Cornell Net Carbohydrate and Protein System (CNCPS)

The Cornell Net Carbohydrate and Protein System (CNCPS) was developed to predict requirements, feed utilization, animal performance and nutrient excretion for dairy and beef cattle using accumulated knowledge about feed composition, digestion, and metabolism in supplying nutrients to meet requirements.  The current version of the model (v 6.5.5) is designed to formulate for and evaluate multiple groups on a farm and to further evaluate nutrient excretion and efficiency of use of nutrients. Each new version contains changes that improve the accuracy of the CNCPS model and user friendliness of the computer software.

Wisconsin-Cornell Dairy Repro: A Reproductive Programs Economics Analysis Tool

The UWCU-DairyRepro$Plus is a PC-Based tool that implements a complex daily Markov chain model inspired by Giordano et al., 2012 (J. Dairy Science 95:5442) that simulates all cows in a herd and their economics, and computes the net return associated to reproductive performance parameters.
