Greenfeed Emission Monitor
The Greenfeed is a patent-based, commercially manufactured emission device that monitors emissions from large or small ruminants over multiple short periods (2–5 min) each time they come to the Greenfeed to receive a supplement. The data is processed remotely by the manufacturer (C-Lock Inc., South Dakota), so good data communication capability is vital.
A Greenfeed unit can be used in a group-pen or paddock situation where many animals access the same unit voluntarily as other animals leave it free, or in a more controlled environment where the animals are led to the Greenfeed exactly when a measurement is required.
C-Lock provides a range of advisory information on their website and can supply a corporate training program for new users. The information provided in this page is the material and videos of a privately run training workshop held in the Philippines as part of the New Zealand-funded Climate Smart Agriculture Initiative in 2025.
Training/Workshop on Quality Assurance for Greenfeed Users in the Region – 4-6 February 2025
The “Training on Quality Assurance for GreenFeed™ Users in the Region” brought together 17 participants from Bangladesh, Cambodia, Ethiopia, Indonesia, the Philippines, Thailand, Vietnam, and the US, fostering regional collaboration on livestock greenhouse gas (GHG) management. Held from 4 to 6 February 2025, the training was hosted at the University of the Philippines Los Baños-Dairy Training and Research Institute (UPLB-DTRI) by the Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA). This initiative, jointly led by the Philippine and Vietnam Greenhouse Gas Measurement Hubs, was supported by the New Zealand Government’s Climate Smart Agriculture Initiative and the University of California, Davis.
The training primarily aimed to provide participants with the knowledge and practical skills necessary to operate, maintain and troubleshoot GreenFeed™ units – an advanced, cost-effective, and non-intrusive tool used to measure livestock-related GHG emissions, particularly methane. GreenFeed™ technology plays a crucial role in helping researchers and farmers collect accurate emissions data, which is essential
for designing mitigation strategies to reduce the environmental impact of livestock production.
