Book Description
Cattle producers may feed phosphorus above the levels required for nutrition and the extra nutrients can therefore end up in the manure, resulting in higher than necessary feed bills and possibly leading to undesirable environmental consequences. This bulletin explains the environmental & economic effects of excess phosphorus in dairy cattle feed, and provides information on the phosphorus requirements of cattle and how to adjust feed rations to minimize costs & phosphorus output to manure while ensuring adequate nutrition.

Book Description
Nutrient management is an important aspect of feeding livestock and poultry. Today, there is more attention directed toward this issue in animal production than ever before. The heightened awareness of the environmental impacts associated with animal production has caused animal nutritionists to refocus their thoughts, practices, and expectations regarding how nutrients are supplied to animals. In addition, the increase in the size and intensity of modern production units demands new technologies for enhancing nutrient utilization and for reducing the amount of nutrients excreted. Covering these issues and more, Nutrient Management of Food Animals to Enhance and Protect the Environment is a reference tool for agricultural industry leaders, private practitioners, governmental agencies, and researchers.

Book Description
The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.

Book Description
This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.

Book Description
In order to meet increasing global demand for meat and animal by-products increasingly intensive animal production is necessary. Creating a sustainable system in animal agriculture that works in different production environments is a major challenge for animal scientists. This book draws together themes on sustainability that have emerged as the most pressing in recent years. Addressing practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues, animal welfare concerns, societal impacts and an analysis of the data used to assess the economic sustainability of farms.

Book Description
Mineral nutrition of livestock is an area of significant importance due to its contribution to farm animal economics and health. Providing animals with the required levels of nutrients can improve development, growth and productivity, but production systems increasingly need to be considered alongside issues of economy and environmental sustainability. With a focus on macromineral utilization in farm animals, this book brings together quantitative aspects of phosphorus and calcium metabolism in farm animals, in chapters written by leading researchers worldwide. Chapters cover the isotope dilution technique, phosphorus and calcium utilization in ruminants (sheep, goats and cattle) and non-ruminants (swine and horses) and recommended values of phosphorus and calcium inclusion in feed. Providing information on the efficiency of utilization, availability and requirements in livestock and interactions between the animal and the environment, this is an essential resource for researchers and students in animal sciences and nutrition.
