Book Description
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.

Book Description
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.

Book Description
Management Strategies for Sustainable Cattle Production in Southern Pastures is a practical resource for scientists, students, and stakeholders who want to understand the relationships between soil-plant interactions and pasture management strategies, and the resultant performance of cow-calf and stocker cattle. This book illustrates the importance of matching cattle breed types and plant hardiness zones to optimize cattle production from forages and pastures. It explains the biologic and economic implications of grazing management decisions made to improve sustainability of pastures and cattle production while being compliant with present and future environmental concerns and cattle welfare programs. - Documents the effects of cattle grazing on greenhouse gas emissions and carbon footprints - Discusses strategies to enhance soil fertility, soil health, and nutrient cycling in pastures - Provides information on the use of stocking rates, stocking strategies and grazing systems to optimize cow-calf production of weaned calves and stockers. - Presents innovations in cattle supplementation and watering systems to minimize negative impacts on water and soil health - Includes methods for weed control to maintain pasture condition and ecosystem stability - Describes management strategies to integrate cattle operations with wildlife sustainability

Book Description
Tropical Dairy Farming is a manual designed for use by dairy production advisors working in tropical areas, especially in South-East Asia. It aims to increase the productivity of small holder dairy farmers in the humid tropics by improving the feeding management of their livestock. It shows how to provide dairy cows with cost-effective feeds that match small holder farming systems and discusses the major obstacles to improving feeding management in the humid tropics. The author shows the benefits and drawbacks of various feed components and the calculation of balanced diets based mainly on forages combined with some supplementary feeding. Diseases and problems associated with unbalanced diets are also covered, as well as important information on growing and conserving quality forages as silage. The book draws on examples from a variety of countries including Indonesia, Malaysia, Thailand, Vietnam, China, East Timor and the Philippines.

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
Dairy goats have long been considered an important source of income for rural populations, providing the opportunity for profitable and sustainable diversity for small farms. Their importance is also increasing in intensive feeding systems and in large farms. They are highly adaptable due to their unique feeding habits and have become popular livestock animals in a range of environments, from temperate grasslands to subtropical, semi-arid and mountainous areas. Moreover, goat milk products are finding a growing acceptance in the world market and research has increased in feeding strategies for improved productivity and quality. Examining all aspects of dairy goat feeding and nutrition, this book represents a long awaited review of recent scientific research and updated techniques. Chapters discuss aspects such as the modelling and production of goat's milk as well as the estimation of nutrient requirements and food intake of goats.
