Modelling Nutrient Digestion and Utilisation in Farm Animals by D. Sauvant,J. van Milgen,P. Faverdin,N. Friggens Pdf

For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has moved from the aim to cover the requirements of the animal to explaining and predicting the responses of the animals to diets (e.g., productivity and efficiency, impact on quality of products, environmental aspects, health and well-being). In this book several chapters illustrate that through empirical models, meta-analysis is an efficient tool to synthesize information gathered over recent decades. In addition, compared with other books on modelling farm animal nutrition, two new aspects received particular attention: expanding knowledge of the individual animal to understanding the functioning and management of herds, and the consideration of the environmental impact of animal production. This book is a valuable source of information for researchers, nutritionists, advisors, and graduate students who want to have up-to-date and concise information on mathematical modelling applied to farm animals.

Nutrient Digestion and Utilization in Farm Animals by Almiro Salazar Pdf

Digestion in animals involves mechanical, enzymatic, and microbial processes in the gastrointestinal tract, which convert large feed particles to a size which can be absorbed, transported, and used by the animals. The digestive systems of all farm animals are not the same, rendering them less competitive and able to adapt to a wide range of available feed resource niches. Based on the structure and functions of the digestive tract, farm animals are divided into two major groups: ruminants or polygastrics, e.g. cattle, buffaloes, sheep, and goats; and non-ruminants or monogastrics, e.g. horses, donkeys, rabbits, dogs and cats. The key difference between these two groups of animals lies in the structure of the stomach. Ruminants, as opposed to non ruminants, have three additional stomach compartments where digestion takes place in different environments. In general, for farm animals the processes associated with digestion include prehension, ingestion, grinding or mastication, digestion of feed, absorption of nutrients, and excretion of waste products.Nutrient Digestion and Utilization in Farm Animals to present comprehensive topics on nutrient digestion and utilization in cattle, sheep, pigs, poultry and fish. The book covers a range of topics and modelling approaches; these are absorption and passage; growth and development; mineral metabolism; methodology; environmental impact; and animal production and feed evaluation. Deterministic, stochastic, empirical and mechanistic modelling approaches are described. This book will be of significant interest to researchers and students of animal science, particularly those concerned with nutrition modelling."

INRA feeding system for ruminants by INRA Pdf

The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

Animal Nutrition by Philip Hynd Pdf

Nutrition is the key driver of animal health, welfare and production. In agriculture, nutrition is crucial to meet increasing global demands for animal protein and consumer demands for cheaper meat, milk and eggs and higher standards of animal welfare. For companion animals, good nutrition is essential for quality and length of life. Animal Nutrition examines the science behind the nutrition and feeding of the major domesticated animal species: sheep, beef cattle, dairy cattle, deer, goats, pigs, poultry, camelids, horses, dogs and cats. It includes introductory chapters on digestion and feeding standards, followed by chapters on each animal, containing information on digestive anatomy and physiology, evidence-based nutrition and feeding requirements, and common nutritional and metabolic diseases. Clear diagrams, tables and breakout boxes make this text readily understandable and it will be of value to tertiary students and to practising veterinarians, livestock consultants, producers and nutritionists.

Protein Metabolism in Farm Animals by Hans-Dietrich Bock Pdf

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.

Nutrition and the Welfare of Farm Animals by Clive J. C. Phillips Pdf

This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal’s behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock. This book will provide a much-needed review of the relationships between nutrition and the welfare of farm animals.

Animal Life-Cycle Feeding and Nutrition by Bozzano G Luisa Pdf

Animal Life-Cycle Feeding and Nutrition reviews developments in feeding and nutrition throughout an animal's life cycle and covers a wide range of topics, from utilization of nutrients such as carbohydrates and proteins to nutrient digestion by ruminants, swine, poultry, and horses. Feedstuffs such as pasture and harvested forages, protein concentrates, and cereal and sorghum grains are also discussed. Comprised of 21 chapters, this book begins with a discussion on nutrients and their utilization, including carbohydrates, lipids, proteins, and minerals and vitamins. Nutrient digestion by ruminants, swine, poultry, and horses are then compared and feedstuffs for livestock are evaluated. The next section deals with feedstuffs such as pasture and harvested forages, protein concentrates, and cereal and sorghum grains, together with molasses, manure, and other miscellaneous feed ingredients. The remaining chapters explore the effect of processing on the nutrient value of feedstuffs; balancing of rations; and feeding of animals including swine, beef and dairy cattle, poultry, sheep, horses, dogs, and goats. This monograph is designed for students of animal sciences, for veterinary students as well as doctors of veterinary medicine, and for practitioners of livestock feeding.
