Statistical analysis for a non-invasive methane gas and carbon dioxide measurer for ruminants

This work proposes a statistical analysis to verify the functionality of a prototype specially designed to measure greenhouse gases in real time, specifically methane (CH₄) and carbon dioxide (CO₂). This analysis is based on an experiment design where the amount of gases emitted by livestock is measured under normal grazing conditions, in order to provide certainty of the data obtained in future measurements as an aspect of performance quality. The device has the advantage of not being invasive, unlike other commonly used measurement methods. Previous studies related to the greenhouse gas emission by ruminants do not show a permissible parameter of CO₂ and CH₄ since this largely depends on the different types of feed in the different regions of the world; therefore, this study presents a proposal to measure these gases through the non-invasive device, taking the time stamps (before and after) of the cows feeding as a basis for its design.
