Utilisation Of Grazed Grass In Temperate Animal Systems

Leading authorities from wide geographical regions of the globe will review the most up-to-date information in relation to temperate grasslands. Topics covered are: nutritive value of pasture; plant characteristics conducive to high animal intake and performance; modelling of both grass growth and animal production and intake in grazing systems; optimising financial returns from grazing; decision support systems; optimal animal breeds and traits for grazing systems; challenges and opportunities for animal production in the immediate future .In addition, short papers will present the most recent research on the above mentioned topics. One paper will present a comprehensive overview of animal production from pasture in Ireland This book will be of interest to grassland and ruminant production scientists, mathematical modellers working on grazing systems, extension workers, students of agriculture and animal production and progressive livestock farmers.

A detailed study of grasslands and the management and investigation of grazing systems for animal production. The twenty-one chapters have been written by internationally recognized experts from Australia, the USA, the United Kingdom and New Zealand, and cover four main areas of interest. The first group of chapters is concerned with the evolution and ecology of grasslands and the behaviour of grazing animals. The second group deals in considerable depth with the intake of food and the nutritional value of different kinds of grassland (tropical, temperate and mediterranean), covering the most important tame' pastures. Arctic and multiple-purpose grazing are then discussed with emphasis on the social factors governing the use of resources. The following nine chapters deal with animal production technologies and management, including forage crops, fertilizer use, supplements for grazing animals, drought, detrimental substances in plants, and computer modelling of grazing systems. The final chapter integrates all this information and discusses the management of grazing systems, including decisions about subjects such as stocking rate and subdivision.

This new, fully updated and revised edition of Improved Grassland Management covers all aspects of grassland management and is of particular relevance to the UK and the Republic of Ireland, although the principles discussed apply to all temperate grassland zones. Almost twenty years ago, when the original edition of this book was written by John Frame, issues such as efficiency in the use of nutrients in manures, grassland biodiversity and greenhouse gas emissions from ruminant production were either nascent, or of no relevance to mainstream grassland farming. The intervening two decades have seen the introduction of water and, latterly, air quality directives by the EU, cross compliance, the single farm payment, and an ever-increasing need for grassland farmers to be conscious of the economics of their business. The present edition, which has been thoroughly revised by Scott Laidlaw, covers the full scope of modern grassland management. Accordingly the application of technical developments in supplying and utilizing grass and forage, which remain central to grassland management, is presented in the context of these changes.Topics covered include: breeding and evaluation of new varieties of grass to meet current needs; new technology in establishing swards; legislative constraints, background science and practice in determining forage quality and the utilization of forage either for grazing or silage; feed budgeting, grassland biodiversity, grassland and climate change, and transferring knowledge and technology; wide-ranging list of sources and references, which provides the reader with further detailed information. Essential reading for all those involved in modern grassland management including grassland farmers, agricultural consultants and advisory officers, as well as agricultural, land use and biology students. Written in a reader-friendly advisory style, it can be read and understood without an in-depth technical or scientific background. Fully illustrated with 61 colour photographs.

Authored by international experts in the animal-production industry, this record of the proceedings of the 43rd University of Nottingham Feed Conference explores topics such as feed evaluation systems, the effects of fatty acids on fertility, and the interactions between nutrition, stress, and the immune system. Filled with comprehensive analyses of the issues as well as practical applications, this is an essential read for researchers, consultants, animal science students, legislators, and practitioners. The newest volume in the series, this detailed account contains the most recent information in the livestock industry.

This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.

This book is a printed edition of the Special Issue "Forage Plant Ecophysiology" that was published in Agriculture

Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.
