Current pressures to maximise the use of forages in ruminant diets have renewed interest in fast, inexpensive methods for the estimation of their nutritional value. As a result, a wide variety of biological and physiochemical procedures have recently been investigated for this purpose.This book is the single definitive reference volume on the current status of research in this areaCovers all forages eaten by ruminant animals
Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. Part II discusses the cow's nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.
Recent Advances in Animal Nutrition—1984 documents the proceedings of the Eighteenth Annual Nutrition Conference for Feed Manufacturers. It covers a wide range of topics pertaining to the nutrition of farm livestock. The volume is organized into four parts. Part I on poultry nutrition contains papers relating to carcass quality in broilers. These deal with the influence of diet and genotype, and various aspects of meat quality. Part II on pig nutrition includes studies on the nutrition of early weaned pigs; differences in the recommendations of the Agricultural Research Council (UK) and the National Research Council (US) for energy and protein for growing pigs; and the importance of ileal digestibility of proteins in pig feeds. Part III on ruminant and horse nutrition includes papers on the efficacy of a wide range of substances for the manipulation of rumen fermentation to increase the efficiency of production; and new chemical methods for predicting the nutritive value of forages. Part IV on dairy cow nutrition addresses the practical aspects of feeding protein to dairy cattle and manipulation of milk composition by dietary means.
This book explores in depth the relationships between nutrition and oral health. Oral health is an integral part of general health across the life course, and this book examines nutritional and oral health considerations from childhood through to old age, with particular attention focused on the consequences of demographic changes. Current knowledge on the consequences of poor diet for the development and integrity of the oral cavity, tooth loss, and the progression of oral diseases is thoroughly reviewed. Likewise, the importance of maintenance of a disease-free and functional dentition for nutritional well-being at all stages of life is explained. Evidence regarding the impact of oral rehabilitation on nutritional status is evaluated, and strategies for changing dietary behaviour in order to promote oral health are described. Nutrition and Oral Health will be an ideal source of information for all who are seeking a clearly written update on the subject.
Nutrition and Epigenetics presents new information on the action of diet and nutritional determinants in regulating the epigenetic control of gene expression in health and disease. Each chapter gives a unique perspective on a different nutritional or dietary component or group of components, and reveals novel mechanisms by which dietary factors mod
Animal products are good source of disposable income for many small farmers in developing countries. In fact, livestock are often the most important cash crop in many small holder mixed farming systems. Livestock ownership currently supports and sustains the livelihoods of rural poor, who depend partially or fully on livestock for their income and/or subsistence. Human population growth, increasing urbanization and rising incomes are predicted to double the demand for, and production of, livestock products in the developing countries over the next twenty years. The future holds great opportunities for animal production in developing countries. Animal Sourced Foods for Developing Economies addresses five major issues: 1) Food safety and nutritional status in developing world; 2) the contribution of animal origin foods in human health; 3) Production processes of animal foods along with their preservation strategies; 4) functional outcomes of animal derived foods; and finally, 5) strategies, issues and polices to promote animal origin food consumption. Animal sourced food contain high biological value protein and important micronutrients required for optimal body functioning but are regarded as sources of fat that contribute to the intake of total and saturated fatty acids in diet. The quality of protein source has a direct influence on protein digestibility, as a greater proportion of higher quality proteins is absorbed and becomes available for bodily functions. Animal foods has high quantity and quality of protein that includes a full complement of the essential amino acids in the right proportion. Land availability limits the expansion of livestock numbers in extensive production systems in most regions, and the bulk of the increase in livestock production will come from increased productivity through intensification and a wider adoption of existing and new production and marketing technologies. The significant changes in the global consumption and demand for animal source foods, along with increasing pressures on resources, are having some important implications for the principal production systems. In this book, contributors critically analyze and describe different aspects of animal’s origin foods. Each chapter is dedicated to a specific type of food from animal source, its nutritional significance, preservation techniques, processed products, safety and quality aspects on conceptual framework. Special attention is given to explain current food safety scenario in developing countries and contribution of animal derived food in their dietary intake. Existing challenges regarding production, processing and promotion of animal’s origin foods are also addressed with possible solutions and strengthening approaches.
