Farm animals are grown mainly to provide high quality proteins for human use, in the form of meat, milk, eggs, skin and wool. These products are usually formed from lower-quality proteins in complex processes that involve losses through digestion, absorption, and transport. Because proteins are the most expensive major component of the animal diet per unit of weight, the efficiency with which they are used is of great importance biologically and economically. This book begins with a description of the dietary proteins and methods for their measurement. This is followed by detailed accounts of their digestion in ruminants, pigs, poultry and fish. The physiological basis of adsorption of amino acids is discussed in detail. This is followed by reviews of the processes of protein synthesis and degradation and the hormonal and energetic regulation of these processes. Written by a group of experienced scientists, this is the first book in which all of these topics are discussed in detail at a fundamental level. For advanced students and research workers in animal science and agriculture.

Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.
