Book Description
The judging of merit in livestock is as fundamental to selection as selection is fundamental to improvement. The U.S. show ring has served to accelerate competitive progress among breeds, to unify opinion on useful type and to point out various improvement opportunities.

Book Description
Contests are an important aspect of the lives of diverse animals, from sea anemones competing for space on a rocky shore to fallow deer stags contending for access to females. Why do animals fight? What determines when fights stop and which contestant wins? Addressing fundamental questions on contest behaviour, this volume presents theoretical and empirical perspectives across a range of species. The historical development of contest research, the evolutionary theory of both dyadic and multiparty contests, and approaches to experimental design and data analysis are discussed in the first chapters. This is followed by reviews of research in key animal taxa, from the use of aerial displays and assessment rules in butterflies and the developmental biology of weapons in beetles, through to interstate warfare in humans. The final chapter considers future directions and applications of contest research, making this a comprehensive resource for both graduate students and researchers in the field.

Book Description
"Within a day of receiving this book, I had consumed it... Absorbing, moving, and compulsively readable."—Lydia Davis In this affectionate, heart-warming chronicle, Rosamund Young distills a lifetime of organic farming wisdom, describing the surprising personalities of her cows and other animals At her famous Kite's Nest Farm in Worcestershire, England, the cows (as well as sheep, hens, and pigs) all roam free. They make their own choices about rearing, grazing, and housing. Left to be themselves, the cows exhibit temperaments and interests as diverse as our own. "Fat Hat" prefers men to women; "Chippy Minton" refuses to sleep with muddy legs and always reports to the barn for grooming before bed; "Jake" has a thing for sniffing the carbon monoxide fumes of the Land Rover exhaust pipe; and "Gemima" greets all humans with an angry shake of the head and is fiercely independent. An organic farmer for decades, Young has an unaffected and homely voice. Her prose brims with genuine devotion to the wellbeing of animals. Most of us never apprehend the various inner lives animals possess, least of all those that we might eat. But Young has spent countless hours observing how these creatures love, play games, and form life-long friendships. She imparts hard-won wisdom about the both moral and real-world benefits of organic farming. (If preserving the dignity of animals isn't a good enough reason for you, consider how badly factory farming stunts the growth of animals, producing unhealthy and tasteless food.) This gorgeously-illustrated book, which includes an original introduction by the legendary British playwright Alan Bennett, is the summation of a life's work, and a delightful and moving tribute to the deep richness of animal sentience.

Book Description
"This is a delightful book, full of interesting aspects of animal welfare. An excellent guide to the academic study of animal welfare science." —Marian Stamp Dawkins, Department of Zoology, University of Oxford Understanding Animal Welfare: The Science in its Cultural Context takes a completely fresh and thought-provoking approach. It is essential reading for anyone interested, studying or currently working in the fascinating field of animal welfare science. David Fraser places modern-day welfare issues within their historical framework by tracing the evolving ideas that led to current thinking. He also highlights some intriguing issues relating to the contradiction inherent in the term 'animal welfare science' and the practical problem of how to assess emotional states in animals. Special features: Encompasses ideas from a variety of disciplines to give a broad perspective of the topic. Discusses methods of measuring animal welfare and their strengths and limitations. Examines contemporary debates and applications of the science to policy issues. "... an impressive historical narrative of the genesis and growth of animal welfare as a scientific discipline.... The book will be invaluable for anyone involved with animal welfare issues on an academic level or those involved with the integration of these principles into current care and handling issues facing agriculture, companion, laboratory, wild, or zoo animals." —Carolyn L. Stull, PhD, Veterinary Medicine Extension, School of Veterinary Medicine, University of California, Davis "Fraser offers insights only possible from someone with his considerable experience and understanding." —Dr. Chris Sherwin, Department of Clinical Veterinary Science, University of Bristol This book is part of the UFAW/Wiley-Blackwell Animal Welfare Book Series. This major series of books produced in collaboration between UFAW (The Universities Federation for Animal Welfare), and Wiley-Blackwell provides an authoritative source of information on worldwide developments, current thinking and best practice in the field of animal welfare science and technology.
