This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent times there has been much concern among animal product consumers about the safety and use of antimicrobial substances in the production of food for human consumption. This has been driven by the ban of the use of antibiotics at subtherapeutic levels for food animal production in Europe. For this reason, producers are always looking at 'natural alternatives to antibiotics to improve production from their animals. One such alternative is the use of yeast cultures of Saccharomyces cerevisiae in ruminant diets to manipulate rumen fermentation. Yeast culture fed to ruminants has increased production from beef and dairy cattle and sheep as well as stabilizing rumen fermentation under conditions such as rumen acidosis. Yeast culture has been shown to increase the microbial protein supply from the rumen by stimulating growth of bacteria in the rumen. Yeast culture may be used to alleviate the negative effects of rumen antimicrobials such as monensin on rumen microbial populations and fibre digestion. Four separate sets of experiments were undertaken. In the first set of experiments, the effects of 10 specific yeast cultures on the growth of 3 selected rumen bacteria was evaluated. The rumen bacteria evaluated were Ruminococcus albus, Selenomonas ruminantium and Ruminobacter amylophilus. It was found that only two of the ten strains of yeast tested were able to consistently decrease the lag time of the selected rumen bacteria. In the second set of experiments, the effects of yeast culture addition on a rumen fluid based batch culture fermentation was analysed by measuring the gas pressure produced by the fermentation. The results obtained were too variable to draw any conclusions from the data. In the third set of experiments, the effects of yeast, monensin and their combination were evaluated in rumen simulating continuous cultures. It was found that monensin increased the efficiency of the fermentation but decreased the total anaerobic bacteria. Yeast culture increased the total anaerobic bacteria. UNI yeast alleviated the reduction in anaerobic bacteria when combined with monensin. The last set of experiments were an attempt to develop an assay to measure the potential of certain yeast strains to stimulate rumen fermentation. The potential assays were based on the ability of yeasts to stimulate a growing culture of Ruminococcus albus. None of the assays attempted showed obvious potential as a future assay. From the study it seems that yeasts stimulate the growth of certain species of ruminal bacteria but not all yeast strains are able to do so. Yeast supplementation may be fed in combination with monensin in order to reduce the impact of monensin on the microbial populations of the rumen.

This book was released on 2023-07-04 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses a global issue of increasing high quality food from ruminant animals while reducing their impacts on the environment. However, one of the main constraints to livestock development and the underlying cause of the low productivity in many developing countries is inadequate nutrition associated with inefficient utilization of forages and fibrous feed resources. In many countries, fibrous feed makes up the bulk of available feed resource base, which is characterized by scarcity and fluctuating supply in the quantity and quality of feed resources, nutrient imbalance as seen in many native pastures, grasslands and crop residues-based feeding systems with limited use of commercial concentrate feeds such as soybean, cottonseed and groundnut meals, etc. Furthermore, the production of methane, an important greenhouse gas (GHG), from ruminants fed highly fibrous diets such as straws and stover is higher than those animals fed better quality forages or concentrate diets. Recent research shows that supplementing livestock diets with exogenous fibre degrading enzymes can improve feed utilization by enhancing intake, fibre degradation in the rumen and overall digestibility of fibrous feeds which in turn leads to improved animal performance, farmers’ income, and a reduction in GHG emissions. The book editors would like to acknowledge the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture for funding part of the studies that make up some of these chapters and were part of the final reports of a coordinated research project financed by IAEA.

Download or read book Climate Change Impact on Livestock Adaptation and Mitigation written by Veerasamy Sejian and published by Springer. This book was released on 2015-03-31 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses in detail both livestock’s role in climate change and the impacts of climate change on livestock production and reproduction. Apart from these cardinal principles of climate change and livestock production, this volume also examines the various strategies used to mitigate livestock-related GHG emissions, and those which can reduce the impacts of climate change on livestock production and reproduction. Presenting information and case studies collected and analyzed by professionals working in diversified ecological zones, the book explores the influence of climate change on livestock production across the globe. The most significant feature of this book is that it addresses in detail the different adaptation strategies and identifies targets for different stakeholders in connection with climate change and livestock production. Further, it puts forward development plans that will allow the livestock industries to cope with current climate changes and strategies that will mitigate the effects by 2025. Lastly, it provides researchers and policymakers several researchable priorities to help develop economically viable solutions for livestock production with less GHG emissions, promoting a cleaner environment in which human beings and livestock can live in harmony without adverse effects on productivity. Given that livestock production systems are sensitive to climate change and at the same are themselves a contributor to the phenomenon, climate change has the potential to pose an increasingly formidable challenge to the development of the livestock sector. However, there is a dearth of scientific information on adapting livestock production to the changing climate; as such, well-founded reference material on sustaining livestock production systems under the changing climate scenarios in different agro-ecological zones of the world is essential. By methodically and extensively addressing all aspects of climate change and livestock production, this volume offers a valuable tool for understanding the hidden intricacies of climatic stress and its influence on livestock production.
