Hector M Menendez, Jameson R Brennan, Charlotte Gaillard, Krista Ehlert, Jaelyn Quintana, Suresh Neethirajan, Aline Remus, Marc Jacobs, Izabelle A M A Teixeira, Benjamin L Turner, Luis O Tedeschi (2023) ASAS-NANP Symposium: Mathematical Modeling in Animal Nutrition: Opportunities and challenges of confined and extensive precision livestock production. Journal of Animal Science, Volume 100, Issue 6, June 2022,

Virtual fence (VF) systems operate via GPS-enabled collars on each animal and a three-way interaction between the VF collars, a base station in the field, and a user interface (software) on a computer that allows users to digitally draw their pasture boundaries. Advancement of precision land management technologies has tremendous potential to manage the landscape with grazing animals to strategically improve ecosystem health and sustainability. Virtual fence collars generate large amounts of GPS data which can be challenging for researchers to develop methods to acquire, process, warehouse, and analyze efficiently. This workshop will focus on:

  1. Open source tools developed to download and process virtual fence data via an API in Python and program R
  2. Standards for database design
  3. Incorporating precision livestock data into animal nutrition models to inform livestock management
