        Nutrition and Feeding Organic Cattle

        by Robert Blair

        Organic cattle farming is on the increase, with consumer demand for organic milk and meat growing yearly. Beginning with an overview of the aims and principles behind organic cattle production, this book presents extensive information about how to feed cattle so that the milk and meat produced meet organic standards, and provides a comprehensive summary of ruminant digestive processes and nutrition. Since the publication of the first edition, global consumers have increasingly become concerned with the sustainability of meat production. Here, Robert Blair considers the interrelationships of sustainable practices and profitability of organic herds, reviewing how to improve forage production and quality, and minimizing the need for supplementary feeding using off-farm ingredients. This new edition also covers: - Managing a recurrent shortage of organic feed ingredients, due to increased GM feed crop cultivation worldwide - Current findings on appropriate breeds and grazing systems for forage-based organic production - Diet-related health issues in organic herds and the effects of organic production on meat and milk quality. Required reading for animal science researchers, advisory personnel that service the organic milk and beef industries and students interested in organic milk and meat production, this book is also a useful resource for organic farming associations, veterinarians, and feed and food industry personnel.

        Evidence Based Equine Nutrition

        A Practical Approach For Professionals

        by Teresa Hollands, Lizzie Drury

        This book uniquely provides both the scientific basis of equine nutrition and the translation of that science into practical, day-to-day feeding advice. It summarises the latest research to provide readers with the evidence base needed to both confidently advise those who want to understand the science behind equine nutrition, and apply that evidence into practical advice for anyone who just wants to know how to feed horses. Both veterinary and animal science courses struggle to provide adequate nutrition training within their syllabuses. Much of the general information available is poorly explained and not evidence based. This book fills that gap, with the author team relaying over 50 cumulative years' experience teaching equine nutrition to both practising clinicians and students. Find answers to the most common queries and challenges encountered during nutritional consultations across 17 informative chapters, using typical case-based examples as experienced by the authors. Fully supported throughout with visual aids and photographic illustrations, they show how to easily increase compliance and understanding. Key topics covered include: How to take a diet history, including which forage and concentrates are most appropriate, and how to interpret the information on feed labels; How to take the horse's history, including workload, body weight and body fat scoring; Supporting achievable and sustainable fat loss in overweight horses; Appropriate rations across a range of performance disciplines and for breeding horses; Appropriate feeds and supplements for competition, including how to recognise potential hazards, signs of quality and issues of feed safety; How to use ration programmes, including a range of frequently asked questions for horses with specific nutritional requirements from allergies to obesity. A recommended resource to support the teaching of veterinary nutrition, this book should also be found on the bookshelf of all veterinarians, animal scientists, trainers, nutritionists, and nutritional advisors. This book includes forewords by Carl Lester, Honorary Fellow of the British Horse Society and recipient of an MBE for his services to Equestrianism, and Tim Mair, former President of the British Equine Veterinary Association.

        Plant Nutrition, Second Edition

        by Alex C. Wiedenhoeft, Series Editor: William G. Hopkins

        The mineral nutrients of plants play key roles in plant growth and development, forming the underpinnings of the past, present, and future of agriculture. Plants with insufficient nutrients exhibit symptoms of sickness that can be confused with infectious plant diseases. The nutrients needed by plants are taken from the soil by the roots, and in many plants, the roots also form associations with other organisms that help them more efficiently colonize the soil or provide nutrients to the plant. All facets of plant nutrition, from the effect of nutrients on the plant to the role of plants in the global cycling of nutrients, impact the ways in which humans use and depend on plants for most aspects of our existence. Plant Nutrition, Second Edition addresses the basic chemistry, biology, physiology, and ecology of plant nutrition and shows how these topics relate to humans on a personal, social, and global scale.

        An Interprofessional Approach to Veterinary Nutrition

        by Rachel Lumbis, Tierney Kinnison

        In veterinary practice, the interface between veterinarians, veterinary nurses or technicians, and paraprofessional team members is crucial. It influences patient care, the incidence of medical errors, client satisfaction, the success of the veterinary practice and revenue generation. Ensuring a coherent approach to the maintenance of the animal health and wellbeing is of paramount importance, yet challenges such as interprofessional prejudice, contrasting motivations, and a lack of recognition, respect, empowerment or trust, can prevent best practice. Nutrition is one of the most important considerations in the maintenance of health, and plays a critical role in disease management, patient recovery and hospital outcome. Owners are increasingly aware of nutrition's role in optimising pet health, yet considerable misinformation can make this one of the most difficult aspects of pet ownership. Playing a central role as a source of expert information, the veterinary healthcare team must rise to the challenge of optimising pet nutrition. This book: - Provides evidence-based theory in an accessible and practical way to help veterinary healthcare teams implement interprofessional approaches to nutritional care and support; - Demonstrates how robust interprofessional practice and teamwork help to overcome challenges; - Emphasises collaborative working across the healthcare team. With effective interprofessional communication and collaboration considered a key factor in the successful implementation of nutritional assessment, forming a positive team environment founded on respect, trust and mutual support helps to overcome challenges and provide the best outcome for both pets and their owners.

        Plant Invasions

        The Role of Biotic Interactions

        by Anna Traveset, David M Richardson

        Despite many books on plant invasions, none has focused on the role of species interactions. This book is a comprehensive overview of how plant invasions are mediated by varied species interactions and how such invasions influence this important component of biodiversity which involves the interactions (the 'glue') among a community's species. Besides highlighting relevant findings, the book digs deeply into new methodologies to understand species interactions in plant invasions and how this can improve management of invaded communities. The book covers: - Main theories/hypotheses in plant invasion ecology that invoke species interactions - Plant invasions promoted by mutualistic interactions and release from enemies - Antagonistic interactions preventing or hindering plant invasions - Consequences of plant invasions on native species interactions and ecosystem functioning - The interaction network approach to understanding plant invasions - Importance of considering species interactions in managing plant invasions Future avenues of research are highlighted in a final chapter. Table of contents Part I: Background Chapter 1: Plant invasions: the role of biotic interactions – An overview Chapter 2: The role of biotic interactions in invasion ecology: theories and hypotheses Part II: Positive and negative interactions in the soil Chapter 3: Soil biota and non-native plant invasions Part III: Mutualistic interactions that promote plant invasions Chapter 4: Pollination interactions promoting plant invasions- Chapter 5: Seed dispersal interactions promoting plant invasions Chapter 6: Ungulates as dispersal vectors of non-native plants Chapter 7: The role of plant-plant facilitation in non-native plant invasions Chapter 8: How direct and indirect non-native interactions can promote plant invasions, lead to invasional meltdown, and inform management decisions Part IV: Antagonistic interactions that hinder plant invasions Chapter 9: Biotic resistance to plant invasions Chapter 10: EICA 2.0: A general model of enemy release and defence in plant and animal invasions Chapter 11: The role of pathogens in plant invasions Chapter 12: Direct and indirect effects of herbivores influencing plant invasions Part V: Consequences of plant invasions for biotic interactions among native species Chapter 13: Impacts of non-native plants on plant-pollinator interactions Chapter 14: The effect of non-native plant invasions on seed dispersal of native plants Chapter 15: Allelopathic disruptions of biotic interactions due to non-native plants Chapter 16: Competition between native and non-native plants Chapter 17: Indirect biotic interactions between non-native plants and native plants and animals Part VI: Novel techniques and experimental approaches in the study of plant invasions Chapter 18: How a network approach has advanced the field of plant invasion ecology Chapter 19: Molecular ecology of plant-microbial interactions during invasions: progress and challenges Part VII: Biotic interactions and the management of ecosystems invaded by non-native plants Chapter 20: How can progress in the understanding of antagonistic interactions be applied to improve biological control of plant invasions?

        History and Future of Plants, Planet and People

        Towards a New Ecologically Sustainable Age in People’s Relationships With Plants

        by Alan Hamilton, Pei Shengji

        This fascinating book presents the experiences and pooled knowledge of two very different conservation scientists; Pei Shengji from Sichuan, China and Alan Hamilton from London, UK. They have been drawn together over many years through working on some of the same conservation projects and have discovered that they overlap in their ideas about the sorts of work that needs to be done and how it can best be carried out. The book describes some of their own experiences, set within the contexts of their varied careers and the development of their thinking. Plant conservation is crucial to the preservation of natural ecosystems, but conventional approaches have met with only limited success. The authors have concluded that plant conservationists need social allies - elements of society that have other primary concerns, but whose efforts, if successful, will bring benefits to plant conservation too. It is the state and condition of plants on the ground that ultimately matter in conserving ecosystems, and therefore it is the role of local people who interact directly with them which enables success. Ethnobotany is a key skill required of practical plant conservationists. Its techniques enable them to explore connections between people and plants, learn about local perspectives and establish relationships with the people upon whom conservation and sustainable development relies. This book: recommends how to advance plant conservation, based on real experiences. will inspire more people to become involved in plant conservation. demonstrates how the very different backgrounds of the authors have influenced the courses of their careers, but have enabled them to come to very similar conclusions about conservation practice. demonstrates the importance of geographically-based biocultural diversity, as a counterbalancing force to globalisation.

        Plant Clinic Handbook

        by Jim M Waller, B J Ritchie, Mark Holderness

        Since its creation in 1920, The International Mycological Institute has been concerned with the identification of plant-pathogenic fungi and bacteria. Part of its role has been the development of plant clinics, which have an important role in providing access for farmers and extension workers to specialist scientific services for the diagnosis of plant disease problems and advice on control measures. Clinics can also be bases from which surveys of crop problems are made and data on the needs of farmers are assimilated, in order to identify research priorities. This practical handbook provides information on all aspects of the technical procedures, material requirements and organisation for the effective operation of a plant clinic. It describes the diagnostic process, from field observation and collection through to methods of culture, microscopy, keeping records and reference material, general laboratory practice and equipment maintainance. The procedures described have been used successfully at IMI for many years, and through a series of training programmes, have been transferred to laboratories in many other countries. Essential reading for those involved in setting up and running plant clinics and plant quarantine facilities, this handbook will also be of interest to all practitioners and advanced students of plant pathology, particularly those concerned with diagnostics, and to crop protection specialists working in an advisory capacity.
