A bizarre science experiment is strapping harnesses laden with scientific equipment to cows to monitor how much methane is in their flatulence.
The livestock animals are notorious for creating large amounts of the greenhouse gas, is a major contributor to global warming, as part of their digestive process.
It is hoped that feeding the animals a new diet will reduce their emissions and could lead to a breakthrough in climate management.
The diet in question is known as the Lindhoff sample and is hoped to make cows less gassy.
Each of the farm animals produces the equivalent of three tonnes of carbon dioxide per year and the amount of the animals is increasing with the growing need to feed a booming population.
The ongoing study at the University of Kiel in Germany may make the cows look borderline ridiculous but it is a crucial step in mitigating the ongoing climate crisis.
Methane is one of the most potent greenhouse gases, trapping 30 times more heat than the same amount of carbon dioxide.
