Book Description
This study examined fenceline contact between beef calves and cows at weaning and the subsequent comparisons for behavioral distress and related reductions in weight gain. Eighty-seven crossbred calves were randomly assigned to 3 treatment groups for eight weeks. Six replications were conducted to determine the effect of different weaning techniques on their subsequent growth while three replications were observed for behavioral differences. Treatments were 1) fenceline separation from dams for one week, 2) fenceline separation from dams for two weeks, and 3) total separation (abrupt weaning) from their dams. Calves were weighed on the day of weaning and at 7, 14, 35 and 56 days post-weaning. In the days following weaning, the one-week fenceline weaned calves spent more time eating (eating hay) than either the total separation or two week fenceline weaned treatments (P

Book Description
The coyote is the major predator of livestock in Alberta. This booklet explains the ecology of coyote predation of livestock and how to recognize attacks on livestock by coyotes and other common predators. It then describes the various techniques to prevent and control livestock predation by coyotes. These include non-lethal methods such as flock and herd management and the use of electric fences, guardian dogs, and frightening devices; and lethal methods such as shooting, poisoning, and trapping.

Book Description
Cheetahs: Biology and Conservation reports on the science and conservation of the cheetah. This volume demonstrates the interdisciplinary nature of research and conservation efforts to study and protect the cheetah. The book begins with chapters on the evolution, genetics, physiology, ecology and behavior of the species, as well as distribution reports from range countries. These introductory chapters lead into discussions of the challenges facing cheetah survival, including habitat loss, declining prey base, human-wildlife conflict, illegal trade, and newly-emerging threats, notably climate change. This book also focuses on conservation strategies and solutions, including environmental education and alternative livelihoods. Chapters on the role of captive cheetahs to conservation and the long-term research of the species are included, as are a brief discussion of the methods and analyses used to study the cheetah. The book concludes with the conservation status and future outlook of the species. Cheetahs: Biology and Conservation is a valuable resource for the regional and global communities of cheetah conservationists, researchers, and academics. Although cheetah focussed the book provides information relevant to the study of broader topics such as wildlife conservation, captive breeding, habitat management, conservation biology and animal behaviour. Cover photograph by Angela Scott - Includes chapters by the world's leading cheetah researchers and practitioners, who have focused their efforts on this high-profile species of conservation concern - Provides findings as a combination of scientific detail and basic explanations so that they can be available not only to cheetah researchers and conservationists, but also to policy makers, business leaders, zoo managers, academics, students, and people interested in the cheetah and its future - Presents the current knowledge of the species, helping lay the foundations and best practices for cheetah conservation and research worldwide - Additional protocols and forms (which were provided by authors) can be found at the Cheetahs: Biology and Conservation companion site: https://www.elsevier.com/books-and-journals/book-companion/9780128040881

Book Description
With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

Book Description
Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Book Description
During the Vietnam war, the United States sought to undermine Hanoi's subversion of the Saigon regime by sending Vietnamese operatives behind enemy lines. A secret to most Americans, this covert operation was far from secret in Hanoi: all of the commandos were killed or captured, and many were turned by the Communists to report false information. Spies and Commandos traces the rise and demise of this secret operation-started by the CIA in 1960 and expanded by the Pentagon beginning in1964-in the first book to examine the program from both sides of the war. Kenneth Conboy and Dale Andrade interviewed CIA and military personnel and traveled in Vietnam to locate former commandos who had been captured by Hanoi, enabling them to tell the complete story of these covert activities from high-level decision making to the actual experiences of the agents. The book vividly describes scores of dangerous missions-including raids against North Vietnamese coastal installations and the air-dropping of dozens of agents into enemy territory-as well as psychological warfare designed to make Hanoi believe the "resistance movement" was larger than it actually was. It offers a more complete operational account of the program than has ever been made available-particularly its early years-and ties known events in the war to covert operations, such as details of the "34-A Operations" that led to the Tonkin Gulf incidents in 1964. It also explains in no uncertain terms why the whole plan was doomed to failure from the start. One of the remarkable features of the operation, claim the authors, is that its failures were so glaring. They argue that the CIA, and later the Pentagon, was unaware for years that Hanoi had compromised the commandos, even though some agents missed radio deadlines or filed suspicious reports. Operational errors were not attributable to conspiracy or counterintelligence, they contend, but simply to poor planning and lack of imagination. Although it flourished for ten years under cover of the wider war, covert activity in Vietnam is now recognized as a disaster. Conboy and Andrade's account of that episode is a sobering tale that lends a new perspective on the war as it reclaims the lost lives of these unsung spies and commandos.
