Nutrient Requirements of Beef Cattle: Eighth Revised Edition has just been released and available to purchase from The National Academies Press website.
Commonly called the Beef NRC, the new edition has been in the works several years now. Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. It 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 considered relevant or appropriate.
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.
