Sharma and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present investigations were carried out to develop slow release products by complexing urea with formaldehyde in various molar proportions by refluxing at various temparatures and study their efficiency on the rate of hydrolysis microbial protein synthesis as well as efficiency of feed utilisation and growth in crossbred calves. The increase in the molar proportion of urea:HCHO and temparature of refluxing at the time of preparation of slow release urea formaldehyde comlexes (SRUFC, s) decreased the total introgen solubality. THe percent hydrolysis rates also decreased with the increase in temparatures of refluxing and molar proportions of urea:HCHO used in the preparation of complexes. The 35s in carporation into bacterial cells decreased with the increaseing refluxing temparature of the SRUFC, s. Maximum percentage of 35s in carporation was achieved with the complexes acidified with H2SO4 complexing urea with HCHO resulted in the increased efficiency of microbial protein formation in the rumen complexes contributed significantly to the TVPA poolas well as TVFA production rates possibly through increased microbial activity in rumen. The bacterial production rates were more in slow release urea formaldehyde complexes as compared to those observed in control and urea fed animals the rumen fluid volumes and its flows rates were not influenced by the inclusion of even urea in the diets. Dry matter organisms matter crude fibre and nitrogen free extract digestibilities were not influenced by the inclusion of either urea is SRUFCs. The retention of nitrogen was significantly higher in animals fed on NPN sources as compared to control diet. Increased efficiency of N-utilization from the complexes were observed compared to that when urea was fed as such to the calves. THe SRUFC 11 (acidified complex) was superior to urea as well as SRUFC 1 (non acidified) as for as dry matter consumption and growth rates of animals were concened. Both the dry matter and cp disgestibilities increased significantly on SRUFC 11 feeding as composition values in terms of fat protein ash and energy did not reveal any significant differences in the various groups due to treatment.

This book was released on 2002-03-31 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive and updated review of fundamental studies on inhibition of soil urease activity and of applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years and the patent literature comprises a period of nearly 40 years. The potential of food production to meet the growing needs related to population increase is largely conditioned by the efficiency of agricultural fertilizers. Urea has gradually become the most important nitrogen fertilizer in world agriculture. However, its efficiency is in general reduced due to excessive activity of a soil enzyme, urease. One way to increase efficiency of urea fertilizers is the inhibition of soil urease activity. In the last four decades, multilateral investigations have been carried out in a series of countries to identify and test unpolluting and inexpensive chemical compounds to be used as inhibitors of soil urease activity. These investigations are reviewed, including those described in the patent literature. The book is addressed to a broad audience, including experts and students in agronomy, forestry, plant physiology, soil science (especially soil biology and biochemistry), and other environmental sciences, as well as in organic and inorganic chemistry.

Download or read book Nutritional Ecology of the Ruminant written by Peter J. Van Soest and published by Cornell University Press. This book was released on 2018-09-05 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume examines the interrelationships of nitrogen and energy nutrition of ruminants. It provides exhaustive coverage of basic concepts, applications, and new research developments.Rumen microbial activity is emphasized. The author, an expert in animal nutrition, discusses new systems of determining dietary energy requirements, the effect of processing feedstuffs, and stress factors. He reviews the availability of nutrients in grains, distillers' grain residues, oilseed meals, molasses, silages, pastures, crop residues, and aquatic plants. Growth stimulants, nutritional management of ruminants in feedlots and pastures, and the value of feed additives are also among the topics considered.The scope of coverage provided by this volume will make it the leading reference for teachers, researchers, consultants, livestock producers, feed manufacturers, and all others who are involved in ruminant feeding and nutrition.From the Preface: This volume covers research on various nitrogen and energy feedstuffs and defines terminology commonly utilized in nitrogen and energy nutrition. The utilization of nitrogen and energy in oilseed meals, fish meals, cereal grains, distillers' residues, molasses, silages, grasses, hays, crop residues, animal waste, and nonprotein nitrogen sources is discussed. Details are given on development and utilization of net energy systems, systems for balancing total nitrogen, and nonprotein nitrogen with total digestible nutrients (TDN) or energy components of ruminant diets. Discussions are presented on metabolism, feedlot, milking, and grazing trials. Growth stimulants, processing of feedstuffs, type of animal, and environmental and management factors that affect feed intake, growth, feed efficiency, and quality of product are reviewed.Emphasis is given to the contributions of ruminal microbes in upgrading forage and nonprotein nitrogen sources to higher-quality bacterial protein, as well as their ability to downgrade high-quality protein and waste nitrogen when protein is fed in excess of microbial needs. Research is presented on means to increase bypassing of the rumen to prevent nitrogen wastage when ruminants are fed concentrate diets. Contributions of ruminal microbes in utilizing cellulosic materials as lignocellulose and hemicellulose as well as starch and other carbohydrates are discussed.

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.

Download or read book Nitrogen Fixation written by and published by BoD – Books on Demand. This book was released on 2020-04-08 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF), the process by which gaseous N2 is converted into ammonia (NH3) via the enzyme nitrogenase, is crucial for the availability of nitrogen (N) in the terrestrial ecosystem. Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only mimicked on an industrial scale by a chemical process. This microbiological process converts atmospheric nitrogen into a plant-usable form, thus decreasing the need to use chemical fertilizers in crop production. Chapters in this volume cover different aspects of this fantastic phenomenon, including biofertilizer, organic nitrogen in agricultural systems, nitrogen fertilization for sustainable crop production, and others. This book is designed for researchers, students and general readers.
