Air Emissions from Animal Feeding Operations by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Board on Agriculture and Natural Resources,Committee on Animal Nutrition,Ad Hoc Committee on Air Emissions from Animal Feeding Operations Pdf
Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
Livestock Feeds and Feeding by Richard O. Kellems,D. C. Church Pdf
With new "World Markets" opening, the challenge to boost the Production efficiency of livestock products is increasing. The cost of feeding accounts for the largest single input in a production operation, thus, there is a need for a better understanding of nutrition and feeding. Written to appeal to both experts and beginners in the field, this new edition provides the reader with an understanding of the principles relating to livestock feeding. Parts I and II cover everything from nutrients, feedstuffs, minerals, vitamins, and additives to feed preparation/processing and ration formulation. Part III provides detailed information on different livestock species, such as, swine, poultry, dairy cows, beef cows and cattle. Domesticated species, such as horses, sheep, goats, dogs, cats, and rabbits are covered in Part IV Each species chapter discusses the management and feeding practices unique to that particular species. Feedstuff characteristics and nutrient guidelines are given for various classes of the species in the Appendix Tables. Advances in genetics, changes in scientific knowledge, food security, and concerns about the environment are just a few of the areas that have had an impact on livestock production. Because of these changes, it is essential that individuals and companies understand the effect feeding and management of livestock have on livestock production systems. Kellems and Church's "Livestock Feeds and Feeding, 5th edition, " provides the basis for this understanding and is a handy reference for anyone involved in livestock production.

Livestock by Victor R. Squires,Wayne L. Bryden Pdf
This book brings together and discusses information relating to animal production systems in different parts of the world. Throughout this book there are examples of systems comprised of a collection of interdependent and interactive elements that act together to accomplish a desired outcome. As indicated in the Preface, editors sought to give a broad description of existing systems of livestock production in different parts of the world. They discuss some of their important components and try to identify why and how these components have interacted with the systems being described. By editorial concept and by cross-referencing between chapters. this book should serve as a synthesis of several key issues. Along with the extensive bibliography (some in languages other than English) here, and in each other chapters, we present an approach to global livestock production that is up to date and comprehensive. The editors have commissioned writers from Asia, Africa, Australia, the Americas and Europe. The information they present helps our understanding of the complexity of the issues faced in the rapidly changing world in which we all live. What to do about burgeoning populations, rising living standards, shrinking areas of agricultural and pastoral lands, dilemmas about the morality of eating meat, competition for arable lands to grow food crops for humans or to provide fodder and grain for livestock have not yet been resolved. The books purpose is to provide the reader with a synoptic overview of the role of livestock in the economy and culture of peoples from every continent except Antarctica. This book draws together many aspects related to livestock industries around the world, beginning with an overview of the major production systems. Different geographic zones are associated with certain production systems. These are explained and a more in-depth examination (including case studies) of each is presented. Livestock production is the worlds largest user of land, either directly through grazing or indirectly through consumption of fodder and feed grains. Globally, livestock production currently accounts for some 36 percent of the gross value of agricultural production. In the developed countries, this share amounts to half of total production and in developing countries for almost one-third. Worldwide, animal production from livestock (meat, dairy products, eggs, fiber and hides and skins) is the basis of livelihoods of billions of people. The management (care and welfare) of livestock is called animal husbandry. Animal husbandry as a term covers matters relating to livestock production and management, physiology of animals, reproduction, preservation and protection from disease, nutrition and feeding, housing, welfare and behaviour. The predominant production systems in the world range from extensive pastoral systems to intensive landless systems. The classification is justified by its usefulness in identifying livestock development possibilities. Systems at different stages on the development path face widely differing constraints on their further improvement. This book is particularly valuable in this context. The book has 17 chapters in five parts. The authors are drawn from 12 countries, many from the developing world. They are people with in-depth knowledge of the local situation and provide insights into the role, function and interdependence of people and their livestock. The book will be an invaluable addition to the already comprehensive technical literature on the physiology, behaviour, and genetics of both ruminant and non-ruminant livestock (including poultry, rabbits, and even more exotic mini livestock species that are part of the food chain. Readership will include livestock specialists who wish to learn more about the global situation, personnel from the donor community, the UN agencies, NGOs, geographers and the curious lay persons.
Managing High Grade Dairy Cows in the Tropics by John Moran Pdf
Dairy consumption in Asia has more than doubled over the last 25 years, and has led to more than 50% of the world’s total dairy imports now entering Asian markets. Consequently, Asian countries are seeking to improve their self-sufficiency in dairy produce by developing their local milk industries. Asian livestock importers are looking for increasing numbers of high grade dairy stock from established dairy industries in countries such as Australia and New Zealand. Unfortunately, a major problem encountered throughout Asia has been the poor performance of these exotic high grade dairy heifers when exported from their country of origin to a new, more stressful environment. This has been due to a failure to prepare for their introduction. Exotic dairy cows, particularly those from farms with high levels of herd performance, have high management requirements. If subjected to local and traditional small holder dairy farm practices, they are unlikely to produce acceptable yields of milk or may not even get back into calf. Poor management practices can lead to low growth rates, delayed breeding, stock diseases and even deaths among imported stock both before and after first calving. Managing High Grade Dairy Cows in the Tropics addresses the entire range of management practices found on tropical small holder dairy farms, highlighting those which are likely to adversely impact on heifer and cow performance, hence farm profitability. It is a companion volume to three other manuals written by John Moran: Rearing Young Stock on Tropical Dairy Farms in Asia, Tropical Dairy Farming and Business Management for Tropical Dairy Farmers.

Supplementary Feeding of Sheep and Beef Cattle by David G Hinton Pdf
This practical guide is a tool designed for graziers to use in their day-to-day decision-making about livestock nutritional needs, feeding options, condition and health. Pasture supplements are expensive and should not be wasted, yet under-nutrition has an even greater economic effect resulting from low conception and progeny survival rates, poor growth rates, failure to meet market targets and tender fleeces in sheep. Supplementary Feeding of Sheep and Beef Cattle shows how to get the nutritional balance right and avoid costly repercussions from incorrect or inadequate feeding. The key topics covered will be particularly useful in drought situations, but also in seasonal pasture shortages, when the nutrient value of pastures is low. Practical tables and worksheets are provided as key tools, enabling livestock producers to make timely and cost-effective decisions about supplementary feeding.
Farm Animal Management: Principles And Practices by Rana Ranjit Singh Pdf
Livestock rearing is an integral part of socio-economic framework of India since time immemorial. Livestock sub-sector being a vital component of agriculture sector, plays a multidimensional role and acts as a tool in achieving nutritional security, employment generation and socio-economic development of rural sector, particularly among the landless, small, marginal farmers and women. India possesses huge livestock population of varying production potentials, distributed across different agro-ecological zones under different operational and livestock holding size. Hence, it requires different package of practices for their management. Further, factors like drivers of development change and climate change pose many challenges to this sector. Farm animal management encompasses integrated and precise application of basic scientific principles of breeding, feeding, heeding and weeding in general as well as in times of specific need. Therefore, an attempt has been made in this book to cover all these basic and applied aspects of livestock management in detail. In the perspective of reorganization of the syllabus of veterinary science and animal husbandry programme. This book is appropriately divided into fifteen s covering almost each and every aspect of livestock production management.
The aim of this manual is to improve the welfare of dairy cattle in tropical developing countries, and by doing so, optimise cow and herd performance. It gives the stockmen and farmers directly concerned with the cattle a better understanding of animal behaviour and the ways cattle communicate their comfort or distress. The book discusses normal cattle behaviour and shows how domestication and breeding can affect behaviour to achieve high levels of production of milk, live weight gain and fertility. Animal welfare is important for producers because it can affect the health, production and contentment of cows. Animal welfare practices which adversely affect cow and herd performance on tropical small holder dairy farms are identified. Advice is then given to change the animal's environment or modify a handler's technique to ensure cattle have the degree of comfort needed to achieve more profitable and sustainable systems of livestock farming. Cow Talk will be a beneficial resource for farmers who want to improve animal welfare, farm advisers who can assist farmers to improve their welfare practices, educators who develop training programs for farmers and dairy advisers, and other stakeholders in tropical dairy production such as local agribusiness, policy makers and research scientists.
