The intake of food by fishes is an area of study that is of great importance to the applied sciences of fisheries and aquaculture for a number of reasons. For example a thorough knowledge of factors influencing the ingestion of feed can lead to successful manipulation of the rearing environment of cultured fishes, thereby ensuring improved growth performance and feed utilisation, and decreasing the amount of waste (and consequent pollution) per unit of fish produced. This important book, which has arisen out of a European Union COST programme, illustrates how insights into the biological and environmental factors that underlie the feeding responses of fish may be used to address practical issues of feed management. Food Intake in Fish contains carefully edited contributions from internationally recognised scientists, providing a book that is an invaluable tool and reference to all those involved in aquaculture, especially those working in the aquaculture feed industry and scientific personnel in commercial and research aquaculture facilities. This book should also find a place on the shelves of fish biologists and physiologists and as a reference in libraries of universities, research establishments and aquaculture equipment companies.

How much do animals eat? Why do eating patterns change? How do physiological, dietary, and environmental factors affect feed intake? This volume, a comprehensive overview of the latest animal feed intake research, answers these questions with detailed information about the feeding patterns of fishes, pigs, poultry, dairy cows, beef cattle, and sheep. Equations for calculating predicted feed intake are presented for each animal and are accompanied by charts, graphs, and tables.

Presents the State-of-the-Art in Fat Taste TransductionA bite of cheese, a few potato chips, a delectable piece of bacon - a small taste of high-fat foods often draws you back for more. But why are fatty foods so appealing? Why do we crave them? Fat Detection: Taste, Texture, and Post Ingestive Effects covers the many factors responsible for the se

Provides a historical foundation as well as a review of the state-of- the-art in forage science, detailing 25 years of progress in forage quality, evaluation, and utilization, along with the latest developments and new directions for future research. The volume is divided into six sections: overview of forage science; identification and quantitative measurement of forage quality components; intake as a critical element of forest quality; role of digestion and metabolism in determining forage quality; integrating concepts affecting changes in forage quality; and improving forage quality and evaluation.

This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.

Disturbances in the gastrointestinal (GI) tract caused by internal and external influences can cause large economic losses in both the pig and poultry industries. Traditionally, diseases and conditions of the GI tract that can cause losses have been controlled by antimicrobial compounds administered in the feed and (or) water, such as antibiotics, coccidiostats, zootechnical feed additives and trace elements such as zinc and copper. However, legislation and rulings in various parts of the world coupled with a growing sentiment to reduce the use of these compounds in the intensive livestock industries have caused a reassessment of measures to influence GI tract structure and function ('gut health'), and have caused unparalleled interest in alternative strategies (genetic, dietary, management, environmental) to effectively manage the GI tract under conditions of external and internal challenge. Despite the wide array of products and strategies available to the pig and poultry industries that influence 'gut health', a term in itself that is often misunderstood and misinterpreted, it is important that the industries continue to investigate and understand the underpinning sciences that influence GI tract structure and function, especially at critical life stages. Ultimately, the cost-benefit of adopting such practices to influence 'gut health' requires consideration.

This book presents specially commissioned reviews of key topics in farm animal metabolism and nutrition, such as repartitioning agents, near infrared reflectance spectroscopy and digestibility and metabolisable energy assays, where major advances have recently been made or which continue to represent issues of significance for students and researchers. Authors include leading researchers from Europe, North America and Australia.

When an excessive proportion of the human energy requirement is derived from fat, the likelihood of obesity increases. Any such individual is at risk for diabetes and cardiovascular disease- grave and costly health hazards. The selective control of fat ingestion is a promising solution to these concerns. Existing data suggests that macronutrient intake can be manipulated. Further research is working to create pharmacological tools that will suppress fat consumption. It will also be possible to fight obesity, heart disease and diabetes. Neural and Metabolic Control of Macronutrient Intake systematically discusses the known physiological mechanisms involved in macronutrientselection, including their molecular, genetic and neurochemical aspects. The book is also a critical review of the hypothesis that ingestion of the three nutrients is regulated by separate neural control mechanisms, leaving open the possibility that strategies could be devised to intervene in bodily control systems and alter the proportion of fat in the diet. This reference provides three types of information: First, the basic background of the biochemical and physiological systems as they relate to macronutrient selection. Second, opinions and data concerning to what degree animals and humans show evidence of macronutrient selection. And, third, evidence about how the central nervous system might be involved in the choices animals make among macronutrients.

In the years since the third edition of this indispensable reference was published, a great deal has been learned about the nutritional requirements of common laboratory species: rat, mouse, guinea pig, hamster, gerbil, and vole. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. The extensive use of tables provides easy access to a wealth of comprehensive data and resource information. The volume also provides an expanded background discussion of general dietary considerations. In addition to a more user-friendly organization, new features in this edition include: A significantly expanded section on dietary requirements for rats, reporting substantial new findings. A new section on nutrients that are not required but that may produce beneficial results. New information on growth and reproductive performance among the most commonly used strains of rats and mice and on several hamster species. An expanded discussion of diet formulation and preparationâ€"including sample diets of both purified and natural ingredients. New information on mineral deficiency and toxicity, including warning signs. This authoritative resource will be important to researchers, laboratory technicians, and manufacturers of laboratory animal feed.
