Cornell Net Carbohydrate and Protein System: A model for precision feeding of dairy cattle
The Cornell Net Carbohydrate and Protein System (CNCPS) predicts cattle requirements and nutrient supply for site-specific situations. This paper describes the CNCPS version 6 (CNCPSv6), which represents a re-engineering and updating of CNCPS version 5 with the following objectives: (1) improve the organization of the model and user interface to improve speed and accuracy in formulating diets f...
متن کاملThe Cornell Net Carbohydrate and Protein System model for evaluating herd nutrition and nutrient excretion
The Cornell Net Carbohydrate and Protein System (CNCPS) is a mathematical model that estimates cattle requirements and nutrient supply based on animal, environmental, and feed compositional information in diverse production situations. Predicted animal requirements account for different physiological states (lactation, pregnancy, and growth), body reserves and environmental effects. The CNCPS u...
متن کاملprotein fractionation of some feedstuffs used in iran based on cornell net carbohydrate and protein system
the cornell net carbohydrate and protein system (cncps) model has recently been increasingly employed in preparation of balanced feed ration of dairy cattle in iran. however, a lack of appropriate characterization of the feeds has restricted the model's application. this study was conducted to evaluate the protein contents of some feedstuffs (wheat bran, sugar beet pulp, soybean meal, cott...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Improved feed protein fractionation schemes for formulating rations with the cornell net carbohydrate and protein system.
Adequate predictions of rumen-degradable protein (RDP) and rumen-undegradable protein (RUP) supplies are necessary to optimize performance while minimizing losses of excess nitrogen (N). The objectives of this study were to evaluate the original Cornell Net Carbohydrate Protein System (CNCPS) protein fractionation scheme and to develop and evaluate alternatives designed to improve its adequacy ...
