View Rights PortalThis 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.
Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts it marks the end of a first phase of collaborative research on "Balanced Nutrient Management Systems for the Moist Savanna and Humid Forest Zones of Africa" and concludes with recommendations, providing essential reading for crop and soil scientists.
This work discusses the nutrient requirements of all forms of ruminant livestock.

This book provides a unique, complete coverage of current information on nutrient requirements, feed formulations and feeding practices of commercially important aquaculture species cultured around the world. Each chapter contains detailed feeding information on specific species and is written by an expert nutritionist on that species. The book is of interest to those working professionally in the industry, graduate level students and researchers.
This book describes current research in modelling nutrient use in farm animals, from cellular to ecosystem level. The chapters are developed from papers presented at a satellite meeting of the 9th International Symposium on Ruminant Physiology, held in South Africa in October 1999.Excellent papers from a top list of contributorsEditors of great reputationCovers the current topics of interest
As accelerated urbanization widens the gap between rich and poor and population growth becomes a global phenomenon, key strategies promoting rural economic development need to be implemented. This book covers the progress of a development initiative in Madagascar that enabled a region suffering from chronic drought and famine to provide food and become the area's breadbasket. Working with local people, the project delivered increased new cultivations, abundant harvests and improvements in infrastructure, media access, education and health. This is an indispensable book for development practitioners, NGOs, farmer associations and students in rural economics and related subjects.
Organic poultry production has increased significantly in recent years to keep up with increasing consumer demand for organic eggs and meat. There are many guidelines and restrictions on what should go into the feed of organically-farmed poultry, from which difficulties arise when trying to ensure a well-balanced nutritious diet without the use of any unapproved supplements. This, the second edition of Robert Blair's classic and bestselling book on the nutrition and feeding of organic poultry, presents advice for organic producers, and the agencies and organizations serving them. It covers: - Selecting suitable ingredients. - Preparing appropriate feed mixtures and integrating them into organic poultry production systems. - International standards for organic feeding. - Breeds that are most suitable for organic farming. - Examples of diets formulated to organic standards. Completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, this new edition also includes up-to-date information on the nutritional requirements of poultry and feed-related disease incidence in organic flocks. Also including the feasibility of utilizing novel feed, such as insect meal, and their acceptability by consumers of organic meat products, this book forms a comprehensive reference for students, organic farmers, veterinarians and researchers.

This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.
This report reviews the energy and protein requirement systems for dairy cows currently used in Britain and presents a new approach, along with the outline of a model for its implementation. Current systems give little consideration to the responses of the animal to changes in the nutrient supply, or to interactions between dietary constituents in their effects on digestion and metabolism. Neither do they predict any effect on the partition of nutrient use between milk and body, or changes in the yields of milk fat, protein and lactose, which determine the commercial value of the milk. Therefore the systems, although not inaccurate, lack relevance to the current needs of UK milk producers. Models which embody concepts of nutrient supply and utilization are reviewed and their development as viable alternatives is considered. It is concluded that a new diet formulation system for dairy cows should aim to predict voluntary feed intake, the partition of nutrient use between milk production and tissue deposition, and the short and long-term of effects of nutrition on fat, protein and lactose yields. The physical and biological characteristics of the cow must also be recognized and incorporated into any model for response prediction. The report is also published in Nutrition Abstracts and Reviews - Series B: Livestock Feeds and Feeding. It is an authoritative review for advanced students, research workers and advisors in animal nutrition and in dairy science and technology.
Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.
While information on the roles and regulation of transporters for all major nutrients and metabolites in plants has increased significantly, a synthesis of this research has been lacking. Based on current research in genomics and proteomics, this book clarifies the identification and characterization of plant membrane and vacuolar transporters. Transporter functions such as mineral nutrition, cell homeostasis, storage and stress responses are examined with a focus on enhancing nutrient use efficiency in crops, and increasing crops’ ability to withstand nutrient stresses and improve nutrient storage.
The livelihoods of millions of people in developing countries, which depend on dryland agriculture to ensure their food security and their well-being, could be improved measurably by gains in agricultural crop yields. This book describes lessons learnt from an innovative scheme in India that improved crop yields in drylands. It shows how the scheme can be scaled up for other dryland regions of the world. The scheme uses localized soil nutrient analyses to create an integrated, climate smart fertilizer and planting plan that maximises yields for farmers. This book describes how a partnership between a global scientific organization (such as International Crops Research Institute for the Semi-Arid Tropics, ICRISAT) and state and non-state actors can provide a route to equitable growth, specifically for small and marginal farmers, and how this approach can be replicated worldwide to enhance rural livelihoods. This strategic collaboration and its conceptual and functional design is fully outlined, as well as the scheme's implementation and the effective monitoring and learning process that has been created. ; This book describes lessons learnt from an innovative scheme in India that improved yields in drylands.
