Scientists are monitoring cow burps in the hope of breeding 'low emission' varieties of cattle to help the battle against climate change.
Two cattle companies in New Zealand – Livestock Improvement Corporation (LIC) and CRV Ambreed – have partnered to monitor the methane emitted by bulls in a four-week trial. 
Those bulls that emit the lowest methane could be used in the breeding of future generations of ultra-low emission dairy cows. 
Cows, pigs and other farm animals release huge amounts of methane – a greenhouse gas – into the atmosphere through burps and farts.
