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.
