Download or read book Effects of Ad Libitum Supplement Containing Increasing Levels of Microalgae Scenedesmus Sp on Site and Extent of Digestion and Elavuation of Microbial Diversity in the Rumen of Beef Heifers Consuming a Forage Based Diet written by Colleen Michelle Buck and published by . This book was released on 2015 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of feedstuffs containing a high level of crude protein and ash, such as microalgae, Scenedesmus sp., could serve as a supplement on rangelands with the potential to limit intake. Four crossbred heifers (avg BW 409 ± 18kg) fitted with ruminal and duodenal cannulas were used in a 4 x 4 Latin square. Heifers had ad libitum access to chopped (2.54 cm) Sorghum-Sudan hay (8.8% CP and 71% NDF, OM basis) and one of four pelleted dietary treatments: 1) soybean meal based (SBM) supplement (53.0% SBM, 37.9% Soybean hulls, 9.1% molasses, DM basis; CON); 2) Scenedesmus sp. (microalgae) at 17% of DM (33.3% soybean hulls, 37.7% SBM, 17% microalgae, 8.7% molasses, DM basis; 17%); 3) 42% microalgae (42% Microalgae, 30.3% soyben hulls, 18.9% SBM, 9.1% molasses, DM basis; 42%); 4) 66% microalgae (66% microalgae 24% soybean hulls, 9% molasses, DM basis; 66%). Supplements were formulated to be isonitrogenous. Trial consisted of four 21 d periods with 17 d adaptation and 4 d of intensive sampling. Objectives of the study analyzed digestion and fermentation characteristics along with changes in the rumen microbiome with inclusion of microalgae to the diet. Microalgae levels decreased supplement and total OM intake linearly (P ≤ 0.002). Duodenal and microbial OM flow, post ruminal OM disappearance and total tract OM disappearance decreased (P ≤ 0.02) with microalgae inclusion. Nitrogen intake, total duodenal N flow, microbial duodenal N flow, duodenal ammonia N flow and non-microbial non-ammonia non-nitrogen decreased linearly (P ≤ 0.008) as microalgae level in the supplement increased. Ruminal pH increased linearly (P = 0.006), and ruminal ammonia concentrations decreased linearly (P = 0.001) with the inclusion of microalgae. Total ruminal VFA concentrations decreased linearly (P = 0.001) while ruminal molar proportions of acetate increased (linear, P = 0.02) with increasing levels of microalgae. Metagenomic analysis resulted in the genus Blautia increasing (P = 0.002) when CON was compared to microalgae. In conclusion the addition of increasing levels of microalgae in a CP supplement limited intake of the supplement with little change to microbial populations when heifers had ad libitum access to forage based diet.

Download or read book Energy from Microalgae written by Eduardo Jacob-Lopes and published by Springer. This book was released on 2018-02-19 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an authoritative and comprehensive overview of the production and use of microalgal biomass and bioproducts for energy generation. It also offers extensive information on engineering approaches to energy production, such as process integration and process intensification in harnessing energy from microalgae. Issues related to the environment, food, chemicals and energy supply pose serious threats to nations’ success and stability. The challenge to provide for a rapidly growing global population has made it imperative to find new technological routes to increase the production of consumables while also bearing in mind the biosphere’s ability to regenerate resources. Microbial biomass is a bioresource that provides effective solutions to these challenges. Divided into eight parts, the book explores microalgal production systems, life cycle assessment and the bio-economy of biofuels from microalgae, process integration and process intensification applied to microalgal biofuels production. In addition, it discusses the main fuel products obtained from microalgae, summarizing a range of useful energy products derived from algae-based systems, and outlines future developments. Given the book’s breadth of coverage and extensive bibliography, it offers an essential resource for researchers and industry professionals working in renewable energy.

Download or read book Life Cycle Sustainability Assessment LCSA written by Subramanian Senthilkannan Muthu and published by Springer Nature. This book was released on 2021-09-21 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Life Cycle Assessment (ELCA) that was developed about three decades ago demands a broadening of its scope to include lifecycle costing and social aspects of life cycle assessment as well, drawing on the three-pillar or ‘triple bottom line’ model of sustainability, which is the result of the development of the Life Cycle Sustainability Assessment (LCSA). LCSA refers to the evaluation of all environmental, social and economic negative impacts and benefits in decision-making processes towards more sustainable products throughout their life cycle. Combination of environmental and social life cycle assessments along with life cycle costing leads to life cycle sustainability assessment (LCSA). This book highlights various aspects of life cycle sustainability assessment (LCSA).

Download or read book Fisheries Processing written by A.M. Martin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fish processing industry is still far from the levels of scientific and technological development that characterize other food processing oper ations. It has also been slow in finding uses for by-products and processing wastes, compared with the meat and poultry industries. The utilization of fisheries by-products or wastes constitutes an area in which the application of modern techniques could potentially improve profitability. At present, increased attention is being focused on the application of new biotechnological methods to operations related to the seafood industry, with the objective of increasing its general efficiency. Because fish processing operations are commonly carried out in the vicinity of the sea, most of the resulting fish wastes have been disposed of by returning them to it. Pollution control measures and a better understanding of the valuable composition of the products extracted from the sea are expected to encourage their recovery and the develop ment of new products from them. In the past, fisheries wastes and species not used for food have been generally utilized through techno logical processes with a low level of sophistication, such as those for the production of animal feed and fertilizer. Limited economic success has accompanied the application of physi cal and chemical processes for the recovery of non-utilized fisheries biomass and for the production of quality products from them.
Download or read book Bivalve Filter Feeders written by Richard F. Dame and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bivalve filter-feeding mollusks are important components of coastal ecosystems because they remove large quantities of suspended material from the water and excrete abundant amounts of reactive nutrients. These animals are also major prey for numerous predators including birds, fish, mammals, and invertebrates; furthermore, they are significant food resources for humans. While studies on the organismic and population level have dominated bivalve ecology, the recent focus on the ecosystem roles of filter feeding systems has led to larger-scale investigations. With this approach the specific topics of physiology, grazing, predation, nutrient cycling, physical environment, computer simulation modeling, and environmental management are combined into a meaningful whole.

Download or read book Energy and Protein Metabolism and Nutrition written by Mario Luiz Chizzotti and published by Brill Wageningen Academic. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.
