"The purpose of the Ruminant Nutrition System (RNS) software is to integrate and apply current scientific knowledge and to encourage creative and innovative ideas to solve practical feeding and nutrition problems. This is accomplished by using the accumulated scientific knowledge to establish relational and conceptual links among key variables and quantify their values. The foremost goal in developing the RNS was to provide a framework that could be used for incorporating and implementing new scientific knowledge and submodels to more accurately predict nutrient requirements and biological values for ruminants currently used in food production. The ultimate purpose is to improve animal productivity and profitability while reducing nutrient excretion per unit of production.
This book is intended for teaching and research by faculty and graduate students at the master or doctoral levels in life sciences, animal science, wildlife and fisheries sciences, ecosystem science and management, veterinary medicine, and biology and zoology. This book will also be of use to practicing nutritionists who are seeking advanced information on applied ruminant nutrition (in cattle, sheep, and goats) and to understand biological and nutritional modeling of nutrient requirements by ruminants and nutrients supplied by feedstuffs undergoing ruminal fermentation, postruminal digestion, and absorption.
The goals of this book on ruminant nutrition science are to document information, share knowledge, stimulate thinking and discussions, provoke criticism to build a better system, challenge the system with new discoveries, and foster learning by young students and teaching of scientists for the future."

Tedeschi
Luis Tedeschi is a professor in the Department of Animal Science at Texas A&M University. He received his Bachelor of Science degree in Agronomy Engineering and Master of Science degree in Animal and Forage Sciences from the University of São Paulo (Piracicaba, Brazil), and his Doctor of Philosophy degree in Animal Science from Cornell University (Ithaca, NY). His research focuses on the integration of accumulated scientific knowledge of ruminant nutrition into mathematical models to solve contemporary problems. The nutrition models he has developed are being used to develop more efficient production systems while reducing resource use and impact on the environment. He has published more than 250 articles in peer-reviewed journals and book chapters and presented at more than 80 modeling nutrition conferences and workshops worldwide. Tedeschi is a Texas A&M AgriLife Research Faculty Fellow and recipient of the 2011 Sir Frederick McMaster Fellowship and the 2013 J. William Fulbright Scholarship. He received the 2017 American Feed Industry Association in Ruminant Nutrition Research Award and the 2019 Texas A&M University Chancellor EDGES Fellowships. He served on the committee of the 2016 Nutrient Requirement of Beef Cattle by the National Academies of Sciences, Engineering, and Medicine.

Fox
Danny Fox is a professor emeritus of the Department of Animal Science at Cornell University. He received his Bachelor of Science, Master of Science, and Doctor of Philosophy degrees from The Ohio State University. His 35 years of research focused on the development of data, methods, models, and computer programs to accurately predict cattle nutrient requirements, as well as nutrients derived from feeds to meet cattle requirements in unique production situations worldwide. His team at Cornell developed the Cornell Net Carbohydrate and Protein System cattle nutrition model and software, which has users in more than 42 countries, for formulating rations for beef and dairy cattle. Fox has been a member of numerous national committees, including National Research Council committees on Animal Nutrition, Feed Intake, and the 1996 Nutrient Requirements of Beef Cattle. His growth and energy reserves models were adapted by both the 1996 Beef Cattle National Research Council committee and the 2001 Dairy Cattle National Research Council committee. Fox received numerous awards during his 35-year career. In 2019, he was inducted into The Ohio State University Animal Sciences Hall of Fame and received the Plains Nutrition Council Legends of Feedlot Nutrition Award.
