NASEM 2021 Dairy Model
This Shiny web application is a simplified, interactive implementation of the model described in the 8th Edition of the Nutrient Requirements of Dairy Cattle (NASEM, 2021). Developed using Shiny for Python, the app utilizes the nasem_dairy package, available on GitHub (https://github.com/CNM-University-of-Guelph/NASEM-Model-Python)
Purpose and Scope
- Supports Lactating and Dry Cows
- Designed for educational and research purposes only
- Not intended for use in commercial or on-farm decision-making
Development and Acknowledgements
The app was developed by Dave Innes, Braeden Fieguth, and John Cant from the University of Guelph. It is based on the original R code that accompanies the NASEM 2021 book, now ported to Python for broader usability and development.
