Download or read book Mitigation of Greenhouse Gas Emissions in Livestock Production written by Pierre J. Gerber and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Download or read book Estimation of Microbial Protein Supply in Ruminants Using Urinary Purine Derivatives written by Harinder P.S. Makkar and published by Springer Science & Business Media. This book was released on 2013-06-05 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has a long history of coordinating isotope aided research projects for improving animal productivity in developing countries. These projects have focused on enhancing the efficiency of animal production through better use of locally available feed resources and those that do not compete with human food. As a part of these efforts, the Joint Division has been actively involved in developing and simplifying approaches for measuring microbial protein supply to ruminant livestock. The contribution of microbial protein in meeting the overall requirement for protein in ruminants is significant, but understanding the contribution of microbial protein to the nutrition of ruminant livestock has been hampered by the lack of simple and accurate methods for measuring microbial protein production in vivo. A Consultants’ Meeting was held in 1995 in Vienna to explore the feasibility of using nuclear and related techniques to develop and validate new approaches for measuring microbial protein supply in ruminant animals. Based on the available information, the consultants considered that the purine derivative excretion method, which is non-invasive and both simple to use and inexpensive compared with other available methods, had the potential for use in developing countries. However, development of models for various animal species and breeds and their validation were required before this technique could be advocated for use.
Download or read book NorFor written by Harald Volden and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.

Download or read book Energy Nutrition in Ruminants written by E.R. Orskov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour 'in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Preface absorption and metabolism of the end-products of fermentation and digestion, together with estimates of digestive capacity in various segments of the gut. The ruminant's requirements for energy-yielding nutrients is considered in relation to the per formance of various activities and to environmental conditions, particular attention being paid to the requirement for glucose precursors.
