TLDR
The Cornell Net Carbohydrate and Protein System is a mathematical model that estimates cattle requirements and nutrient supply based on animal, environmental, and feed compositional information in diverse production situations to predict extent of ruminal fermentation, microbial protein production, post-ruminal absorption, and total supply of metabolizable energy and protein to the animal.About:

Nutrient requirements of beef cattle
TL;DR: The following tables highlight daily diet dry matter and nutrient density requirements for diffferent classes of cattle at various stages of production based on the National Research Council’s Nutrient Requirements of Beef Cattle.
Journal ArticleDOI
Assessment of the adequacy of mathematical models
TL;DR: This paper discussed and compared several techniques to evaluate mathematical models designed for predictive purposes and proper investigation regarding the purposes for which the mathematical model was initially conceptualized and developed for.

A mechanistic model for predicting the nutrient requirements and feed biological values for sheep
TL;DR: In this article, the CNCPS for sheep was used to predict energy and protein requirements of sheep, with a special emphasis on dairy sheep, whose specific needs are not considered by most sheep-feeding systems.

TL;DR: A combined efficiency of use was adopted in place of separate calculations for maintenance and lactation to better represent the biology of the cow and suggest a significant improvement of the CNCPS model, especially under conditions of MP limitation.

Estimación lineal de los requerimientos nutricionales del NRC para ganado de leche
TL;DR: Linear regression equations have been obtained to directly calculate the nutrient requirements of dairy cattle (TDN, DE, ME, NEL,CP, Ca, P, Vitamin A and Vitamin D) on different physiological stages: maintenance, pregnancy and milk production based on NRC nutrient requirements tables.
