Available in PDF, EPUB and Kindle. Book excerpt: New coproducts are continually developed in the ethanol production industry. With that, the new product originates from the dry milling process which is unlike the traditional process as nitrogenous based particles are concentrated from the residual fiber by sieving post fermentation. Although high protein coproducts have been available since the mid 2000’s. These new products must be evaluated for chemical composition so that they can be accurately described in feed libraries that are used in commercial ration formulation software. While chemical composition provides us an initial and useful description of a feed product, in vivo nitrogen and energy balance studies are needed to examine the utilization and efficiency of converting the nutrients within a given feed product to milk. Therefore, it is integral to analyze both components for accurate and effective ration formulation in the field. The first experiment analyzed 10 samples of a new high protein coproduct that were obtained from a singular production site over one months period for chemical composition and nutrient availability. Samples were analyzed for DM, CP, Soluble CP, ADICP, NDICP, ADF, aNDF, lignin, EE, sugar, starch, minerals, amino acids, and fatty acids. Also, aNDF was determined for the samples by 3 different commercial fiber systems including refluxing method, bagged sample method, and a confined refluxing and filtering method. For nutrient availability, RUP was determined with in situ and mobile procedures and NDF digestibility at 24, 30, 48, and 240 h. Total tract NDF iii digestibility was also estimated. Results suggest that the new high protein coproduct contains increased concentration of protein and lysine and reduced fiber when compared to a traditional DDGS. The second experiment utilized twelve multiparous lactating Jersey cattle in a triplicated 4 × 4 Latin square design. Animals were assigned to 4 different treatments diets with increasing inclusion from 0 % to 8 % of the new high protein coproduct replacing non-enzymatically browned soybean meal. The experiment aims to test the effects of formulation of the new product as well as quantify the whole animal energy and nitrogen balance. Results indicate that increasing inclusion of the new high protein coproduct increased dietary fatty acids. However, it had no effect nutrient digestibility. The utilization of energy for NEL increased with increasing inclusion of the HPCoP with subsequent increases in milk fat production. Results indicate that the new high protein coproduct is able to effectively replace non-enzymatically browned soybean meal in lactating dairy rations.

Book excerpt: In recent years, there has been a dramatic increase in grain-based fuel ethanol production in North America and around the world. Whether such production will result in a net energy gain or whether this is sustainable in the long term is under debate, but undoubtedly millions of tons of non-fermented residues are now produced annually for global trade in the form of distillers dried grains with solubles (DDGS). Consequently, in a short period of time a tremendous amount of research has been conducted to determine the suitability of ethanol coproducts for various end uses. Distillers Grains: Production, Properties and Utilization is the first book of its kind to provide in-depth, and up-to-date coverage of Historical and current status of the fuel ethanol industry in the U.S. Processing methods, scientific principles, and innovations for making fuel ethanol using grains as feedstock Physical and chemical properties of DDGS, assay methodologies for compositional analyses, and mycotoxin occurrence in DDGS Changes during processing (from grains to DDGS) and analysis of factors causing variations in compositional, nutritional, and physical values Various traditional, new, and emerging uses for DDGS (including feed for cattle, swine, poultry, fish, and other animals, feedstocks for cellulosic ethanol, biodiesel, and other bioenergy production, and substrates for food and industrial uses) Appealing to all who have an interest in fuel ethanol production, distillers grains, and their uses, this comprehensive reference sharpens the readers’ understanding of distillers grains and will promote better utilization of ethanol coproducts. Animal and food scientists, feed and food technologists, ethanol plant managers and technicians, nutritionists, academic and governmental professionals, and college students will find the book most useful.

Download or read book Determining Fiber and Protein Degradation Rates of Corn Milling co products and Their Effects on Rumen Bacterial Populations and Lactating Dairy Cow Performance written by Whitney Williams and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn milling (co)products (n=120) were evaluated for their neutral detergent fiber residue (NDR) and neutral detergent insoluble protein (NDIP) ruminal degradation rates using several in vitro methods. Two (co)products (BPX-DDGS and HP-DDG) were fed to lactating dairy cows (n=44) to evaluate effects on milk production. The Cornell-Penn-Miner Institute (CPM) Dairy model was used to formulate diets and predict milk production. In vitro determined NDR and NDIP rates and were compared to CPM-dairy feed library values, and model predictions were compared with observed milk production. Additionally, BPX-DDGS and HP-DDG were defatted and compared with their intact forms for fermentation characteristics using the in vitro gas production (IVGP) technique. Fermentations were analyzed for rumen bacterial population shifts using the 16S rDNA bacterial tag encoded FLX amplicon pyrosequencing (bTEFAP) technique. Lastly, a novel ruminal in vitro method was described to measure the soluble protein fraction of feeds, with adjustments for microbial contamination. Fermentation rate of the NDR of BPX-DDGS and HP-DDG (0.08 and 0.07 h^-1, respectively) and NDIP degradation rates (0.07 and 0.06 h^-1, respectively) were similar to CPM-dairy feed library NDR and NDIP rates of corn distillers grain (0.07 and 0.05 h^-1, respectively). Model predictions using standard and in vitro determined values did not differ. As BPX-DDGS decreased and HP-DDG increased in the diet, observed milk production tended to decrease linearly (P = 0.08). There was a cubic effect for milk fat percent (P = 0.03) and a cubic trend for milk fat yield (P = 0.09). Milk protein yield also tended to decrease linearly (P = 0.06). CPM-dairy model prediction accuracies were less than 50 percent. Defatting (co)products reduced lag time and fractional rate of fermentation by at least half for BPX-DDG, and had no effect on HP-DDG. Defatting both (co)products increased the fibrolytic (26.8 to 38.7 percent) and proteolytic (26.1 to 37.2 percent) bacterial guild populations and decreased the lactate-utilizing bacterial guild (3.06 to 1.44 percent). The novel ruminal in vitro method determined that the specific activity of ammonia production was not different among (co)products. However, results were within numerical range of previously used methodologies.
Download or read book Effect of Feeding Corn Silage Based Diets Predicted to be Deficient in Either Ruminal Nitrogen Or Metabolizable Protein on Nitrogen Utilization and Efficiency of Use in Lactating Cows written by Erin Beth Recktenwald and published by . This book was released on 2007 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to concern over nitrogen (N) emissions, this study attempted to evaluate dietary approaches to reduce N excretion by dairy cattle. Knowledge about potential N sources that were either unaccounted for or under-predicted by CPM Dairy and the Dairy NRC (2001) was used to formulate rations that were much lower in crude protein (CP) than typically fed to dairy cattle but would potentially not decrease production. Specifically, the three diets fed were predicted to have: (1) positive rumen N and metabolizable protein (MP) balances (Diet P) (2) negative MP balance and positive rumen N balance (Diet N), or (3) negative rumen N balance but positive MP balance (Diet T) as predicted by CPM Dairy version 3. The objective of this experiment was to determine whether, and to what extent, the decrease in predicted ruminally available N and MP supply would affect milk production. Eighty-eight multiparous lactating Holstein cows (83 ± 20 DIM), were blocked by average daily milk yield to 50 DIM and parity and assigned to three diets differing in N content or predicted rumen degradability of the feed N. The diets were formulated with CPM Dairy V3 using library values for all feeds except corn silage where actual chemical, digestibility, and degradation rate values were determined and used. The diets (DM basis) consisted of approximately 50% corn silage, 2% wheat straw and 48% of a diet specific ingredient mix and were formulated for 22.2 of kg DMI. Actual diet CP levels were 16.7, 14.2 and 14.3% for Diets P, N and T, respectively. The predicted CPM Dairy rumen N balance at the formulated DMI was 29 and 27 g for Diets P and N and negative 39 g/d for Diet T, whereas the predicted MP balance was 263 and negative 145 and 91 g/d for Diets P, N and T, respectively. Monensin was included in the diets at a formulated intake of approximately 300 mg per cow per d and somatotropin was administered per label. Actual DMI for cattle fed these treatments were 25.7, 25.5 and 24.2 kg/d for Diets P, N and T, respectively and were significantly lower for Diet T. Actual milk yield was 45.0, 42.6 and 43.3 kg/d and 3.5% FCM was 38.1, 36.5, and 36.4 kg/d for cows fed Diets P, N and T, respectively and was significantly lower for cows fed Diets N and T. Milk protein percent was not affected by diet; however, milk protein yield was significantly greater for cows fed Diet P due to the difference in milk yield. Plasma urea N concentrations were 11.31, 8.40 and 7.13 mg/dl for cows fed diets P, N and T, respectively and were different and paralleled the rumen ammonia levels of 8.32, 6.58 and 5.84 mg/dl. Milk fat depression (MFD) was observed in all cows and was not affected by treatment, and the average milk fat levels were 2.67, 2.68 and 2.54% for diets P, N and T, respectively. To determine if monensin was partially responsible for the MFD, monensin was removed from the diets of approximately half of the cows on treatment once they had finished the experimental period. Removal of monensin resulted in a 30% increase in milk fat percent, and milk protein content was not affected. Calculated milk N:intake N ratios for the three treatments were 0.31, 0.33 and 0.36 for Diets P, N and T respectively. The results of this study suggest that more productive N is available than currently predicted by either CPM Dairy and the Dairy NRC (2001). Understanding where these differences exist would allow for feeding less CP to dairy cattle and decreasing N emissions to the environment. It may also be a profitable strategy for dairy farmers, as they would be able to reduce their purchase of costly protein feeds, but that was not demonstrated in this study - primarily due to the severe milk fat depression that decreased the economic value of milk. However, ration cost was not a concern for this experiment, and that aspect can be considered when implementing feeding strategies stemming from this research. (Abstract).
