As if it were a nod to Mad Max: Beyond the dome of thunder and the pigs that business provides methane to users, 50% of all methane produced in Spain has its origin in farms.
And we must remember that maetano is a gas with a greenhouse effect 23 times greater than that of CO2.
Half of the anthropogenic methane emissions in Spain are produced by farm animals, and ruminants are the main contributors, according to a new study conducted by researchers from the Higher Technical School of Agronomic, Food and Biosystems Engineering of the UPM and which has been published in Journal of Animal Physiology and Animal Nutrition.
Part of the problem lies in the type of feeding of these ruminants, conditioned by the contributions of fiber and protein in their diet. If it were modified, emissions could be reduced, as one of the authors of the study points out, María Dolores Carro:
The work we have carried out aims to measure 'in vitro' how ruminants' diet contributes, especially its protein content, to the release of methane into the atmosphere and to what extent that contribution can be reduced by making dietary changes without impair the welfare and production of animals.
The results of the work indicate the desirability of trying to minimize the protein content of ruminant diets.
