater gross energy and total urine energy compared to oven drying method, creating a negative method difference.

Download or read book Energy Value of De oiled Distillers Grains Plus Solubles in Beef Cattle Diets written by Meredith L. Bremer and published by . This book was released on 2014 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethanol plants are centrifuging off oil from the thin stillage stream as it has added market value currently. The impact of oil removal on cattle performance has been minimally researched. Thus four trials, one growing, one digestion, and two feedlot, were designed to determine the energy and feeding value of de-oiled distillers grains in beef cattle diets.In growing cattle diets, diet concentration of modified distillers grains plus solubles (MDGS) impacted cattle performance more than oil content. Ending BW, ADG, and G:F did not differ between cattle fed de-oiled or full fat MDGS, however cattle fed de-oiled MDGS had lower DMI than those fed full fat MDGS. No significant differences in fiber digestibility were observed between de-oiled and full fat MDGS treatments. The energy value of de-oiled MDGS in growing cattle diets was calculated to be 124% the value of corn.In finishing steer diets, increasing diet concentrations of de-oiled MDGS increased G:F. However, decreasing MDGS fat content from 12.0% to 7.2% decreased steer performance by 3.4%. No significant interactions were observed when increasing concentrations of de-oiled wet distillers grains plus solubles (WDGS) were fed with steam flaked (SFC) or dry rolled corn (DRC). Comparison of steer performance when de-oiled and full fat WDGS are fed in SFC and DRC diets resulted in no significant differences also.In growing and finishing diets small differences in cattle performance have been observed. Energy values for distillers grain in growing diets are still high with no improvements in fiber digestibility being observed. In finishing diets where distillers grains were fed at 30-35%, de-oiled distillers grains have 89% the feeding value of full fat distillers grain.

Book excerpt: The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded
Download or read book Effects of Reduced fat Distillers Grains with and Without Monensin on Performance and Nutrient Excretion of Dairy Cows written by Dennis L. Morris and published by . This book was released on 2017 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding a high-RFDG negatively affected long-term performance of dairy cattle via decreased DMI, milk fat and milk protein yield. The addition of monensin to a high-RFDG diet decreased milk fat and protein yield and long-term DMI. As expected RFDG increased P and S excretion, however, feeding RFDG instead of SBM decreased urinary N excretion. Additionally, monensin did not improve nutrient utilization or decrease nutrient excretion. This discrepancy with expectation could be a consequence of the negative affect monensin had on performance.
Download or read book Dried Distillers Grains Plus Solubles as a Protein and Energy Supplement for Beef Cattle written by Joel Blaine Corners and published by . 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.
