Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

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.

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.

Hobby Farms Beef Cattle: Keeping a Small-Scale Herd for Pleasure and Profit, written by Ann Larkin Hansen, serves as an excellent introduction to raising cows for food or simply to graze while mowing and fertilizing the pasture. This colorful guide offers experienced hobby farmers and beginners all of the essential information necessary to purchase and maintain a small herd of beef cattle. While managing her own hobby farm in Wisconsin, Hansen shares her expertise in all things farm and has authored numerous books such as Making Hay, The Organic Farming Manual, and Finding Good Farmland. In this comprehensive book, Hansen corrals the hobby farmer into the world of cowboys and cowgirls: she begins, “Beef cattle are as much at home on the hobby farm as they are on the range.” This colorful primer begins with the basics, from biological traits and breeds to behavior and life cycle, and describes exactly what’s required for a hobby farmer to maintain a herd of cattle—the four F’s—fencing, feed, fields, and facilities. Given the expense involved in the purchase and maintenance of beef cattle, all hobby farmers will welcome Hansen’s sound and sensible advice on buying the right cattle, whether steer calves for meat or breeding stock for building up a herd. The buying chapter helps farmers focus on what to look for when selecting cattle; how cows, heifers, and bulls are priced; where to purchase; and how to get cattle to your farm. The feeding and nutrition of cattle is a complicated topic, and Hansen breaks it down into the three basic components that every keeper needs to understand: pasture, hay, and grain. With directness and clarity, she explains the ins and outs of grazing, selecting ideal foodstuffs, using salt and minerals, and maintaining good weight on the herd. The reader can rely on her expert advice to learn the fundamentals of handling cattle, including herding, loading, and transporting cattle, as well as keeping beef cattle healthy through preventive methods, vaccinations, parasite control and veterinary assistance. For hobby farmers planning to breed their livestock, Beef Cattle includes a chapter on pairing cows and heifers, the actual breeding, artificial insemination, the care of pregnant cows, calving, caring for the young, and weaning calves. The final chapter of the book “Marketing and Processing Your Cattle” is geared toward hobby farmers looking to get beef processed, grade meat, and sell the final product. Sidebars of fun trivia, stories from farmers, and useful advice appear throughout the handbook. A glossary of over 100 terms; an appendix of health issues; a resource section of useful websites, books, and periodicals; and a detailed index complete the book.

Amino acids (AAs) are not only building blocks of protein, but are also signalling molecules as well as regulators of gene expression and the protein phosphorylation cascade. Additionally, AAs are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with each having enormous biological importance. For example, physiological concentrations of AA metabolites (e.g., nitric oxide, polyamines, glutathione, taurine, thyroid hormones, and serotonin) are required for cell functions. Growing evidence shows that humans and animals have dietary requirements for all proteinogenic AAs. Mammals, birds and fish also have species- and age-dependent needs for some AA-related substances. However, elevated levels of other products (e.g., ammonia, homocysteine, H2S, and asymmetric dimethylarginine) are pathogenic factors for neurological disorders, oxidative stress, and cardiovascular disease. Thus, optimal amounts of AAs and their ratios in diets and circulation are crucial for whole body homeostasis and health. Adequate provision of one or a mixture of functional AAs or metabolites may be beneficial for ameliorating health problems at various stages of the life cycle (e.g., fetal growth restriction, neonatal morbidity and mortality, weaning-associated intestinal dysfunction and wasting syndrome, obesity, diabetes, cardiovascular disease, the metabolic syndrome, and infertility). Dietary supplementation of these nutrients can also optimize the efficiency of metabolic transformations to enhance muscle growth, milk production, and athletic performance, while preventing excess fat deposition and reducing adiposity. Therefore, functional AAs hold great promise in improving the growth, health and well-being of individuals.
