The Voluntary Food Intake of Farm Animals offers a wide discussion on food intake among farm animals. The book presents various studies, facts, details, and theories that are relevant to the subject. The first chapter begins by explaining the basic definition and significance of voluntary food intake. This topic is followed by discussions on meal patterns, the main features of eating, and the similarities between species. The next chapter explores theories about the food intake control, which are divided into two types: single-factor theories and multiple-factor theories. In Chapter 3, the discussion is on the food's pathway, including elaborations on the various receptors. Chapter 4 considers the central nervous system's involvement in the voluntary food intake and the energy balance regulation. The next couple of chapters highlight the possible reasons that affect food intake; among them are pregnancy, fattening, physical growths, and the environment. In the book's remaining chapters, the discussion revolves around grass intake and the prediction and manipulation of voluntary food intake. The book serves as a valuable reference for undergraduates and postgraduates of biology and its related fields.

The tenth edition of this essential reference presents new knowledge about the nutritional needs of swine that consider such factors as growth rate, carcass leanness, gender, health, environment, and repartitioning agents. New sections are presented on requirements for amino acids and other nutrients. In addition, an original modeling approach to arriving at energy and amino acid needs for given animals is incorporated in this revision. The book comes with a CD-ROM that allows users to create tables of nutrient requirements for swine of a specific body weight and level of productivity. Nutrient Requirements of Swine covers: Biological concepts that underlie nutrient needs for growth and function. New data on amino acid and energy requirements and the factors that shape them. New findings on lysine and the bioavailability of amino acids. New research results on minerals and vitamins. Nutrient composition of an expanded list of feedstuffs. The role of water in swine physiology, including factors that affect the quality of drinking water. Expanded tables of feed ingredients and their nutrient composition provide bioavailability estimates, fatty acid composition of fats typically used in swine diets, and important information on estimating the amino acid content of crude protein.

As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

This authoritative reference volume emphasizes the importance and interrelationships of geological processes to the health and diseases of humans and animals. Its accessible format fosters better communication between the health and geoscience communities by elucidating the geologic origins and flow of toxic elements in the environment that lead to human exposure through the consumption of food and water. For example, problems of excess intake from drinking water have been encountered for several inorganic compounds, including fluoride in Africa and India; arsenic in certain areas of Argentina, Chile, and Taiwan; selenium in seleniferous areas in the U.S., Venezuela, and China; and nitrate in agricultural areas with heavy use of fertilizers. Environmental influences on vector borne diseases and stormflow water quality influences are also featured. Numerous examples of the environmental influences on human health from across the globe are also presented and discussed in this volume.* Covers recent advances and future research topics at the intersection of environmental science and public health* Developed by 60 experts from 20 countries and edited by professionals from the International Working Group on Medical Geology* Includes 200+ color photographs and illustrations* Organizes information in a highly structured format for easy reference* Written for a broad audience, ranging from students, researchers, and medical professionals to policymakers and the general public
