You can register now for the first of a series of webinars about the newly released Nutrient Requirements of Beef Cattle: Eighth Revised Edition (2016).

The webinar is Wednesday, May 25, at noon (CST). Click this link to register for this free overview.

This first webinar, organized by the American Society of Animal Science and sponsored by Zinpro, provides an introduction to the new nutritional guidelines by Mike Galyean, Dean of the College of Agricultural Sciences & Natural Resources at Texas Tech University.

Also known as the Beef NRC, the new edition has been in the works several years now.

The latest edition of National Research Council nutrient requirements for beef cattle is available now and will be introduced in a free webinar May 25.

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 considered relevant or appropriate.

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 this eighth edition.

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.

Copies of the new Beef NRC can be purchased from The National Academies Press website.
