Download or read book Nitrogen Utilization in Dairy Cattle Consuming Rations Containing Corn Milling Co products written by Amanda Mary Gehman and published by . This book was released on 2009 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased demand for products synthesized from corn starch, such as ethanol and high fructose corn syrup, has resulted in an increased supply of corn milling co-products, such as wet distillers grains with solubles (WDGS ) and wet corn gluten feed (WCGF). These products differ in chemical and physical properties from corn as well as common forages. While the effects of feeding corn milling co-products on intake and milk production in lactating dairy cattle has been researched, effects on nitrogen utilization have not been studied in detail. Two experiments were conducted to study the effects of feeding WDGS and WCGF on digestibility, ruminal microbial protein synthesis, and nitrogen excretion. ^ Experiment 1 examined the potential complementary nutritional effects of feeding WDGS and WCGF together and to explore the means of maximizing total inclusion of co-products in rations for dairy cattle. Total tract N digestibility and microbial protein synthesis increased for the ration containing WDGS and WCGF. Fecal N excretion did not increase, while urinary N increased compared the control; however, manure N excretion was similar. Treatments did not differ in 4% fat-corrected milk. Results suggest that dairy rations can be balanced to include a 30% blend of WDGS and WCGF while maintaining similar manure N excretion and milk production as compared to a ration without co-products. ^ Experiment 2 examined the effects of forage type when feeding high levels of WDGS. Lactating cows were fed rations varying in levels of WDGS (0 or 25% DM) and forage type (corn silage or alfalfa silage). Microbial protein synthesis increased for rations containing WDGS regardless of forage type. Fecal N excretion was not different among treatments, but compared to a zero control, urinary and manure N was reduced with WDGS. Both the inclusion of WDGS and alfalfa silage improved 4% fat-corrected milk production. This research demonstrated rations can be formulated to contain 25% WDGS and result in reduced N excretion regardless of forage type, while improving milk production.^

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.

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).

Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management Addresses the urgent issue of sustainability in modern animal agriculture Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
