This book is the first veterinary textbook dedicated to nursing care plans. It offers a broad overview of the theory and practice of care planning in veterinary nursing, answering three key questions: What are nursing care plans? Why should nursing care plans be used in practice? How should nursing care plans be used in practice? Author Helen Ballantyne provides basic definitions and explanations which will be useful to those unfamiliar with nursing care plans. For those veterinary nurses and technicians who are using nursing care plans, the content stimulates debate and discussion, by covering some of the philosophical and theoretical aspects of nursing and drawing comparisons and contrasts between the veterinary and human nursing roles and contexts. There is a pressing need for veterinary nurses to establish themselves as professionals and develop their unique role within the veterinary care team. Nursing care plans are a core tool to support that development. It is hoped that veterinary nurses may borrow tools from the pages of this book or use it as a resource design their unique care plans: either way, this practical guide will support the application of care planning, no matter the species of the animal kingdom for whom you are caring.

DIRECTLY APPLIES TO LIFE ON LAND SDG and CLIMATE CHANGE SDG. International organizations such as the Intergovernmental Panel on Climate Change (IPPC), World Health Organization, Food and Agriculture Organization and World Organization for Animal Health have all reminded us that health impacts of climate change will become some of societies' greatest challenges. How we respond or adapt to climate change will have profound implications for people, animals, biodiversity, economies and ecosystems today as well as in the future. The book provides, in one easy reference, all of the information Animal Health practitioners need from defining the climate change concept, providing science-based evidence of climate change degradation of animal (ecosystem) health and successful mitigation and reversal strategies. Despite being arguably the most important challenges of the 21st century, engagement, and leadership from the animal health sector on climate change remains hard to find. This book attempts to support animal health professionals by providing information, knowledge, and experiences they can use to remedy this situation. There is no other book that covers anything like the proposed subject matter to this level of completeness and detail. The publishing of a text of this nature could help erode the power of the climate denialism lobby, shifting the debate and allowing mitigation efforts to gain higher priority. The tone of the book has an understated sense of urgency, leaning slightly toward presenting as a 'Manual for the apocalypse'. This has potential to be a benchmark publication. The text not only defines climate change but takes a proactive approach with intervention and corrective action examples: each chapter ends with suggestions on teachable and actionable ideas that could be used to mobilize concepts and information provided into education or advocacy. In this way, the book not only brings key ideas, principles and information to understand the implications for climate change for animal health, but will help translate the book's offerings into education and intervention. Teachers and researchers could use this one-of-a-kind book to frame a course or seminar series heightening student career engagement and stewardship of a more sustainable and healthier planet.

Equitation Science together with classical riding is today probably the most humane, effective, and practical way of training and enjoying the horse, competitive or not. To avoid getting involved is to accede to the status quo. Our horses deserve better.~Sharon E. Cregier, Ph.D., FIASH (Hon., Edin.), founding member of Equine Behaviour Forum In precise, practical language, Fine Riding describes how to blend the principles of classical riding with the modern findings of Equitation Science, demonstrating how to put the principles into practice when training and riding horses. The book encompasses the author's lifelong background in authentic classical riding and a 17-year study and practice of Equitation Science. It presents the best of the old with the best of the new, resulting in a unique and rational blend of principles, clearly explained, that enables and encourages readers to train, ride and care for their horses truly effectively and humanely. Applicable to riding of all schools of thought, from hacking to racing, including jumping, McBane's method is more than simply another 'system' of riding. It applies the results of rigorous scientific studies to the historical, classical training and riding of horses in an ethical, humane and effective way, explaining the principles in such a way that readers will feel able to put it into effect themselves. This book will encourage horse owners to serve their horses with renewed understanding and commitment.

This book is the first photographic and descriptive musculoskeletal atlas of Hylobates, and adopts the same format as the photographic atlas of Gorilla published by the same authors in 2010. These two books are part of a series of monographs that will set out the comparative and phylogenetic context of the gross anatomy and evolutionary history of the soft tissue morphology of modern humans and their closest relatives. This atlas, which includes detailed high-quality photographs of musculoskeletal structures from most anatomical regions of the body as well as textual information about the attachments, innervation and weight of the respective muscles, is based on dissections and on an extensive review of the literature. It provides an updated review of the anatomical variations within hylobatids as well as an extensive list of the synonyms used in the literature to designate the structures we discuss. The atlas will be of interest to students, teachers and researchers studying primatology, comparative anatomy, functional morphology, zoology, and physical anthropology and to medical students, doctors and researchers who are curious about the origin, evolution, homology and variations of the musculoskeletal structures of modern humans.

1) The first and only textbook solely about public health entomology, mapping onto new Certificate in Public Health Entomology courses in the U.S. Half the price of the nearest competitors, with the subject of Public Health Entomology rapidly becoming a hot topic in public health, this should be adopted as the "go-to" text for public health entomology. 2) Discusses the rationale for having public health entomology programs in state and federal health agencies. 3) Shows how to set up a public health program from scratch. 4) Compares and contrasts specific duties of a public health entomologist (and what are NOT the duties). 5) Includes a section about the primary public health arthropod vectors, their biology, distribution, disease potential, and control.

We are surrounded by thousands of animals, alive and dead. They are an intimate and ever-present part of our human lives. As a society, we privilege veterinarians as experts on these animals: they are our educators and teachers in what they say, what they do, and the decisions that they make. Yet, within the field of education, there is little research on the curriculum, pedagogy, and experiences of veterinary school and students. What do veterinarians learn in veterinary school? How do their experiences during those four years shape their perceptions of animals? How do the structures, curriculum, and pedagogy of veterinary college create and influence these experiences? Learning Animals opens up this conversation through an exploration of the complicated, fascinating and often painful stories of a cohort of veterinary students as they make their four-year journey from matriculation through graduation. The book examines how the experiences of veterinary students shape how humans relate to animals, from public policy and decision-making about the environment and animals slaughtered for food, to the most personal decisions about euthanizing companion animals. The first full-length, critical, qualitative study of the perspectives of our primary teachers about animals, this will be a thought-provoking read for those in the fields of both educational research and veterinary education.

Livestock Ration Formulation for Dairy Cattle and Buffalo provides an interdisciplinary, integrative perspective and optimization on dairy cattle feed formulation problem solving. It helps dairy farmers by introducing them the right frequency and right amount of balanced diet to be fed to cattle's and buffaloes at different body condition so that their feeding cost should be decreased and there should be increase in income for dairy farmers, as they don't have enough knowledge of feeding practice. It helps animal nutritionist to work for dairy farmers which have very limited feed resources to fulfil nutrients requirement in terms of crude protein (CP), total digestible nutrient (TDN), calcium (Ca) and phosphorus (P) by developing a software programme to plan a balanced low budget diet. It includes the Linear and Goal programming model for non-pregnant dairy buffalo is been solved using Hybrid Real Coded Genetic Algorithm and the results are compared with Real Coded Genetic Algorithm (RGA) considering different versions like RGA without crossover, RGA without Mutation, RGA with crossover and mutation. These models can also be applied with other nutritional models like CNCPS, INRA. This book is a step forward in that direction to provide least cost diet formulation based on nutrient requirement of the cattle and buffalo, which is been calculated according to Indian Council of Agricultural Research (ICAR, 2013) and NRC (2001) on dry matter basis, provides a clear and precise platform for other researcher in Animal Nutrition field which also give initial platform to build a software and android application to formulate least cost ration Based on data and algorithm used in this book, which helps Dairy farmers directly to feed balanced diet at cheap rate. Features: It is a good reference to local dairy farmers by introducing them to the right frequency and right amount of balanced diet to be fed to cattle and buffaloes at different production cycles. It will provide basic platform and some solutions to built-up software about cattle nutrition development and least cost formulation for end-user. It has several techniques for optimizing animal diet formulation but a good balance between coding/programming and animal nutrition is incorporated towards application of soft computing technique to improve the quality of the solution due to rigidity of the constraints.

The common fruit fly - Drosophila melanogaster - has been the subject of genetics research since the early twentieth century. The complete genomic sequence of Drosophila was published in 2000 and it is still the model organism par excellence for the experimental study of biological phenomena and processes. It is also by far the best model for studying gene function in mammals, including humans. Presenting state-of-the-art studies on the behaviour of Drosophila, this volume discusses normal and pathological models of neurobehavioral disorders and encompasses the specialised methods that have been used, from anatomical, histological, immunohistological and neurophysiological to genomic, genetic and behavioural assays. A comprehensive and thorough reference, this volume is a valuable resource for students and researchers alike across several disciplines of life sciences, including behavioral genetics, neurogenetics, behavioral neuroscience, molecular biology, evolutionary biology and population biology.

Organized by body system, the new edition of this highly illustrated textbook covers the normal histological appearance of tissues in a wide range of animals, both domestic and exotic species, with relevant clinical correlates emphasizing the need to appreciate the normal in order to recognize the abnormal. In this update by two experienced veterinary pathologists and histology lecturers, new species, such as other companion mammals, aquatic species and livestock, are introduced into each chapter along with a wealth of new high-quality images. A new chapter covers epitehlial tissue and new techniques used in histology and histopathology are discussed throughout, including ISH and digital image analysis. Pathogenesis explanation is introduced in the current (and many new) cases of histopathology. The breadth of coverage-farm animals, dogs, cats, horses, birds, reptiles, amphibians, and fish-and the integration of normal and abnormal tissue provide a reference of lasting value to veterinary students as well as veterinary practitioners and pathologists needing a quick refresher.

Addresses the common stressors and struggles of those in the veterinary profession with a focus on real life stories and academic research. Emphasizes practical ways to build a positive supportive culture within the profession, through self-care and building resilience. A 2018 study in the Journal of the American Veterinary Medical Association gathered more than three decades of data to show that veterinarians are up to 3.5 times more likely to die by suicide than members of the general population. Burnout, compassion fatigue and depression are major issues for the veterinary profession, and this book will help vets address these issues head-on and give them tools to overcome them. Existing books on compassion fatigue tend to be more prescriptive. This book offers a more humanistic perspective, sharing real-life stories to show how we all struggle with similar issues and that there are things we can do to help. It connects readers to the fact that we all struggle, we all suffer, and there is a way to manage your professional life and thrive.

The second edition of the book has sold over 3850 copies, making this our bestselling veterinary textbook. Day passed away in 2020 and Professor Brian Catchpole and Harm HogenEsch are the ideal authors to update this in his stead, actively teaching and researching in this field at the RVC, the UK's biggest veterinary college, and Purdue, a huge vet school in the US. The two new authors give this greater international coverage. The most accessible book on this topic for veterinary students: chapters are concise and informative, focused on the main message. It stands out among the competitor 'tomes' which are expensive and inaccessible, or are geared towards human (or mouse) immunology. In a nutshell, this book provides the essential immunological information specifically for vet students, but remains light and easy to read. Colour illustrations are effective, clear, simple and straight to the point, with nearly one illustration/schematic for each important section/paragraph. The clinical cases bring the material to life, while a short animation adds new practical application via the Support Materials tab on the Routledge website.

This is the first guide to Veterinary Narrative Medicine, a cutting-edge approach in human medicine with multiple applications in veterinary medicine. The text combines the latest research with numerous real-world examples and practical techniques to improve client communication, patient care, and veterinary well-being. Narrative Medicine maintains that a patient should be viewed as an individual rather than an example of a disease process, and that this can be accomplished by using narrative. This book explores methods and theories from leaders in the human Narrative Medicine field while addressing topics unique to veterinary medicine. Readers will gain tools to help navigate difficult conversations and situations in clinical practice, including those involving the end of life. Narrative Medicine in Veterinary Practice also addresses the important issue of veterinary wellness. The ability to view the veterinarian's own stories and those of clients and patients as narratives may help practitioners maintain both emotional and work-place boundaries as well as decrease burnout and compassion fatigue. The book describes basic techniques to promote self-reflection and mindfulness, skills often overlooked in the veterinary profession which can improve resilience and increase the enjoyment of veterinary practice. This is important reading for veterinary practitioners, students, veterinary nurses, technicians, social workers, and all veterinary clinic staff.

This guide is designed as an introduction to the basic methods for identifying mammal bones and teeth. It is intended to highlight for beginners the main points on which identifications can be made on the bulk of bones and teeth from a small range of common Old World mammals.

Health and welfare issues of brachycephalic (flat-faced) animals are one of the most pressing problems facing companion animals right now. Dogs, in particular, are suffering from a 'brachycephalic crisis' resulting from a perfect storm where predispositions to an array of health issues are amplified by a population boom for certain brachycephalic breeds such as the French Bulldog and Pug. But yet, for many owners, these dogs represent the perfect companion: endearing personas and cute looks in a socially desirable package. So where is the truth in all of this? This book will equip veterinary professionals, animal welfare scientists, breeders and owners with the fuller story about brachycephalic health and welfare. The first half of the book provides the context of how and why we are in this crisis, offering in-depth historical, social, ethical, communication, nursing, welfare, epidemiological, genetics and international perspectives. The second half shifts towards the clinical arena, with chapters that cover the background, diagnosis, treatment and prevention of the many unique healthcare needs of brachycephalic animals. Cutting-edge knowledge is shared on a range of disciplines including respiratory disease, ophthalmology, dermatology, dentistry, neurology, obesity, reproduction and anesthesia. With twenty chapters written by world-leading experts, lifetimes of experience and knowledge are condensed into the first book dedicated exclusively to brachycephaly in companion animals. This essential reference resource will inform, challenge and stimulate; it will open your mind to new opportunities for you to improve the welfare of brachycephalic animals by your personal and collective choices and actions. But prepare to be surprised: you may just find that your views on brachycephaly in companion animals will be changed forever.

The study of animal movement has always been a key element in ecological science, because it is inherently linked to critical processes that scale from individuals to populations and communities to ecosystems. Rapid improvements in biotelemetry data collection and processing technology have given rise to a variety of statistical methods for characterizing animal movement. The book serves as a comprehensive reference for the types of statistical models used to study individual-based animal movement. Animal Movement is an essential reference for wildlife biologists, quantitative ecologists, and statisticians who seek a deeper understanding of modern animal movement models. A wide variety of modeling approaches are reconciled in the book using a consistent notation. Models are organized into groups based on how they treat the underlying spatio-temporal process of movement. Connections among approaches are highlighted to allow the reader to form a broader view of animal movement analysis and its associations with traditional spatial and temporal statistical modeling. After an initial overview examining the role that animal movement plays in ecology, a primer on spatial and temporal statistics provides a solid foundation for the remainder of the book. Each subsequent chapter outlines a fundamental type of statistical model utilized in the contemporary analysis of telemetry data for animal movement inference. Descriptions begin with basic traditional forms and sequentially build up to general classes of models in each category. Important background and technical details for each class of model are provided, including spatial point process models, discrete-time dynamic models, and continuous-time stochastic process models. The book also covers the essential elements for how to accommodate multiple sources of uncertainty, such as location error and latent behavior states. In addition to thorough descriptions of animal movement models, differences and connections are also emphasized to provide a broader perspective of approaches.

Following succinct discussion of the relevant canine anatomy and physiology, the authors provide chapters on each of the key topics: movement and muscles; exercise; preparation for sports performance; rehabilitation techniques; massage and physical therapy; and common relevant pathologies affecting dogs. Physical Therapy and Massage for the Dog is of interest to all those involved in canine welfare including veterinary practitioners, veterinary students, therapists, dog owners and dog trainers.

This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42-47% of them are brooders. With 13,000 species, polychaetes are gonochores but some 207 species of them are hermaphrodites. Clitellates are all hermaphrodites; of them, 76 species are parthenogens, of which 56 are earthworms. Regenerative potency of annelids ranges from an organ to an entire worm from a single 'seminal' segment. The head, tail and both together can be regenerated 21, 42 and 20 times, respectively. However, the potency is limited to ~1% of polychaetes and < 2% of oligochaetes. In oligochaetes, the chloragogue temporally separates regeneration and reproduction but sedentary polychaetes undertake them together at the reduced reproductive output. Only 79 polychaete and 111 oligochaete species have the potency for clonal reproduction. Within families, the potency ranges from 2% in spionids to 54% in naidids. Epitoky, a spectacular and unique phenomenon, involves the transformation from benthic to meroplanktonic reproductive morphism. It occurs in 106 errant polychaete species. The larger glycerides, nereidids and eunicids use muscular energy to climb < 50 m vertical distance. But the small phyllodocids and cteniodrilids may reduce buoyancy to climb 1,000-4,000 m vertical distance. Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the 'brain' regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.
