Feed Energy Sources for Livestock focuses on the compositions of animal feeds. The book first looks at the background of world grain supplies from 1972 to 1974 and 1975 onwards. The text discusses alternatives to conventional cereals. Fats in ruminants, pigs, and poultry diets; chemically treated straw; and less conventional raw materials are described. The book also looks at molasses and its by-products, processing of cereals, and the effects of an alkali technique on the nutritive value of straws. The text discusses as well the laboratory methods used in evaluating the energy value of feedstuffs. Neutral detergent fiber; in vitro rumen digestibility; Tilley and Terry in vitro rumen method; in vitro true digestibility; and modified acid detergent fiber are considered. The book then focuses on the sources, availability, and use of additional phosphorous for ruminants; selenium and Vitamin E in poultry rations; and the use of rapeseed meal in pig and poultry rations. The selection is a valuable source of information for readers wanting to study the contents of animal feeds.

Light and Plant Development presents the Proceedings of the 22nd University of Nottingham Easter School in Agricultural Science. It discusses the spectral sensitivity of inhibition of flowering by light. It addresses the action spectrum for leaf enlargement and stem growth inhibition. Some of the topics covered in the book are the nature of the blue light photoreceptor in higher plants and fungi; re-examination of photochemical properties and absorption characteristics of phytochrome using high-molecular-weigh... preparations; and intermediates in the photoconversion of phytochrome. The high irradiance reaction is fully covered. The physiological evidence and localised responses, intracellular localisation and action of phytochrome are discussed in detail. The text describes in depth the immunological visualisation of phytochrome. The fractionation procedures and terminology are presented completely. A chapter is devoted to the photocontrol of enzyme levels. Another section focuses on the ribosomal RNA synthesis in developing leaves. The book can provide useful information to botanists, chemists, students, and researchers.

Adaptation to Environment: Essays on the Physiology of Marine Animals contains a series of essays that is intended as a review of the special adaptations of marine organisms to the particular environmental conditions they are likely to encounter in the natural habitat. This book emphasizes developments in physiology of marine animals and on approaches to the study of the adaptations of marine organisms. This compilation also interprets the term “Physiology” in its widest sense to include all aspects of the functioning of the organism from the behavior of animals to the mode of function of enzymes. For this reason, structural adaptations have been reviewed in detail only where their functional role is understood and where they constitute a specific adaptation to defined environmental conditions. This publication benefits students and individuals conducting research on the physiology of marine animals.

Plant Proteins is a compendium of papers discussing, in general, plant proteins as materials for human foods, and in particular, the properties, biosynthesis, deposition of reserves in seeds, undesirable factors, production, and nutritional aspects of plant proteins in the food industry. Some papers review the properties and biosynthesis of plant proteins, the synthesis of chloroplast proteins, and legume seed proteins. Other papers discuss the development of protein reserves in seeds, as well as the toxicity and antagonistic actions in relation to amino acid and protein synthesis. One paper examines the world supply and demand for sources of protein from three plant sources, namely cereals, oilseeds, and legumes. Another paper discusses the capabilities of certain species of micro-organisms to synthesize from a few simple raw materials all the main components needed in the diet of a human or a farm animal. One paper notes that the acceptance of plant protein foods in society depends on their presentation, flavor, texture, appearance, identity, and product name. This compendium will benefit agronomists, agriculturists, biochemists, microbiologists, nutritionists, botanists, chemists, economists, food scientists, physicists and plant breeders.

Recent Advances in Animal Nutrition-1977 presents papers that tackle the various areas of concerns in raising ruminants. The book contains a total of 11 studies that examine the factors affecting rumen fermentation. The text first covers EEC and feed compounding, and then proceeds to discussing the aspects of the biochemistry of rumen fermentation. Chapter 3 examines the influence of nitrogen and carbohydrate inputs on rumen fermentation. Chapter 4 talks about reducing the rate of ammonia release through alternative non-protein nitrogen sources. The fifth chapter describes the potential of protected proteins in ruminant nutrition. Next, the book discusses the manipulation of rumen fermentation. Chapter 7 covers the application of non-protein nitrogen, protected proteins, and rumen fermentation control. The next two chapters deal with broilers and turkeys. The eleventh chapter talks about predicting growth response in pigs, while the last chapter covers fish nutrition. The book will be most useful to both researchers and practitioners of animal related disciplines, such as agriculture and veterinary medicine.

Recent Advances in Animal Nutrition-1978 is a collection of papers that tackles various topics concerning livestock feeding. The book presents a total of 12 materials that cover different livestock, particularly poultry, pigs, and dairy cows. The text first covers poultry feeding related topics, such as the factors affecting amino acid requirements of meat birds; protein-energy interactions in broiler and turkey rations; and nutrition-disease interactions of leg weakness in poultry. Next, the book tackles pig feeding concerns, including amino acid nutrition of the pig; energy requirements of the growing pig; and processing and preparation of cereals for pig diets. The remaining chapters discuss topics relevant to dairy cow diet, such as ratios for high-yielding dairy cows; concentrate feeding of dairy cows; and complete-diet feeding of dairy cows. The text will be most useful to both researchers and practitioners of animal related disciplines, such as agriculture and veterinary medicine.
