Available in PDF, EPUB and Kindle. Book excerpt: Globally, dairy and beef production has become an extremely competitive industry. While the world milk production is predicted to grow significantly by 2020 with the emergence of new consumers in developing countries, milk and meat production in the more establish markets now has to fulfil new societal needs beside the simple product supply: animal health, food safety, and production environmental impact are some of them. At the same time, the recent extreme increase in feed costs emphasizes again the key role of rumen and gut efficiency management in production economics. All these new thematic topics are central to the proper management of ruminant digestive process. Producers must endeavour to seek new technologies to improve production efficiency, animal health and production costs while keeping in mind the environmental impact these changes make. ‘Gut efficiency; the key ingredient in ruminant production’ brings together some of the world’s leading authorities in the field of ruminant nutrition and production. It considers the importance of digestive health in performance achievement together with novel strategies to manage it. It is aimed at nutritionists, veterinarians and animal producers as well as students and researchers studying animal and applied biological sciences.

This book was released on 2018-03-13 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruminants were domesticated in the Middle East about 10,000 years ago and have since become an inseparable part of human diet, society, and culture. Ruminants can transform inedible plant fiber and non-protein nitrogen into meat, milk, wool and traction, thus allowing human utilization of non-tillable land and industrial by-products. The nutritional flexibility of ruminants is conferred by the rumen´s complex microbial community. Driven by rising income and population growth in emergent economies, the global demand for livestock products, including milk and meat from ruminants, has been increasingly growing, and is predicted to continue growing in the next few decades. The increase in production necessary to satisfy this rising demand is putting much pressure on already dwindling natural resources. There are also concerns about the emissions of methane and nitrous oxide, potent greenhouse gases associated to ruminant production. The need to make ruminant production more efficient in the use of natural resources poses a big challenge to ruminant science, and within it, rumen microbiology. Recent years have seen important advances in basic and applied rumen microbiology and biochemistry. The knowledge generated has significant implications for the efficiency and sustainability of ruminant production and the quality of ruminant products for human health. The present compilation is an update of recent advances in rumen microbiology and ruminant digestion and fermentation, including original research, reviews, and hypothesis and theory articles. We hope that the experimental results, discussion, models and ideas presented herein are useful to foster future research contributing to sustainable ruminant production.

This book was released on 2009 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The primary source of protein for milk production is of microbial origin, so increasing microbial protein supply should either increase milk protein or decrease the need for expensive bypass protein. Moreover, improving the consistency of prediction of microbial protein supply decreases the amount of protein that must be fed to the dairy cow, reducing urinary N excretion and decreasing feed costs. Methionine is co-limiting with lysine in most dairy diets. 2-hydroxy-4-(methylthio) butanoic acid (HMBi) is a methionine precursor for bacteria and might be degraded more slowly and, therefore, might be sustained longer over the feeding cycle for bacterial uptake or absorption than methionine itself. To show the effect of HMBi and methionine on bacterial population structure and protein synthesis, we used four continuous culture fermenters inoculated with rumen fluid from two lactating Holstein cows. We fed the cultures a normal dairy ration with a 50/50 ratio of concentrate and alfalfa thrice per day. Our experimental design was a 4x4 Latin square. Our treatments were control (CON), 0.11% HMBi (HMBi), 0.097% methionine (MET), and 0.055% HMBi plus 0.048% methionine (HMBi + MET). All doses were on an equivalent methionine molar basis. We dosed the stable isotopes 1-13C-methionine, 3D-methionine (methyl hydrogens labeled with deuterium) and U-13C-HMBi into the fermenters at six consecutive feedings to trace the incorporation of the carbon skeletons into microbial protein and methylation of substrates by methionine. We also infused NH3-N15 with the buffer during each period to measure efficiency of microbial protein synthesis. The data were compared using three orthogonal contrasts, all methionine treatments versus control and the linear and quadratic responses to methionine substitution by HMBi. Supplementation of methionine and HMBi had no effect on digestibilities of ADF and true OM. NDF and hemicellulose digestibility were linearly affected (P=0.04 and P

Download or read book Rumen Microbiology From Evolution to Revolution written by Anil Kumar Puniya and published by Springer. This book was released on 2015-07-11 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an in-depth description of different groups of microbes (i.e. bacteria, protozoa, fungi and viruses) that exist in the rumen microbial community, and offers an overview of rumen microbiology, the rumen microbial ecosystem of domesticated ruminants, and rumen microbial diversity. It provides the latest concepts on rumen microbiology for scholars, researchers and teachers of animal and veterinary sciences. With this goal in mind, throughout the text we focus on specific areas related to the biology and complex interactions of the microbes in rumen, integrating significant key issues in each respective area. We also discuss rumen manipulation with plant secondary metabolites, microbial feed additives, utilization of organic acids, selective inhibition of harmful rumen microbes, and ‘omics’ approaches to manipulating rumen microbial functions. A section on the exploration and exploitation of rumen microbes addresses topics including the current state of knowledge on rumen metagenomics, rumen: an underutilized niche for industrially important enzymes and ruminal fermentations to produce fuels. We next turn our attention to commercial applications of rumen microbial enzymes and to the molecular characterization of euryarcheal communities within an anaerobic digester. A section on intestinal disorders and rumen microbes covers acidosis in cattle, urea/ ammonia metabolism in the rumen and nitrate/ nitrite toxicity in ruminant diets. Last, the future prospects of rumen microbiology are examined, based on the latest developments in this area. In summary, the book offers a highly systematic collection of essential content on rumen microbiology.

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.
