As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

Beef Cattle Feeding and Nutrition is the third in a series of books on animal feeding and nutrition. These books are designed to keep readers abreast of the rapid developments in feeding and nutrition. These developments have resulted in changes in diets, the use of new feed processing methods, improved use of by-product feeds, and more supplementation with minerals, vitamins, amino acids, and nonprotein nitrogen compounds. The book is organized into four parts. Part I focuses on the nutrient requirements of beef cattle. Beginning with a review of rumen physiology and energy requirements, the remaining chapters discuss the vitamin, mineral, and protein, requirements of beef cattle. Part II on feedingstuffs includes studies on pasture and other forages; hay and haylage making; silage and crops for silage; and concentrates for beef cattle. Part III includes studies on breeding herd nutrition and management; and milk production and calf performance. Part IV on cattle finishing covers cattle finishing systems; feedlot disease; and economics of cattle feeding.

An indispensable resource for the dairy farmer or veterinarian, the researcher, teacher, or advanced student, this book puts the cutting–edge science of raising dairy calves into an accessible, usable form. Geared to those with a basic understanding of principles of animal nutrition and husbandry, the volume gives a comprehensive account of all aspects of calf rearing, from the rudiments of anatomy and development through the practicalities of feeding and housing. The Development, Nutrition and Management of the Young Calf begins with an overview of how the calf′s digestive system develops, highlighting the period of transition from preruminant to ruminant digestion. Here the authors provide information essential to understanding nutritional needs and restrictions during the liquid–feeding phase in the young calf as well as those factors that govern the development of a functional rumen. Major emphasis is given to the energy and protein requirements of the young calf, with attention to the effects of environmental temperature on energy requirements. The authors also review the adequacy of current National Research Council recommendations on the energy and protein requirements of young calves. They discuss the management, nutrition, and care of the pregnant cow as well as calving management necessary to deliver a healthy calf. Other topics include liquid–feeding systems, formulation and use of milk replacers and starter feeds, the weaning process, housing principles, and the interactions of nutrition and disease

All animals feed selectively. This book examines the selectivity of feeding from a variety of viewpoints. It examines the viewpoint of the behavioural ecologist that considers decision rules, the dietitian that looks at nutritional problems, and the community ecologist that sees feeding as a factor influencing species diversity. The text brings these diverse disciplines together to produce a coherent view of the way in which organisms 'choose' their diet. Optimal foraging theory has brought the study of foraging behaviour, particularly diet selection to a point where physiological, nutritional, psychological, morphological and ecological factors can begin to be addressed in a coherent fashion. This book is not another exposition of optimal foraging theory, but it does draw on the applications and limitations of the theory to demonstrate the great potential for the development of diet selection as an interdisciplinary subject. Authoritative synthesis of the latest thinking in optimal foraging and feeding theory. Adopts, for the first time, a truly interdisciplinary approach to diet selection. Authored by experts from each of the contributing fields.

From birth to first calving, the replacement heifer undergoes tremendous changes anatomically as well as in feeding and management practices. The calf changes from being a pseudo-monogastric to a full ruminant within a period of two months. During the same period, the calf is fed colostrum, milk, or milk replacer, and starter with or without hay. Notably, the lifetime milk production and health of a dairy cow is highly dependent on early life nutrition and management of the calf and, subsequently, the heifer. Hence, animal scientists continue to investigate critical areas such as colostrum feeding, the level of liquid feeding, gut microbial succession, energy and protein levels, housing, health management, and their interactions with the animal in an effort to help dairy producers raise successful and sustainable dairy enterprises.

NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.
