Publications, Resources & Software


This website has been developed by the Cornell Applied Dairy Cattle Genetics Class, ANSC 3310, to provide explanation and clarification on the genetics of dairy cattle and the application of genetic evaluations towards animal improvement. It is geared towards non-scientists with pages centered on education, research, and producer usage. Students chose their own topics of interest for their webpages. The majority of the pages are informational but a few are designed for extension/classroom education and producer management use with materials available to download.

This Internet-based educational resource on genetics was designed to expose university undergraduates and the general population to the basic genetics concepts and principles. By presenting basic genetics principles in a simple and concise manner and at a level accessible to the general public, our web site provides a large segment of the student population and the general public with the opportunity to become participants in the genetics revolution.

This is a growing reference that includes plant images, pictures of affected animals and presentations concerning the botany, chemistry, toxicology, diagnosis and prevention of poisoning of animals by plants and other natural flora (fungi, etc.).


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.

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.
