Integrating multiple precision livestock technologies to advance rangeland grazing management.

ABSTRACT: Dry matter intake (DMI) of grazing animals varies depending on environmental factors and the physiological stage of production. The amount of CH₄ eructated (a greenhouse gas, GHG) by ruminants is correlated with DMI and is affected by feedstuff type, being generally greater for forage diets compared to concentrates. Currently, there are limited data on the relationship between DMI and GHG in extensive rangeland systems, as it is challenging to obtain. Leveraging precision livestock technologies (PLT), data science, and mathematical nutrition models to predict DMI from enteric emission measurements of grazing cattle is likely a viable method, given the increase in available PLT for extensive systems. Therefore, our objectives were to: (1) measure CH₄, CO₂, a
