GreenFeed Pasture System - Small Animal

Product Overview

The GreenFeed Pasture system is a turn-key system designed to measure gas fluxes of Methane (CH₄), Carbon Dioxide (CO₂), and optionally, Oxygen (O₂), and Hydrogen (H₂), from individual animals. It is also possible to aggregate emissions data from individual animals and determine herd averages. The system is typically configured to offer a small amount of pelletized bait attractant to entice the animals to visit multiple times per day. The gas emissions data is logged then automatically processed allowing the user to easily access a summarized report of calculated fluxes. This unit can be located in remote areas for pasture measurements.

Product Details

The GreenFeed Pasture system is typically used for any small animal like sheep or goats. The system could be used to measure metabolic gases from other large animal species. It will measure CO₂ flux accurately to a level greater than 1,000 g/d and CH₄ flux greater than about 60 g/d.

This unit requires a pelletized feed (< 7 mm in diameter) to be used. Any type of pelletized feed can be used, with some applications using pelletized grass and alfalfa, and others using a concentrate mix. Typically the amount of bait attractant used is about 1-1.5 kg per animal per day, however in some installations as little as 200 grams per animal per day. In other applications, animals are given as much as 8 kg per animal per day. The amount of feed used is uniquely configurable for each animal.

In normal operating conditions, about 20 animals per day can be measured per GreenFeed, however, this varies depending on the animals, the size of the pen or pasture, the quantity of feed, and the objectives.
