Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.
Download or read book The Effects of Dietary Yeast Extracts on Rumen Microbiota and Fermentation in a Dual Flow Continuous Culture Fermentation System written by Lauren M. Baker and published by . This book was released on 2021 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary yeast supplements are a popular feed additive in ruminant diets as its inclusion can favorably alter the rumen microbiota and fermentation, and subsequently improve animal health and production. Yeast are a rich source of amino acids, peptides, organic acids, carbohydrates, lipids, vitamins, and minerals. Inclusion of nutrient-rich yeast and yeast extracts in the diet promote the growth of select groups of rumen microbiota, subsequently improving digestibility, volatile fatty acids, and pH profile. However, the large variability within yeast types and composition has created inconsistent results on these parameters, and further investigation into yeast product variability is crucial for understanding its use in ruminant diets.The aim of this thesis was to evaluate six novel yeast extract treatments, different by origin and processing, and their influence on the abundance and diversity of rumen bacteria, protozoa numbers, digestibility, pH, and methane production. The study utilized a 6 x 6 Latin square design using dual-flow continuous culture fermenters (n = 6), including six 10-d periods consisting of 7-d of adaptation followed by 3-d of sample collection. Dietary yeast extract treatments were included at 4% on a dry matter (DM) basis of the total diet, where treatments and basal diets were combined and added to the fermenters twice daily in equal proportions (109 g DM total per fermenter/d). Treatments included 1) a Brewer's yeast extract with crude protein (CP) > 60% and a high degree of protein hydrolysis (BrE), 2) a blend of Brewer's yeast extract and Baker's peptone with CP > 65% and a mixture of high and low levels of protein hydrolysis and nucleotides (BrEPN), 3) a blend of Baker's yeast extract with CP > 50% and a mixture of high and medium levels of protein hydrolysis and nucleotides (BENH), 4) a blend of Baker's yeast peptone and yeast extract with CP > 65% and a mixture of high and low levels of protein hydrolysis and nucleotides (BEPN), 5) a blend of Baker's yeast peptone, Brewer's yeast autolysate, and Baker's yeast extract with CP > 50% and medium protein hydrolysis (BEPBrA), and 6) a blend of Baker's yeast extracts with CP > 60% and a mixture of medium and low levels of protein hydrolysis and nucleotides (BENL). Fermenter pH was recorded every minute using indwelling pH sensors, methane concentration was determined in triplicate twice daily at the time of feeding via a real-time gas analyzer system, and protozoa and bacteria samples were enumerated via microscopic and flow cytometry analysis, respectively. Bacterial DNA was extracted from harvested bacterial pellets for high-throughput sequencing of the 16S rRNA gene to determine bacterial abundance and diversity. Effluent samples were dried to determine DM disappearance and apparent digestibilities. Fermenter pH, methane, apparent digestibilities, and protozoa and bacteria enumerations were statistically analyzed via the PROC MIXED procedure of SAS. Fermenter pH, protozoa and bacteria counts, methane concentration, apparent digestibility, and bacterial abundance and diversity were not different across treatments. Yeast extract treatments provided at an inclusion rate of 4% on a DM basis, resulted in no differences on rumen microbiota and fermentation across treatments. Further examination of these yeast extract treatments in a dose-response study to determine efficacy as well as an in vivo study to determine their impact on animal health and production parameters could provide greater insight into the differences of yeast extract origin and processing in the rumen.
Download or read book The Rumen Microbial Ecosystem written by P.N. Hobson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.

This book was released on 2006-02-23 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asaresultofvarioushumanactivities,suchasincreaseinhumanpopulation,decrease in arable land due to soil degradation, urbanization, industrialization and associated increase in the demand for livestock products, dramatic changes are occurring in the global ruminant livestock sector. These changes includeshift inthesize of regional livestock populations and in the types of management and feeding systems under which ruminant livestock are held, and increased demand of a wider range of quality attributes from animal agriculture, not just of the products themselves but also of the methods used in their production. The livestock sector will need to respond to newchallengesofincreasinglivestockproductivitywhileprotectingenvironmentand human health and conservingbiodiversity and natural resources. The micro-organisms in the digestive tracts of ruminant livestock have a profound in?uence on the conversion offeedinto end products, which can impact on the- imal and theenvironment. As the livestock sector grows particularly in developing countries, there will be an increasing need to understand these processes for b- ter management and use ofbothfeed and other natural resources that underpinthe development of sustainable feeding systems.
Download or read book The Rumen and Its Microbes written by Robert E. Hungate and published by Elsevier. This book was released on 2013-10-22 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rumen and Its Microbes is a contribution to the ecology of this important microbial habitat. Relatively few microbial habitats have been subjected to a thorough quantitative ecological analysis. The rumen fermentation is peculiarly suitable because of its relatively constant and continuous nature and because of the very rapid rates of conversion of organic matter. Although analysis of the ruminant-microbe symbiosis is still far from complete, knowledge is sufficient for formulation of principles and for identification and measurement of important parameters. The first eight chapters of the book include a description of the rumen and its microbes, their activities, and the extent of these activities. This basic biology provides a framework in which applications to agriculture can be evaluated. These applications are discussed in the last four chapters: host metabolism, variation in the rumen, possible practical applications, and abnormalities in rumen function.
