Book Description
One of the purposes of practical housing and equipment is to provide for the biological, economic and welfare needs of the birds. Fortunately, the scientific literature contains a great deal of information on these needs, so that a recommended approach to practical problems is to start with an appraisal of the requirements and responses of the birds. Then, designers and engineers can provide for these needs. This book provides information on the needs and responses of poultry to aspects of the climatic environment, by means of reviews of the scientific literature. Biological responses to environmental factors are discussed, as well as some principles of the movement of air through and within buildings. Many of the principles apply to both indoor production and to the housing attached to free range systems.

Book Description
Doctoral Thesis / Dissertation from the year 2011 in the subject Veterinary medicine, grade: none, , course: Health Science, language: English, abstract: Poultry provide globally important sources of animal protein and are amongst the most intensively reared of all livestock species. Diseases of poultry are therefore of major concern, both locally and on an international scale. Poultry production have been brought to the edge, because of the large numbers of infectious diseases outbreaks; that strikes the poultry farms from time to time in the absence of good hygiene. It is also important to consider the concept of, and the need for, biosecurity or the range of management procedures designed to protect livestock from infection. The low productivity in traditional systems is mainly due to high mortality, which is caused by mismanagement, diseases, lack of nutritional feeding and predators. In traditional systems the mortality has been estimated to be in the range of 80 - 90% within the first year after hatching, (Permin and Bisgaard, 1999). Diagnosis, treatment and/or prevention of diseases are of major importance to any attempts at increasing productivity. Backyard poultry production systems (BPS) are an important and widespread form of poultry production. There is a common perception that biosecurity standards in BPS are generally poor and BPS are usually associated with poultry diseases and zoonoses, (Hamilton-West, et al, 2011) The structure of the poultry meat and egg production industries provides both challenges and opportunities in the area of poultry health; one of these challenges is the existence of very high-density populations of commercial poultry. Such circumstances provide an ideal medium for multiplication and spread of all kinds of micro-organisms including pathogens, such as Salmonella spp that can strike all ages specially chicks and still considered one of the most important world wild food poisoning diseases, (Vugia, et al, 2006). The importance of Salmonella bacterium has increased dramatically in recent years since it assumed a political role to complement its pathogenic one. Only a few serotypes out of some 3000 caused disease in poultry but most of Salmonella serotypes, given the right set of circumstances, can cause food poisoning such as Salmonella enterica serovar Enteritidis & Typhimurium which are the world leading cause of Salmonellosis and is often implicated in over 60.0% of human Salmonellosis, (Patrick, et al, 2004).

Book Description
This open access book discusses current thinking and presents the main issues and challenges associated with climate change in Africa. It introduces evidences from studies and projects which show how climate change adaptation is being - and may continue to be successfully implemented in African countries. Thanks to its scope and wide range of themes surrounding climate change, the ambition is that this book will be a lead publication on the topic, which may be regularly updated and hence capture further works. Climate change is a major global challenge. However, some geographical regions are more severly affected than others. One of these regions is the African continent. Due to a combination of unfavourable socio-economic and meteorological conditions, African countries are particularly vulnerable to climate change and its impacts. The recently released IPCC special report "Global Warming of 1.5o C" outlines the fact that keeping global warming by the level of 1.5o C is possible, but also suggested that an increase by 2o C could lead to crises with crops (agriculture fed by rain could drop by 50% in some African countries by 2020) and livestock production, could damage water supplies and pose an additonal threat to coastal areas. The 5th Assessment Report produced by IPCC predicts that wheat may disappear from Africa by 2080, and that maize— a staple—will fall significantly in southern Africa. Also, arid and semi-arid lands are likely to increase by up to 8%, with severe ramifications for livelihoods, poverty eradication and meeting the SDGs. Pursuing appropriate adaptation strategies is thus vital, in order to address the current and future challenges posed by a changing climate. It is against this background that the "African Handbook of Climate Change Adaptation" is being published. It contains papers prepared by scholars, representatives from social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects in Africa, and working with communities across the African continent. Encompassing over 100 contribtions from across Africa, it is the most comprehensive publication on climate change adaptation in Africa ever produced.

Book Description
Advances in Poultry Welfare provides a targeted overview of contemporary developments in poultry welfare. The reviews in the volume address topical issues related to poultry welfare research and assessment, with a focus on identifying practical strategies for improvement as well as information gaps that remain to be filled. Part One provides an introduction to poultry production systems and gives a broad overview of current poultry welfare issues. Part Two moves on to review several aspects of poultry management, focusing on hatchery practices, early rearing, and slaughter. Part Three deals with welfare assessment on the farm, while Part Four explores continuing challenges, such as feather pecking and skeletal problems. This is followed in Part Five by a discussion of emerging issues, with chapters covering alternative parasite control methods, backyard poultry production, mass depopulation, and genetic approaches to reducing the impact of environmental stressors on welfare. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs, and poultry. With its expert editor and international team of contributors, Advances in Poultry Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of poultry. Provides in-depth reviews of emerging topics, research and applications in poultry welfare Integral part of a wider series, Advances in Agricultural Animal Welfare, which will provide comprehensive coverage of animal welfare of the world’s major farmed animals Covers a range of topical issues within the field, from beak-trimming and skeletal problems, to early rearing and the design and management of poultry production systems Edited by a distinguished leader in the field
