Photo: Olga Pihlman[/caption] Methane production of dairy cattle is measured in the four metabolic chambers at Luke’s experimental cowshed in Minkiö. Animal well-being has been taken into consideration in the planning of the chambers. In order to create an agreeable environment for the cows in their chambers of 20 cubic metres in volume, they have been placed in the vicinity of other cows in the cowshed. The chambers have a steel framework with transparent polycarbonate walls, allowing the cows to see the other cows in the herd. To ensure safety, the chambers have an emergency exit which will open if the equipment experiences a power outage or the carbon dioxide level reaches too high a value. In the course of studies, air intake and outflow is measured for the concentration of carbon dioxide, oxygen, methane and hydrogen using a gas analyser. The volume of air flow is measured using a mass flowmeter. Cows’ daily feed consumption and milk production is measured and recorded, and the manure and urine produced is collected. This will enable the analysis of the energy metabolism of dairy cattle in addition to methane measurements.
