Energy and Protein Metabolism and Nutrition is of increasing importance as greater efficiency and health benefits are sought in feed for animal production. Top scientists from around the world have collaborated in this book to exchange expertise and knowledge on the latest developments in the field. The topics range from tissue metabolism and regulation mechanisms to practical aspects of energy and protein nutrition and feeding. A better and deeper understanding of nutrient metabolism and nutrition can only be achieved by integrating the outcomes of scientists researching different aspects of this topic. In doing this practical outcomes are sought for the direct benefit of producers and consumers. Special topics such as the links between energy/protein metabolism and nutrition regarding food quality, nutrigenomics, environmental sustainability and animal welfare in relation to the topic are all explored. This book is a valuable resource to all researchers and industry professionals who concern themselves with animal nutrition.
The objective of this book is to provide a scientific-based, multidisciplinary perspective to the dialogue between society and the stakeholders within livestock production. Concerns and problems related to food safety, animal welfare and rural environment are discussed within a holistic approach. This unique approach has an added-value compared to other books which cover these topics from a specialist point of view. The different issues are developed by well-known experts in their field of work. They are dealing with the latest developments in livestock production in relation to social concerns (such as, regulations, risk communication, reduction of environmental impact, sustainability and economic and social impacts of alternative strategies) and production systems (including transport and slaughter, feeding strategies, waste management and future monitoring technology).Readers from various disciplines will find these ideas useful and complimentary to their own expertise, and may apply them to decision making, vocational training and other educational applications.
For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has m...
Crop, livestock, and forestry productions systems are important sources and sinks of greenhouses gases, but estimates of the magnitude of gas fluxes are more uncertain than those for other economic sectors such as transportation and electricity generation. Recent improvements in process-level un-derstanding, modeling software, and observational data used for model testing have increased the accuracy of model predictions, but substantial uncertainty remains, particularly regarding the potential for different management practices to mitigate emissions. The chapters in this volume demonstrate that both simple methods and complex models have strengths and limitations depending on stake-holder interest, scale of application, and other factors. Future improvement can be facilitated by or-ganizing model input and testing data into web-accessible databases and by making model algorithms more available and transparent.
Development in agricultural sciences, particularly in farm animal sciences, resulted in the increased productivity to meet the demand for high quality and relatively cheap protein sources for human nutrition. In parallel, this increased productivity challenges the adequate supply of nutrients, including protein and energy, needed to cover not only high performances, but also insure animal health and welfare, reproduction and quality of products in a sustainable environment. The precise understanding of the animal biology is crucial for animal health and welfare, sustainable animal production, and health of animal product consumers. This book focuses on combining basic and applied research an...
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 produ...
In order to meet increasing global demand for meat and animal by-products increasingly intensive animal production is necessary. Creating a sustainable system in animal agriculture that works in different production environments is a major challenge for animal scientists. This book draws together themes on sustainability that have emerged as the most pressing in recent years. Addressing practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues, animal welfare concerns, societal impacts and an analysis of the data used to assess the economic sustainability of farms.
The book combines information about the behaviour that allowed ruminants to survive and to evolve on Earth: the rumen. Furthermore, the reader will find aspects involving rumen anatomy, physiology, microbiology, fermentation, metabolism, manipulation, kinetics and modeling. Thus, the book was not only organized to help students involved in areas such as ruminant nutrition and ruminant production but collegians gathering material for teaching practices.
This book brings together the papers presented orally or as posters at the Sixth International Workshopon Modelling Nutrient Utilization in Farm Animals, held in Wageningen, The Netherlands, 6 - 8 September2004. The purpose of this book is to present current research in modelling nutrient digestion andutilization in cattle, sheep, pigs, poultry and fish.The book is organised into six sections that cover a range of topics and modelling approaches; theseare (i) absorption and passage; (ii) growth and development; (iii) mineral metabolism; (iv) methodology;(v) environmental impact; and (vi) animal production and feed evaluation. Deterministic, stochastic,empirical and mechanistic modelling approaches are described.This book will be of significant interest to researchers and students of animal science, particularly thoseconcerned with nutrition modelling.
Addressing methane emissions from livestock and rice systems is vital for promoting sustainable agriculture and mitigating climate change. This FAO report comprehensively addresses methane emissions in agriculture and their impact on global greenhouse gas levels. By analysing sources, sinks, quantification methods, and mitigation strategies, this publication highlights challenges and opportunities to reduce methane emissions from livestock and rice production systems.
