Amino acid content as an estimate of quality for humans; Reducing variability in amino acid analysis; Interactions between proteins and constituents that affect protein quality; In vitro methods to measure sulfur amino acid availability; Amino acids in cereal proteins and protein fractions; Proteins in developing and germinating cereal grains and grain fractions; Functional and nutritional characteristics of cereal proteins; Effects of food processing on protein digestibylity and amino acid availability; In vitro methods to predict lysine availability; Direct measurements of amino acid digestibility in swine; Digestibility of plant proteins: animal studies; Absorption of products of protein digestion.
Containing 45 papers written by outstanding international authors from 14 countries, this three-volume compendium brings together the elements needed to understand the factors which influence the utilization of amino acids. The wide-ranging topics include descriptions of metabolic pathways and mechanisms of the biological utilization of amino acids, as well as factors that influence amino acid bioavailability in enteral and parenteral nutrition. The use of amino acids to improve the quality and safety of the diet is presented. Also discussed are amino acid precursors of biogenic amines and the role of amino acids in atherosclerosis, cancer, and immunity. Scientists from many disciplines will benefit from this broad overview.
Cereals belong to the most important elements in the history of mankind. From the beginning of agriculture, cereals have been by far the most important staple food in the world. Although the cereal consumption decreased to a low level in the developed countries in Europe and North America, in the devel oping countries over two-thirds of the calorie and protein intake is based on cereals. A substantial quantity of cereals goes indirectly into food via feed to animals. Generally, cereal proteins are classified as proteins of lower biological value because of shortage in lysine and some other essential amino acids. Recent developments in the de termination and evaluation of the biological value of proteins and protein mixtures suggest that the oversimplified earlier evaluation of cereal proteins must be reviewed. This book contains the edited proceedings of the Inter national Symposium on "Amino Acid Composition and Biological Value of Cereal Proteins", held in Budapest, Hungary, Hay 31- June 1, 1983, under the sponsorship of the International Association for Cereal Chemistry, Hungarian Scientific Society for Food Industry and Grain Trust, Hungary, with supplemental invited contributions. Scientists (biologist, plant breeders, farmers, chemists, biochemists, engineers, food technologists and nutritionists) from 17 countries presented and reviewed, along with partici pants from 20 countries, the recent methodology and trends in the determination of the biological value of cereal proteins, v the amino acid composition of cereal proteins and factors in fluencing the composition and the role of cereal proteins in nutrition and animal feeding.
In the past decade, since the first edition was published, the study of cereal protein chemistry has grown and changed. New separation techniques have been introduced while the application of achievements of molecular biology and genetic engineering of proteins has progressed dramatically. This new edition includes these advances and updates the chemistry of cereal proteins for all specialists working in theory and practice of cereal grain production and processing.
This thoroughly revised second edition addresses the full spectrum of cereal grain science, employing agronomic, chemical, and technological perspectives and providing new and expanded treatment of food enrichment techniques, nutritional standards, and product quality evaluation. Written by over 40 internationally respected authorities, the
This book addresses various aspects of in vitro digestibility: • Application of meta-analyses and machine learning methods to predict methane production; • Methane production of sainfoin and alfalfa; • In vitro evaluation of different dietary methane mitigation strategies; • Rumen methanogenesis, rumen fermentation, and microbial community response; • The role of condensed tannins in the in vitro rumen fermentation kinetics; • Fermentation pattern of several carbohydrate sources; • Additive, synergistic, or antagonistic effects of plant extracts; • In vitro rumen degradation and fermentation characteristics of silage and hay; • In vitro digestibility, in situ degradability, and rumen fermentation of camelina co-products; • Ruminal fermentation parameters and microbial matters to odd- and branched-chain fatty acids; • Comparison of fecal versus rumen inocula for the estimation of NDF digestibility; • Rumen inoculum collected from cows at slaughter or from a continuous fermenter; • Seaweeds as ingredients of ruminant diets; • Rumen in vitro fermentation and in situ degradation kinetics of forage Brassica crops; • In vitro digestibility and rumen degradability of vetch varieties; • Intestinal digestibility in vitro of Vicia sativa varieties; • Ruminal in vitro protein degradation and apparent digestibility of Pisum sativum; • In vitro digestibility studies using equine fecal inoculum; • Effects of gas production recording system and pig fecal inoculum volume on kinetics; • In vitro methods of assessing protein quality for poultry; and • In vitro techniques using the DaisyII incubator.
Recent Advances in Animal Nutrition: 1991 is an annual review of the changes and updates in the field of animal nutrition, especially progresses in the study of feeds. The book is divided into five parts. Part I discusses topics related to pig nutrition and feeds such as energy-protein interactions and improved utilization of amino acids. Part II covers the nutrition and growth of poultry. Part III talks about the legislations concerned with feed manufacture, and Part IV deals with nutrition of different animals such as chicks and ruminants. The text is recommended for agriculturists, zoologists, and those involved in the development and manufacture of feeds who would like to know more about the nutrition of agriculturally important animals.
